 The Fair Play Men were illegal settlers (squatters) who established their own system of self-rule from 1773 to 1785 in the West Branch Susquehanna River valley of Pennsylvania in what is now the United States.Because they settled in territory claimed by Native Americans, they had no recourse to the Pennsylvania colonial government.Accordingly, they established what was known as the Fair Play System, with three elected commissioners who ruled on land claims and other issues for the group.
