During their history, the Crow have changed their territory many times because of conflicts with the Ojibwe, Cree, Cheyennes, and Lakota (Sioux) peoples. They were generally friendly with the whites. Since the 19th century, most Crow people have lived on their reservation that is south of Billings, Montana. Although they have lost land, it is over 9300 km. They also live in several major western cities. The tribe's headquarters are located at Crow Agency, Montana.
