Many of the early families' descendants still live around town. In the early twentieth century, Oden was a thriving town with staples such as a bank, grocery stores, and hotel. A predominantly agricultural community, Oden was incorporated in 1929. However, a 1931 fire that destroyed seven buildings and the Depression hit the town hard. In the past, cotton was an important cash crop.
