On February 15, 1837, Congress ratifies treaties number 211 and 217, designed to remove Indigenous people from their ancestral homelands in the Midwest to make way for white settlement. One agreement had been negotiated with the Iowa, Sauk and Fox nations; the second, with the Oto, Omaha, Missouri and Santee Sioux and Yankton Sioux tribal people. The agreements represented just two of nearly 400 treaties—nearly always unequal—concluded between various Indigenous nations and the U.S. government between 1788 and 1883.
