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

Jackson County History

After a dispute over the Adams-OnĂ­s Treaty of 1819, both the governments of the United States and the state of Texas claimed ownership of some 1,500,000 acres (6,100 km2) in what was then operated as Greer County, Texas. Litigation followed, and in the case of United States v. State of Texas 162 US 1 (1896), issued on March 16, the Supreme Court, having original jurisdiction over the case, decided in favor of the United States. Greer County was then assigned to the Oklahoma Territory on May 4, 1896, and when Oklahoma became a state, in addition to becoming Jackson County, the region was also further split into Greer, Harmon, and part of Beckham counties.

Altus was originally designated as the seat of Jackson County. Olustee vied in an unsuccessful bid to replace Altus as the seat in an election on July 18, 1908.
