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