Apache is the collective name for several culturally related groups of Native Americans in the United States. These indigenous peoples of North America speak a Southern Athabaskan (Apachean) language, and are related linguistically to the Athabaskan speakers of Alaska and western Canada. The modern term Apache excludes the related Navajo people. However, the Navajo and the other Apache groups are clearly related through culture and language and thus are considered Apachean. Apachean peoples formerly ranged over eastern Arizona, northwestern Mexico, New Mexico, parts of Texas, and a small group on the plains. There was little political unity among the Apachean groups. The groups spoke 7 different languages. The current division of Apachean groups includes the Navajo, Western Apache, Chiricahua, Mescalero, Jicarilla, Lipan, and Plains Apache (formerly Kiowa-Apache). Apache groups are now in Oklahoma and Texas and on reservations in Arizona and New Mexico. The Navajo reside on a large reservation in the United States. Some Apacheans have moved to large metropolitan areas, such as New York City. The Apachean tribes were historically very powerful, constantly at enmity with the Spaniards and Mexicans for centuries. The first Apache raids on Sonora appear to have taken place during the late 17th century. The U.S. Army, in their various confrontations, found them to be fierce warriors and skilful strategists.---------------------------------- The present-day Apache groups include the Jicarilla and Mescalero of New Mexico, the Chiricahua of the Arizona-New Mexico border area, the Western Apache of Arizona, the Lipan Apache of southwestern Texas, and the Plains Apache of Oklahoma. There undoubtedly existed other Apache groups which are not as well-known by modern anthropologists and historians.
