Dobyns Henry F. The Papago People

Phoenix: Indian Tribal Series, 1972. — 106 p.The Tohono O’odham are a Native American people of the Sonoran Desert, residing primarily in the U.S. state of Arizona and the Mexican state of Sonora. Tohono O’odham means "Desert People." The Tohono O’odham tribal government and most of the people have rejected the customary English name Papago, used by Europeans after being adopted by Spanish conquistadores from hearing other Piman bands call them this. The Tohono O'odham Nation, or Tohono O'odham Indian Reservation, is a major reservation located in southern Arizona, encompassing portions of Pima County, Pinal County, and Maricopa County.
The Tohono O’odham share linguistic and cultural roots with the closely related Akimel O'odham (People of the River), whose lands lie just south of present-day Phoenix, along the lower Gila River. The Sobaipuri are ancestors to both the Tohono O’odham and the Akimel O’odham, and they resided along the major rivers of southern Arizona.
