Unique History

Established at statehood in 1907, McClain County, was originally part of Curtis County in the proposed state of Sequoyah. The county was named for Charles M. McClain, a member of the Oklahoma Constitutional Convention and an early resident of Purcell.

In the 1870s large ranching operations north of the Washita River belonged either to those of Indian blood or those related to Indians by marriage. Black slaves formerly owned by Choctaw and Chickasaw families were also eligible to own land. Cotton gins in many small towns prepared raw cotton for the cotton press in Purcell, the county seat. Broom corn growing was also productive in the 1920s and 1930s.
