late Intermediate Period
General term referring to the fifth of the seven main chronological phases recognized in Andean archaeology, broadly the period c.ad 1000 to 1450. It follows the collapse of middle Horizon empires such as the Tiahuanaco and Huari, during which distinctive regional cultures emerged along the coast and in highland areas. The most extensive of these was the Chimú Culture. The various polities that developed during the late Intermediate Period were subsequently conquered by the Inca Empire.
