The United States purchased the large tract of land known as the Louisiana Purchase from France in 1803.Washington Irving,Charles J. Latrobe, and CountAlbert de Pourtalès accompanied Henry L. Ellsworth and others on an expedition inIndian Territory that may have passed through the far northwestern corner of the future Lincoln County.[1]
TheOsage hunted on land that includes present-day Lincoln County until they ceded the area in an 1825 treaty to the federal government. The government then assigned the land to theCreek and theSeminoles after they were removed from the southeastern United States. FollowingQuapaw removal in 1834, several small groups of Quapaw dispersed throughout Indian Territory. There were absentee groups of Quapaw living along the Red River and in Creek, Choctaw and Cherokee territory. There is a "Quapaw Creek" in the southern half of Lincoln County which was a village site for one of these absentee groups of Quapaw.[6] After theCivil War in 1866, theCreek andSeminoles were forced to give up lands that included present-day Lincoln County in Reconstruction Treaties for siding with the Confederacy.[1]
The federal government then used the area to resettle theSac and Fox,Potawatomi,Kickapoo andIoway tribes. Established in 1870, the Sac and Fox agency, established on the eastern edge of the present-day county, was the first settlement in the area.[1]
In 1890, the Jerome Commission negotiated with the tribes of the area such that they agreed to allotment of their reservation lands, except for the Kickapoo. Indian lands were allotted to individual tribal members and the excess were opened to white settlement in theLand Run of 1891. A separate land run was held later that year for the townsite of the predesignated county seat, Chandler. Lincoln County was organized and designated as County A. In 1895, the Kickapoo agreed to allotment and the land was claimed by settlers during theLand Run of 1895.[1]
The voters chose the name Lincoln County for County A in honor of PresidentAbraham Lincoln, selecting it over the names Sac, Fox, and Springer.[1]

The county economy has largely depended on agriculture. Cotton almost immediately became the dominant crop after white settlement. During the first decade of the twentieth century, Lincoln County was one of the top two counties producing cotton in Oklahoma. By the end of the Great Depression the economy had become more diversified. Oil furnished one-third of county tax revenue, and cattle raising and pecan growing became important income sources. By the turn of the 21st Century, the county economy had diversified and was based primarily on professional services, small businesses, and service industries.[1]
