The Iroquois Confederacy consisted of five, later six, tribes, speaking the Iroquois language. In addition to these tribes there were others belonging to the same linguistic stock, such as the Hurons, the Cherokee, and others. The Confederacy or League of the Iroquois was formed towards the end of the sixteenth century and embraced, at that time, the following tribes: Mohawk, Oneida, Onondaga, Cayuga and Seneca. In the beginning of the eighteenth century they were joined by the Tuscarora.
