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.
