There were about two million Native Americans in North America in the fifteenth century when the Europeans arrived. They belonged to 300 different groups and spoke more than 2,000 different languages. Sadly, the Europeans fought and killed many Native Americans and also brought diseases which killed them. The film The Last of the Mohicans, from the book by James Fenimore Cooper, shows the sad end of a group of Native Americans in the eighteenth century. The Native Americans that we know as 'Indians' in cowboy films lived in the West. They were the Cheyenne, the Blackfoot, and the Sioux (also known as Lakota), for example.
