Step-by-step explanation:
After the American Revolution, Native nations between the Mississippi River and the western border of the United States struggled to hold onto their land and independence. Many tribes, such as the Mohawk, Cayuga, Onondaga, Seneca, and Shawnee, fought on the British side, while others, like the Oneida and Tuscarora, supported the American revolutionaries.
The Revolution was a contest for Indian lands, and the majority of Indians fought for the British cause as it provided some degree of security against American expansion.
