Treaty with the Grand Pawnee, 1818

The Treaty with the Pawnee of 1818 was signed on June 18, 1818 between the United States and the Grand Pawnee tribe. Its main purpose was to establish perpetual peace and friendship between the U.S. and the Pawnee tribe. The Pawnee chiefs placed their tribe under the protection of the United States and no other sovereign power. They agreed to deliver up any individuals who violated the treaty’s terms to be punished under U.S. law. The treaty served to formally align the Pawnee tribe with the United States after the War of 1812.
