The Fort Sill Apache Tribe is comprised of the descendants of the Chiricahua and Warm Springs Apaches who lived in southwestern New Mexico, southeastern Arizona and northern Mexico until they were removed from their homelands and held as Prisoners of War by the United States from 1886–1914. Fort Sill Apache Tribal members are descended from 81 former Prisoners of War who received allotments in Oklahoma after their release.

The tribe’s territory includes trust lands in southwestern Oklahoma and southeastern Arizona.  Its Federally recognized reservation is located at Akela, New Mexico in the heart of its historic aboriginal territory.  The tribal headquarters is located two miles north of Apache, Oklahoma.

The tribe consists of about 670 tribal members, about half over the age of 18. Roughly 300 live in Oklahoma, the rest are spread across the United States, England, and Puerto Rico.
