Topa Inca Yupanqui was the second Sapa Inca (1471-93) of the Inca Empire, fifth of the Hanan dynasty, and tenth of the Inca civilization. His father was Pachacuti, and his son was Huayna Capac. Topa Inca belonged to the Qhapaq panaca (one of the clans of Inca nobles). He conquered Chimor, which occupied the northern coast of what is now Peru, the largest remaining rival to the Incas. He conquered the province of Antis and subdued the Collas. He imposed rules and taxes, creating two Governor Generals, Suyuyoc Apu, one in Xauxa and the other in Tiahuanacu. Tupac Inca Yupanqui created the fortress Saksaywaman on the high plateau above Cuzco, which included store houses for provisions and clothing. Tupac Inca died in 1493, leaving two legitimate sons, and 90 illegitimate sons and daughters.
