The Treaty of Easton was a colonial agreement in North America signed in October 1758 during the French and Indian War (Seven Years War). Briefly, chiefs of 13 Native American nations, representing tribes of the Iroquois, Lenape-Delaware, Shawnee and others, agreed to be allies of the British colonies during the French and Indian War (Seven Years War), already underway. In return the governments of Pennsylvania and New Jersey recognized Native rights to hunting grounds in the Ohio Valley and settlements in the Ohio Country. They promised not to establish additional settlements west of the Appalachian Mountains.
