Portrait of Túpac Amaru, the last Sapa Inca. In 1533, after the death of Atahualpa, Atahualpa’s brother, Manco Inca Yupanqui, was crowned Emperor by the Spaniards. In 1536, he revolted, gathered troops, and marched on the city of Cuzco and besieged it. The revolt was only partially successful, and he fled to the remote city of Vilcabamba where he continued to rule as Sapa Inca of a “post-Inca” or “neo-Inca” state. He was succeeded by his three sons, of whom Túpac Amaru was the last. Túpac Amaru was captured and executed by the Spanish in 1572, bringing the Inca Empire to a permanent end.
