Hey guys, tonight we’re diving deep into 
one of history’s strangest rabbit holes.   The world of medieval royalty and what happens 
when you keep marrying your cousins for a few too many generations. Spoiler alert, it’s not 
good. You probably won’t survive this journey genetically speaking, but it is fascinating. 
So, before you get comfortable, take a moment   to like the video and subscribe, but only if 
you genuinely enjoy what I do here. I’m curious, what city are you listening from tonight? And 
what time is it where you are? Drop it in the   comments. I love seeing how far this sleepy little 
history community stretches. Now, dim the lights, maybe turn on a fan for that soft background hum. 
And let’s ease into tonight’s journey together. Picture this. The crackling of fire in a stone 
hall, flicker of candle light catching on silver goblets, and a young noble woman in velvet robes 
being introduced to her future husband who is also casually her cousin or her uncle or her nephew. 
Welcome to the elite world of medieval European aristocracy where bloodlines mattered more than 
biology and love had absolutely nothing to do with marriage. The term inbred carries a punch today. 
But in the medieval context it was strategy. Dynasties like the Habsburgs, the Capescians, and 
the Tresemmaras didn’t just intermar for fun. They did it to hoard power, land, and legitimacy. 
If you marry your cousin, you don’t lose any castles. If you marry a foreigner, suddenly 
someone else is raising your heir in a rival   kingdom. So the logic was clear, even if the 
consequences weren’t. Yet over generations, that logic led to genetic whirlpools that birthed 
some of the most fascinating and tragic figures in European history. You’re going to meet women 
tonight who are daughters of double first cousins, nieces married to their uncles, and sisters 
married off to their first cousin once removed. These aren’t just mathematical absurdities. 
They were real women with complicated lives, deep loyalties, and sometimes shocking symptoms of 
what happens when your DNA plays the royal version of musical chairs. We’ll visit stone palaces in 
Spain, gloomy castles in Austria, and glittering courts in France and the Low Countries. You’ll 
watch as empires rise and fall around these women, many of whom, let’s be honest, never got a say 
in the matter. Take the Hapsburgs for instance,   the undisputed champions of European inbreeding. 
Their family tree isn’t so much a tree as a wreath. They built a global empire on marriages. 
Each one drawing the family net tighter until it practically strangled itself. The mall will 
spend time with some of the more infamous male   Habsburgs later. It’s the women who carried 
the generational load both politically and genetically. These women were the mothers 
of kings and queens, the breeders of empire,   and the unfortunate bearers of some truly unlucky 
traits. But it wasn’t just the Habsburgs. The Capichians of France, the trstamaras of Spain, and 
even the Plantaginets of England dipped their toes in the same shallow gene pool. The goal was always 
the same. Consolidate claims, prevent civil war, and lock down dynastic legitimacy. But with that 
came feuds, forced marriages, and a trail of noble women who spent their lives navigating a world 
where family meant everything and meant way too   much. What’s wild is how obvious some of the 
side effects became over time. Elongated jaws, fertility issues, recurring mental illness, still 
births, and strangely shaped skulls pop up again and again in royal lineages. Yet, nobody seemed 
all that eager to change course. Even the church, which technically forbade incestrous marriages 
past a certain degree, made exceptions for royals. The Pope would often grant a dispensation, 
basically a holy permission slip, for yet another cousin marriage, as long as it kept the 
peace. Here’s the kicker. Modern geneticists have actually studied some of these lineages and 
confirmed what those medieval matchmakers refused   to see. Inbreeding coefficients, yes, that’s a 
thing, are measurable. And several royal offspring had scores comparable to the children of sibling 
unions. One of the highest ever recorded, Charles II of Spain, whose tragic tale will save for the 
end. But spoiler, he couldn’t chew food properly, couldn’t walk without help, and likely had the 
mental development of a 5-year-old, and yes,   he had a lot of aunts and uncles who were also 
his cousins. Of course, not every royal woman with a tangled ancestry suffered overtly. Some were 
brilliant rulers, effective diplomats, and adored queens. One of the fringe debates among historians 
today is just how much inbreeding actually influenced personality or mental stability. For 
example, was Joanna, the mad of Castile, actually insane, or just caught in a brutal political trap 
where her erratic behavior was exaggerated to keep her from ruling? Was her daughter’s melancholy 
a symptom of family genetics or the result of a lifetime trapped between power and duty? This 
kind of question pops up a lot when you start pulling threads on these women’s lives. How much 
was nature and how much was nurture? These women weren’t just passive figures. They were queens, 
regents, and mothers shaping the future of   empires. Some of them ruled directly, others ruled 
through their sons or husbands, and they all bore the burden of dynastic duty in a way their male 
counterparts didn’t. A prince might go off to war or drink himself to death, but a princess was 
expected to marry whomever the crown required and produce heirs, no matter how many miscarriages, 
deformities, or depressions came along the way. In the next sections, we’ll meet specific women 
whose stories exemplify this strange intersection of politics, genetics, and deeply personal 
struggle. You’ll follow Isabella of Habsburg as her bloodline loops inward, Joanna of Castle 
as her sanity is questioned, and Elellanena of   Portugal as she marries her own uncle to cement 
imperial power. Along the way, we’ll sprinkle in facts you’ve never heard before, like which 
queen’s jaw had to be redrawn in official   portraits, or which princess was technically her 
husband’s great aunt. So, buckle up gently. The next few hours might just make you grateful for 
your boring, unroyal DNA. So, let’s head straight into the tangled tapestry of inbred nobility with 
a woman who is practically the poster child for what happens when your entire family tree folds 
in on itself like an origami disaster. Isabella of Habsburg. If you’ve ever wondered what it’s 
like to be the result of multiple generations of cousin marriages, well, meet Isabella. She 
doesn’t just belong to the Habsburg dynasty. She is the Habsburg dynasty rolled up into one 
velvet draped highly ceremonial genetic loop. Born in 1501, Isabella was the daughter of Philip 
the Handsome and Joanna of Castl aka Joanna the man who we’ll meet properly in the next section. 
For now, just note that Isabella’s parents were both grandchildren of the same royal couple. John 
the Tetan second of Aragan and Isabella first of Castile. That means Isabella’s family tree was 
already bending awkwardly and on itself from the   moment she cried her first baby cry in Brussels. 
And by the time she reached marrying age, round 13, because of course she did, her value 
wasn’t about her smile or her charm. It was all about the blood, that Habsburg blood. She was 
married off to Christian 2 of Denmark, Norway, and Sweden. A man described by contemporaries as 
Mccurial, which is a polite way of saying he was probably a bit of a nightmare. Their marriage 
was political like every marriage of the age,   but it also had an edge of desperation. Christian 
needed allies and the Habsburgs needed influence in Scandinavia. Isabella was the literal body 
through which that influence would flow. Her uterus was now official royal policy. Here’s where 
it gets complicated, because of course it does. Christian wasn’t exactly stable. He was charming 
at times, yes, and he clearly liked Isabella, but he also had a favorite mistress, Dava Sigbrit, 
whom he refused to abandon even after marrying the Habsburg princess. Diva was lowborn, not even 
nobility. And Isabella had to sit there in her Danish castle, pregnant with the future, while 
her husband prayed at his mistress to round court like a new horse. That must have stung, even for 
someone raised to accept political marriages as part of the royal gig. But Isabella held her own. 
She bore Christian six children, three of whom survived infancy, which in itself was a miracle 
given the gene pool and the general medieval lack of sanitation. One of her sons, John, would have a 
short life, but her daughter, Doraththa, would go on to marry another cousin naturally. Isabella’s 
influence at court grew, particularly after DevC died suddenly. Maybe from poisoned cherries, maybe 
not. The truth is murky, and so are the rumors. Some whispered that Isabella or her allies 
had a hand in it, but there’s no hard proof,   just a sudden vacancy in the royal mistress role 
and a queen who stepped up into real power. And yet, the genetic weight of her ancestry didn’t 
disappear. Isabella herself suffered from bouts of illness that some historians now think might have 
been linked to hemophilia or a similar inherited   disorder. She died young, just 24 years old. The 
official cause, a sudden illness. Medieval catch all term for anything from tuberculosis to a 
stroke to well inherited genetic dysfunctions we can’t pin down from the comfort of our modern 
armchairs. A quirky fact about Isabella’s brief life. She was fluent in at least five languages 
thanks to her Habsburg upbringing. These weren’t I can ask where the bathroom is skills either. 
She could hold diplomatic conversations in Latin,   Castellian, Flemish, French, and German. Her 
letters reveal a sharp mind, a touch of sarcasm, and a keen understanding of the politics around 
her. She wasn’t just a vessel for babies. She was aware of the chessboards and moved across 
it as much as her gender allowed. Now,   here’s where scholars still butttheads. Was 
Isabella a victim of her family’s obsession with purity or simply unlucky in a dangerous 
age? Some point to her children’s weak health and her own early death as clear signs of genetic 
fragility. Others argue that early mortality was just part of the courts in the 16th century, even 
for royals. And while that’s true to an extent, the Habsburg’s increasingly closed breeding 
circles make the debate harder to ignore. What’s   not debated is this. Isabella’s children carried 
forward even more concentrated royal blood, making the next generation of Habsburgs even more 
genetically enclosed. her grandson, Maximleian II, would marry his first cousin. And their children, 
well, let’s just say their jaw lines could cut glass, and not in a good way. One eerie thing of 
Andrew Isabella’s life is how quiet it feels in retrospect. She’s one of those queens you rarely 
hear about unless you go looking. No big wars, no grand scandals, no famous paintings, and yet her 
DNA echoes all through European history. Her blood ran in the veins of emperors, kings, and doomed 
heirs. If power in this world can be measured by   legacy, then Isabella was more powerful than most 
of the men around her. She just didn’t get a crown to show it. You almost want to go back in time 
and whisper to her through the veil of centuries   v. Hey, maybe skip that cousin. Maybe tell your 
daughter to try someone new, like someone not related. But you know, she couldn’t. That was the 
game, and she played it as well as anyone with her last name could. From the quiet courts of Denmark 
to the loud echoes of donastic strategy, Isabella of Habsburg’s life is one of the clearest examples 
of what happens when royalty values family ties just a bit too much. She didn’t live long, but 
what she passed on would shape Europe for the next   two centuries. And a lot of those results weren’t 
exactly healthy. Now that you’ve met Isabella of Habsburg, it’s time to step even deeper into the 
foggy Gothic corridors of Royal Heredity and meet her mother, Joanna of Castile. Or, as she’s better 
known in the history books, Joanna the Mad. You’ve probably heard the nickname before. Maybe you 
picture her wandering a castle barefoot, mumbling   to herself or clutching her dead husband’s coffin 
like a morbid romantic. And yeah, some of that actually happened. But the full story of Joanna, 
it’s less madness, more tragedy with a generous sprinkle of donastic pressure and of course a 
heavy dose of concentrated family genetics. Joanna was born in 1479 to Ferdinand II of Araggon and 
Isabella I of Castile, Spain’s power couple, the Catholic monarchs who unified the Spanish kingdoms 
and sponsored a certain Christopher Columbus.   Their marriage was the ultimate political power 
move and there they wanted their children to follow suit. Joanna was their third child, smart, 
reserved, and devout, with eyes that reportedly smoldered when she was angry. But there was one 
catch. Her family tree already had that classic   royal kink. Her parents were second cousins. 
Not a terrible start by medieval standards, but the signs of internal looping were starting to 
flicker. As a young woman, Joanna was shipped off to Flanders to marry Philip the handsome. Yes, 
that’s literally what they called him. And yes,   it was mostly for politics. Philip was the 
son of Holy Roman Emperor Maxmillian Fuls and Mary of Burgundy. And this union was meant to 
forge a powerful European alliance. But unlike many arranged royal marriages, Joanna and Philip 
were weirdly into each other. Like passionately, obsessively into each other at first. The kind 
of chemistry that raised eyebrows are caught. You might think, “Oh, that’s sweet.” But 
this is a bedtime history, not a fairy tale, so you know what’s coming. Philip was charming, 
ambitious, and very aware of his own good looks. Joanna deeply himself became intensely jealous, 
especially once Philip began openly cheating on her. She would reportedly scream and throw things 
and demand to know the names of his mistresses. Court rumor had it that she once attacked a lady 
and waiting with scissors over a flirtatious   glance. Was she mentally ill or just a woman 
pushed to the edge in a world where her power was always second to her husband’s pleasure? Things 
only got worse when her mother, Queen Isabella, died and Joanna became queen of Castile. On paper, 
this should have made her one of the most powerful women in Europe. But Philip wasn’t having it. 
He tried to muscle in as king, claiming Joanna was too unstable to rule. Her father, Ferdinand, 
did the same thing. Both men wanted control over Castile, and both used Joanna’s supposed 
madness as an excuse to take it from her. What followed was a slow, relentless campaign 
to paint her as unfit, a narrative that stuck, partly because it was convenient and partly 
because Joanna did start to show signs of   emotional collapse. After Philip’s sudden death 
in 1506, he reportedly drank cold water after playing a vigorous game of ball and it shocked 
his system, which yeah, sounds fake. Joanna’s grief became extreme. This is where the famous 
coffin story comes in. She had his body embarmed, refused to bury it for years, and traveled with 
the casket across Castile, stopping at monasteries and demanding prayers for his soul. Some say she 
opened the coffin periodically to gaze at him. Others claim she refused to allow any women near 
it, fearing they might seduce his corpse. Okay, that part does edge into mental illness territory, 
but hold on. This is where modern historians start eyeing the narrative. Yes, Joanna’s behavior was 
eccentric, even disturbing. But was it madness or grief weaponized by power-hungry men? She 
had just lost her husband, was being isolated from her children, and had everyone around her 
gaslighting her into thinking she was unwell. Even her attendants were under orders to keep 
her under control. When you’re locked away in   a cold castle with no friends, no allies, and a 
lifetime of dynastic expectation weighing on you, madness might just be the only way out. Here’s 
the genetic kicker. Joanna’s parents were related, sinned, and her husband was her second cousin. 
Their child, Isabella, from the last section, was part of a lineage that was now officially 
swirling in on itself. You can track your Anna’s   bloodline straight down to Charles the second 
of Spain, whose family tree looks like a family tumble weed. Also, here’s a fringe fact you’re not 
going to hear in most textbooks. Some 16th century doctors actually believe that uterine misalignment 
caused female madness, as in they thought her womb had literally traveled to her head. No joke, one 
account from a Spanish physician describes Joanna as being afflicted with a wandering womb, which 
they thought caused her hysteria. The solution? Herbal compresses, prayer, and once, wait for 
it, a suggested exorcism. Modern scholars love to debate whether Joanna really had what we’d 
now call bipolar disorder or schizophrenia or whether she was a victim of socopolitical abuse. 
One particularly interesting theory suggests she may have had a form of post-traumatic stress 
disorder brought on by constant betrayal and   the deaths of her children. Because yes, while 
she was confined in toas for nearly 50 years, her children died one by one, usually far from 
her. She was denied the chance to raise them, see them, or even grieve them properly. And 
yet, through all this, she remained technically   queen of Castile. Her signature still sealed royal 
decrees. Her presence still mattered, if only as a figurehead. And the dynasty rolled on through her 
blood and her heartbreak. So, what’s the takeaway here? Joanna wasn’t just the mad one. She was 
the product of strategic imbreeding, the porn of rival male egos, and maybe, just maybe, a woman 
who saw too much and cracked under the pressure. But her legacy didn’t crack. Her children would 
go on to shape Europe, and her story remains one of the most haunting examples of what happens 
when you mix too much royal blood with too little compassion. Next, we’ll meet another woman from 
the royal bloodline tangled in its own reflection, Blanch of Castile, who finds herself caught in 
the pushpull of French and Spanish dynasties. But first, let Joanna linger in your mind for a 
moment, alone in a fortress, her world shrinking, her love unburied, her name etched into history, 
not for what she did, but for what they said she was. Now your eyes drift toward another castle 
corridor, lit by a flickering rush light and echoing with footsteps that trace centuries old 
ambitions. Tonight we cross the Pyrenees into a tale not quite as Gothic as Joanna’s, but every 
bit as woven with domestic pressure and genetic deja vu. Meet Blanch of Castile. She doesn’t get 
the kind of historical spotlight that queens like Elellanena of Aquitane or Katherine Demedy bast 
in. But don’t let that fool you. Blanch was a lynch pin in one of Europe’s most tangled noble 
nets. And like many royal women of the time,   she was born into a family already looping back 
in on itself. Blanch came into the world in 1188, the daughter of King Alonso VII of Castile and 
Elellanena of England. Yes, that Elellanena, daughter of Henry II and Elellanena of Aquitane. 
