History
The present Pontotoc County was part of the land that the U.S. government granted in 1830 to the Choctaw tribe via the Treaty of Dancing Rabbit Creek. In 1837, the Chickasaw tribe was granted land within the Choctaw domain. In 1857, the Chickasaw Nation formed its own government on this land. However, few Chickasaw settled there until after the Civil War, mainly because of attacks by various Plains Indian tribes.

The first settlers were located in the vicinity of Boggy Depot during the 1840s. Camp Arbuckle was established to protect migrants traveling on the California Road. After the Civil War, settlements began spreading through the area. Some of the new settlers were illegal white intruders and outlaws. The first post office was established at Stonewall in 1878. The town of Ada was founded in 1890. After three railroads built lines through Ada, it became the dominant community of the area. Ada was named county seat when Pontotoc County was created.
