Treaty of January 9, 1789 – Six Nations
On January 9, 1789, a treaty was established at Fort Harmar between Arthur St. Clair and the Six Nations, reaffirming peace and defining territorial boundaries. The treaty confirmed a boundary line that ceded lands west of it to the United States while securing lands to the east for the Six Nations, alongside a provision for peace and mutual protection. It further ensured that the Oneida and Tuscarora nations retained their territories and addressed matters of justice for crimes committed across the boundary.
