Charles II

Charles II, otherwise known as El Hechizado (The Hexed) or The Bewitched. Was the final Habsburg ruler of Spain, best known for his physical and mental disabilities. Most notably his face. Believed to be caused by the past 16 generations of inbreeding, he was also incapable of knocking up his two mistresses and died heirless in 1700. Beginning the war of the Spanish Succession, don't knock up your niece/uncle kids.
