After a dispute over the 1819Adams-Onís Treaty and the related 1828Treaty of Limits, the governments of both the United States and the state of Texas claimed ownership of some 1.5 million acres (6,100 km2) in what was then operated asGreer County, Texas. The county was named for former Texas lieutenant governor,John A. Greer.[4] Litigation followed, and in the case ofUnited States v. State of Texas162U.S.1 (1896), with a ruling issued on March 16, theSupreme Court, having original jurisdiction over the case, decided in favor of the United States.
The county was assigned to the Oklahoma Territory on May 4, 1896. When Oklahoma was admitted as a state, Greer County was established according to its current boundaries; the remaining former county area was organized asHarmon,Jackson, and part ofBeckham counties. The town of Mangum, designated as the county seat in 1886 when it was part of Texas, continued as the seat of Greer County, Oklahoma.[4] From its establishment until at least 1903, Greer County was asundown county, prohibiting African Americans from living in the county.[5]
Originally developed for agriculture, the rural county had its peak of population in 1930. Mechanization of agriculture reduced the need for farm labor, and the population has declined as people migrated to cities for work.

^"Ban Placed on Negroes".Scott County Kicker. Benton, Missouri. September 5, 1903. p. 2 – via Chronicling America.Because the ban has been placed on the negroes by the citizens of Greer county, Okla., there will be an estimated loss of 5,000 bales of this year's cotton crop. Greer county, which, until a few years ago, was a part of Texas, is one of the big cotton producers of the territory. This year the farmers raised 20 per cent. increased acreage and a 15-per-cent. increase yield, but there is a labor famine. The growers have been threatened by the citizens in general upon every attempt to import negroes, but unless the necessary laborers are secured in the immediate future the financial loss will be great. The growers now have a movement on foot to bring 100 Mexican families to pick the cotton crop. Since the organization of Greer county no negroes have been allowed to live within its boundaries.
