Iroquois

n. group of American Indian peoples which originally inhabited the Hudson River Valley of the United States (includes the Cayuga, Mohawk, Oneida, Seneca, and Onondaga tribes); member of one of the Iroquois tribes

The Iroquois Confederacy (also known as the "League of Peace and Power", the "Five Nations"; the "Six Nations"; or the "People of the Long house") is a group of First Nations/Native Americans that originally consisted of five nations: the Mohawk, the Oneida, the Onondaga, the Cayuga, and the Seneca. A sixth tribe, the Tuscarora, joined after the original five nations were formed. Although frequently referred to as the Iroquois, the Nations refer to themselves collectively as Haudenosaunee.
