During the late 19^th and early 20^th centuries, the Office of Indian Affairs (OIA) made many attempts to educate Native Americans in American culture.  The Office established schools on reservations, in and around the military forts near the reservations, and in some cases, Indian students were sent to all white schools off the reservation.  This integration took its toll on many Native Americans through assimilation, for OIA policy was to get rid of traditional Native American culture.