That made Blanch a granddaughter of two powerful dynasties. Her blood was a potent blend of English 
plantaginate ambition and Spanish trstamora pride. It also meant her family tree had already begun 
its slow spiral because the Castellian and French royal lines weren’t shy about marrying cousins 
when it kept power close. At the age of 12, Blanch was sent off to France to marry Louie, 
the son of King Philip II. But hang on, she wasn’t actually the original choice. The French 
had originally wanted her sister tier Uraka, but when a lastminute switch up happened, one 
that scholars still squint at with suspicion,   Blanch was plucked instead. Why the change? Some 
say Oraka was too Spanish, or that Blanch simply had a better temperament. Others hint at something 
less flattering. Iraqa may have shown signs of inherited instability, and the French crown didn’t 
want to risk it. Whether that’s true or just a smear campaign cloaked in diplomacy, we’ll never 
know for sure. Blah married Louis VII of France in 1200 and quickly proved herself far more than 
a ceremonial wife. When Louisie became king, she stepped up not just in courtly presence but as a 
political force. And when he died in 126, leaving their son Louis the 9th, later St. Louis, as a 
boy king of 12, Blanch didn’t blink. She declared herself a regent and ran France like a queen who’d 
been waiting her whole life for the chance. than she had. While other women were sewing tapestries 
and birthing heirs, Blanch was drafting treaties, intimidating baronss, and keeping the fragile 
Capitian hold on France intact. But here’s the part we’re here for. Blanch’s bloodline. She and 
Louis VI were third cousins, close enough that the church had to grant a dispensation for the 
marriage. It wasn’t exactly scandalous by the   standards of the day, but it was part of a growing 
pattern of dynasties interweaving themselves so tightly that marriage options became less about 
finding a match and more about finding someone   you weren’t related to. And with Blanch, that 
issue just kept compounding. She had 13 children, though only a few survived to adulthood. Louis the 
9th, of course, became a king and later a saint, but scholars have often pointed out that several 
of his siblings had health problems or died young. common, yes, but statistically higher than normal 
even for the time. One theory suggests Blanch and Louisa’s shared plantachinate ancestry may have 
carried some form of inherited immune weakness, though this remained speculative. Another quirky 
rumor that Blanch was so obsessed with keeping her son pure that she discouraged him from sleeping 
with his wife. Some even whispered that she had an unnatural attachment to him, though that’s 
probably more medieval gossip than reliable   record. Still, it speaks to the way Blanch 
was viewed. Intense, commanding, and always just a bit unsettling. You don’t get to rule as a 
woman in the 13th century without people throwing   a little suspicion your way, especially if you’re 
doing it successfully. And Blanch was successful. She not only held France together during her son’s 
minority, but she later returned to Regency when   he left the crusade. For years, she governed 
with a stern hand and a sharp eye, navigating rebellions, famine, and papal politics with barely 
a stumble. But the toll on her family and possibly her children’s health remained an undercurrent. 
One scholarly debate that’s still alive today was Blanch herself subtly affected by the genetic 
tightroppe her family walked. While there’s no record of physical deformity or obvious illness, 
some letters suggest she suffered from extreme   migraines and recurring melancholia. that lovely 
medieval catch all that could mean depression, hormonal imbalance, or something passed along the 
family line like a well polished heirloom. There’s also a fascinating detail from her death in 1252. 
Reportedly, she collapsed on the way to a convent and lingered in pain for days, murmuring prayers 
and hallucinating visions of saints. Some modern readers interpret this as spiritual ecstasy. 
Others, less romantically, wonder if it was a stroke or hereditary neurological condition. 
Again, no definitive answers, just a woman’s final days shrouded in mystery, much like her 
life. Here’s a lesserknown fact. Blanch was one of the first French queens to actively sponsor 
universities. She supported the development of theology studies at the University of Paris and 
personally funded monastic libraries. So yeah, while she was wrangling rebellious nobles 
and managing her emotionally complicated son,   she was also quietly helping launch the European 
intellectual renaissance. No big deal. You can almost imagine her today ghosting through a 
candle lit library in Ruon, muttering Latin apherisms and glaring disapprovingly at anyone 
making noise. Not mad, not tragic, just tired, and probably still running things from beyond 
the grave. So, while Blanch of Castile isn’t   the most inbred woman on our list, she represents 
an early example of how medieval power marriages began to fold back in on themselves and how royal 
women burdened with bloodlines and expectations carved out their legacies. Anyway, sometimes with 
iron fists hidden beneath silken sleeves. Next, we’ll travel to Portugal where Elellanar of 
Portugal finds herself pulled into a family   dynamic so twisted that her groom shares not 
just her family name, but her uncle’s face. Hope you’re ready for that one. And now let’s take 
a soft step into the warm Iberian air of the 15th century. Where stone palaces glint beneath the 
Portuguese sun and royal carriages creek beneath the weight of more than just gold and silk. They 
carry dynastic expectations, ancient rivalries, and the kind of family ties that require both a 
wedding and a DNA test. Tonight’s central figure, Eleanor of Portugal. If you’re already cringing 
at the thought of an uncle becoming a husband, congratulations. you’re awake and paying 
attention because yes, that actually happened and it wasn’t even considered all that weird at 
the time. Elellanena was born in 1434 into the house of Avas, a branch of the Portuguese royal 
family known for its tangled roots and political ambitions. She was one of several children born to 
King Edward of Portugal and Elellaner of Araggon, which already made her a prize in the 
international marriage market. Her siblings   included future kings and queens, but Elellanena’s 
path would take her north into the chile reaches of the Holy Roman Empire, where her marriage 
was supposed to cement a powerful alliance.   What no one talked about at the wedding feast 
was how closely she and her groom were already relate. Her husband, Emperor Frederick III, was 
not only her cousin, but he was technically her uncle through marriage lines so convoluted they 
practically form a Celtic knot. But of course,   inbreeding among royals wasn’t just tolerated, 
it was the norm. Marrying a close relative wasn’t scandalous. It was strategic. If it kept the 
throne within the family and prevented rival claims, then so be it. The Pope would give a 
little nod of approval, issue a dispensation, and another cousinly kiss would seal the fate 
of another generation. Elellanena’s wedding to Frederick was awkward from the start. She 
traveled to Italy for the ceremony, which was   delayed several times because Frederick, over 
the cautious emperor, was reluctant to commit. He reportedly didn’t even meet her until the 
actual wedding day, and his first reaction was,   “She’s prettier than her portrait, so yay for low 
expectations.” The wedding finally went through in 1452, and Elellanena became Holy Roman Empress, 
one of the most powerful titles in Christrysendom. But power doesn’t guarantee happiness. 
Their marriage was strained. Elellanena,   raised in the more relaxed and artistically rich 
courts of Portugal, found Frederick’s court cold, rigid, and depressingly frugal. He was obsessed 
with bureaucracy and finances. She wanted music, color, and life. Letters from the time hint at 
her frustration. She reportedly once said that her husband would rather count coins than kiss his 
wife. Yikes. Meanwhile, Frederick found Ellanena too emotional, too passionate to house this for 
irony, too foreign. Still they did their dynastic duty and had five children, three of whom survived 
infancy. Among them was Maxmillian Befersus, who would go on to become Holy Roman Emperor 
and marry yet another cousin, solidifying the   Habsburg rise to power. But Elellanena, she 
struggled. Her health began to deteriorate, possibly from the strain of pregnancies, long cold 
winters, and the slow suffocation of life with a man who treated her more like an economic adviser 
than a wife. Now, let’s talk about the genetics. Elellanena and Frederick’s shared bloodline was 
already layered with intermarriage. Both had   ancestors from the Aragon and Beagandian houses 
and their union concentrated that blood further. The result, their son, Maxmillian inherited the 
family jaw, the early hints of the legendary Habsburg jaw that would come to symbolize 
centuries of royal inbreeding. But that’s   just the visible sign. What historians whisper 
about more quietly is the mental health issues, miscarriages, and the faint echo of autoimmune 
disorders that crop up again and again in the family line. A quirky side note, Helena is one of 
the few medieval empresses whose voice survives in her own hand. Some of her letters to her brother, 
King Alphonso V of Portugal, still exist. In them, she vents about court life, the isolation she 
feels, and how much she misses home. There’s something hauntingly modern about her complaints. 
She talks about not having anyone to confide in,   about feeling like an outsider even in her own 
family, and about the cold halls of the imperial court that seem to suck the life out of her. 
If there’s a ghost pacing through those stone   corridors at Growl or Vina Noad, it’s probably 
Elellanena, still homesick and misunderstood. Here’s where scholarly debate still flickers. Was 
Elellanena simply a mismatched wife trapped in a political alliance? Or was she experiencing 
the early toll of genetic accumulation? Her declining health has been attributed to attributed 
to everything from tuberculosis to depression, but some researchers suggest she may have inherited a 
form of pferia, a blood disorder linked to noble lineages and sometimes mistaken for madness or 
hysteria. There’s no conclusive evidence, just hints in her letters and descriptions from court 
chronicers about her pal, sensitivity to light, and frequent fits of melancholy. She died young, 
just 32 years old. Officially, it was illness, but most agree it was a long and painful slide into 
frailty, worsened by years of emotional neglect and probably some good old-fashioned medieval 
medical malpractice. Frederick didn’t even attend her funeral. He stayed behind, reportedly busy 
with court documents. That tells you everything, doesn’t it? And yet, Elellanena’s legacy looms 
large. Her son Maxmillian would go on to shape European history, expanding the Habsburg Empire 
and marrying his own relatives with relentless efficiency. Helena’s blood would flow through 
the veins of emperors and queens, carrying with it both the strength of her Iberian heritage 
and the weaknesses of a gene pool that had been   stirred far too little. What stands out most 
about Helena is the quiet sadness that threads through her life. She wasn’t mad like Joanna. She 
wasn’t ironwilled like Blanch. She was soft-edged, romantic, and ultimately too human for the cold 
machinery of imperial politics. But she played her part. She gave birth to the next dynasty. And that 
for a royal woman of her time was the highest and most unforgiving form of success. Next, we’ll meet 
Margaret of Austria, Elellanena’s granddaughter, and one of the sharpest political minds of 
her day. Raised in a family so genetically   compact that holiday dinners probably required 
a family tree cheat sheet just to figure out who to kiss on the cheek. Now, imagine this. You’re 
a young girl born into a labyrinth of castles, cousins, and kings. And before you’ve even 
lost your baby teeth, you’re already being   discussed like a valuable chess piece. That was 
Margaret of Austria. And yes, she’s technically the granddaughter of Elellanena of Portugal, 
but by this point, the Habsburg family line   has twisted itself into such tight knots that 
even the family dog might have qualified for a noble title. Margaret grew up in the very eye 
of this donastic storm, trained to smile curtsy, and marry strategically. But what makes her stand 
out in this parade of inbred nobility is that she didn’t just survive the system, she mastered 
it. Born in 1480 in Brussels, Margaret was the daughter of Maxmleon the first, the Holy Roman 
Emperor and son of, you guessed it, Frederick and Elellanena. Her mother, Mary of Burgundy, 
died young after falling off a horse, which   left Margaret motherless by age two. Right out of 
the cradle, she was seen not as a grieving child, but as a dynastic prize. Her father immediately 
betrothed her to the French doofant Charles who was barely older than her and would later become 
King Charles Lei. At the ripe old age of three, Margaret was shipped off to the French court to 
be raised as the future queen of France. As far   as political gambits go, it was classic Habsburg. 
Start young, lock in alliances early, and hope nobody dies in the meantime. But things didn’t go 
according to plan. When Charles reached marrying age, he ditched Margaret and instead married 
Anne of Britany, a major territorial win, but a total slap in the face to the girl who’d grown 
up in his palace. Margaret, still a teenager, was unceremoniously returned to her father, 
heartbroken and politically bruised. If she cried on the way home, no one wrote it down. But from 
this point on, she started building a different   kind of power. She was married off again, this 
time to John of Castellair to the Spanish throne. Yes, that same Spanish royal line that came 
from her own tangled ancestry. Once again, the jeans looped together like tangled Christmas 
lights. Margaret and John were cousins several times over, connected through both the Habsburg 
and Trestara lines. Their marriage was brief. Jon died within a year, probably from tuberculosis, 
though rumors of poison floated around because, well, medieval courts loved a little conspiracy 
with their mourning. Margaret, now widowed before age 20, might have been expected to fade into 
the background and quietly become a nun or   a melancholy daagger. But nope, not Margaret. 
She returned to the Habsburg court and slowly, steadily carved out a political identity so sharp 
it could slice through stained glass. She never remarried, instead dedicating herself to politics 
and governance, eventually becoming governor of the Netherlands twice. That’s right, a royal 
woman governing a powerful economic hub while maintaining diplomatic relations with France, 
Spain, and England. And she did it all while   wearing gowns so stiff with embroidery they could 
stand on their own. Now, let’s not forget the inbreeding elephant in the room. Margaret’s entire 
family was deep into cousin territory. Her father, Maximleon the First, had married his cousin. Her 
brother, Philip the Handsome, would marry Joanna of Castl, who was also their cousin. Margaret 
herself had married her cousin. The Habsburg family tree by this point resembled a Mobius strip 
and you can start to see the effects. Her brother Philip died young of fever and his son Charles V 
would inherit so much consolidated genetic baggage that his chin could be spotted from orbit. But 
Margaret, she didn’t seem to suffer physically from the family’s favored marital policies. 
She was sharp, healthy for most of her life,   and politically astute. Some historians point 
to her as a rare example of a Habsburg woman who defied the decline. Still, her life wasn’t 
untouched by the consequences. As guardian of her niece and nephew, Charles F and his siblings, 
she was intimately aware of the psychological and physical toll the family bloodlines were starting 
to take. One of her nieces, Elellanena of Austria, would go on to marry yet another cousin. Another, 
Catherine, would marry King John III of Portugal, her double first cousin. Margaret arranged many 
of these marriages herself, fully aware aware of the genetics involved, while also boxed 
in by political necessity. A quirky fact, Margaret had a pet monkey named Barb and was 
famously fond of her collection of books,   tapestries, and art. She was also an avid letter 
writer. Her correspondence with her cousin, the famed humanist Arasmus, reveals a woman of 
intelligence, wit, and occasional dry sarcasm. In one letter, she describes a courtier as having 
the charm of a leaky wine barrel, which frankly should be embroidered on a pillow. Scholars still 
debate just how powerful Margaret really was. Some say she was merely a figurehead, executing the 
plans of her male relatives. Others argue she was the puppet master, subtly influencing the 
direction of Habsburg, Europe, from behind the   Velvet Curtain. There’s evidence for both. What’s 
certain is the kings wrote to her for advice. Ambassadors reported to her and her policies 
kept the Netherlands relatively stable during   years of upheaval. Not bad for someone who’d been 
used like a porn in two failed marriages before her 20th birthday. Margaret died in 1530 at age 
50 from complications after stepping on a nail, proving that not even imperial savvy can save you 
from tetanus. But her death was deeply mourned. Even Arasmus wrote in grief saying that Europe 
had lost one of its finest minds. Not one of its finest women, mind you, its finest minds. 
High praise from a Renaissance intellectual. In the end, Margaret of Austra stands as a sharp 
contrast to so many of the tragic wilting flowers that populate royal family trees. She may have 
been born from the same inbredad tangle, but she bloomed on her own terms. She arranged the very 
marriages that would further twist her family’s genetic fabric. Yes, but not out of cruelty or 
blindness. She was playing the only game allowed to her, and she played it better than most. Next, 
we’ll head into England to meet one of Margaret’s future sisters-in-law by marriage, Catherine of 
Araggon, another princess of Castile, another victim of a cousin’s stacking, and the woman who 
would eventually face off with Henry VII in a   marital battle for the ages. You hear the clink 
of golden goblets, the rustle of silk skirts, the echo of Latin prayers drifting through a stone 
chapel lit by thin beams of morning light. You’re in England now, early 16th century, just before 
everything goes off the rails. And at the center of this poised, polished moment is a young woman 
with a serene smile and a bloodline more knotted than a sailor’s test. Catherine of Araggon. You 
probably know her as Henry VII’s first wife, the one he dumped for Anne Berlin, sparking his 
religious firestorm and beheading spree. But before all that drama, Catherine had already lived 
a life that reads like a dynastic instruction manual titled How to Marry Your Cousins and Lose 
Everything. Anyway, Katherine was born in 1485, the youngest daughter of Ferdinand Gil 
of Araggon and Isabella I of Castile, the same power couple we met earlier when Joanna 
the Mad was crying into her embroidery. Catherine was the afterthought baby born right around the 
time Spain was finishing up its reconquest and evicting the last Muslim rulers from Granada. 
So she entered the world at triumphant bloody moment. Her parents now the United Catholic 
Monarchs, their children purebred donastic gold. Now let’s take a peek at that family tree, 
shall we? Her parents were second cousins, part of the Trusttomara dynasty that had already 
been intermaring with each other and with various   branches of French, Portuguese, and Beagandian 
nobility. That meant Catherine had Habsburg blood on both sides, as well as Plantaginate 
blood through earlier generations. Her double cousin status wasn’t some weird exception. It 
was practically a feature. In fact, Catherine was prepackaged for royal marriage. Bilingual, 
pious, educated, and genetically engineered to match up with every major ruling house in Europe. 
At just 3 years old, she was promised to Arthur, Prince of Wales, son of Henry VIIIth of England. 
By age 15, she was shipped off to a cold tuda court with her dowy, her ladies in waiting, 
and more Spanish lace than an entire convent. The wedding happened in 1501. A grand ceremony 
that was equal parts diplomatic showcase and political insurance. Arthur was the future king 
and Catherine, his Spanish bride, was expected to sew Spain and England together at the hip. A 
few days after the wedding, they were reportedly sent to bed with enough ceremony to fill a novel. 
