Inca civilization was one of the most prominent civilizations in prehispanic South America. It was located in the Andes Mountain, in Peru. It was the larger empire before the arrival of Christopher Columbus to America. It had its best years from 1400 to 1533. The most important city was Machu Picchu, at the top of the Andes. The Inca Ruler was the most important figure of the empire.
