Langston was founded on April 22, 1890 by Edward P. McCabe, an African-American political figure from Kansas. McCabe helped lead a migration of black settlers from southern U.S. states who hoped to escape discrimination by creating a majority-black state in what was then the Territory of Oklahoma. He named the town for John Mercer Langston, a black member of the 51st United States Congress from Virginia. McCabe used traveling salesmen and African-American newspapers to advertise lots for sale in Langston, and the deeds which accompanied the sale of these lots stipulated that their re-sale could only be to other African-Americans. By 1891, Langston had a population of 200, which included a preacher, doctor, and schoolteacher. By 1892, the town had 25 businesses, with a bank and a public school. A Roman Catholic mission was established in 1893 by Rev. Bishop Theophile Meerschaert and the Benedictine Sisters. The town had a telephone system in service in 1895. In 1897, the Oklahoma Territorial Legislature passed a law creating the Colored Agricultural and Normal University at Langston.