The court watched them climb into bed together, then left the couple alone to begin what everyone 
assumed would be a long and fertile partnership. And then Arthur died. 5 months into the marriage, 
he was gone, possibly from the sweating sickness, possibly tuberculosis. Suddenly, the grand plan 
unraveled. Catherine was left stranded in England, her dowy only partially paid, her future unclear, 
and her virginity under suspicious review. You see, whether or not she and Arthur had actually 
consumated their marriage would become the   hottest theological debate in Europe two decades 
later. But at the time, it was just humiliating. Still, the donastic wheels kept turning. Within a 
year, Henry VIIIth proposed a new plan. Catherine would marry Arthur’s younger brother, Henry, 
who would one day become that Henry. There was one little problem. Marrying your dead husband’s 
brother against church law. No big deal, though, because Catherine swore up and down the marriage 
was never consumated, and Pope Julius II granted a papal dispensation. The wedding wouldn’t 
happen until 1509 after Henry VIIIth died and young athletic golden boy Henry VIII ascended the 
throne. And for a while it seemed like everything was going to be fine. Catherine was Queen of 
England, adored by the people, fluent in Latin, devoted to religion and often more politically 
savvy than her husband. She even served as regent while Henry was off playing soldier in France and 
managed to pull off a stunning victory against   the Scots at the Battle of Flaen. But beneath 
the pearls and courtly dances, the dynasty’s foundation was already cracking. Catherine’s 
pregnancies were a tragedy in slow motion.   She was pregnant at least six times. Only one 
child, Mary, survived. The rest, boys and girls, were still born, died shortly after birth or 
miscarried. The pressure was immense, and everyone wanted a male heir. Henry, once smitten, grew 
bitter and paranoid. The court started whispering. Was the queen cursed? Was God punishing them for 
the technically incestuous marriage? And here’s where the genetics rear their wellocumented, 
scientifically recognized head. Catherine’s own maternal grandparents were both from the Trust 
line, meaning her parents were not just cousins. They were part of a lineage that had looped in 
on itself for generations. Some researchers today believe that the repeated infant deaths may have 
stemmed from a genetic incompatibility between   her and Henry. A hypothesis that involves what’s 
called keloim immunization. If true, it would mean Katherine carried a blood antigen that caused 
her body to attack fetal red blood cells after   the first successful pregnancy. A cruel twist 
of biology passed down from centuries of noble cousin matching. But back then, no one could name 
it. They just saw failure. and failure in a queen always ends badly. By 1525, Henry had fixated on 
Anne Berlin. Catherine was pushed aside, stripped of her titles and confined. She refused to agree 
to an analment, insisting she was Henry’s lawful wife and queen. This wasn’t just personal, it was 
spiritual. Catherine believed to the bitter end that her marriage had been holy, her role ordained 
by God, and her daughter Mary, the rightful heir. Her refusal sparked the English Reformation. 
Henry broke from the Catholic Church, dissolved the monasteries, and launched a religious war that 
would split England for generations. All because   one queen wouldn’t lie about a marriage he’d been 
forced into at 15. A quirky fact about Catherine, she was a total bookworm. Fluent in Latin and 
Spanish, she often translated religious texts and was a known patron of humanist scholars. Arasmus 
of Rotterdam. Yes, that Arasmus once praised her intellect, and when she was confined at Kimbleton 
Castle in her final years, she reportedly spent her days in prayer, embroidery, and letterw 
writing. Her last letter to Henry addressed   him not as a tyrant or betrayer, but as my most 
dear lord and husband, which, yeah, that’s either devotion on a saintly level or the final note in 
a lifetime of royal gaslighting. Scholars still argue whether Catherine’s miscarriages were purely 
bad luck or symptoms of deeper genetic issues. But what’s undeniable is how her life, like so many 
royal women, was shaped and ultimately shattered by a family tree too bent to stand straight. She 
was the product of dynasties that believed in the divine right of kings and the divine necessity of 
cousins. And in the end, all that purity of blood   couldn’t save her. Next, we’ll meet Isabella of 
Portugal, Catherine’s niece and the empress who married her own double first cousin, producing 
a son whose chin and destiny would both go down   in history. You find yourself now in a golden 
sunlit hall in Toledo, somewhere between the glow of power and sunborn in the long shadow of 
legacy. Tapestries rustle in a breeze that smells faintly of incense and dried roses. At the head of 
this hall stands a woman draped in regal silence. Isabella of Portugal. If Catherine of Araggon had 
the stubborn defiance of a queen wronged, Isabella has the heavy poise of one born knowing exactly 
what’s expected and exactly how it’s going to hurt. Because Isabella didn’t just marry a cousin, 
she married her double first cousin. That’s a genetic term. Yes. And a very real nightmare, 
especially when you’re carrying the weight of two dynasties on your spine and producing an heir, 
becomes the one job you’re not allowed to mess up. Let’s pull apart that relationship for a moment. 
Isabella’s father was King Manuel of Pierre Cit of Portugal. Her mother was Maria of Araggon, the 
sister of Catherine of Araggon. So Isabella was a product of both the Avis line of Portugal and the 
Trstar line of Spain. Two royal houses already deeply entangled through years of intermarriage. 
When she married Charles V, Holy Roman Emperor and King of Spain, the bloodline looped sealed tight. 
Charles wasn’t just her cousin once over. He was her cousin twice from both sides of the family. 
He could practically hear their chromosomes grown   when they exchanged vows. But in true imperial 
fashion, the marriage was pitched as a triumph. Charles V was the most powerful monarch in Europe 
at the time, ruling over not just Spain, but huge swathers of Italy, Germany, the Low Countries, 
and the Americas. And Isabella, she was the purest blood match available. Their wedding in 1526 was 
grand, even by Habsburg standards. dancing music, elaborate feasting, and political congratulations 
disguised as poetry. Historians have noted that Charles genuinely loved Isabella. In fact, he was 
unusually faithful by royal standards. He even missed her when he went off on his frequent 
imperial errands, which, let’s be honest,   is more than most kings of the period could say. 
Still, love doesn’t undo DNA. Isabella and Charles had seven children, but only three survived 
to adulthood. Among those was Philip II of Spain. Yes, the gloomy Catholic king who later 
married Mary Tuda and went on to make England very nervous. Philip would inherit not just his 
father’s empire but his mother’s deeply saturated royal blood. And as with so many dynastic 
lineages, it showed, but more on that soon. Isabella herself was described as intelligent, 
composed, and deeply pious. She was fluent in Latin and took her role as empress seriously. 
While Charles was away fighting Protestants or   reorganizing his vast empire, Isabella served 
as regent in Spain, overseeing trade, taxes, military provisioning, and all the other joys of 
early modern bureaucracy. Letters between her and Charles reveal an administrative partnership as 
much as a romantic one. She wrote about provincial uprisings, grain prices, and the latest news from 
the Americas with all the precision of a modern chief of staff. But her reign wasn’t all ledges 
and letters. Behind the polished court surface, Isabella was plagued by anxiety and health 
issues. Like many women in her family,   she suffered through multiple pregnancies, several 
of them ending in stillbirth. And though it’s not documented in clinical language, because this was 
the 16th century, and everything got filed under   melancholia, modern historians believe she showed 
signs of chronic depression, perhaps postpartum, or perhaps inherited from the same bloodlines 
that made her both a queen and a statistic.   There’s a particularly eerie moment preserved in 
court diaries. Isabella, pregnant with what would be her final child, fainted during a religious 
procession. It was a public event, and the crowd gasped as she collapsed, pale and unconscious, 
onto the stone steps of a cathedral. She never fully recovered. Less than a year later, in 1539, 
she died at the age of 36. The official cause was complications from childbirth. The vague term that 
could mean anything from hemorrhage to infection to perhaps her body just giving out after too 
much strain, too many children, too much duty, too little rest. Charles was devastated. He 
wore black for the rest of his life. Bummer. He commissioned portraits, sculptures, and even 
a grand tomb in her honor. But he didn’t remarry. For a man who ruled half the known world, that’s 
saying something. He later retired to a monastery and took up clockmaking, which feels very on 
brand for a man who’d spent his life trying to   keep a ticking empire from falling apart. Here’s 
the historical wild card. Isabella’s bloodline, intensely inbred, meticulously preserved, produced 
Philip II, who then went on to marry his own niece and later his own cousin. The loop didn’t just 
continue, it tightened. One scholar referred to Isabelle and Charles’s marriage as the turning 
point from strategy to surrender. From that moment on, the Habsburgs were no longer just into 
marrying to strengthen alliances. They were doing   it because there were hardly any outsiders left 
who matched their standards of royal purity. Now, here’s the quirky twist. Despite the increasingly 
fragile bodies coming out of this genetic funnel, the Hapsburgs kept winning. Empires expanded. Gold 
flowed from the Americas. Enemies were crushed. There’s a strange tension in Isabella’s story 
between this visible triumph and invisible   decline, between a court gilded with silver 
thread and a body breaking down from too much repetition in the gene code. Was Isabella aware 
of the danger? Probably not in the way we’d think about it today. Her letters mentioned 
illness, still births, headaches, but never   genetics. That wasn’t a concept yet. The idea that 
marrying your cousin might doom your children to physical or mental frailty wouldn’t enter common 
discourse until centuries later. And even then,   royals would ignore it. But the signs were there 
in the haunted eyes of her surviving son. In the funerals she attended for infants who never drew 
breath. In the silence that followed her own death as the Spanish court wrapped itself in black 
and the empire she helped hold together quietly   creaked under its own weight. Isabella of Portugal 
is often overshadowed by louder names. Catherine, Anne, Mary, even Charles. But her story is one of 
the clearest lenses through which you can view the cost of dynastic ambition. She was everything 
a queen was supposed to be. Noble, obedient, fertile, and ultimately gone too soon. Next, 
we shift focus north, where Margaret’s legacy continues in the Low Countries, and a Duchess 
named Maria Burgundy tries to escape the trap. But the family tree has other plans. The light shifts 
now, grows cooler, softer as we drift north from the sunscorched courts of Iberia to the lush, damp 
pastures of Burgundy, where silk banners flap in a colder breeze and the halls are more Dutch than 
Spanish, more Flemish than Castellian. You find yourself in the Beandian Netherlands, that rich 
glittering corner of Europe that always seemed to lie just outside the reach of stability. And 
in the middle of it all, wrapped in furs and   political anxiety, stands Marie of Burgundy. If 
you’re hoping for a moment of calm in our parade of inbred royalty, well, not tonight. Marie is 
another noble woman tangled in the Habsburg web. And though she tries to claw her way out, fate and 
family have other plans. Marie was born in 1457, the only child of Charles the Bold, Duke 
of Burgundy, and Isabella of Bourbon. Now, her mother was the daughter of a Bourban prince 
and a Valwa princess, meaning Marie’s family tree had already been bending in on itself like a drunk 
trying to tie a necktie. Charles the Bold wanted a son. Of course, he did. But when Marie arrived, he 
immediately began preparing her to rule. And not just symbolically. He raised her to read treaties, 
interpret military reports, and conduct court rituals with the weight of a sovereign. That was 
all well and good until he died suddenly in battle   at Nancy in 1477. leaving 19-year-old Marie 
as ruler of one of the richest territories in Europe and unmarried. Cue the political feeding 
frenzy. France always circling Burgundy like a hungry wolf move fast. King Louis the 11th wanted 
Marie to marry his son and take Burgundy with her into French hands. The Low Countries weren’t 
having it. They preferred the Hapsburgs. Yes, those charming overlords of cousin marriages 
and imperial ambition. So, the Burgundian nobles made their move. They offered Marie’s hand to 
Maxmillian of Austria, son of Emperor Frederick   III. And yes, if that name sounds familiar, it 
should. That’s the same Maxmillian who was the son of Elellanar of Portugal and Frederick III. 
Meaning, you guessed it, another round of cousin   knots just got added to the pile. Marie, to her 
credit, wasn’t all that thrilled about the idea. She’d been educated to rule, not just to serve. 
She reportedly delayed the marriage negotiations, insisting on favorable terms. And in a rare 
medieval flex, she also issued the great privilege, the document that gave significant 
power to the local provinces in exchange for   their support. That wasn’t just politics. It was 
a rebellion against the centralized royal control that her suitors, especially the French and 
Habsburgs, preferred. But in the end, the donastic machine won. She married Maxmillian in 1477. And 
with that marriage, the Habsburgs inherited the entire Beagandian inheritance, a prize that 
would define European politics for the next   century. Now, here’s the part where the gene pool 
starts bubbling ominously. Marie and Maxmleon were distant cousins, connected through generations 
of Valoir and Habsburg unions. Their children, therefore, were a perfect blend of French, 
Burgundian, Austrian, and Iberian royal blood,   none of which had ever spent much time outside 
the family circle. Their son, Philip the Hansom, would later marry Joanna of the Mad of Castile, 
which we’ve already covered in all its emotionally   volatile glory. So, yes, Maria of Burgundy is 
technically the great-grandmother of Charles V and one of the key contributors to the now 
infamous Habsburg Jaw, but Marie didn’t live long enough to see what her bloodline would 
become. She died in 1482, just 5 years after her wedding in a tragic horse riding accident. She 
was out hunting, a proper noble pastime. When her horse slipped on the muddy road and fell on top of 
her, her back was crushed. She lingered in agony for several days before dying at the age of 25. 
The court went into mourning. Maximleian wept, and Europe once again found itself with a power 
vacuum shaped like a young woman. Here’s the   quirky detail. Marie was buried in Bruge, and 
her tomb remains one of the most visited sites in the city. But during a renovation in the 20th 
century, archaeologists opened the tomb and found her remarkably wellpreserved skeleton, complete 
with a visible injury to the spine, exactly where   chronicers described her accident. It’s one of 
those eerie moments where legend and osteology meet under fluorescent lighting. So, what do 
scholars make of Marie’s role in the genetic arc   of Europe? Some view her as a pivotal figure, not 
just a dynastic match, but the critical hinge that swung the beandian legacy toward the Hapsburgs. 
Without Marie, there’s no Charles Fifth, no global empire, and possibly no grotesque accumulation 
of cousin-coded chromosomes. Others focus on her lost potential. As an educated, politically active 
young woman, she might have ruled Burgundy as an independent duchess. An alternative history where 
the Low Countries become their own powerhouse instead of yet another Habsburg annex. But history 
doesn’t deal in whatifs. Marie married the right man at the wrong time and died before she could 
shape her legacy. And that legacy ultimately became her descendants. Long-faced melancholic 
collic, sometimes brilliant, sometimes broken, but always bound to the throne by blood too thick 
to breathe freely. One final thought. Marie tried in her brief rule to decentralize power, to give 
voice to her people, and to resist the dynastic strangle hold of her time. But even her resistance 
became a tool of the empire. Her blood, her body, and her banner all ended up under Habsburg 
control. It’s the ultimate medieval irony.   The more she tried to escape the family knot, 
the tighter it pulled around her. Next, we head back into the heart of that knot and meet Anna of 
Austria. A woman who married her own nephew and somehow didn’t even make the top three weirdest 
Habsburg unions. Yeah, it’s about to get darker. The air thickens as we travel now to late 16th 
century Spain, a time when candles flickered against stone walls already haunted by portraits 
with too many identical faces. Welcome to the court of Philips at Second, where the inbreeding 
isn’t just an unfortunate footnote. It’s the main feature. And here, standing quietly in a velvet 
gown that probably weighed more than a grown dog, is Anna of Austria. She’s serene, devout, 
obedient, exactly what the Spanish court wanted in a queen. But behind that placid mask 
is a truth so twisted you could use it as a puzzle in a genetics class. Because Anna didn’t 
just marry her cousin, she married her uncle, her actual biological uncle. That’s right. She was 
17, who was her mother’s brother, and their shared genes could have won a family reunion bingo game 
in one turn. Hannah of Austria was born in 1549, daughter of Maxmillian II, Holy Roman Emperor and 
Maria of Spain. Maria in turn was the sister of Philip the making Anna both his niece and thanks 
to the Habsburg’s ongoing commitment to the family   circle already his cousin through multiple 
other lines. If you’re trying to keep track, just imagine their family tree as a plate of 
spaghetti where every noodle touches every other   noodle and someone spilled holy oil on it. At the 
time of their engagement, Philip II was already on his fourth marriage attempt. His first wife 
was Maria Manuela of Portugal, his double first cousin. Then came Mary I of England, also his 
cousin. Then Elizabeth of Valawa, again a cousin, and now his teenage niece, Anna. By this point, 
the Habsburgs had stopped bothering to look outside the family. They’d seen what happened 
when bloodlines got too mixed. Claims weakened, borders blurred, alliances frayed. Better to 
just keep it in the family, even if that family was starting to look like a set of nesting dolls 
with the same face. Their marriage took place in   1570. Philip was 43, Anna was 17. The age gap was 
considered completely normal. What wasn’t normal, even by 16th century standards, was how closely 
related they were. The Pope had to grant a special papal dispensation, one that raised more than a 
few eyebrows in Rome. But the political necessity overrode religious awkwardness. Philip needed a 
fertile wife to produce a male heir. His previous attempts hadn’t gone well, and Anna came with 
the best breeding credentials possible. Pure   Habsburg blood, extreme piety, and a womb 
unburdened by other dynastic alliances. So, how did this deeply incestuous union work out? 
surprisingly not terribly, at least in the short term. Hannah was reportedly kind, patient, and 
genuinely liked her husband. He in turn seems to have adored her in his own somber, tightly wound 
way. Unlike his previous marriages, this one   was relatively peaceful. No public arguments, no 
scandal. She played her role as queen perfectly, reserved in public, devoutly Catholic, endlessly 
maternal. She gave birth to five children in rapid succession, four of whom survived infancy, another 
Habsburg Miracle. One of those children was Philip the third of Spain, who would eventually 
succeed his father. But while Anna herself seemed to weather the biological risks of close in 
breeding better than some of her predecessors, the   genetic toll was quietly acrewing in her children. 
Philip III, her most famous son, grew up listless, indecisive, and deeply reliant on court favorites 
to govern. While not physically deformed like his own son would later be, many scholars note the 
intellectual and emotional decline that began   with this generation. He was smart enough to 
stay out of wars, but too passive to lead an empire. His reliance on court favorites like the 
Duke of Lurma led to widespread corruption and the slow decline of Spanish global influence. 
