The Darlington Agency was an Indian agency on the Cheyenne and Arapaho Indian Reservation prior to statehood in present-day Canadian County, Oklahoma. The agency was established in 1870. The agency established at Fort Supply the previous year was moved to a more accessible location for the tribes. Brinton Darlington, a Quaker for whom the agency was named, was the first United States Indian agent at the agency, a position he held until his death in 1872. Read more on Wikipedia
