Native American tribes.
The Iroquois Nation is a group of six Native American tribes (the Cayuga, Mohawk, Onondaga, Oneida, Seneca, and Tuscarora) that have live together under one law in New York State for hundreds of year. James Fenimore Cooper wrote about these warriors in his famous book, the last of the Mohicans.(A Mohican is a person in the Mohawk tribe.)
The Lakota Sioux tribe live in the area that is now Minnesota, Wisconsin, North and South Dakota, and part of Nebraska. In the past they had lived near the Great Lakes further east, but as more European settlers arrived, they had to move west. There are seven Sioux tribes in total.
