At its height the Iroquois Confederacy (or Haudenosaunee) - a union of the Mohawk, Oneida, Onondaga, Cayuga, and Seneca nations - controlled lands from Quebec to Ohio.
Its origin story goes back to the legend of the warrior Hiawatha and the Peacemaker. In the end its system of governance may have been an inspiration for the founding fathers.
Joining Don to explore the history of the Haudenosaunee is Jen Birch, archaeologist at the University of Georgia.
