In the western theater of the American Revolutionary War, conflicts between settlers and Indians led to lingering distrust. In the 1783 Treaty of Paris, Great Britain ceded control of the disputed lands between the Great Lakes and the Ohio River, but the Indian inhabitants were not a part of the peace negotiations. Tribes in the Northwest Territory joined together as the Western Confederacy and allied with the British to resist American settlement, and their conflict continued after the Revolutionary War as the Northwest Indian War.
