South American Natives refers to the indigenous people of South America. The Incas were one of the most powerful and influential pre-Columbian civilizations in South America, with their empire stretching from modern-day Ecuador to Chile. The Incas were a highly organized society that developed advanced agricultural techniques, built impressive stone structures, and created a complex system of government. The INCA Empire was ruled by an emperor known as the Sapa INCA, who was believed to be descended from the sun god Inti. The Incas also had a complex religious system that included human sacrifice. The Incas were eventually conquered by the Spanish in the 16th century. The term 'INCA' is still used today to refer to the descendants of the INCA Empire.