It was the beginning of a quiet unraveling, and Anna’s genes were part of the recipe. Here’s 
a fringe medical fact. Some researchers believe that the accumulation of recessive genes from 
repeated uncle niece marriages in the Habsburg   line contributed to something called mandibular 
progynathism aka the infamous Habsburg jaw. Hannah’s children showed early signs of this 
condition, but it would fully blossom in her   grandson Charles II whose jaw was so oversized 
he couldn’t chew food properly. That’s where we’re heading. For Hannah, she was still in the 
early stages of the Hapsburg decline. symptoms beginning to appear but not yet catastrophic. She 
died in 1580 just shy of her 31st birthday. The cause complications from child birth which given 
the rate at which he was expected to produce heirs is hardly surprising. Philip was devastated for 
a man so emotionally buttoned up his grief was palpable. He reportedly locked himself away 
for weeks, wore mourning clothes for the rest   of his life and never remarried. Some even say 
he kept her portrait beside him at all times, whispering prayers into the canvas. A tragically 
romantic detail or a sign that the man had finally realized what his dynasty had cost him. A quirky 
footnote. Anna was obsessed with relics and holy tokens. She collected saints bones, fragments 
of robes, and splinters of what was supposedly   the true cross. Her private chapel looked less 
like a royal sanctuary and more like a medieval medical museum. Was it a symptom of her devout 
upbringing? or maybe just a coping mechanism for a life that required daily denial of personal 
choice. Historians today still debate whether Anna knew the full scope of her genetic connection to 
Philip when she married him. It’s hard to believe she didn’t. But then again, in her world, marrying 
your uncle wasn’t scandalous. It was practical. It meant staying within the Habsburg brand, keeping 
outsiders out, and in ensuring the purity of the royal line. a purity that came at the cost of 
physical health, mental acuity, and for many women like Anna, their lives. She wasn’t flamboyant or 
rebellious or particularly outspoken. But Anna of Austria might just be the most quietly dangerous 
woman in this entire dynasty. Because from her womb came a generation that looked perfect on 
paper and hollow beneath the surface. Next up, we meet Hana of Austria, Hannah’s sister-in-law 
and one of the rare royal women who actually ruled in her own name. But even she couldn’t outrun the 
family’s shadow or its jeans. You wake up now in a Spanish court wrapped in somber elegance. Black 
silks, ivory beads, and incense soaked corridors where politics and piety dance in practiced 
silence. Here walks Hana of Austria. Tall, composed, and brilliant. She glides through the 
halls like someone raised not only among royalty, but as royalty. The kind of woman who bows to no 
one unless the optics require it. Unlike many of her predecessors, Hana isn’t just another dynastic 
porn shuffled into marriage and early death. She’s something rarer, a Habsburg woman trusted to 
rule. But don’t let that fool you into thinking she escaped the family curse. Her pedigree is as 
pure and as twisted as a pretzel dipped in holy water. Born in 1535, Wana was the daughter 
of Charles V and Isabella of Portugal. Yes, those two. The double first cousins from section 
8. So right from birth, her bloodline was tighter than a sealed tomb. But physically, Hana seemed 
to dodge the worst of the Habsburg deformities. No jawbone you could hang a curtain rod from, no 
reported limp, no debilitating disease. Instead, she inherited her father’s cool intellect 
and her mother’s quiet strength. That said, when both your parents are from the same set 
of grandparents twice over, you don’t exactly   get a clean slate. You get a loaded dice roll. Her 
childhood was cloaked in velvet and protocol. She was raised alongside her brother Philip Second and 
a rotating cast of aunts, tutors, and religious advisers who filled her head with languages, 
theology, and statecraft. She spoke Latin, French, and Castellian fluently by her teens and could 
hold her own in debates with bishops. Herasmus, if he’d still been alive, would have given her a 
slow clap. Now, here’s where her story veers off the usual track. At just 17, Wana was married to 
Prince Sha Manuel of Portugal, her first cousin. Not just your run-of-the-mill cousin, either. This 
was a solid intermarriage between two dynasties that had already been trading genes like medieval 
Pokémon cards. Juel’s health wasn’t great. He had that ghostly glow you only get from generations 
of not so genetic diversity. And sure enough, less than 2 years into the marriage, he died of 
what’s generally believed to be tuberculosis or some other inbred immunity failure. Hana was left 
a widow at 19. But wait, it gets better. She was also pregnant. The child, a boy, was born shortly 
after death and named Sebastian. He would later become king of Portugal. And if you’re imagining 
a strong virile monarch ready to lead his people   to glory, hold that thought. Sebastian was 
raised by priests, grew obsessed with crusading, and died in North Africa at 24, launching a 
succession crisis that would hand Portugal to Spain. But let’s not get ahead of ourselves. Back 
to Hana. After her husband’s death, the Portuguese court wanted her to stay and raise the new heir. 
Hana said, “Absolutely not.” She returned to Spain without her son, mind you, and resumed life at her 
brother’s court. And here’s where she pulls off the Habsburg equivalent of a power move. Philip 
II appointed her regent of Spain while he traveled to England to marry Queen Mary. That’s right. 
Huana of Austria, ruling Spain in her brother’s name. Not as a placeholder, not as a puppet. She 
governed for several years, overseeing finance, military matters, and diplomacy with the same 
authority a king would wield. And she did it with grace and very few public missteps. This was 
nearly unprecedented. Medieval and Renaissance courts were not exactly feminist havens. But Hana 
defied the norms. Even as she operated within a system built to exclude her, she knew how to 
speak its language, how to use its symbols, and when to stand absolutely still and let others 
collapse under their own weight. Of course,   no Habsburg woman gets a totally clean ride. After 
her regency, Hana retired to a convent in Madrid, not out of a sudden fit of piety, but by her own 
calculated choice. She became a nun. s, but also the convent’s founder and spiritual director. 
The convent of Las Descalas Reales, still standing today, was her kingdom in miniature, 
filled with art, relics, and silent power. She never remarried. Maybe she couldn’t. Maybe she 
didn’t want to. Scholars still debate whether her retreat to religious life was genuine devotion 
or a socially acceptable way to avoid becoming   another porn in the dynastic marriage game. Now, 
let’s talk about her son again. Sebastian grew up in Portugal under his grandmother’s care 
and a battalion of Jesuit tutors. Reports   from his youth suggest he was pious, stiff, and 
disturbingly single-minded. No marriage, no heirs, just endless sermons about war and purity. When 
he finally launched his disastrous campaign into Morocco, many suspected he was trying to live out 
the holy war fantasies fed to him in childhood. He died in battle. His body never recovered. Portugal 
spiraled into political chaos. The Spanish crown under Hana’s brother, Philip the Sexend, claimed 
it. Hana never saw her son again after she left Portugal. She never returned for him. Whether that 
haunts her, we’ll never know. Here’s your quirky historical footnote. Hana had a reputation for 
never raising her voice. In a court filled with loud men shouting about lineage and honor, Hana 
whispered and got her way. There’s an anecdote, possibly apocryphal, that during a tense council 
meeting, she silenced a room of bickering   ministers with a single raised eyebrow. That’s 
the kind of queen energy we can all aspire to. So, what’s the scholarly debate around Hana? 
Some argue she was the last clean Habsburg, a woman who somehow upvoided the worst physical 
and mental effects of inbreeding. Others think her health was the exception that proved the rule, 
a statistical blip in an otherwise steady decline. A few point to her decision to separate from her 
child and say she was cold, detached. Others see it as strategic genius, avoiding Portuguese 
court politics and securing her own power base. What’s certain is that Hana of Austria was 
one of the most capable women of her dynasty, possibly of her entire century. But even she 
couldn’t stop what was coming. Her genes, passed down through Sebastian, would play their 
part in ending Portugal’s independence. and the careful dynastic legacy she helped maintain. It 
would become the very thing that unraveled it all. Next up, we enter the Spanish Netherlands 
to meet Isabella Claraara Eugenia, the Habsburg princess who ruled with clarity and charisma and 
still carried the same tightly wound DNA spiral in every cell of her being. You find yourself 
now in the echoing corridors of a palace in the Spanish Netherlands, where the scent of beeswax, 
incense, and northern chill lingers in the stone. The tapestries are thick, the windows tall 
and solemn, and in the center of it all is a   woman dressed in black velvet, her hair tucked 
beneath a lace veil, her face composed like a carved cameo. This is Isabella Claraara Eugenia, 
daughter of Philip and Anna of Austria, product of uncle niece marriage, great granddaughter 
of double first cousins and one of the last   truly functional members of a dynasty straining 
under the weight of its own blood. Born in 1566, Isabella was genetically speaking already a 
miracle for being relatively healthy. Her parents, as you’ll recall, were so closely related that 
they probably shared more DNA than any married   couple should, even by medieval standards. And 
yet, here came Isabella, intelligent, steady, and eerily competent. She was raised in the 
heart of the Spanish court, fluent in Latin, French, and Italian. By the time most children 
were still struggling with prayers, her education was serious. Rhetoric, theology, diplomacy, she 
wasn’t being trained to be a consort. She was being trained to rule. At first, her future 
seemed to rest on the marital merrygoround. Several possible suitors were dangled, including 
no less than the aging widowerower King James V   6th of Scotland and briefly hilariously, Emperor 
Rudolph II, who was also her cousin and arguably already unraveling mentally, and the proposals 
floated. But her father, Philip II, kept stalling. He was deeply attached to Isabella, and there are 
strong hints that he simply couldn’t bear to give   her away. She remained unmarried until she was 
over 30, which in royal terms was practically a nun’s age. It wasn’t until Philip needed 
to stabilize the fracturing Netherlands that   he made his move. In 1598, Philip did something 
radical. He granted Isabella and her new husband, Archduke Albert of Austria, joint sovereignty over 
the Spanish Netherlands. That’s right. He gave her an actual throne. Not a decorative title, not a 
temporary regency. real power with real autonomy. The catch, Helbert was also her cousin, of course, 
and their marriage was arranged more for political   optics than romance. But as royal marriages go, 
theirs was weirdly successful. They shared a calm respect and a common goal. Bring peace to a 
region shredded by decades of Protestant rebellion and war. Isabella arrived in the Low Countries 
like a small royal storm cloud. dressed in black, flanked by advisers, and carrying the quiet 
authority of someone who had spent a lifetime   watching her father crush heretics and govern an 
empire. But she also brought something surprising, pragmatism. While Albert led the armies, Isabella 
worked the court. She restored cities, mediated religious tension, and charmed the nobility into 
cautious loyalty. The region was still a mess, but she managed to hold the center. And she 
wasn’t just a ruler in name. Contemporary letters   describe her as meticulous, detail obsessed, and 
deeply engaged in state matters. She would rise before dawn, attend mass, and then spur events 
the rest of the day dictating correspondence,   reviewing finances, and receiving ambassadors. 
One account describes her personally correcting a shipment of wool tariffs, while a priest nervously 
tried to get her to stop working and pray. Later, she reportedly said, “The flock must be fed.” 
Despite all this, Isabella never had children. Whether by choice or misfortune is unclear, 
some speculate that Albear, her cousin husband, may have been infertile due to their mutual family 
in breeding. Others suggest a miscarriage or two, hidden by court silence. What’s notable is that 
neither seemed too concerned with producing an   heir. They had each other and they had work to 
do. It’s oddly refreshing. Two Habsburgs in a functioning relationship that wasn’t built solely 
around utrine expectations. that the curse of the   dynasty always lingers. After Albert died in 1621, 
Isabella took religious vows and officially became a nun. But let’s be honest, she was a nun in the 
same way a CEO might become emmeritus. She kept her title, her influence, and her schedule. She 
just wore more black and talked more about God. In many ways, her post widowhood rule was even 
more effective. She held the Netherlands together through factional sniping, external pressure, and 
the slow encroachment of war. Here’s the quirky detail. Isabella loved theater, not just in a 
royal patron kind of way. She personally reviewed scripts, attended rehearsals, and even acted in 
morality plays when she was younger. One courtier recorded watching her perform a scene as the 
Virgin Mary, noting that she delivered her lines   with such precision it seemed more sermon than 
drama. Honestly, it sounds like she could have had a solid career in the arts if she hadn’t been 
born into one of Europe’s most overbred families. Now the scholarly debate. Was Isabella Claraara 
Eugenia the last competent Habsburg? Some historians argue yes. She’s seen as the final 
bright flicker before the dynasty descended into mental instability and physical deformity. 
Others argue she benefited from circumstance. She ruled a smaller territory during a relative lull 
in European chaos with a husband who shared power. Either way, she made an impression. While other 
Habsburg women were remembered for their deaths, their wombs or their madness, Isabella was 
remembered for her leadership. She died in 1633 at the age of 66. A shockingly long life for 
a Habsburg woman. Her funeral in Brussels was a major event attended by nobles, priests, artists, 
and commoners alike. She left behind no children, but a political legacy strong enough to be 
remembered centuries later. And for once,   that legacy wasn’t about how crooked her jaw was 
or how many cousins she married. Isabella Claraara Eugenia is proof that even in the middle of a 
genetic swamp, a single candle can burn steadily. She wasn’t loud, she wasn’t dramatic, but she 
ruled, she led, and she managed to carry the unbearable weight of Hapsburg inheritance with 
something that looked a lot like grace. Next, we travel to Versailles, where another branch 
of the family tree unravels in powdered wigs and   satin corsets. Starting with Maria Theresa of 
Spain, whose bourbon cousins were waiting with open arms and open marriage licenses. Let the echo 
of cobblestone horses and rustling satin lead you now into the golden corridors of Versailles, 
where mirrors stretch endlessly and the smell of rose water clings to every breath. Here we 
find Maria Teresa of Spain standing beneath a ceiling painted with gods she probably no longer 
believed in. She’s surrounded by chandeliers, gilded moldings, and a caught more obsessed 
with appearance than any in Europe’s long gaudy   history. But Maria Terza is not just another queen 
in a corset. She’s the living product of centuries of Habsburg intermarriage, carefully wrapped in 
tapeta and shipped north to become the wife of King Louis the 14th of France who also happens to 
be her double cousin. Born in 1638, Maria Theresa was the daughter of King Philip IVth of Spain and 
Elizabeth of France and already that’s a red flag. Her parents were first cousins, her grandparents 
were first cousins and her great-grandparents, you guessed it, also cousins. At this point, 
the Habsburg family wasn’t just inbred. They were aggressively recycling their gene pool 
like a medieval eco initiative gone horribly   wrong. So when Maria Theresa entered the world, 
her destiny was already shackled to the idea of preserving this legacy, no matter the cost. She 
grew up in the rigid sorrowing court of Spain, surrounded by Catholic somnity, black clothing, 
and enough incense to fog up every memory. Her education was strictly religious, heavy on saints, 
light on strategy. She was taught to be obedient, chasteed, and silent with the occasional music 
lesson thrown in to soften the edges. And then came the war of the Spanish succession, followed 
by peace negotiations. France and Spain needed to seal the deal with a marriage. The Maria Terraza, 
only 20, untested and thoroughly Habsburg, was offered as the gift. Louis the 14th the sun king 
was everything her core was not flashy confident secular in a dangerous way and drenched in power. 
He reportedly took one look at Maria Theresa and said she is the infanta of Spain which was 
either a compliment or a gentle acknowledgement that her reputation preceded her like a politely 
coughing ghost. Their marriage was arranged with urgency. France wanted peace. Spain wanted 
dignity. The wedding took place in 1660 on the border between their kingdoms and it included 
one of the most famous gestures in diplomatic   history. Louis met Maria Theresa on a small island 
in the middle of a river, neutral territory, and took her hand with a smile that masked 20 layers 
of political calculation. From the start, it was a mismatch. Maria Theresa was gentle, sheltered, and 
painfully pious. Louisie was worldly, calculating, and frankly busy chasing his mistress. He had a 
string of lovers before and after the wedding, and his court was a dizzying place full 
of intrigue, coded glances, and powdered   whispers. Maria Theresa wasn’t built for this. 
She tried, though. She smiled when required, bore Louis six children, though only one survived, 
and tried to navigate the court of Vessire without falling apart. But behind her jeweled eyes was a 
woman slowly unraveling from the inside out. Her Habsburg heritage wasn’t just a footnote, it was 
visible. Portraits show her with the soft jawline and slightly receding chin that marks her as 
royal stock from the Spanish side. She was small, often unwell, and prone to what doctors at the 
time politely called nervous spells, fainting, headaches, periods of withdrawn silence that 
lasted for days. Today, many suspect she suffered from chronic migraines, likely aggravated by the 
inbreeding and the constant stress of being an outsider in one of Europe’s most judgmental 
courts. And let’s not ignore the worst part, the children. Maria Theresa had six, but only 
one, the Doofan Louie, lived past childhood. The rest died of illness, often within months 
or even days of birth. The Bourbon line, though more genetically diverse than the Spanish 
Habsburgs, still bore the weight of that mingled   blood. The child losses devastated her, though she 
rarely showed it in public. Lewis, in contrast, moved on with the emotional elasticity of a man 
whose kingdom was always his first love. A quirky footnote, Maria Theresa had a fierce love for 
chocolate. Spain had introduced it to Europe, and she brought her habit with her to France. 
She reportedly drank thick, hot chocolate every morning, often seasoned with cinnamon and vanilla, 
though some blamed her frequent migraines on it. You can imagine her sitting in her velvet 
chambers, sipping from a porcelain cup,   trying not to cry while court ladies whispered 
about the king’s latest mistress just down the hall. The scholarly debate around Maria Theresa 
is more psychological than political. Was she simply too weak for the French court? Or was 
she a woman broken by years of silent trauma, cultural alienation, and the pressure to produce 
heirs when her body, burdened by generations of cousin pairing, was no longer capable. Historians 
argue over whether she was complicit in her own marginalization or merely surviving in a system 
that never gave her a chance. What’s certain is that Maria Theresa never fully integrated. 
