The Iroquois Tribes, also known as the Haudenosaunee, are a group of Native American nations originally from the northeastern United States and southeastern Canada. The main tribes include the Mohawk, Oneida, Onondaga, Cayuga, Seneca, and Tuscarora. They are known for their sophisticated political system, which includes a council of chiefs representing each tribe. The Iroquois are famous for their longhouses, which served as communal living spaces for extended families. They played a significant role in early American history, particularly during the French and Indian War and the American Revolution, where their alliances influenced the outcomes of various conflicts.
