Rajah Humabon

Rajah Humabon, baptized as Carlos, was a Filipino ruler who was one of the recorded chiefs in the historic polity of Cebu who encountered Ferdinand Magellan in 1521. Humabon, his wife whose original name is unknown but was baptized as Juana, and his subjects were the first known Christian converts in the Philippines. Humabon is also considered the "first Filipino traitor" due to his politicking to force Magellan to subdue neighboring Mactan chief Lapulapu, and Humabon's subsequent massacre of the surviving Spaniards and crewmen.
