Charles Marion Russell, also known as C. M. Russell, Charlie Russell, and "Kid" Russell, was an American artist of the American Old West. He created more than 2,000 paintings of cowboys, Native Americans, and landscapes set in the western United States and in Alberta, Canada, in addition to bronze sculptures. He is known as "the cowboy artist" and was also a storyteller and author. He became an advocate for Native Americans in the west, supporting the bid by landless Chippewa to have a reservation established for them in Montana. In 1916, Congress passed legislation to create the Rocky Boy Reservation.

Rocky Boy's Indian Reservation is one of seven Native American reservations in the U.S. state of Montana. Established by an act of Congress on September 7, 1916, it was named after Ahsiniiwin, the chief of the Chippewa band, who had died a few months earlier. It was established for landless Chippewa (Ojibwe) Indians in the American West, but within a short period of time many Cree (Nēhiyaw) and Métis were also settled there. Today the Cree outnumber the Chippewa on the reservation. The Bureau of Indian Affairs (BIA) recognizes it as the Chippewa Cree Reservation.
