November 5, 1768 | Treaty Treaty of Fort Stanwix After expressing their "apprehension" regarding the failure of colonists to strictly observe the 1765 boundary line between Indian Territory and the British colonies, continued negotiations produced this treaty. It describes in detail the line between the Six Nations, tribes of the Ohio, various dependent tribes, and the thirteen seaboard colonies. The agreement effectively closed off legitimate settlement of the Ohio Valley. However, it was ignored by many colonists who migrated west and squatted illegally on Indian lands. The inability of colonial authorities to effectively prevent these illegal settlements west of the boundary aggravated the situation between the various tribes of the region and white settlers along the frontier.
