Twantinsuyu: World of the Incas
lDuring the period following the disintegration of the states of Tihuanaco and Huari (c.550-1000 C.E.) smaller regional states exercised power in the Andes. lSome of them were centers of agricultural activity and population density. lThe considerable warfare among the states resembled the post-Toltec period in Mesoamerica. lThe state of Chimor (900-1465) emerged as most powerful, controlling most of the north coast of Peru.
lAfter 1300 the Inca developed a new civilization.
