Tucson Indian School

Like many other places in the American west, Tucson had an Indian Boarding school. These schools have become very controversial today but were thought of as beneficial for their students and for the survival of Indian tribes. By design, they had a destructive impact on native American cultures. An extensive photograph collection can be seen on the Arizona Memory Project site. 

This is the lead paragraph of a Wikipedia article: 

Tucson Indian school was founded by the United States federal government in 1888 to assimilate Native American children of the Akimel O'odham and Tohono Oʼodham tribes from the area around what is now Tucson, Arizona into mainstream American society. The school was created under federal acts with the goal of indoctrinating Native American children into Western colonial society by separating them from their communities' culture and reeducating them in boarding schools. The school closed in the 1950s.
