This Inbred Spanish King Was “So Ugly” That He Scared His Own Wife

Charles II's family was so set on keeping the royal bloodline that they put their children at risk just to make sure outsiders stayed outsiders.

King Charles (Carlos) II of Spain was the last Habsburg ruler of Spain — and thankfully so. He was tragically ugly through no fault of his own, but due to the desire of his family to maintain their bloodline.

Charles II of Spain was born November 6, 1661, and became king in 1665 at the tender young age of four. His mother ruled as a regent for 10 years until Charles was a teenager.

Charles was born into political strife in Europe as the Habsburgs tried to control the entire continent.

You see, the Habsburgs came from Austria, and they had designs on the French throne. The Habsburgs ruled The Netherlands, Belgium, and parts of Germany but unfortunately, Charles II was too ugly, too deformed, and too intellectually stunted to rule Spain and its neighbors properly.

That’s what happens after 16 generations of inbreeding.

Keeping It In The Family

The Habsburgs were so bent on keeping power, as they had for a few hundred years, that they often married their own blood relatives. After 16 generations of this, Charles II’s family was so inbred that his grandmother and his aunt were the same person.

Do you feel sorry for Charles II yet?

It gets worse.

Charles II’s most prominent feature was his jaw, known as the Habsburg jaw, that identified him as part of his royal family. His two rows of teeth could not meet.

The king was unable to chew his food. Charles II’s tongue was so huge he could barely speak. He was not allowed to walk until he was almost fully grown and his family didn’t bother to educate him. The king was illiterate and totally dependent on those around him.

Charles II Of Spain’s Marriages

His first wife, Marie Louise of Orleans (Charles II’s second niece), came from an arranged marriage. The French ambassador wrote to the Spanish court in 1679 that Marie wanted absolutely nothing to do with Charles, saying that “The Catholic King is so ugly as to cause fear and he looks ill.”

The ambassador was 100 percent correct.

Charles II of Spain could barely walk because his legs could not support his weight. He fell several times. Marie died in 1689 without producing an heir for Charles II. The Spanish monarch was depressed after his first wife died.

Depression was a common trait among the Habsburgs. So was gout, dropsy, and epilepsy. The lower jaw was the kicker, though, as it made Charles II seem stunted. His ministers and advisers suggested the next move in Charles II of Spain’s reign: to marry a second wife.

His second marriage was to Marie-Anne of Neubourg, and it happened mere weeks after his first wife died. Marie-Anne’s parents had 23 children, so surely Charles II would have at least one child with her, right?


Charles II of Spain was impotent and could not father children. It was part of his family legacy of inbreeding. He probably suffered from two genetic disorders.

First, there was combined pituitary hormone deficiency, a disorder that made him short, impotent, infertile, weak, and have a host of digestive problems. The other disorder was distal renal tubular acidosis, a condition marked by blood in the urine, weak muscles, and having an abnormally large head compared to the rest of the body.

Charles II’s ugliness and health problems weren’t due to anything he did. Generations of his family’s inbreeding were to blame.

The irony of the situation is that the Habsburgs felt as if their line would only survive if they married only people who were of royal blood. This very same thought led to at least two centuries of inbreeding that finally failed to produce an heir to the throne.

Charles II of Spain died (mercifully) in 1700 at the age of 39. Because he had no children, his death caused a 12-year war in Europe known as the War of Spanish Succession. The Habsburgs’ reign was over.
