Historical Note

This Treaty of St. Mary's was signed on October 6, 1818, in Saint Mary's, Ohio, between representatives of the United States government and the Miami tribe (Myaamiaki), as well as other American territorial leaders. This treaty was drafted specifically with leaders from the Miami nation as part of a large-scale effort by the United States to remove indigenous peoples by purchasing their lands and forcibly relocating them, sometimes using military troops, to lands deemed less desirable west of the Mississippi River until the next time.

The Myaamiaki occupied territory that is now known as north and central Indiana, southwest Michigan, and western Ohio. Most Miami people were forced to relocate to Indian Territory (first Kansas, then Oklahoma) by 1846. However, unlike the Potawatomi nation, some Miami families were able to remain in Indiana on reserves granted to individuals, including chiefs Jean Baptiste Richardville (Peshewa) and Francis Godfroy (Palawonza). The Miami Tribe of Oklahoma are the only Miami tribe officially recognized by the United States government. The Miami Nation of Indiana, a nonprofit organization of comprised of the Miami descendants exempted from removal have been unsuccesful in attaining separate recognition, though many were allowed to join the main tribe as of 1996.
