In 1887 the northern part of the county was occupied by the Mallet Ranch. The foreman, Dave Ernest, sold the ranch to a merchant from San Antonio who used the land for driving cattle towards Kansas. On October 24, 1905, Gaines County became an organized county in Texas. Land was donated by non-resident landowners which would become the town of Seminole, Texas, the county seat. In 1912 a small post office opened up east of Seminole that was named after a local ranch brand that would later become Loop, Texas. In 1917 the Santa Fe Railroad came through Blythe, Texas, but its name was changed to Seagraves, Texas after the company discovered they had a town by the same name already located on the line.
