The Cheyenne, a Plains Indigenous nation, preserve a vibrant culture rooted in the Algonquian language family, with about 1,500 speakers today. Traditions thrive through ceremonies like the sacred Sun Dance (annual, four-day), Warrior Dance, Women's Dance, and the Cheyenne National Holiday Pow Wow. Regalia features intricate beadwork, quillwork, and natural pigments. Spirituality centers on Maheo, the Great Spirit, with many blending traditional beliefs and Christianity since the 1800s. Historical trauma from forced boarding schools (e.g., Carlisle, Riverside) suppressed language and culture, yet survivors passed traditions intergenerationally. Today, the Northern Cheyenne (Montana) and Southern Cheyenne (Oklahoma) maintain separate tribal governments — the former with three branches and a nine-member Council, the latter with a 13-member General Council. Economies rely on ranching, oil, and tourism (Little Bighorn Battlefield draws 400k+ annually); the Northern Cheyenne operate a casino and historic Irma Hotel. The Cheyenne Arapaho Tribal College in Oklahoma serves Native students. Culture endures through adaptation and sovereignty.
