Upper Arkansas Indian Agency

History
The Upper Arkansas Agency was established in 1855 to serve the Indians living along the Arkansas River in what is now eastern Colorado and western Kansas. The principal tribes for which this agency was responsible were the Southern Cheyenne and Arapaho, although the Kiowa, Comanche, Apache (Kiowa-Apache) and Caddo were also under their jurisdiction for a time. These tribes had previously been assigned to the Upper Platte Agency.

The agency was under the Colorado Superinendency 1861-1880

In 1864, a separate Kiowa Agency was created, which took jurisdiction over all but the Cheyenne and Arapaho tribes.

The agency moved often and was at the following locations for the years listed:


 * 1855-1861 -- at Bent's Fort in Colorado
 * 1861-1862 -- at Fort Wise in Kansas
 * 1862-1866 -- at Fort Lyon in Kansas (with a short stay at Fort Zarah in Kansas)
 * 1866-1869 -- at Fort Larned in Kansas
 * 1869-1874 -- at Darlington, Oklahoma, due to the move of the Cheyenne and Arapaho to Oklahoma.

In 1874, the name was officially changed to the Cheyenne and Arapahoe Agency.
