Anthropology Archaeology Biology Cultures ... Help Between 1200 and 1535 AD, the Inca population lived in the part of South America extending from the Equator to the Pacific coast of Chile. The beginning of the Inca rule started with the conquest of the Moche Culture in Peru. The Inca were warriors with a strong and powerful army. Because of the fierceness of their army and their hierarchical organization, they became the largest Native American society. The height of their reign in the 15th century came to a brutal end in 1535 when the Spanish conquistadors took over their territory. Their cities and fortresses were mostly built on highlands and on the steep slopes of the Andes Mountains. The architecture of the Inca cities still amazes and puzzles most scientists. Stone steps lead up to the top of the cities, which consist of stone houses and religious buildings. The blocks of stones weigh several tons and they are fit together so tightly that not even a razor blade can fit through them. The central city was mainly used for government purposes, while the citizens occupied surrounding areas. Their homes were made from the same stone material and had grass rooftops.