She remained to the end the Spanish queen. Louie respected her position but not her 
person. When she died in 1683, reportedly from complications of an absessed arm, Louie 
declared, “This is the first time she has caused me pain.” Which, wow, that’s either devastating 
or just the crulest eulogy ever delivered in a silk lined hallway. But in true royal fashion, her 
legacy outlived her body. Her son, the Grandern, would carry forward the Bourbon line. And 
through a twisted game of political dominoes, Maria Theresa’s descendants would eventually sit 
on the Spanish throne, uniting the Bourbon and Habsburg bloodlines once more, because apparently 
Europe hadn’t had quite enough of that yet. So, here lies Maria Theresa of Spain, a queen in 
France, a stranger in her own life, a woman whose body became the shaky bridge between two empires, 
and whose silence screamed across centuries. Her death marked a turning point. Vessel would become 
even more theatrical, Spain even more fragile, and the dynasty even more doomed. Next, we tiptoe 
back into France, where her daughter-in-law, Elizabeth of Valois, married into the same 
bloodline from the other side, bringing a new   French twist to this increasingly inescapable loop 
of royalty, religion, and family resemblance. Now, we step back slightly in time, but not out of the 
genetic maze, as we move toward a figure who seems at first glance like a breath of fresh air in an 
otherwise stagnant bloodline. Elizabeth of Valawa, daughter of France, Queen of Spain, and yet 
another woman whose royal marriage was less about   romance and more about patching together crumbling 
dynasties with the human equivalent of genetic duct tape. She walked into Philip the second 
Spanish court with a flush of youthful beauty and a soft Parisian grace only to find herself trapped 
inside one of the most brittle inbredad bloodlines Europeam had to offer and surprise she was 
marrying her cousin again. Born in 1545, Elizabeth was the eldest daughter of King Henry the France 
and Katherine de Medici, a woman infamous in her own right for political manipulation, questionable 
poisons, and an unfortunate nose for disaster. But Elizabeth was her golden child, intelligent, 
well-mannered, fluent in Spanish, and painted in a flattering light from an early age. Her destiny, 
like that of all princesses in this strange, glittering game, was decided not by passional 
choice, but by treaties and territorial anxieties. Specifically, the treaty of Kato Comraes, which 
ended a long series of wars between France and Spain, sealed her fate. The treaty required a 
marriage to cement the peace. And Elizabeth, just 13 years old, was handed over to King 
Philip II of Spain. You may remember him. He’s the guy who married his niece, Anna of Austria 
later on. But Elizabeth was wife number three,   the one wed to him while he was still only 32 and 
still actively collecting cousins. At the time of their marriage in 1559, Elizabeth was 14. And the 
age gap, while not unheard of, was steep even by royal standards. More than that, the difference in 
personality was even steeper. Philip was reserved, austere and brooding, raised in the shadow 
of his Hapsburg heritage and the religious   obligation. Elizabeth, by contrast, had grown up 
in the vibrant, almost chaotic court of France, surrounded by artists, jesters, and that walking 
paradox of a mother, Catherine de Medici. She came to Spain full of life, curious about her new 
world. Spain, however, was not interested in being charmed. Life at the Spanish Corps was governed 
by somnity. Black garments, endless protocol, long masses, silences of virtue. Elizabeth found 
it stifling. And Philip found her youthful energy both fascinating and mildly inconvenient. But to 
his credit, he came to genuinely care for her. She was his political bride, yes, but he grew attached 
to her delicate intelligence and quiet strength. Their relationship, unlike many in this dynasty, 
bloomed gently into mutual affection. Still, the expectations were enormous. Elizabeth was 
supposed to provide a male heir, something the Spanish crown was always desperate for, especially 
given the high mortality rate of royal infants and   the increasingly fragile genetic lottery. Over the 
next few years, she endured several pregnancies. And here’s where history gets hazy. Some say she 
miscarried repeatedly. Others report she had two daughters and then a series of tragic losses, 
but all agree that her final pregnancy in 1568 ended in her death at just 23 years old, likely 
from a ruptured uterus. Yes, 23. It’s a brutal pattern now. Teenage brides, cousin marriages, a 
few fleeting moments of peace, and then a quiet death in childbirth while the court whispers 
about divine punishment or inherited curses. A   quirky fact. Elizabeth was a voracious reader and 
kept a personal library in her Spanish chambers. She insisted that her books be in both French and 
Spanish, which was considered mildly rebellious   at the time. One court lady wrote that the 
queen spent more time with pages than with pearls. And while that was probably intended as 
a slate, it now reads like a badge of honor. Now, let’s pause and run the genetics. Elizabeth’s 
father, Henry VII, came from the Valawir line, which had already begun intermingling with the 
Habsburgs through various cousins and strategic   alliances. Her mother, Katherine Demedi, was 
from the Medi family of Florence, a line not particularly known for inbreeding, but heavy on 
heart disease and toxic ambition. When Elizabeth married Philip theund, she added a burst of French 
DNA to the Spanish court, but not enough to dilute the heavy Habsburg stock. Their daughters Isabella 
Clar Eugenia and Catalina Michaela would carry these combined lines forward. Isabella especially 
whom we just met in the last section. What do scholars argue about when it comes to Elizabeth? 
Some see her as a mere figurehead, the victim of early death and tragic expectations. Others see 
her as a quietly subversive figure, someone who brought French flare and feminine diplomacy into a 
court that needed both. She was reportedly popular with the Spanish people, though she never wielded 
formal power. Still, in a place where queens were expected to be silent wombs, Elizabeth’s gentle 
intellect made more of a mark than many noticed at the time. And yet, for all her grace, she 
left behind the same painful legacy as the   rest. The royal lineage more focused on purity 
than health, more devoted to inheritance than vitality. Her children were raised with the same 
rigid expectations, the same constant pressure to marry within the family and the same blind trust 
that God would sort out the chromosomes. Spoiler, he did not. The irony, Elizabeth was actually 
first betrothed to Don Carlos, Philip’s unstable son from an earlier marriage. But that plan 
was nixed when everyone realized Carlos was, let’s say, unwell. violently paranoid, erratic, 
and ultimately imprisoned by his own father. So, Elizabeth got the father instead of the son, 
dodging one nightmare, but stepping into another slow unraveling. So, here lies Elizabeth of Valir, 
too young to fight, too smart to be forgotten, and too entangled in a genetic and political web to 
ever escape. a queen who brought color to a court painted only in gray and who in the end became 
another soft voice casualty of a dynasty that prized bloodlines over lives. Next, we’ll journey 
to a lesserk known figure, Barbara of Austria, a woman who unlike most of her relatives tried 
to steer her own ship even as the tide of family expectations threatened to pull her under. Now we 
drift quietly eastward, away from the golden glare of Versailles and the incense drenched gloom of 
Spain, and find ourselves in central Europe, where the courts are colder, the politics more tangled, 
and the family tree is just as knotted. Tonight’s chapter belongs to Barbara of Austria, a woman 
most people have never heard of, and yet she ticks every box in the Habsburg dynasty’s long-running 
checklist. noble birth, cousin to marriage, strategic deployment, and a life spent smiling 
through expectations she never really asked for. But Barbara is the different kind of Habsburg, 
subtler, slayer, and quietly rebellious in the ways that mattered. Born in 1539, Barbara was the 
daughter of Ferdinand Fest, Holy Roman Emperor, and Anna of Bohemia and Hungary. Her parents were, 
say it with me now, cousins. And her bloodline was as royal as they come, dense with titles, and 
thick with all the usual genetic baggage, nervous ailments, narrow jaws, and a family history 
of illnesses that no one in the court dared to   diagnose honestly. Still, Barbara came into the 
world with advantages. She was raised in Vienna in a court buzzing with scholars, musicians, 
and diplomats. She spoke multiple languages by adolescence was devout in that uniquely Habsburg 
Catholic way and according to at least one ambassador had eyes that knew them things. By the 
time she reached marriageable age, which surprise was somewhere around 14, Barbara was being 
quietly shopped around to various relatives and   allied royals. She was eventually married off to 
Alfonso II deste nobleman from one of Italy’s most prestigious houses but also yes a relative. Their 
union was arranged to strengthen ties between the Holy Roman Empire and northern Italy but also to 
keep the Habsburg blood flowing through powerful veins. Alfonso was the son of Erin and Reneea 
France, meaning his ancestry included French, Italian, and through the usual sideways marriages, 
Hapsburg connections. So, not immediate cousins, but the kind where if you traced it back three 
generations, you’d find a shared great-grandfather   hiding in a jeweled tomb somewhere. The marriage 
took place in 1565, and from the outside, it looked like a success. Barbara arrived in 
Ferrara with a retinue of ladies, priests, and enough embroidery to wrap the Alps. She embraced 
her duties with poise, patron of the arts, religious benefactor, duchess with a heart of 
gold, or at least gold leaf. But underneath that polished surface, Barbara was quietly carving out 
a space for herself. Unlike many of her inbredad contemporaries, she wasn’t content to just fade 
behind her husband’s shoulder. She refused to be an ornament. She demanded political briefings, 
managed palace staff with ruthless efficiency, and involved herself in diplomatic correspondence. 
One Venetian ambassador even called her the whisper behind the throne. And here’s the thing, 
Barbara was smarter than most of the men around her. She knew exactly what the game was, and 
she played it with velvet gloves and a steel   needle hidden beneath. When her husband began 
favoring courtiers who opposed Habsburg interests, Barbara moved quickly, replacing advisers, writing 
to her father, and making sure everyone understood   that the duchy of Ferrar was still married to the 
empire in every sense. But even Barbara couldn’t escape the Habsburg pattern of suffering in 
silence. She had health problems from the start,   though no one could say exactly what they were. 
Chronic fatigue, mysterious stomach pains, fainting spells. Her physicians called it a 
nervous weakness. Today, some historians suspect she may have had early signs of an autoimmune 
disorder or a neurological condition, both of which have been linked to inbreeding and appear 
repeatedly in Habsburg medical records. Others suggest she suffered from a chronic infection, 
perhaps tuberculosis, which was making the rounds in nearly every royal court at the time. And of 
course, there were the children, or rather the lack of them. Barbara never had a surviving heir. 
She reportedly had several miscarriages and her inability to produce a son was a constant source 
of quiet court gossip. As always though, the blame settled squarely on the woman. Even though Alfonso 
was widely rumored to have his own health issues, including a possible congenital defect that 
may have rendered him sterile. The irony,   in a marriage arranged for genetic power, the 
gene simply refused to cooperate. Here’s a quirky detail to tuck under your pillow. Barbara had a 
passion for astrology. In an age when science and superstition still dined at the same table, she 
kept a private astrologer who charted her days,   her moods, and her prayers. She reportedly 
delayed diplomatic meetings if her stars looked unfavorable and once refused to sign a treaty on 
a Tuesday because she had a feeling in her chest. Her brother, Maximleian, himself no stranger to 
odd habits, thought it charming. Her husband, not so much. Despite their growing distance, Barbara 
remained duchess in all the right ways. She funded convents, commissioned alterpieces, and kept the 
court of Ferrara humming. But her health continued to decline. By 1572, she was bedridden for 
weeks at a time. In 1572, at just 32 years old, she died, quietly surrounded by the monks, with 
incense burning and bells tolling the same tired song that had followed generations of Habsburg 
women before her. Alonso, in a rare public show of emotion, had a grand tomb constructed for her in 
the church of Corpus Dominara. But within months, he was remarried. This time to another noble woman 
from a politically advantageous house. Barbara was mourned, then filed away like so many Habsburg 
women, used, revered, and promptly forgotten. So, what do historians make of her? Some see Barbara 
as a minor figure, the duchess who never made   waves. Others, those who read between the lines, 
see a woman who understood the game and played it better than most. She wielded influence quietly, 
took control where she could, and managed to hold on to her dignity in a system designed to 
erase it. And yes, she died young, childless, and under the shadow of inbreeding. But she also 
left behind a court more stable than it had been   when she arrived, and her legacy of competence 
wrapped in silence. Barbara of Austria reminds us that not every royal woman screamed her way 
through history. Some whispered, some maneuvered, and some, like her, left fingerprints only 
visible if you know where to look. Next,   we return to Sicily, where constants of Aragam 
shows us that tangled bloodlines were already in fashion long before the Habsburgs made it their 
whole personality. Now, the air thickens again, not with incense or velvet, but with the dry, 
citrus, salted breeze of medieval Sicily. We’re going further back this time to the 13th 
century where Europe is still split into papal   loyalties and waring kingdoms. And the word 
dynasty means more than just who gets which throne. It means who owns the blood that flows 
between them. Here in Polmo with its jumble of Norman towers and Moorish gardens, we find 
Constance of Araggon, a queen whose life was less about being inbred than about being born into a 
family already spiraling through centuries of it. She’s a sort of prequel to everything we’ve seen. 
A woman who inherits the prototype for the same tangled dynastic ambitions that would later define 
the Habsburgs, the Capesians, and everyone else who couldn’t keep their rings off their cousin’s 
fingers. Constance was born in 1179 to Alonso II of Araggon and Sancha of Castile. And yes, her 
parents were cousins. No surprise there. In fact, both the House of Aragon and the Castellian crown 
had been intermaring for generations already. Long before the Habsburgs turned it into an art 
form, the Iberian royals were blending their   family lines into such a smooth puree of shared 
ancestry. The historians still struggle to map it without a whiteboard and several pots of coffee. 
Constance then entered the world with a bloodline already folding in on itself. She was royal, she 
was valuable, and she was destined to be traded like an extremely fancy political baseball card. 
By the time she was in her mid- teens, her future was sealed. She would marry Frederick Ze, heir to 
the kingdom of Sicily and the Holy Roman Empire. Frederick wasn’t just a powerful match. He was a 
complicated one. His mother, Constance of Sicily, yes, another Constance tried to keep up and died 
shortly after his birth. And his father, Emperor Henry V 6th, had left him under the protection 
of the Pope. But as with all royal matches, the politics behind it were more important than 
the people involved. Marrying Aragon into Sicily, that was strategy. It would give the Araggones a 
foothold in Italy. And the Hoen Stafen dynasty, the German royal line, would get a little 
infusion of Spanish prestige. Their marriage took place in 1209, and Constance was crowned 
queen of Sicily shortly after. She was about 30, relatively old for a first-time royal bride, 
but that gave her an unusual advantage. She wasn’t a teenage porn. She was an adult woman 
with education, political awareness, and some understanding of the game she was now playing. 
Frederick, meanwhile, was young, brilliant, and already deeply suspicious of everyone. And with 
good reason. His reign would be a non-stop chess match between the pope, the German princes, the 
rebellious Sicilian nobility and his own family members. Constance, for her part, kept her head 
low and her presence steady. She wasn’t flashy, but she was undeniably central. Now, here’s 
the genetic side note. The Ho and Stalphins, like the Araggones, had already been marrying 
within the same handful of noble families for   generations. That means Constance and Frederick, 
though from different countries, shared at least a few ancestors within three or four generations, 
making their children yet another link in the   slow tightening of Europe’s noble bloodline, 
noose. Their son, Henry VIIIth of Germany, would eventually rebel against his father, suffer from 
periods of depression and erratic behavior, and   die in prison, possibly by suicide. Is that nature 
or nurture? Well, the debate still rages. Some argue that Henry inherited his father’s paranoia 
and his mother’s melancholy, both of which may have been exacerbated by inherited traits passed 
through generations of intermarriage. But back to Constance, she wasn’t just a bystander in all 
this. During Frederick’s frequent absences, either fighting crusades, dodging paplex communications, 
or playing philosopher king in his court at Polmo, Constance served as regent of Sicily. She issued 
decrees, collected taxes, and oversaw court disputes. In other words, she ruled quietly, 
efficiently, and with a political savvy that suggests she knew exactly how thin the line was 
between queen and scapegoat. And to her credit, she managed to keep Sicily relatively stable 
in a time when stability was about as common   as indoor plumbing. A quirky detail, Constance 
reportedly had a deep interest in astronomy and was known to attend public celestial lectures 
in Polmo. This was during the court’s brief intellectual renaissance. Frederick was into 
Greek philosophy, Islamic medicine and astrology, and Constance seems to have soaked up the culture. 
One chronicler mentions her spending long evenings on palace terraces, studying the stars while 
court musicians played softly nearby. It paints a peaceful picture, though one suspects it was more 
escapism than leisure. But like most royal women of her era, Constance’s health became an issue 
after multiple pregnancies and years of stress. There’s little detailed medical record because 
of course there isn’t. But letters from the time   suggest she suffered from a wasting of the body 
in her later years. Today we might call it chronic fatigue or maybe a slow degenerative disease. Or 
maybe it was just the natural result of carrying centuries of compound. Compounded cousin DNA 
through war, exile, and court drama. She died in 1222, just 3 years after being crowned empress 
of the Holy Roman Empire. Frederick would go on to remarry several times in fact and continue the 
family’s long tradition of strategic inbreeding. But constants she faded into historical footnotes 
remembered mostly as the quiet queen who kept Sicily on track while her husband played Emperor 
Sant across Europe. Scholars today argue about her significance. Was she merely a placeholder, 
another Habsburg adjacent woman who did her job and died quietly? or was she the steadying force 
behind one of the most chaotic reigns in medieval history? The evidence is dense, but what survives 
suggests she had more influence than she’s usually credited with, especially in a world where royal 
women were expected to birth heirs, say prayers, and not much else. One thing’s clear, the DNA 
she carried and passed on would continue to ripple through European history. Her descendants 
would include not just emperors but eventually the very same Hapsburgs who would marry themselves 
into facial collapse. So in a way constants of Aragon is less a character than a cornerstone. 
The beginning of the blueprint proof that even in the early days the ruling houses of Europe were 
already writing a love letter to genetic roulette. Next, we’ll shift our gaze to England’s side 
of the tapestry and meet Margaret of York,   who didn’t bring inbred blood to the table so much 
as she married into the eye of the Habsburg storm, and watch the family gene pool start to boil. Now 
we cross the channel, slipping past white cliffs, and the damp English air to find ourselves in 
a world that feels oddly familiar. York roses, velvet cloaks, whispers, and cathedral isles. 
