Arthur was founded in 1913 to be the seat of Arthur County, then just organizing. The town and county were both named for President Chester A. Arthur. Arthur was incorporated as a village in 1944. The first county office was a covered wagon, with a one-room courthouse being built in 1915. A year before that, in the Spring, a general store was constructed, and afterward a newspaper, the first church and the post office were established. A one-room high school was also built in 1914, expanding to two rooms in 1920. In 1916 the Arthur State Bank was founded. Into the 1920s, Arthur continued to be built. The town got electricity in 1926, though most of the county would not have it until the early 1950s.
