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

Cleveland County History

Originally occupied by the Quapaw tribe, the Quapaw ceded the area to the US Government soon after the Louisiana Purchase in 1818. During the late 1820s and 1830s, the area was given to the Creek and Seminole tribes after their forced removal from the southeastern United States. An agreement between the two tribes resulted in this area being part of the Seminole Nation, located west of the Creek Nation.

In 1866, these tribes were forced to cede the area to the Federal Government for siding with the Confederacy during the American Civil War[citation needed]. The area became part of the Unassigned Lands and was opened for white settlement on April 22, 1889.

After the passage of the Organic Act in 1890, Cleveland County was organized as County 3 and Norman became the county seat. For a short time, Cleveland County was known as Little River County, until an election in 1890. The voters selected the name Cleveland in honor of President Grover Cleveland over the name Lincoln