But instead of entering the fray of inbreeding from the birth side, we’re stepping into it 
from the marital edge. Meet Margaret of York. She isn’t inbred herself, not particularly, at 
least not by the dizzing standards we’ve been   charting. But she married right into the core 
of the Habsburg machine. And what she witnessed from inside those glittering her red tree hallways 
tells us just as much about the dangers of royal bloodlines as any genealogical chart ever 
could. Born in 1446 to Richard Plantaginet, Duke of York and Cesley Neville, Margaret grew 
up amid the violent highs and lows of the Wars of the Roses. Her family was stacked with in 
English royalty, but her childhood was far from peaceful. Her father was killed in battle. Her 
brothers Edward and Richard would become kings, one triumphantly, one briefly, and tragically, and 
the Yorkist faction to which she belonged would see itself rise, fall, and rise again. Margaret 
was the archetypal royal daughter, educated, poised, politically valuable. By her early teens, 
she was already being floated as a marriage prospect across Europe. A brief flirtation 
with the marriage to the future James III of Scotland didn’t pan out. Then the offer came 
from Burgundy. Charles the Bold, Duke of Burgundy, needed a wife. Not for love, of course. This was 
never about love, but for strategy. Burgundy at that time was a kind of semi-independent power 
caught between France and the Holy Roman Empire. It needed allies. Margaret’s brother Edward IV was 
now king of England and an alliance between York and Burgundy would put pressure on France from two 
sides. So Margaret was chosen in 1468. At age 22, she sailed to Bruge and married Charles. She 
never returned to England. Now Charles the Bold was a man with a temper like a lit cannon. He was 
fierce, stubborn, and obsessed with war. But he was also rich, richer than most kings. And his 
court was one of the most glamorous in Europe. Margaret stepped into a world of gleaming armor, 
grand processions, and more embroidery than the Vatican’s laundry room. But beneath the surface, 
trouble. Burgundy, like many small states of the era, was always one bad marriage or one heless 
death away from political collapse. and Charles had no surviving sons. So Margaret, without delay, 
was expected to provide one. Here’s the rub. She didn’t. Historians still debate whether she was 
infertile, whether Charles had his own issues, or whether sheer stress played a role. But no 
children came from the marriage. And in the absence of an heir, Burgundy’s position became 
more precarious. Charles died in battle in 1477, leaving behind a single daughter, Marie of 
Burgundy, from his previous marriage. So Margaret, now a widow, didn’t fade into history as a 
forgotten consort. She became a major player in the next dynastic shuffle. And this is where 
things get messy. Maria of Burgundy inherited a kingdom that had no husband. Every major power 
in Europe saw her as an opportunity. France, the empire, even England, made gestures. Margaret, 
now acting as Marie’s deacto adviser, helped guide her toward a match that would forever change 
the fate of Europe. Maxmillian of Habsburg. Yes, that Maxmillian, the same one who married Marie, 
inherited Burgundy, and merged the Habsburg and Beondian lines, creating the foundation for 
the eventual Holy Roman Spanish superpower combo that would rule half of Europe. That was 
Margaret’s doing. She saw the political winds shifting and chose to throw her support behind 
a match that prioritized dynasty over emotion. Marie and Maxmillian married and with that 
the Habsburgs acquired some of the richest and   most strategically important lands in Europe. 
And Margaret, she stayed in the Netherlands, took a vow of celibacy and became known as the 
great lady of Mecculin. She advised her stepg grandchildren, Philip the handsome among them, 
and managed court affairs with quiet precision. She lived for decades after her husband’s death, 
becoming a kind of daagger queen without a crown, surrounded by the very bloodline she helped 
secure and watching year by year as it began to fold in on itself. You have to wonder what she 
thought as the first signs of Habsburg inbreeding started to appear. She would have seen Philip the 
handsome, who inherited her beagundian refinement, but also a certain manic restlessness. She would 
have heard whispers about his marriage to Joanna of Castile, about the instability, the death, 
the heavy silence. She watched as marriages were arranged between cousins and uncles and nieces. 
She, who came from a court that had fought tooth and nail for legitimacy through war and rebellion, 
must have wondered what kind of future was being   forged now with ink, blood, and holy dispensation. 
A quirky fact. Margaret had a personal devotion to the cult of St. Colette, a reformerous saint 
known for her austere habits and refusal to   compromise. Margaret once had a room in her palace 
where she held regular prayer sessions beneath a ceiling painted with the genealogical tree of 
Christ. Talk about foreshadowing. Lineage was literally the ceiling above her head. Her legacy, 
while often overshadowed by flashier figures, is immense. Without Margaret, the Burgundian lands 
might have fallen into French hands. Without her, Mary might have married a French prince. 
The Habsburg Burgundy fusion may never have   happened. It was her political intuition, not her 
womb, that secured her place in history. So no, Margaret of York wasn’t in bred, but she married 
into a dynasty that would define itself by it. She watched the first threads twist together, 
heard the early echoes of inherited madness, and saw what happens when donastic ambition 
trumps common sense. She died in 1503, aged 57, having outlived her husband, her step-daughter, 
and many of the children she helped raise. Her   bones were laid to rest in Mecculin, where 
a statue still stands, solemn, watching, silent. Next, we return to the root of it all. 
Not just the individuals, but the system itself. It’s time to talk about the grandmothers of 
Marianuanet and the multigenerational tangle that made the French Revolution less of a surprise 
and more of a slow motion train wreck waiting to   happen. Now the candle flickers low and you can 
almost hear the distant rustle of silk skirts and powdered wigs being adjusted in ornate mirrors. 
The century has changed again. We’re in the 18th now, and the spotlight shifts to a group of 
women whose faces you probably wouldn’t recognize, but whose blood ran straight into the storm of 
the French Revolution. These are the grandmothers of Marian Twuinette, a tangle of Habsburgs and 
Bourbons, the Holy Roman Empresses and Spanish Infantas, whose pedigrees looked like antique 
jigsaw puzzles, and whose marriages were less   about love than about strategic genetic recycling. 
Together they helped produce one of history’s most famous royal scapegoats, Maria herself, that 
doomed teen queen with the sky-high hair. And none of them, not a single one, escaped the web 
of dynastic inbreeding. Let’s start with one of the most pivotal pieces, Elizabeth Fesey. Born in 
1692 to the Duke of Palmer and his cousin Dorothia Sophia of Noberg, Elizabeth was already a product 
of the cousin marriage by the time she took her   first steps. She grew up with impeccable breeding 
and big ambitions. In 1714, she married King Philip V of Spain, who, plot twist, was also her 
cousin, albeit once or twice removed, depending on how generously you draw the tree. This wasn’t 
just a personal union. It was the reinforcement of Bourbon Habsburg cooperation through mutual DNA. 
And let’s just say Elizabeth made herself known. She became the de facto ruler of Spain within 
months of arriving, wielding more influence than any courtier had predicted. She produced a brood 
of children who would scatter across Europe and bring that distinctive Hapsburg bourbon blend 
to every palace from Naples to Palmer. One of those children was Maria Theresa Raphael of Spain. 
Now, she doesn’t get a lot of screen time in most history books, but here’s where the branches start 
to loop dangerously close together. Maria Theresa was married off to Louis Dofan of France. the son 
of Louis X the 15th again Bourbon meets Bourbon their daughter would have been a future queen of 
France but Maria Theresa died young because of   course she did from complications in childbirth at 
the age of 20 her death was considered tragic yet completely expected another royal woman another 
body sacrificed to the endless machine of air production but she wasn’t the only grandmother 
in this lineage meanwhile over in Vienna we find another titan of donastic strategy Empress Maria 
Theresa of Austria. Now you might be thinking, “Wait, isn’t that Marian Twinette’s mother?” Yes, 
but stick with me. The story begins earlier. Maria Theresa was the daughter of Emperor Charles 
V 6th and Elizabeth Christine of Brunswick   Wolfenbut. A mouthful of a name for someone who, 
by the time of her marriage, was considered a reasonable genetic bet despite already having 
Hapsburg ties. Her daughter, Maria’s Theresa, would go on to rule as empress in her own right, 
a rare, formidable woman in a sea of powdered men. And she did what every Habsburg ruler was supposed 
to do. Marry strategically and marry repeatedly. Maria Theresa had 16 children. 16. And almost 
every one of them was used as a diplomatic tool. She married her daughters into every eligible 
royal house in Europe like a living game of   risk. Each union carefully calculated to reinforce 
Habsburg influence. One daughter went to Palmer, another to Naples, another to Mena. and one 
Alstar Marie Antuinette was sent to France. Now, here’s the genetic kicker. These children weren’t 
marrying strangers. They were marrying Pisdons, second cousins, occasionally nephews. Some of 
the Bourbon matches included bloodlines that had already tangled it with Habsburg stock 
three or four times in the past century. Marian Antuinette, for example, married Louis 
August, later Louis V 16, who was her cousin through multiple shared ancestors, including 
Louis the 14th and Philip the fourth of Spain. Their family trees weren’t just entwined. They 
were practically hugging, and it showed. Marian Twuinette’s facial structure, the long nose, the 
slight chin, had echoes of her great-grandmother’s portraits. She had difficulty conceiving 
for the first several years of her marriage,   which created scandalous rumors and deep court 
anxiety. And while she eventually had children, her son Louis Sha, who would become Louis the 
70someth in title only, died in prison during the revolution, likely from tuberculosis and neglect, 
but possibly also from a compromised immune system that couldn’t fight off even the smallest 
infection. A quirky fact buried in all this. Marian Twuinette’s maternal grandmother, Elizabeth 
Christine, was known for keeping peacocks as pets, like actual peacocks. She claimed their mournful 
cries reminded her of the Virgin Mary’s sorrow, which tells you everything you need to know 
about the general psychological atmosphere of the   Habsburg court. Grand symbolism, religious guilt, 
and a sprinkling of melodrama served fresh daily. The scholarly debate surrounding these women, 
these grandmothers of decline, is layered. Some historians argue that the Habsburgs and Borbins 
were simply doing what they had to do in an age   where alliances mattered more than health. Others 
with the benefit of genetic hindsight claimed that this relentless cousin matching created a fragile 
elite, intelligent, yes, but emotionally erratic, reproductively challenged, and prone to premature 
death. One modern genealogologist referred to the line that led to Marianuanet as a downward spiral 
in silk gloves, which is both haunting and frankly accurate. And what’s tragic is that these women 
had no choice. Maria Theresa Raphaela didn’t pick her husband. Empress Maria Theresa loved her 
children fiercely, but used them like bargaining chips. Elizabeth Farese controlled policy, but 
not biology. They were all trapped in the same gilded cage, expected to breed for the glory 
of the state, even if it meant watching their   daughters die in childbirth or their sons grow 
sickly and suspicious. Their descendants would sit on thrones, yes, but also in wheelchairs 
and sick beds and eventually in prison cells. And while we remember Marie Antuinette for her 
hair, her diamonds, and her guillotine, it’s worth   remembering the women who came before her who 
built the staircase she would one day be pushed down. Next, we’ll leave the throne rooms and slip 
into the quieter chambers, where miscarriages, mysterious illnesses, and hushed funerals show 
us the true cost of dynastic obsession. Hidden behind veils, whispered down corridors, and 
recorded only in the margins. Now, the echoes of royal proclamations fade, and we pass through a 
smaller, quieter door. The one behind the throne, the one where royal women lived when they weren’t 
being paraded in ceremony or posed for portraits. Here is the world of miscarriages, mystery 
ailments, locked bed chambers, and the silences that followed. For all the crowns and titles 
we’ve wandered through, this is where the real cost of inbreeding and its relentless demands 
was often paid, not in courtrooms, but in the shadowy space between cradle and coffin. Tonight, 
we descend into the personal tragedies of medieval and early modern queens. the ones no historian 
ever bothered to paint and the ones whose stories were often smothered under layers of euphemism and 
incense. Let’s start with a grim but consistent reality. Childbearing among royals was a full-time 
occupation and failure was not an option. But failure came anyway again and again. Miscarriages, 
still births, infants who lived only long enough to be baptized and wrapped in white silk. Royal 
records rarely list these events clearly. Instead, you get vague phrases like, “The queen was unwell, 
a sorrowful occurrence,” or, “I truly understated moments,” an heir was expected, but none came. In 
between those phrases are lifetimes of heartbreak, blood loss, and buried children whose names that 
were never even recorded. One of the most well   doumented cases is Katherine of Araggon. 
As we explored earlier, she had at least six pregnancies during her marriage to Henry VIII, 
and only one child survived, Mary Tuda. Her other pregnancies ended in miscarriage or early infant 
death, including a boy who lived for just a few weeks. The pressure on her was astronomical. The 
emotional toll was invisible. What we rarely talk about is that Catherine believed God was punishing 
her. And that belief was reinforced by everyone around her. There were no conversations about 
recessive genes or age incompatibility. There was only guilt, penance, and prayer. But Catherine 
was far from alone. Joanna of Castile, her sister, also suffered miscarriages. So did Isabella of 
Portugal, who had three children that didn’t survive beyond infancy. So did Barbara 
of Austria. So did countless others. It became a pattern so frequent that royal courts 
built entire protocols around the expectation   of death. Cribs were ordered and placed in rooms 
that were already being measured for tiny coffins. Midwives doubled as morticians. Morning veils 
were stored in the same drawers as baptismal   gowns. The medical understanding of these losses 
was of course painfully limited. Queens were bled, fed herbal mixtures subjected to prayers and 
rituals designed to balance the humors. In some courts like Spain and Austria, it was believed 
that excessive devotion could cause uterine   melancholy, a madeup illness that basically 
blamed religious piety for infertility. The irony is almost cruel. These women were expected 
to be saints and broodmares at the same time. Now enter the real horror show. The mystery ailments, 
chronic headaches, muscle wasting, sudden fevers, swellings, hysteria, hallucinations. Many royal 
women began experiencing symptoms in their late teens or early 20ies, especially after their 
first pregnancies. Some of this could be chocked up to poor nutrition, infections, or the general 
stress of being locked in a velvet cage for life. But increasingly modern scholars point 
to inbreeding as a contributing factor,   specifically the accumulation of recessive genetic 
conditions like hemophilia, epilepsy, or certain forms of autoimmune disease. Take Anna of Austria, 
Philip II’s niece wife. She bore several children, including the future Philip II, but her letters 
suggest chronic exhaustion, anxiety, and what we’d now call postpartum depression. She died at 
30 after yet another pregnancy. Nothing dramatic, nothing scandalous, just one more royal body 
that quietly collapsed under the weight of doing   what was expected. Or look at Isabella of Bourbon, 
mother of Maria Burgundy. She had recurring fevers that never fully went away after childirth. 
Historians believe she may have had lupus or another autoimmune disease, conditions that we 
now know can have genetic origins and flared   dramatically after pregnancy. She died young 
like so many others and was remembered mostly for being obedient and modest. And then there are the 
cases that defy even modern classification. Women who suddenly became mad, screaming at nothing, 
talking to ghosts, refusing to eat. Sometimes they were locked away, other times simply declared 
unfit and replaced. Hana of Castile’s mental health struggles have been endlessly debated, 
but she’s just the most famous example of a   much larger pattern. Were these psychological 
collapses, brain tumors, genetic neurological disorders? We may never know. What we do know 
is that they almost always occurred in women from families that had been marrying cousins for 
generations. One particularly chilling example, Elellaner of Austria, sister to Charles V. 
She suffered severe insomnia, hallucinations, and what her doctors called womb-driven confusion. 
her treatment, bleeding, isolation, and enforced silence. She recovered sort of a royal and went 
on to marry the king of France. But court records show she never bore a healthy child, and she died 
early, remembered only for her looks and her good behavior. And the children, oh, the children, so 
many royal infants were born sickly, with what were politely termed delicate constitutions. 
There are accounts of princes with seizures, babies who bled excessively from small wounds, 
or toddlers who failed to develop language or coordination. The word ricketetts appears 
frequently. So does wasting. In many cases, these children were hidden away, raised in 
private until they either miraculously thrived   or quietly disappeared from the record. A quirky 
and tragic footnote. In the Austrian court, it became customary in the 17th century to commission 
miniature coffins for children in advance just in case. These were painted with scenes of heaven, 
angels, and family crests. Some even included tiny gowns and lace pillows tucked away in drawers 
near the nursery. That’s how common infant death had become. That’s how normal the abnormal had 
turned. Modern historians continue to debate the role of inbreeding in all this. Some say it’s 
overstated. The poor sanitation and lack of   antibiotics played bigger roles. Others argue that 
once you stack enough cousin marriages, the odds of recessive conditions showing up multiply. And 
in the royal houses of Spain, Austria, and France, those odds were exploited past the breaking point. 
What’s undeniable is the emotional toll. Royal women were expected to perform miracle after 
miracle, get pregnant, deliver a living child, and return to court within days looking radiant. 
When they failed, when their bodies betrayed them, the blame was swift and brutal. Their husbands 
took mistresses, their advisers whispered, the people judged, and the women themselves. They 
rarely left behind letters that expressed the full weight of what they felt. Only scraps, a sentence 
here, a note scrolled in a prayer book, a single line from a midwife. The queen weeps alone. Next, 
we’ll explore what may be the most visible symptom of this entire dynasty’s collapse. The infamous 
Habsburg jaw, its physical manifestations, its roots, and the women who bore it forward 
across generations like a badge and a burden. Now, we arrive at the most infamous facial feature in 
European history. The protruding, squared off, cartoonishly memorable Habsburg jaw. You’ve seen 
it in portraits, perhaps without even realizing. That elongated lower face, the thick jawbone 
jutting proudly from beneath tightly pursed lips, a chin that looks like it could deflect cannon 
fire. It appears generation after generation, passed down like a royal scepter. And it became 
more than just a physical trait. It became a   symbol of power, of stubborn bloodlines, and 
of what happens when you marry your cousin and then keep doing it over and over for centuries. 
Let’s break it down. The Habsburg jaw, technically called mandibular prognithism, is a condition 
where the lower jaw extends beyond the upper jaw,   creating an underbite. In mild cases, it just 
looks like a strong chin. In severe cases, which the Habsburgs eventually achieved with terrifying 
efficiency, he caused difficulties with speech,   chewing, and even breathing. Modern medical 
researchers have studied portraits, exumed skulls, and even compared royal death masks to reconstruct 
the history of this trait. And what they found, it got worse with time. Much worse. While both 
men and women in the Hapsburg line showed signs of the jaw, it’s the women who had to wear it 
differently. A man could parade his prominent chin as a badge of authority, a symbol of dynasty. 
