Treaty of Wapakoneta
The Treaty of Wapakoneta was signed on August 8, 1831. Remnants of the Shawnee Native American tribe in Wapakoneta were forced to relinquish claims that they had to land in western Ohio.
In exchange, the United States government agreed to provide the tribe with 100,000 acres (400 km²) of land west of the Mississippi River. The United States officials agreed to provide supplies and monetary payment and to construct a sawmill and a gristmill for the Shawnees on their newly allocated land.
