O'odham

The O'odham, Upper Oʼodham, or Upper Pima (Spanish: Pima Alto or Piatos) are a group of Native American peoples including the Akimel O'odham, the Tohono Oʼodham, and the Hia C-eḍ Oʼodham. Their historical territory is in the Sonoran desert in southern and central Arizona and northern Sonora, and they are united by a common heritage language, the O'odham language. Today, many O'odham live in the Tohono O'odham Nation, the San Xavier Indian Reservation, the Gila River Indian Community, the Salt River Pima-Maricopa Indian Community, the Ak-Chin Indian Community or off-reservation in one of the cities or towns of Arizona.

History
Most archaeologists believe the Oʼodham to be descended from the Hohokam, although some argue that one group invaded the other's territory.

Language
The O'odham language, variously called O'odham ñeʼokĭ, O'odham ñiʼokĭ or Oʼotham ñiok, is spoken by all O'odham groups. There are certain dialectal differences, but they are mutually intelligible and all O'odham groups can understand one another. Lexicographical differences have arisen among the different groups, especially in reference to newer technologies and innovations.

Oʼodham sub-groups
The Pima Alto or Upper Pima groups were subdivided by scholars on the basis of cultural, economic and linguistic differences into two main groupings:

One was known commonly as the Pima or River Pima. Since the late 20th century, they have been called by their own name, or endonym: Akimel Oʼotham
 * Akimel O'odham (Akimel Au-Authm, meaning "River People", often simply called Pima, by outsiders, lived north of and along the Gila, the Salt, and the Santa Cruz rivers in what is today defined as Arizona)
 * On'k Akimel O'odham (On'k Akimel Au-Authm – "Salt River People," lived and farmed along the Salt River), now included in the Salt River Indian Reservation.
 * Keli Akimel O'otham (Keli Akimel Au-Authm, oft simply Akimel O'odham – "Gila River People", lived and farmed along the Gila River), now known as the Gila River Indian Community (GRIC)
 * Ak-Chin O'odham (Ak-Chin Au-Authm), Ak-Chin Indian Community
 * Sobaipuri, (also simply called Sobas, called by the neighboring Akimel O'odham as Ṣáṣavino – "spotted"), originally lived in the valleys of the San Pedro River and Upper Santa Cruz River. In the early 18th century, they were gradually driven out of the lower San Pedro River valley. In the middle of the century, their remaining settlements along the upper San Pedro River were broken up by Arivaipa and Pinaleño Apache attacks. They moved west, seeking refuge among the Tohono O'odham and Akimel O'odham, with whom they merged.

The other peoples are the Tohono O'odham or Desert Pima, enrolled in the Tohono O'odham Nation.
 * Tohono O'odham ("Desert People"); the neighboring Akimel O'odham called them Pahpah Au-Authm or Ba꞉bawĭkoʼa – "eating tepary beans", which was pronounced Papago by the Spanish. They lived in the semi-arid deserts and mountains south of present-day Tucson, Tubac, and south of the Gila River
 * Kuitatk (kúí tátk)
 * Sikorhimat (sikol himadk)
 * Wahw Kihk (wáw kéˑkk)
 * San Pedro (wiwpul)
 * Tciaur (jiawul dáhăk)
 * Anegam (ʔáˑngam – "desert willow")
 * Imkah (ʔiˑmiga)
 * Tecolote (kolóˑdi, also cú´kud kúhūk)
 * Hia C-eḍ O'odham ("Sand Dune People", also known by the neighboring O'odham as Hia Tadk Ku꞉mdam – "Sand Root Crushers," commonly known as "Sand Pimas," lived west and southwest of the Tohono O'odham in the Gran Desierto de Altar of the Sonoran Desert between the Ajo Range, the Gila River, the Colorado River and the Gulf of California south into northwestern Sonora, Mexico. There they were known to the Tohono O'odham as Uʼuva꞉k or Uʼuv Oopad, named after the Tinajas Altas Mountains.)
 * Areneños Pinacateños or Pinacateños (lived in the Sierra Pinacate, known as Cuk Do'ag by the Hia C-eḍ O'odham in the Cabeza Prieta Mountains in Arizona and Sonora)
 * Areneños (lived in the Gran Desierto around the mountains, which were home to the Areneños Pinacateños)