But for women, it was a different story. Beauty mattered, elegance mattered, and the Habsburg 
jaw was about as subtle as a battering ram. In portraits, you can see how artists tried to soften 
or hide it. Lips are blurred, shadows painted just so, angles manipulated to de-emphasize the 
jut. But the bone doesn’t lie, and neither does the history. Take Isabella Claraara 
Eugenia for example. In her early portraits, her chin is only slightly pronounced. Her 
paintings depict her with the dignity, composure, and what you might call a mild prognosis. But 
by the time we get to Maria Anna of Spain, granddaughter of Philip the third, the jaw is 
undeniable stark, angular, nearly anatomical. Her portraits look stiff, not because of her posture, 
but because the painter is struggling to present   her in a flattering light without painting what 
was essentially a built-in anatomical protest against beauty standards. And then there’s Mariana 
of Austria, both niece and wife to Philip IV. Yes, niece and wife. Her jawline was so famously 
exaggerated that contemporary observers commented on it even in a time when royal flaws were 
supposed to be politely ignored. “Her face is noble,” wrote one ambassador, but curiously 
extended at the chin, which is court speak for she looks like she’s chewing on something invisible. 
“Mariana had trouble closing her mouth fully. She suffered frequent jaw pain and yet she 
gave birth to the last and most tragic bearer of the Habsburg jaw, Charles II of Spain. 
We’ll get to Charles in more detail soon, but just know for now, the jaw reached its final 
form in him. His mandibular prognathism was so severe that he couldn’t chew properly. He drooled, 
slurred his speech, and needed to be spoonfed soft   foods well into adulthood. His jawbone wasn’t just 
cosmetic, it was disabling, and it was inherited. specifically from a line of women who had passed 
it along generation by generation, often without even understanding the damage they were carrying. 
Now, here’s the wild thing. Modern geneticists have studied the degree of inbreeding in this 
dynasty and found something jaw-droppingly, pun, fascinating. A study from 2009 used facial 
analysis and genealological data to track the correlation between the jaw and the level of 
inbreeding. They discovered that the severity of   the Habsburg jaw directly matched the coefficient 
of inbreeding. In simpler terms, the more cousin marriages in a person’s ancestry, the bigger 
the jaw. And it wasn’t just the jaw. Alongside it came other facial traits now understood to be 
linked to inbreeding. White set eyes, long noses, narrow pallets, drooping eyelids. In some cases, 
women were reported to have difficulty with speech development as children or struggled with dental 
alignment severe enough to cause chronic pain. So why did no one stop it? Why did these families 
staring at children who could barely speak or chew keep marching forward with cousin marriages? The 
answer is both simple and horrifying. Power. These marriages weren’t about love or health. They 
were about sealing borders, preserving wealth,   and avoiding the chaos of foreign claims to the 
throne. A cousin was safer than a stranger. The niece was even better. And if the result was 
a jaw that looked like he could store walnuts,   well, that was a small price to pay for empire. 
A quirky fact, the Habsburg jaw made it into satire. In 18th century plays and pamphlets, 
especially in France and the Netherlands, the trait was exaggerated in political 
cartoons to mock Spanish royalty. One   popular image showed a noble woman with a chin so 
long it had its own crown. In these depictions, the jaw became shorthand for everything wrong with 
dynastic inbreeding. Arrogance, dysfunction, and self-destruction wrapped up in courtade. And yet 
there were women who wore it with dignity. Maria Theresa of Austria, Marianuanet’s mother, had a 
strong jawline, and while not as severe as later generations, it was noticeable. Still, she ruled 
with authority, had 16 children, and maneuvered through the political maze of enlightenment 
Europe without letting her facial structure   slow her down. Her portraits don’t try to hide her 
chin. They own it. Is almost a flex. Yes, I have the jaw and I still run this empire. Historians 
still argue about whether the jaw itself caused suffering or was just a visible marker of 
a deeper problem. Some say it was symbolic, proof of inbreeding, yes, but not itself a cause 
of collapse. Others point out that the jaw wasn’t just an unfortunate trait. It was the tip of the 
genetic iceberg. Behind it were immune disorders, fertility issues, and neurological problems that 
couldn’t be painted over. The women who carried the jaw weren’t villains. They were trapped. 
Trained from birth to understand that their   greatest value lane continuing the dynasty. They 
married as instructed, bore children as demanded, and passed on not just titles, but traits that 
haunted their descendants. When they looked in   the mirror, did they recognize it? Did they see 
the chin as a sign of duty or a curse? Next, we’ll step into the heart of this debate, where scholars 
and scientists clash over what really brought down   these dynasties. Was it the jaw, the madness, or 
something more subtle? Let’s pull apart the myths and see what’s left when the velvet curtain drops. 
Now we draw closer to the edge of understanding. Past the portraits and court rituals, past 
the bloodlines and gilded ledgers, and into the minds of scholars who’ve spent centuries 
arguing over one thing. What really brought down the great dynasties of Europe? Was it truly 
inbreeding that cracked the thrones of Habsburg, Spain, and Bourbon, France? or have generations 
of storytellers simply turn genetic quirks into myths because the truth is harder to pin down. 
In this section, we slip behind the textbooks and step into the quiet, obsessive corners of 
academia, where historians, doctors, and data nerds battle over whether madness, infertility, 
and physical deformity were a product of royal policies or exaggerated symptoms of dynasties 
already teetering for entirely different reasons. Let’s start with one of the biggest ongoing 
debates. Was inbreeding the cause of raw mental   instability or just a convenient excuse? The most 
frequently cited example, of course, is Joanna of Castile. She’s remembered as Joanna the Mad, the 
nickname handed to her by men who needed her out of the way. She talked to the dead. She screamed 
during storms. She was locked in a convent for most of her adult life. But historians today can’t 
agree on whether her breakdown was genetic or situational. Yes, she was the product of cousin 
marriage. Yes, mental illness ran through her   family. But she also endured forced separation 
from her children, intense political pressure, and a court that weaponized her grief to 
discredit her. One camp of scholars believes   Joanna may have had bipolar disorder exacerbated 
by trauma. Others say paranoid schizophrenia. Still others argue she was simply a woman reacting 
very normally to being surrounded by powerful men trying to institutionalize her. It’s not a small 
question because if Joanna was genuinely ill, she may represent one of the earliest documented 
cases of inherited mental instability in royal   lines. If she wasn’t, she’s proof that the mad 
queen narrative was often used to cover political coups with a layer of faux medical legitimacy. The 
same arguments swirl around others. Charles V 6th of France, for example, famously thought he was 
made of glass and would shatter if touched. Sounds like madness, but was it the result of generations 
of close blood marriages and the Valoir line? Or was it the crushing pressure of kingship in a 
collapsing feudal state? Charles II of Spain, who we’ll get to soon, is often described as 
mentally challenged, physically debilitated, and emotionally immature. But again, we’re relying 
on letters written by courtiers with motives, physicians with 17th century knowledge, and 
portraitists who painted what they were told   to. Another major debate lies in the realm of 
infertility and still births. Was it the result of genetic disorders, or was it just the tragic 
norm of preodern child birth? It’s true that royal women often miscarried or had children who died 
young. Catherine of Araggon, Barbara of Austria, Isabella of Bourbon. The list is long, but so 
is the list of commoner women who faced the same tragedies. The difference? Royals were expected 
to produce healthy heirs like clockwork. When they didn’t, people started looking for patterns, and 
they often found them in the family tree. Recent studies have tried to measure this. Geneticists 
working with historical data have looked at the   inbreeding coefficient, the number that represents 
how likely someone is to inherit two copies of the same gene from a common ancestor. The average 
person’s number is around zero. The higher the number, the more likely genetic disorders are to 
show up. Charles the sect of Spain, his imbreeding coefficient was calculated at 0.25, the equivalent 
of a child born to siblings. That’s not rumor, that’s math. But most queens didn’t reach that 
number. Their coefficients hovered around 0.06 to 0.125, comparable to first cousin marriages. 
Dangerous, yes, but not an automatic death sentence. Here’s where things get blurry. Critics 
argue that modern science loves a clean narrative, and inbreeding is a tempting villain. It’s easier 
to blame a jaw or a mental breakdown on DNA than on politics, warfare, or misogyny. For every 
scholar who claims the Habsburgs were undone by their own chromosomes, there’s another who says, 
“Hold on, maybe it was economic mismanagement, climate change, religious fragmentation, 
or a hundred other factors. After all, France didn’t fall because of Maranuinette’s 
lineage. It fell because the people were starving, and the crown kept pretending everything was 
fine. Then there’s the issue of propaganda. Royal women were often deliberately discredited by rival 
factions who needed a reason to remove or sideline them. Calling a queen baron mad or deformed was 
an easy way to shake public confidence in the   regime. And once the rumor started, it stuck. 
Maria Theresa of Spain was painted as slow and clumsy by French courtiers who didn’t want her at 
their side. Elizabeth of Valawir was said to be emotionally unstable, mostly because she didn’t 
enjoy being ignored by her much older husband. were these real conditions or just slander in 
satin. Even the Habsburg jaw itself might be more myth than malady in some cases. Modern facial 
analysis of painted portraits is, let’s be honest, a little subjective. Artists flattered their 
subjects, exaggerated features to emphasize nobility and operated under stylistic conventions 
that might have made a normal chin look dramatic. Some scholars believe the jaw became a symbolic 
shorthand for degeneracy rather than an actual physical marker in every case. Once people 
started seeing it, they saw it everywhere. A quirky but telling example in the 19th century, 
long after the Spanish Habsburg line had ended, European race theorists started using the 
Habsburg jaw as evidence of racial purity gone wrong. A twisted kind of reverse eugenics. They 
claimed it was what happened when you tried to   keep a bloodline too pure. This idea filtered into 
medical textbooks, cartoons, and even early film. By the 20th century, the Habsburg jaw wasn’t just 
a medical condition. It was a cultural punchline. So, where does that leave us? Probably somewhere 
between truth and theater. Yes, inbreeding led to real measurable problems. Yes, the dynasties 
that embraced cousin marriage suffered more from mental and physical issues over time. But no, 
not every royal woman who miscarried was cursed. Not every queen with a long face was deformed. And 
not every dynasty collapsed because of bad DNA. Sometimes they were just bad at ruling. But the 
myth persists because it’s tidy. Because it gives us a way to look at power and say, “Well, that’s 
what they get. It’s poetic justice carved into bone.” Next, we head into the final loop of this 
twisted tale. To the women behind the fall of the Habsburg line. Not just victims of biology, but 
key players in the dynasty’s implosion. We’ll meet the ones who gave birth to the end, one chromosome 
at a time. Now the spiral begins to tighten. We’ve danced through portraits and letters, medical 
oddities and court intrigues. But this next part, this is the slow motion collapse. The genetic 
endgame of royal Europe playing out in the marble halls of palaces and the whispered prayers 
of midwives. Tonight we focus on the women who are more than just carriers of crowns and 
dynasties. These women were the genetic glue, the final binding agents in centuries of strategic 
intermarriage meant to keep power consolidated. Except, of course, the glue had been thinned by 
time and stress and too many shared ancestors. These queens didn’t just pass on kingdoms. They 
passed on the quiet ticking of dynastic collapse. Let’s begin with Mariana of Austria. A name 
you’ve heard already. Or have we? She married her uncle Philip the IV 4th of Spain in a move 
so genetically reckless it might as well have been shouted across Europe. Mariana was the 
daughter of Maria Anna of Spain who herself was the sister of Philip for both. So when Philip 
married Mariana, he married his sister’s daughter. If your brain is buzzing, that’s the sound 
of your family tree folding in on itself like   origami in a wind tunnel. Their marriage was meant 
to keep the Spanish and Austrian branches of the Habsburgs locked together. But the result was 
Charles II, the final Habsburg ruler of Spain, who was a medical disaster in royal drag. Mariana 
had a brutal role. She was expected to produce heirs from a gene pool that had long since 
stopped offering options. She had five children   with Philip Bol. Only one, Charles, survived. 
And what a survival it was. From birth, Charles had difficulty feeding, delayed development, and 
physical abnormalities so pronounced that court physicians started suggesting he might be unfit to 
rule before he could even walk. Mariana loved him fiercely. She became his regent after Philip’s 
death and ruled Spain in his name for years, trying to hold together a kingdom that was falling 
apart in more ways than one. But Mariana wasn’t alone in this final wave of fragile royalty. 
Across Europe in the Austrian court, Maria Anna of Austria, another cousin, was marrying 
Maximleian II, Emanuel of Bavaria. Their son Charles Albert would go on to become Holy Roman 
Emperor, but he too bore signs of the dynasty’s increasingly precarious bloodline. He suffered 
from chronic migraines, extreme mood swings, and what one courtier described as episodes of 
great confusion. He was brilliant, yes, but also volatile, emotionally distant, and physically 
weak. His marriage to Maria Malia of Austria didn’t help much since she was his cousin and also 
a Habsburg. Meanwhile, in the southern stretch of the Habsburg Empire, the Kingdom of Naples was 
seeing similar echoes. Maria Amalia of Saxony, married to Charles III of Spain, was another cog 
in the familiar recycling system. Though not a Habsburg by name, she was the result of similar 
intermarriages among German and Italian nobility. Her children included Ferdinand the FK of the two 
Sicilles whose descendants would keep showing up in various royal bloodlines with alarming health 
issues. Low fertility, club feet, epilepsy. The court physician once observed that the blood is 
noble but exhausted. That’s about as poetic as a diagnosis gets. A quieter, often overlooked figure 
in this genetic domino effect is Margaret Theresa of Spain, the daughter of Mariana and Philip 
IV and technically Charles II’s older sister. She was married off to Leopold I, her maternal 
uncle. Yes, again, a brother marrying his niece. Margaret was only 15 at the time. Her marriage was 
celebrated with fanfare and art. She’s the girl in the center of Velasquez’s Las Maninas, that eerie 
portrait where even the dog looks uncomfortable. But Margaret’s life was short. She gave birth to 
four children, only one of whom survived infancy. She died at 21, likely from complications of 
pregnancy, a condition that kept reoccurring   in women who are increasingly expected to bear 
children from men who shared large chunks of their DNA. Let’s pause for a curious twist. Throughout 
all of this, many of these women were renowned for their piety. Marian of Austria practically 
lived in black, attending mass constantly and surrounding herself with confessors. Margaret 
Theresa was praised for her obedient virtue. Maria Malia was known for fasting during Lent 
to the point of fainting. And yet, these women, devout, obedient, and royal to their bones, were 
caught in a system that rewarded their faith with declining bodies and broken lineages. There’s also 
a strange shift happening here. The royal women of earlier centuries were mostly passive figures in 
their dynastic stories, shipped from one court   to another, bred like prized mares. But these 
late Habsburg queens, they had agency, and that made the tragedy feel sharper. Mariana wielded 
political power, oversaw military decisions, and held her ground in the face of papal meddling. 
Margaret Theresa corresponded with philosophers. Maria Anna of Austria funded libraries. These were 
not shrinking violets. They were smart, engaged women who were just boxed in by the genetics 
of ambition. And the debates rage on. Some historians insist that the collapse of the Spanish 
Habsburgs was purely political wars, debt, empire overstretch. Others point to the raw biological 
data, the skyhigh in breeding coefficients, the accumulation of physical and mental defects, 
early deaths and childless marriages. Still others argue it was both. That the genetic frailty was a 
metaphor made literal. That a system so obsessed with preserving itself eventually built a 
throne no one healthy enough could sit on. Quirky historical side note. One physician during 
Charles II’s time insisted that the only cure for the royal family’s decline was to introduce fresh 
blood through the modest veins of a commonborn maiden. He was promptly dismissed, but he may have 
been the only one in the room with the right idea. By the time the 18th century dawned, it was clear 
something had gone deeply wrong. Heirs were harder to come by. Queens were dying younger. Royal 
families were importing brides from increasingly distant houses just to keep the recessive 
traits at bay. But for Spain and Austria,   it was already too late. The women who had 
been tasked with holding it together, Mariana, Margaret, Maria, Anna had done everything expected 
of them. They had prayed, they had married, they had given birth, but in the end they were the last 
glue sticks in a collapsing sculpture. Beautiful, brittle, and doomed from the start. Next, 
we’ll peer into the weirdest corridors of these royal family trees. Those fringe cases where 
a woman was her own aunt, where brothers married sisters-in-law twice removed, and where political 
desperation created marriages so tangled even the Vatican raised its eyebrows. Now, we plunge into 
the strangest corners of the medieval and early modern royal gene pool. the kind of branches on 
the family tree where you’re no longer sure which direction is up and where a woman might be her own 
aunt, her cousin’s stepmother, and possibly her   future daughter-in-law if things go just slightly 
more sideways. These are the fringe cases, the genealogical accidents born not just of inbreeding 
but of pure donastic desperation. Because when power is the only real inheritance and everyone 
else is considered too politically risky to marry, the nobility starts to get creative and 
occasionally too absurd. Let’s start with one of the most bewildering of examples. Anna of 
Austria. Yeah, yes, another Anna. Don’t worry, this one comes with extra footnotes. She was both 
the niece and the fourth wife of King Philip II of Spain. That’s right. Philip had already been 
married three times. Once to Mary Tudtor of England, then to Elizabeth of Valawir, and then 
briefly widowed when he decided to marry Hannah, the daughter of his sister Maria and Emperor 
Maxmillium Falcon. So to break that down, he married his sister’s daughter, Louie, which made 
his new wife also his niece. And when they had children, they were also Philip’s grand nephews 
by blood. One of those children would grow up to be Philip III, perpetuating the Habsburg legacy 
of jaw lines and crossed chromosomes. Hannah’s case is infamous, but not unique. In fact, the 
Habsburgs, in particular, began specializing in marriages where multiple family roles could be 
filled by one person. The logic went something like this. If your cousin is already Catholic, 
already wealthy, and already on your Christmas card list, why waste time importing someone new? 
