Inca rule in Chile was brief; it lasted from the 1470s to the 1530s when the Inca Empire was absorbed by Spain. The main settlements of the Inca Empire in Chile lay along the Aconcagua, Mapocho and Maipo rivers. Quillota in Aconcagua Valley was likely the Incas' foremost settlement. The bulk of the people conquered by the Incas in Central Chile were Diaguitas and part of the Promaucae (also called Picunches).
