city, seat (1892) of Seward county, southwestern Kansas, U.S. It lies near the Oklahoma border just north of the Oklahoma Panhandle. Founded in 1888, it was so-named because a local landowner, L.E. Keefes, was “liberal” in allowing the use of his well in time of drought. The community developed around a railroad terminus serving cattle ranchers. During World War II, Liberal Army Air Field, now the city's municipal airport, served as a training centre for bomber pilots; some 100 vintage aircraft are on display at the city's Mid-American Air Museum. The city now serves as a trading centre for a grain and livestock area. Located at the eastern edge of the Hugoton natural-gas field, Liberal relies on natural-gas and oil extraction, petroleum refining, and meatpacking. Gas-pumping plants are in the area. Liberal is the seat of Seward County Community College (1969). The Dalton Gang Hideout and Museum is located in Meade, some 40 miles (65 km) northeast (see Dalton Brothers). Inc. 1888. Pop. (1990) 16,573; (2000) 19,666.
