Aledo was established in the 1850s when the railroad was extended to that point. It was briefly named “DeSoto”, after Hernando de Soto, until the discovery of an identically named village in Jackson County, Illinois. Development began in the 1850s, and the oldest surviving buildings date from the following decade. A post office has been in operation at Aledo since September 24, 1856. In 1857, the county seat was moved to Aledo from Millersburg after a countywide referendum. Aledo was incorporated on August 15, 1863. In the 1950s, the first Tastee-Freez in the United States was built in the downtown.> The Downtown Aledo Historic District was established in 2016, with 75 contributing historic buildings in the downtown area.
