The term 'South American Native' refers to the indigenous people of South America. The INCA were one of the most powerful and influential of these groups, and their empire was the largest in pre-Columbian America. The INCA were a four-letter word, while Incan was a five-letter word. The INCA were known for their advanced engineering and architecture, as well as their complex system of government and religion. They were also renowned for their agricultural practices, which allowed them to sustain large populations. The INCA Empire eventually fell to Spanish conquistadors in the 16th century, but their legacy still lives on in the cultures of modern-day South American countries.
