Hitchcock County was a proposed political subdivision created by the Sequoyah Constitutional Convention.
Sequoyah was an attempt by the Five Civilized Tribes and others in the Indian Territory—who did not wish to be incorporated into an American state—to establish full statehood for the territory.
Although their attempt to achieve statehood was unsuccessful, many of their deliberations in establishing proposed counties proved useful to the framers of Oklahoma, who met just two years later for the purpose of establishing the State of Oklahoma.
The boundaries of modern-day Choctaw, Pushmataha and McCurtain counties in Oklahoma are derived largely from the work of the Sequoyah Constitutional Convention.
The county was named in honor of Ethan Allen Hitchcock (1835-1909), the federal Commissioner to the Five Civilized Tribes, formerly the American minister (ambassador) to the Russian Empire.
