Treaty with the Potawatomi 
On July 18, 1815, the Potawatomi entered into a treaty with the United States at Portage des Sioux, Missouri. The treaty was a means to affirm previous compacts and ultimately draw peace between the Potawatomi Nation and the United States, resulting from the depredations caused and faced by both sides during the War of 1812.
