Many Native Americans moved to different regions in the continent and as time passed, different tribes had their own culture. When Columbus came to America, America was divided into three areas, namely: North, Central, and South America.
In North America, i.e. the Crow and Cheyenne, were true hunters, while the Sioux did farming alongside with hunting.
In Central America, the Aztecs and the Mayas settled in these lands. The Aztecs were merciless since there was a chance that they would sacrifice you to their gods if you were their prisoner. The Aztec’s buildings were enormous, that even the Europeans were impressed by it.
In South America, the Inca people did a lot of farming since most of them are farmers. Farming was their main source of food and eventually, they began expanding and was able to build an empire.
