The Red Cloud Agency was an Indian agency for the Oglala Lakota as well as the Northern Cheyenne and Arapaho, from 1871 to 1878. It was located at three different sites in Wyoming Territory and Nebraska before being moved to South Dakota. It was then renamed the Pine Ridge Reservation.
As stipulated in the Fort Laramie Treaty (1868), the US government built Indian agencies for the various Lakota and other Plains tribes. These were forerunners to the modern Indian reservations. The Red Cloud Agency was established for the Oglala Lakota in 1871 on the North Platte River in Wyoming Territory. The location was one mile west of the present town of Henry, Nebraska.
In August 1873, the agency was moved to the northwestern corner of Nebraska, near the present town of Crawford. Constructed on a hill overlooking the White River, the agency buildings included a large warehouse, offices, home for the agent, blacksmith shop and stables for horses. A school house was later added. Two trading stores were also built adjacent to the agency.
Following the killing of agency clerk Frank Appleton, the government assigned US troops to the agency in March 1874. The military encampment was named Camp Robinson (later known as Fort Robinson). The Red Cloud Agency was the center of much activity during the Great Sioux War of 1876-77. In May 1877, Crazy Horse and allied leaders came with their people to the Red Cloud Agency for surrender. Following the killing of Crazy Horse, the agency was moved further west.
The site of Red Cloud Agency No. 2 is included in Fort Robinson and Red Cloud Agency, a United States National Historic Landmark.
