Cuitláhuac, 10th tlatoani of the Aztec Empire, brother of Moctezuma II. After being held captive by the Aztecs, Cortés ordered Moctezuma to ask his people stop fighting. Moctezuma told him that they wouldn't listen to him, and in turn asked him to free his brother Cuitláhuac so he'd convince the people to stop. Once freed, Cuitláhuac led his people against the conquistadors and successfully drove them out of Tenochtitlán on June 30, 1520. After ruling for only 80 days, he died of smallpox.
