Apache refers to a group of tribes who live in Arizona, New Mexico, Oklahoma and Texas, including the Chiricahua, Jicarilla, Lipan, Mescalero, Plains Apache, and Western Apache people. Throughout history, these groups have been identified by a number of names, and the term Apache has also been used to describe many Native groups, including the Navajo. Like the Navajo, the Apache are descended from Athabascan people who migrated from Canada and Alaska, settling in the Southwest sometime between 1300 and 1500 A.D.Historically, they are nomadic people known for their skill as hunters, living primarily off the buffalo. They did practice some agriculture beginning in the 18th century. Traditionally, several extended families lived close to one another and cooperated in gathering food and providing defense. Medicine men are an important part of Apache culture. In the 18th century they were pushed out of the Southern Plains region by the Comanche and moved further into the Southwest. Apache reservations were created by the federal government in the late 19th and early 20th centuries. For centuries, basket-making has been an important part of Apache life, as these were the ideal vessels for carrying their belongings over long distances. Apache artists are also known for their beautiful and intricate beadwork.
