The US government and several bands of Ojibwe sign a treaty establishing the Long Prairie Reservation (between the Watab and Crow Wing Rivers) for the Ho-Chunk (Winnebago). Originally from Wisconsin, the Ho-Chunk had been pushed to a reservation in Iowa and then were moved again to Long Prairie. This reservation would not be a good fit, however, and in 1855 they would move to Blue Earth Reservation. Following the US-Dakota War of 1862, they would be forced to move again, this time to a reservation in Dakota Territory.
