The population was 244 in 2020. Richland Springs developed in the nineteenth century as a supply and processing center for local cotton growers and cattlemen. Jackson J. Brown and his family settled near the springs on Richland Springs Creek in December 1854 and were soon followed by the Tankersley and Duncan families. A private fort, Fort Duncan, was established near the springs in the late 1850s when trouble arose with Indians on the frontier, but it apparently fell into disuse shortly thereafter. The Brown School was constructed in 1868 and named for the neighborhood's original settler. The area attracted settlers through the 1870s, and in 1877 a Richland Springs post office opened in the store of Samuel E. Hays.
