Under the authority of the 1855 Treaty of Washington, the Rabbit Lake Indian Reservation was established, encompassing an area from where Riverton to Cuyuna are located. After the Dakota War of 1862, majority of the Rabbit Lake Band were removed to the area about Leech Lake and eventually to the White Earth Indian Reservation, and minority of the remaining Rabbit Lake Band members amalgamating with the Mille Lacs Band of Ojibwe to their south. After they were removed there was little settlement in the area until the beginning of a mining village named Cuyuna in 1906. Cuyuna was platted in November 1908.
