Treaty of Greenville Signed Ending Northwest Indian War
Following the American Revolutionary War, conflicts erupted in the Ohio Country as settlers pushed westward into Native lands. The Northwest Indian War pitted a confederacy of tribes against U.S. forces. After the 1794 Battle of Fallen Timbers, leaders including General Anthony Wayne negotiated peace. On August 3, 1795, representatives of the United States and twelve Native nations signed the Treaty of Greenville at Fort Greenville. The agreement ceded vast territories in present-day Ohio and parts of Indiana, Illinois, and Michigan to the U.S. in exchange for annuities and recognition of remaining tribal lands. It opened the region to American settlement.
Why it matters: The treaty secured U.S. control over the Northwest Territory, enabling Ohio's statehood in 1803 and further westward expansion. It established a precedent for federal treaty-making with Native nations that shaped U.S. Indian policy for decades. The land cessions facilitated agricultural development and migration into the Midwest.
