The Inca Empire (or Inka Empire) was the largest empire in pre-Columbian America. The aministrative, political and military center of the empire was located in Cusco. The Inca Empire arose from the highlands of Peru sometime in early 13th century. From 1438 to 1533, the Incas used a variety of methods, from conquest to peaceful assimilation, to incorporate a large portion of western South America, centered on the Andean mountain ranges, including large parts of modern Ecuador, Peru, western and south central Bolivia, northwest Argentina, north and north-central Chile, and southern Colombia. The Incas identified their king as "child of the sun."
