The last ruler of the Inca empire, son of Huayna Capac. Ruling from 1525 in Quito (now in Ecuador), he defeated Huáscar, his half‐brother and co‐ruler in Cuzco, whom he killed after the battle of Huancavelica in 1530. In 1532 he marched against Francisco Pizarro and remnants of the Huáscar faction, who had allied themselves to the Spaniards; at Cajamarca he was drawn into an ambush, captured, and held for ransom. He ordered a room to be filled with gold and silver objects while another army secretly marched to free him, but was murdered when Pizarro learned of the plan. Shortly thereafter Pizarro captured Cuzco and within a few years Spain ruled the lands of the Incas.
