The Haudenosaunee, or “people of the longhouse,” commonly referred to as Iroquois or Six Nations, are members of a confederacy of Indigenous nations known as the Haudenosaunee Confederacy. Originally a confederacy of five nations inhabiting the northern part of New York state, the Haudenosaunee consisted of the Seneca, Cayuga, Oneida, Onondaga and Mohawk. When the Tuscarora joined the confederacy early in the 18th century, it became known as the Six Nations.
