Cheyenne military societies are one of the two central institutions of traditional Cheyenne Indian tribal governance, the other being the Council of Forty-four. While council chiefs are responsible for overall governance of individual bands and the tribe as a whole, the headmen of military societies are in charge of maintaining discipline within the tribe, overseeing tribal hunts and ceremonies, and providing military leadership. Historically, council chiefs selected which of the six military societies would assume these duties; after a period of time on-duty, the chiefs would select a different society to take up the duties.
