Inca Civilization. Definition. The Inca civilization flourished in ancient Peru between c. 1400 and 1533 CE, and their empire eventually extended across western South America from Quito in the north to Santiago in the south, making it the largest empire ever seen in the Americas and the largest in the world at that time.
The Inca Empire, also known as the Incan Empire and the Inka Empire, was the largest empire in pre-Columbian America, and possibly the largest empire in the world in the early 16th century. Its political and administrative structure was the most sophisticated found among native peoples in the Americas. The administrative, political and military center of the empire was located in Cusco in modern-day Peru. The Inca civilization arose from the highlands of Peru sometime in the early 13th century
