Iroquois Confederacy

The Iroquois Confederacy (Haudenosaunee, or League of Peace and Power) was a sophisticated political alliance of initially five — later six — Indigenous nations: the Mohawk, Oneida, Onondaga, Cayuga, Seneca, and (after 1722) Tuscarora. One of the most powerful Indigenous confederacies in northeastern North America, it played a decisive role in the colonial wars of the 17th and 18th centuries, including the Seven Years War and the American Revolution. The Confederacy fractured during the Revolution: the Oneida and Tuscarora generally supported the Americans, while the Mohawk, Onondaga, Cayuga, and Seneca allied with Britain. The Sullivan–Clinton Campaign of 1779 devastated Iroquois villages, and the Treaty of Paris (1783) ceded Iroquois lands to the United States without consultation, effectively ending the Confederacy as a geopolitical force.
