The Choctaw Nation signed theTreaty of Doak's Stand in 1820, ceding part of their ancestral home in the Southeastern U.S. and receiving a large tract inIndian Territory. They signed theTreaty of Dancing Rabbit Creek in 1830, which ceded the remainder of their original homeland. Most of the remainder of the Choctaw wereremoved to Indian Territory, escorted by federal military troops, in several waves.[3]
In 1832, the federal government constructed the Choctaw Agency in Indian Territory about 15 miles (24 km) west ofFort Smith, Arkansas. The town ofSkullyville developed around the agency. It was designated as county seat ofSkullyville County, the capital of theMoshulatubbee District of which Skullyville County was a part, and the national capital of theChoctaw Nation.
In 1834, the U.S. Army builtFort Coffee a few miles north of Skullyville, but reassigned the garrison after four years. The Methodist Church took over the facility, converting it for use as the Fort Coffee Academy for Boys, a missionary school. That church also established the New Hope Seminary for Girls in 1845, just east of town. In 1847, the Choctaw Agency burned and its functions were transferred toFort Washita.[3]
During the Civil War, the Choctaw allied with the Confederacy and many of their men served in its army. TheBattle of Devil's Backbone was fought near the present town of Pocola on September 1, 1863. Union Major GeneralJames G. Blunt defeated Confederate Brigadier GeneralWilliam Cabell. Union troops burned the Fort Coffee Academy in 1863, because it was being used to house Confederate troops.[3]
In 1866, the Choctaw government reopened New Hope Seminary, but never rebuilt a boys academy. New Hope Seminary operated until it burned in 1896. The first school for Choctawfreedmen opened at Boggy Depot. In 1892, the Tushkalusa (Black warriors) Freedmen Boarding school opened three miles southeast of Talihina.[3]
From 1886, development of coal mining and timber production attracted considerable railroad construction; the Choctaw, Oklahoma and Gulf Railroad built tracks from Wister west to McAlester. In 1898, the company extended the line east from Wister to Howe, continuing the line to Arkansas in 1899. (This line was leased to the Chicago, Rock Island and Pacific Railway in 1904).
In 1896, the Kansas City, Pittsburg and Gulf Railroad (acquired by the Kansas City Southern Railway in 1900) built tracks through the region from north to south, exiting into Arkansas near the Page community in southern LeFlore County. In 1900-01, thePoteau Valley Railroad built a line fromShady Point toSutter (later known asCalhoun, which they abandoned in 1926. Also in 1900-01, the Arkansas Western Railroad constructed tracks from Heavener east to Arkansas. In 1901, the Fort Smith and Western Railroad connected Coal Creek west to McCurtain in Haskell County. In 1903-04, the Midland Valley Railroad laid tracks from Arkansas west through Bokoshe to Muskogee. The Oklahoma and Rich Mountain Railroad, owned by the Dierks Lumber and Coal Company, constructed the county's last railroad, from Page to the lumber town of Pine Valley in 1925–26.[3]
Robert S. Kerr, former governor of Oklahoma and U.S. senator, established a ranch outside Poteau in the 1950s. In 1978, the family donated this residence to the state. It was adapted and opened for use as the Kerr Conference Center and Museum. The Kerr Center for Sustainable Agriculture and the Overstreet-Kerr Historical Farm are also in the county.[3]