It’s the 16th century version of online dating with one filter. Must be related to me in at least 
two ways. Another bizarre case, Marie Antonia of Austria, daughter of Emperor Leopold Fefer and 
Margaret Theresa of Spain. Remember her? The girl from Las Maninas? Well, she was married off 
to her cousin Maximleian II Emmanuel of Bavaria, which made her both duchess and eventually stepg 
grandmother to her own great niece through a later   union. If you’re old squinting at that sentence 
trying to find the logic, don’t worry. The royal genealogologists of the time often needed charts 
the size of carpets to keep it all straight.   It got so convoluted that at least one court 
historian attempting to describe the lineage of Maria Antonia’s descendants wrote, “Let the blood 
be noble even if the map is incomprehensible.” Then there’s Maria Anna of Bavaria who married 
her maternal uncle, Ferdinand I, Holy Roman Emperor. She was his niece, and again, no one 
at the time thought this was especially odd. The Vatican had to sign off on a dispensation for 
nearly every royal wedding at this point because canon law technically prohibited such close 
unions, but it had become almost a formality. These weren’t marriages made for morality. They 
were treaties in briade. What’s even stranger is how these tangled lines were treated a court. 
People didn’t flinch when someone married their aunt’s widowerower or their half-brother’s son. 
Instead, they applauded it as a show of dynastic loyalty. You weren’t just preserving the family 
legacy, you are wrapping yourself in it like a   velvet cloak lined with second cousins. And if 
you squint hard enough, you’ll find cases where two sisters married the same man one after 
the other so the kingdom wouldn’t lose a   dowy. Sometimes that man was also their cousin or 
uncle or both. A particularly murky case involves Blanch of Bourbon who was married off to Peter 
of Castell and then abandoned within days. Peter married again bigously to Maria de Padilla who was 
actually related to Blanch through two different lines. Some sources say Peter’s entire reason for 
discarding Blanch was that she didn’t produce a child immediately. Others say he just preferred 
Maria. But the court didn’t protest because even his second choice was close enough in blood 
to pass muster. One of the more uncomfortable examples comes from Joanna of Austria, who 
was asked to consider marrying her own nephew   at one point to maintain unity between Spain and 
Portugal. The plan fell through, not for genetic reasons, but because political tides shifted. 
Had it happened, she would have been both aunt and wife to the same man, and history wouldn’t 
have blinked. Just another loop in a tapestry woven entirely out of cousin knots. A quirky 
eyebrow raising trend that emerged from these interf family marriages. the use of dynastic baby 
naming loops. In many of these tangled families, the same names were recycled every generation. 
Maria, Anna, Isabella, Philip, Charles, until entire branches of the tree had identical 
names and birth years. In court documents, you had to specify which Maria Anna you were talking about 
by including her father’s name and often her birth order. Imagine an entire palace where three women 
named Maria Anna lived within shouting distance of each other, each married to a different cousin. 
And yes, that really happened. Historians still puzzle over how these bizarre marriages were 
sustained. The working theory, donastic paranoia, the fear of delusion. These families believed 
that only they were noble enough, Catholic enough, and rich enough to marry themselves. The concept 
of marrying down was worse than disease. So they kept us in the family literally. The resulting 
relationships were less about affection and more about strategic entrapment. You didn’t marry for 
love. You married so that no one else could claim your throne through a different womb. And here’s 
the wildest twist. This pattern wasn’t confined to monarchs. Even minor nobility trying to emulate 
royal behavior began marrying their cousins and nieces. So the inbreeding pyramid widened at the 
base. What started with kings and queens spread into the ducal and bonial classes until Europe 
was essentially one large interrelated brunch party with way too much velvet and way too little 
gene flow. But eventually the structure began to wobble as more children were born sick as more 
marriages ended in childlessness or deformity. Even the most diehard dynasties began to falter. 
Genetic counselors didn’t exist. But reality did. Monarchs started looking farther a field. German 
princesses were imported to Britain. French dukes married Danish brides. The intermarriage continued 
the loops began to uncoil slowly, painfully, and far too late for many. Still, these fringe 
marriages leave behind a strange legacy. A paper trail of alliances so convoluted they almost 
feel fictional, but they weren’t. These women, brides, nieces, sisters, second wives of second 
cousins were real. They lived within the tightest constraints ever stitched into briade. They were 
told over and over that love doesn’t matter, but lineage does, and they obeyed, even when it 
meant becoming their own aunt by marriage or their cousin’s second wife after their sister died. 
Next, we walk into the final echo chamber of this bloodline. The collapse that everyone saw coming, 
but no one stopped. It’s time for Charles II of Spain, the ultimate product of inbreeding and the 
final breath of the once great Habsburg line. Now the lights dim, the tapestries sag, and the echo 
of palace doors closing reverberates through a hollowedout empire. All threads converge here 
in the fragile, faltering figure of Charles II of Spain, a monarch so famously embred that he’s 
become the poster child for the consequences of royal genetic enttrapment. Every story we’ve told, 
every woman who married her cousin or bore a child to her uncle, all of it leads to this one final 
human blueprint. Charles wasn’t just a king. He was a culmination. The Habsburg dynasty had spent 
centuries folding itself inward. And in Charles, the folds began to tear. He was born in 1661 to 
Philip Vor and Mariana of Austria, who, as you’ll remember, was Philip’s own niece. That alone gave 
Charles a mind-melting inbreeding coefficient of 0.254, equivalent to the genetic relationship of 
a child born to siblings. His family tree doesn’t branch. It loops like a moious strip with ruffles. 
And when Charles arrived, it showed. Right from the beginning, everything about him was wrong. He 
couldn’t talk until age 4, couldn’t walk properly   until past age 8. He drooled constantly. He 
suffered frequent seizures. And yet he was made king at age four because well that’s pal 
Monarchy’s work. His court physicians were at a loss. Desperate to explain his condition without 
admitting the obvious. They blamed everything from demonic interference to the corruption of the 
humors. He was subjected to exorcisms, multiple. The clergy anointed his bed with holy oils. 
Priests chanted over his food. The superstition swirled because no one wanted to say it plainly. 
The boy’s body was crumbling under the pressure   of inherited genetic collapse. Even his immune 
system seemed broken. He caught every illness that came within a mile of Madrid and survived most of 
them only because he was smothered in attention and probably herbal wine. Charles’s face was 
unmistakably Habsburg. His mandibular prognathism, or Habsburg jaw, was so severe he couldn’t 
properly chew solid food. His upper teeth didn’t meet his lower ones, and his tongue was too large 
for his mouth. He spoke with difficulty, slurring and mumbling, often repeating himself in long 
loops. His court translators, yes, translators for his native language, learned to decode his speech 
the way one might learn to understand the rhythm   of a broken bell. And yet, despite everything, 
they married him off twice. Because hope, or maybe denial, rings eternal in royal courts. 
His first wife was Marie Louise of Orlon, a French princess. She was 15, vibrant, and by all accounts 
quite sweet. She was also reportedly terrified of Charles. He was sickly, awkward, and utterly 
dominated by his mother, Mariana, who still ruled behind the scenes. Their marriage lasted 
10 years. Marie Louise never became pregnant, not once. Whether that was because of her or 
Charles is still debated, but Charles’s inability to consumate the marriage was an open secret. One 
contemporary wrote, “The king retires each night as if to a prayer cell, and the queen emerges 
each morning as unsatisfied as she entered.” Mary Louise died suddenly in 1689 at just 26. 
Poison was rumored, because of course it was, but modern scholars suspect she simply collapsed 
from stress and illness. Charles was devastated. And the Habsburgs, they lined up the next wife, 
Inter Maria Anna of Noberg, a German princess with 23 siblings. Yes, 23. Chosen because her family 
was famously fertile. The thinking was, if anyone could get pregnant with a child of Charles, it 
would be her. Spoiler alert, she didn’t. Their   marriage was colder than the stone halls of the 
Escoreal Palace. Maria Anna spent much of her time praying, writing letters home, and dodging 
the enormous pressure of producing a miracle air   from a man who could barely stand unassisted. 
Charles’s decline was slow but relentless. His body twisted under its own weight. His hair fell 
out, his eyesight dimmed, his hearing grew worse. By the time he was 30, he looked 60. By 35, he was 
nearly blind and suffering from what was likely some form of neurodeenerative disorder. In his 
final years, he became obsessed with death. He kept skulls in his chamber and demanded to watch 
autopsies. He ordered his ancestors remains exumed so he could look upon the past and reportedly 
kept bits of saintly relics in his pockets. He was convinced he was cursed and in a way he wasn’t 
wrong. A quirky and chilling side note. In one of the last letters written by a court official, 
Charles is described as the man who lives but   is already passed. He had stopped speaking 
coherently. His muscles had begun to waste, drooled constantly. His sleep came in jagged 
snatches. And yet, Spain still called him king because there was no plan B. When Charles died in 
1700 at the age of 38, his body was so misshapen that inbalamas reportedly struggled to preserve 
it. His autopsy, possibly embellished by horrified physicians, noted that his heart was the size of 
a peppercorn. His lungs corroded, his intestines rotted, and his brain filled with water. Whether 
these descriptions were accurate or rhetorical, they captured the general feeling. Charles 
had been more symbol than sovereign. The final breath of a dynasty too proud to admit it had been 
suffocating for generations. With Charles’s death, the Spanish Habsburg line ended completely. No 
children, no heirs, no backup cousins with strong enough blood to claim the throne. His passing 
sparked the War of the Spanish Succession,   a massive European conflict that redrew borders, 
and finally forced the great powers to reckon with what happens when you prioritize purity over 
practicality. France and Austria scrambled to fill the power vacuum, while the Habsburg name, once 
synonymous with Europe itself, faded into antique footnotes and haunted portraits. Historians still 
argue whether Charles’s condition was entirely genetic or compounded by illness, but few doubt he 
was the product of an experiment gone too far. His mother, grandmother, great grandmother, and every 
woman before them had been part of the machine, handed off like royal chest pieces in an endless 
cycle of safe marriages. Each one inherited the same traits, passed on the same risks, and prayed 
for a different outcome. None got one. In Charles, we see what happens when those prayers run out. 
Next, we take a breath, one last flicker before the end as we visit the aftermath. What came after 
Charles after the Habsburg fall? What happened to the women who survived the collapse? And how 
did Europe rebuild from the ruins of its most   cursed crown? Now the curtain falls. Charles II 
is gone. The last of the Spanish Hubsburgs buried, embarmed, and left behind in a vault carved 
with the ghosts of his ancestors. You’d think   that would be the end of it. A final period on 
a long tangled sentence that history, especially royal history, doesn’t end neatly. It frays, it 
lingers, it echoes in distant hallways and side branches. Tonight, we trace what came after the 
collapse. What happened to the world those women left behind, the ones who survived the dynasty’s 
fall, the ones married off to clean up the mess, and the new royals who inherited kingdoms and 
bloodlines already soaked in superstition and   genetic fatigue. With Charles II’s death in 1700 
and nowhere to take the throne, Europe did what it does best, panic, negotiate, and go to war. The 
War of the Spanish Succession kicked off almost immediately. It wasn’t just about who got the 
Spanish crown. It was about whether France or Austria were would dominate Europe. The Habsburgs, 
still strong in Austria, backed Archduke Charles, a distant cousin. France pushed forward Philip 
of Anonju, grandson of Louis the 14th, the sun king himself. You already know how this ends. 
Philip wins, but only after 12 years of bloodshed, a continent’s worth of maneuvering and treaties 
so convoluted they make royal marriage charts look   like stick figures. So what happened to the 
women caught in the middle of all this? Many were exiled. Some simply vanished into quieter 
courts. But a few became transitional figures, living links between the old inbred dynasties and 
the new. modernizing powers that would eventually   shake Europe loose from its old obsessions. One 
of the most important of these women was Elizabeth Feneise. Remember her? She was a distant cousin of 
the Habsburgs, married to Philip Fifth of Spain, the first Bourban king of the new regime. 
Elizabeth was clever, calculating, and determined to put her children on as many thrones 
as possible. She understood what her predecessors had ignored that you can’t keep marrying within 
a shrinking circle and expect the tree to grow. So she arranged matches across borders. Naples, 
Palmer, Tuskanyany, expanding influence without relying on cousin to cousin recycling. You could 
argue she helped reboot the Spanish dynasty even as its Habsburg roots were still tangled in 
the floorboards. Elizabeth also cleaned up   after Charles, literally. His court was purged of 
old guards and ghost advisers. She had his former queen, Maria Anna of Noberg, politely removed from 
court and retired to a convent in Toledo, where she lived out her days writing angry letters and 
denying all rumors about her inability to produce   heirs. Maria Anna, to her credit, maintained 
dignity, though it must have been difficult watching her adopted country shift away from the 
world she’d been groomed to rule. And then there   were the Austrian Habsburgs, still reigning in 
Vienna. Maria Terza, born decades after Charles’s death, carried on the name, but not the mistake. 
She married outside the Hapsburg pool, bringing in Francis of Lorraine as her consort, effectively 
ending the most intense cycle of intraf family marriage. Their union produced 16 children, 
including Marie Antuinette, marking a brief return to fertility, vitality, and political savvy. But 
the shadows of the past lingered. The pressure to maintain dynastic integrity was still there, just 
masked in enlightenment trappings and powdered wigs. A quirky and symbolic artifact of this 
shift. In the early 1700s, the Spanish royal court quietly retired the custom of cousin marriage as 
a preferred arrangement. They didn’t abolish it, don’t get too excited, but they began actively 
seeking partners from France, Italy, and those smaller German states. This wasn’t reform driven 
by science. It was driven by trauma. No one wanted that another Charles II. His legacy had become a 
warning whispered through generations. Even so, traces of the old habits lingered. Bourbon France, 
for all its modern pretensions, still allowed first cousin marriages. The British royal family, 
too, kept its bloodline looped tighter than it should have. Queen Victoria’s children would marry 
into nearly every major royal house in Europe, including fatefully the Roman office of Russia, 
spreading hemophilia like a royal calling card. The lesson of the Habsburgs wasn’t ignored. 
Well, exactly. But it wasn’t fully learned   either. And the Habsburg women, the ones who 
came after Charles, they weren’t immune to the old expectations. They were still groomed from 
birth for marriage markets, still photographed   and paraded and whispered about like expensive 
livestock, but their agency slowly increased. Maria Christina of Austria, for example, was 
allowed to marry for love. a scandal at the time and a sign that even the oldest families 
were beginning to unlace their donastic corsets one ribbon at a time. A few decades after 
Charles’s death, portraits of Habsburg women begin to shift. The chins soften, the jaws recede. 
Whether it’s better breeding or better painters, we may never know. But the family face begins 
to fade from the canvas, replaced by powdered cheeks and lighter frames. The architecture of 
a new Europe being built with quieter tools. The scholarly debate continues, of course. Was it 
all about imbreeding? Probably not. The fall of the Spanish Habsburgs was political, economic, and 
military as much as it was genetic. But genetics gave it a face. One that people could point 
to, laugh at, or pity. The women at the heart of that story were never villains. They were 
instruments chosen, trained, married, and bred in service of dynasties that couldn’t admit they 
were breaking under their own weight. And here’s   the final irony. The dynasty that collapsed under 
inbreeding was also the one that left behind the most haunting images of what power really costs. 
Not just in battles and borders, but in lives, in miscarriages, in madness, in the crooked smiles 
of children who couldn’t walk, couldn’t talk, but were still expected to wear crowns. The real 
tragedy wasn’t just the fall. It was how long it took anyone to say, “Maybe we should try something 
different.” Next, we’ll wind down gently, closing the curtains on this sprawling tale, and 
let your mind drift away from court corridors and cousin marriages towards something a little 
quieter, a little softer. You’ve made it. Time to rest. So, here you are. 30 sections, one royal 
bloodline, and several centuries of questionable marriage decisions later. You made it through 
labyrinthine family trees, sagging jaw lines, whispered scandals, stillborn heirs, and dynasties 
that tie themselves into genetic knots with lace trim. Honestly, that’s impressive and probably 
a little concerning. But hey, if you have been lying in bed this whole time, fan humming in 
the background trying to decide whether Joanna   of Castile was really mad or just had the 1500’s 
version of Burnout, then congratulations. You’re exactly the kind of night owl this journey was 
made for. We started with a simple question. How did royal women become the biological architects 
of Europe’s most spectacular dynastic collapses? And it turns out the answer isn’t all that 
simple. Yes, inbreeding played a starring   role. But it wasn’t the only villain. These women 
were born into systems built entirely on control. Control of bloodlines, control of territory, 
control of their very bodies. Whether they were   crowned queens or married off at 15, their lives 
were scripted from birth. their destinies sealed by birthright in a family tree that looked 
more like a spiral staircase. And still, through miscarriages, madness, and the suffocating 
pressure of court life, they showed up. They ruled. They negotiated treaties. They raised 
armies. They educated children. And they wrote letters in 10 languages. Their stories aren’t 
just about decline. They’re about endurance. about what happens when women are expected to hold 
empires together with nothing more than diplomacy,   piety, and a series of increasingly bad 
husbands. Now, as the donastic dust settles, the lights dim behind the velvet curtains, 
and the smell of beeswax and old paper fades. It’s time to drift away. Not into the chaos of 
royal courts or the weight of too many crowns, but into your own quiet space, away from the 
twisted thrones and the pressure of pedigree. You don’t need to carry this lineage any further. 
Let your mind go soft. Let the names fade. Maria Anna, Margaret Traaser, Mariana of Austria. All 
of them slipping away like candle smoke. You’re safe. You’re warm. And you’re definitely not about 
to marry your cousin. Sweet dreams, time traveler.
