Inca Society Interactive Mind Map
The society of the Inca Empire centered in what is now Peru, from AD 1438 to AD 1533. Over that period, the Inca used conquest and peaceful assimilation to incorporate in their empire a large portion of western South America, centered on the Andean mountain ranges. The Inca empire proved short-lived: by AD 1533, Atahualpa, the last Inca emperor, called Sapa Inca, was killed on the orders of the conquistador Francisco Pizarro, marking the beginning of Spanish rule.
