I looked into the history behind; and the current situation of the Cheyenne Tribe, how they transpired from a highly developed (by neolithic technological standards) , tribe, both militarily and political powerful . and how their interaction with imperialist European powers, both benefited and negatively affected the tribe. Additionally, how as a tribe they had to deal with US Federal restrictions and regulation on land and religion.
The Cheyenne Tribe, were originally located in the hills and surrounding areas of Missouri. Their contact with the Spanish and their technologies e.g. Horses allowed the Cheyenne the opportunity to hunt buffalo more effectively, this is a early example of the benifits that trading nations (from Europe) brought to the Americas. The whole survival of the tribe revolved around the buffalo, food, clothing, shelter and religion, all were focused it.
The Cheyenne tribe, like many tribes on the west side of the Appalachian mountains, were met with full force of the expanding US government, who in a bid to secure land for its citizens in legistation like the 1862 'Homestead Act', promised and comprised treaties with the Cheyenne's (which they broke) . Cheyenne opposition to US expansion, came apparent in 1864 (while US government, was focued on the civil war), when like the 'Apache' and the 'Cherokee' sought retribution upon white settlers. Leading US retaliation, the Sand Creek Massacre (1864) and further Cheyenne attacks; The Cheyenne participated in the Battle of the LittleBighorn (1876).
As with many other tribes, the Cheyenne have been subject to US reservation programs and currently
The Southern Cheyenne and Arapaho currently live in Oklahoma, while the Northern Cheyenne live on the Tongue River Indian Reservation in southeastern Montana.
