According to Disney, princes are the most charming, handsome men in all the land. Historically, that's far from the truth. Royal families were typically pretty obsessed with power. No matter how much they had, they wanted more, and they wanted to keep it. One way to do that was by keeping it in the family; AKA, they slept with their cousins. Back then, incest wasn't so taboo. Marriages between uncles and nieces and other close relations happened frequently.
Unfortunately, it wasn't just power that was passed down to future generations. Genetic disorders that were uncommon among the general population were condensed in royal bloodlines to the point that sickness was as much of a royal inheritance as wealth. The result? A ton of really weird royals, including the infamous Henry VIII who was known for his paranoia and tyrannical behavior. Keep scrolling to discover all the strange effects that inbreeding had on the royal families of yesteryear.
The Habsburg Jaw
The German-Austrian Habsburg family had an empire encompassing everything from Portugal to Transylvania, partially because they married strategically to consolidate their bloodline. Because of their rampant incest, the Habsburgs accidentally created their own trademark facial deformities, collectively known as the Habsburg jaw. Those who inherited the deformity typically had oversized jaws and lower lips, long noses, and large tongues. It was most prevalent in male monarchs, with female family members experiencing fewer external deformities. Charles II had such a severe case that he had trouble speaking and frequently drooled...yikes.
For most people, cuts and bruises are no big deal. For those with hemophilia, a scraped knee can turn serious. Hemophilia is a rare blood disorder in which your body doesn't produce enough clotting factor. When someone with hemophilia starts to bleed, they don't stop. The disease is recessive, so it's very uncommon; both of your parents must carry the gene for you to develop symptoms. Unfortunately, it was easy for inbred royals to produce unfortunate gene combinations.
Queen Victoria and her husband, Prince Consort Albert, both carried the gene for hemophilia, as they were first cousins. Their son, Leopold, struggled with the disease until it eventually killed him when he was only 31. Hemophilia was passed down to Russian Czar Nicholas II's family. His son and heir, Alexei, suffered from hemophilia, inherited from his great-grandmother, Queen Victoria. Even in the early 1900s, the life expectancy of someone with hemophilia was only about 13 years.
Spanish royalty was particularly prone to the genetic condition of hydrocephalus, in which fluid builds up deep in the brain. The extra fluid puts pressure on the brain and spinal cord, causing everything from mild symptoms to death. It occurs most frequently in infants, which was often the case in inbred royalty. The royal children who suffered from it were born with abnormally large heads and often suffered from growth delays, malnourishment, muscular atrophy, poor balance, and seizures.
Hydrocephalus also affected British royalty, including Prince William, the oldest surviving child of Queen Anne and Prince Consort George of Denmark. The two royals were cousins, and they were so genetically similar that they struggled to reproduce any healthy offspring, losing 17 children to genetic disease. You'd think they'd figure it out after the first few, but they were determined to produce an heir. Prince William made it until age 11, when he died of hydrocephalus combined with a bacterial infection.
Royal inbreeding existed before the European monarchy was even a thing. Ancient Egyptians practiced marriage within the royal family with the intent of keeping their bloodline pure, and it backfired big time. King Tutenkhamen, AKA King Tut, was one of Egypts most famous pharaohs, but he was a bit of a genetic mess. Modern-day studies showed that he had a cleft palate, a club foot, and a strangely elongated skull. Some researchers believe King Tut's mother wasn't really Queen Nefertiti, but King Akhenaten's sister. Sibling-sibling inbreeding tends to have severe effects, giving poor King Tut a compromised immune system that led to his eventual death.
King Charles II married twice, yet he never successfully fathered an heir. Like many other royals, he struggled with fertility, likely the result of his inbred heritage. Queen Anne, the first monarch of Great Britain, was a great ruler, but not so great at producing healthy children. Only one of 18 of her offspring made it past their toddler years, with eight miscarried and five stillborn. Considering the great pressure to produce heirs to inherit the throne, infertility caused a great deal of royal strife. In some ways, however, it was a boon. Since Charles II never had children, his laundry list of genetic issues, including the infamous Habsburg jaw, died with him.
Speaking of Charles II, he didn't say a word until he was four and didn't learn how to walk until he was eight. He was the child of Philip IV of Spain and Mariana of Austria, who were uncle and niece. His family's long history of inbreeding was so severe that he was more severely inbred than he would have been had his parents been siblings. While inbreeding doesn't automatically lower intelligence, it does make it more likely to inherit recessive genes linked to low IQ and cognitive disabilities, resulting in a royal family with just as many mental challenges as physical ones.
George III was King of England at the time of the American Revolution, and many wonder if his mental illness had something to do with his failure as a ruler. Another member of Queen Victoria's highly inbred family, George III was known for his manic episodes and nickname of "The Mad King". Initially, historians believed that he had porphyria, a chronic liver disease that results in bouts of madness and causes bluish urine. Today, it's believed that George III actually suffered from bipolar disorder, causing his sudden manic episodes and rash decision making.
Other royals suffered from mental illness as well, including Queen Maria the Pious. She was so obsessively devout that when her church's confessor died, she screamed for hours about how she would be damned without him. She shared a doctor with King George III, who employed all kinds of strange and ineffective treatments, like ice baths and taking laxatives.
Joanna of Castile, also known as Joanna the Mad, also struggled with irrational behavior and uncontrollable moods. Like most women, she was furious when she discovered her husband's mistress. Unlike most people, she proceeded to stab her in the face. She remained obsessed with her husband after his infidelity, however. She loved him so much that she slept beside him even after he died. You read that right. She snuggled a corpse. M'kay then.
Monarchs have a reputation for reckless, harsh, and sometimes cruel behavior. Is it possible that many of their worst deeds were tied to inbred insanity? Totally. Does that make their tyrannical reign any less terrifying? Not even a little bit. While their stories are fascinating to read about, let's keep the inbreeding and dictatorships in the history books, okay? Okay.
