This is the result of 200 years of inbreeding, Charles the II of Spain, at age 4 he could barely walk and was still breastfeeding. At age 9 he couldn't read or write, he died at age 38 and his death led to the War of the Spanish Succession killing between 400k and 700k people.

The Habsburgs were amateurs compared to the ancient Egyptians when it came to competitive incest. Pharaohs didn't dick around with cousin marriage, pairing off with their siblings instead. Which is how you get someone like the Pharoah Tutankhamun, better known as King Tut. As famous as his name is, most people don't realize that he was an walking abomination against nature.

Tut couldn't walk due to Kohler's disease, a condition which makes the bones in your feet die, resulting in your feet collapsing into fleshy blobs and making any attempt at walking immensely painful. He also had an absurd overbite, a cleft palate, a bent spine, and feminine hips. He would've struggled to even move his head due to fused vertebrae in his neck, requiring him to turn his whole body to look at something.

He died at the ripe old age of 18, having lived 18 years longer than he had any right to or probably even wanted to.
