The West Virginia. Cyclopedia
The Iroquois Confederacy was an alliance of five Iroquois-speaking nations, the Mohawk, Oneida, Onondaga, Cayuga, and Seneca, formed in present-day New York in the late 1500s. The Tuscaroras joined the Iroquois Confederacy in 1722, and the alliance then became known as the Six Nations.

Treaties with the Six Nations
Treaty of Albany (1722) -- Restricted Iroquois to areas west of the Blue Ridge Mountains.
