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.hupa Inka Yupanki (also known as Topa Inca), Pachakuti's successor from 1471 CE, is credited with having expanded the empire by a massive 4,000 km (2,500 miles). The Incas themselves called their empire Tawantinsuyo (or Tahuantinsuyu) meaning 'Land of the Four Quarters' or 'The Four Parts Together'.
Rich in foodstuffs, textiles, gold, and coca, the Inca were masters of city building but nevertheless had no money. In fact, they had no marketplaces at all. In the fifteenth and sixteenth centuries, the Inca Empire was the largest South America had ever known. Centered in Peru, it stretched across the Andes' mountain tops and down to the shoreline, incorporating lands from today's Colombia, Chile, Bolivia, Ecuador, Argentina and Peru - all connected by a vast highway system whose complexity rivaled any in the Old World.
