Liberal is the county seat of Seward County, Kansas, United States. As of the 2010 census, the city population was 20,525.
S.S. Rogers built the first house in what would become Liberal in 1872. Rogers became famous in the region for giving water to weary travelers. Reportedly, Liberal gained its name from the common response to his acts of kindness, "That's very liberal of you." In 1885 Rogers built a general store, and with it came an official U.S. Post Office. Rogers named the post office 'Liberal'. After the railroad was built close by, a plan for the town site was created in 1888. A year later the population was around 800.
Drought caused some farmers to give up and look for more fertile territory; however, when the nearby Indian Territory was opened, more settlers headed to the cheap land that would become Oklahoma.
