Oklahoma Counties

There are seventy-seven counties in Oklahoma. Oklahoma originally had seven counties when it was first organized as the Oklahoma Territory. These counties were designated numerically, first through seventh. New counties added after this were designated by letters of the alphabet. The first seven counties were later renamed. The Oklahoma Constitutional Convention named all of the counties that were formed when Oklahoma entered statehood in 1907. Only two counties have been formed since then

Pittsburg County History

The area forms the present Pittsburg county was part of the Choctaw Nation after the Choctaw tribe was forced to relocate to Indian Territory from its home in the Southeastern United States in the early 1830s. Some important trails, including the Texas Road and one route of the California Trail passed through it. In 1840, James Perry established a village called Perryville that became an important stop near the place where the two trails crossed. During the Civil War, Perryville served as an important supply depot for Confederate forces until the Union Army captured and burned the town. It became defunct after the Missouri, Kansas and Texas Railway (MK&T) bypassed it in 1872, and the remaining inhabitants moved to McAlester. The Butterfield Overland Mail route followed a route through this area.

James J. McAlester moved to the Choctaw Nation in 1872, opened a trading post and married a Chickasaw woman. This qualified him to obtain citizenship rights in the Choctaw and Chickasaw Nations. When the MK&T built its line, McAlester laid claim to the coal deposits in the Perryville area, which he and some partners leased to the Osage Coal and Mining Company, which was owned by the Missouri Pacific Railroad and acquired by the MK&T in 1888.

Pittsburg County was formed on July 16, 1907 as an original county from Choctaw land. County leaders, thinking its coal production compared favorably with Pittsburgh, Pennsylvania, was named the new county after the Pennsylvania city with the "h" removed.

Oklahoma History Center
Located in east-central Oklahoma, Pittsburg County, created at 1907 statehood, incorporates 1,377.85 square miles of land and water. Because of the county's early coal production, leaders suggested the name Pittsburg, referring to Pittsburgh, Pennsylvania, comparing the county's large coal quantity to the northern state. The county borders McIntosh County on the north, Haskell and Latimer on the east, Atoka and Pushmataha to the south, and Hughes and Coal counties on the west. At the turn of the twenty-first century Pittsburg County's incorporated towns included Alderson, Ashland, Canadian, Crowder, Haileyville, Hartshorne, Indianola, Kiowa, Krebs, McAlester (county seat), Pittsburg, Quinton, and Savanna.

Pittsburg County is generally hilly and in places mountainous. The Ouachita Mountains extend into the southeastern portion, with sandstone hills contributing to most of the landscape in the northern and western sections. The Canadian River and Lake Eufaula form the northern boundary and drains most of Pittsburg County. A few creeks and streams, including Jack Fork Creek, drain into Boggy Creek and the Kiamichi River and eventually into the Red River....PITTSBURG COUNTY
