12. Pachacuti (1438-1463) He had a vision that convinced him to use warfare to spread Inca culture. By promising peace and gifts, backed by threats, he won many battles. He forced conquered peoples to obey Inca leaders and learn Quechua. Pachacuti allowed the conquered people to keep their native language, leaders, and gods.

13. Topa Inca Yupanqui (1463-1493) He was Pachacuti’s son. He ruled an enormous empire. Yupanqui used innovative techniques to collect taxes.

14. Huayna Capac (1493-1525) He ruled at the high point of the Inca empire. He fathered two sons, Atahualpa and Huascar, who didn’t trust each other. Priests favored Huascar for the next leader and the Army favored Atahualpa. This led to a six year civil war. Atahualpa eventually won, but the wars weakened the Inca empire.

15. Inca Social and Political Organization 3.1C

17. Sapa Inca Sapa Inca was considered a descendant of the Sun God; He ruled by divine right. His subjects were not allowed to look him in the eye nor did he walk as a mortal. He was carried in a golden litter. He married Coya, the empress.

18. Nobles Capac Incas were noble by blood. They controlled land and valuable resources. Their duties included running the government, army, and priesthood. Nobles would become the governors of the f our quarters.

19. Used Quipu to Keep Records Quipu was a method of knotted strings of wool or cotton. This system was used to keep records of numbers of llamas, quantities, of corn, or the number of days commoners worked for the government.

20. Households The empire was divided into households. Every 10 households were governed by the head of one household who reported to the heads of other households. This allowed the Inca to control the economy of diverse communities and collect taxes easily.

21. Laws The state (empire) designated a job for everyone. All had to help with large scale Inca projects, i.e. the army or roads. In addition to working their own land, commoners worked Inca fields and contributed food and cloth to state warehouses.
