Broken Promises e Minnesota Dakota and the United States government signed nine treaties between 1805 and 1858, though the Doty Treaty was never ratified. e most influential and well-known are the 1851 Treaties of Traverse des Sioux and Mendota. Unable to pay debts claimed by fur traders, and in perilous economic condition, the Wahpeton and Sisseton Dakota signed a treaty at Traverse des Sioux on July 23, 1851. Dakota leaders agreed to sell their lands west of the Mississippi to the United States, in exchange for $1,665,000 and a permanent home ten miles on either side of the Minnesota River, from present-day New Ulm to Lake Traverse. Meanwhile, representatives from the Mdewakanton and Wahpekute tribes reluctantly signed their lands away in Mendota for $1,410,000 on August 5. e treaties created the Upper Sioux and Lower Sioux reservations, and opened 24 million acres to newcomers. In addition to the treaties, Dakota leaders were deceived into signing a document referred to as the “traders’ papers.” ese illegal papers redirected the money they were promised for their land to traders. e 1851 treaties were ratified by the U.S. Senate without a “Father, now guarantee of the reservation in when I sign perpetuity. Such deceit and broken this paper and promises increased tensions among the Dakota, traders, you go to Washington and U.S. government. with it, I want you courtesy of the Minnesota Historical Society to see all that is Territory Ceded by the 1851 Dakota Treaties Dakota Reservations on the Upper Minnesota River written here fulfilled.” ~ Wee-tehan-h’pee-ee-tay-toan, 1851 “Father, you think it a great deal you are giving for this country. I don’t think so, for both our lands and all we get from them will at last belong to the white man.” ~ Oo-pee-ya-hen-day-a, 1851 051020 40 60 Maps created by Eric C.
