The City of Middletown was originally incorporated in 1797 by the Jefferson County Court on 500 acres of land lying on a branch of the forks of Beargrass Creek that originally belonged to Jacob Meyers and Culberth Harrison. Though there is no recorded explanation why the city was named Middletown, it is commonly believed that that name was chosen because the town was in the "middle" of the two older cities of Louisville which was founded June 24, 1778, and Shelbyville, which was founded December 20, 1792. In 1871 the Kentucky General Assembly amended the original charter to increase Middletown's boundaries. After failing to hold elections and collect taxes after 1919, Circuit Judge McCauley Smith dissolved the city's charter on July 26, 1960, and Middletown lost its 163-year-old city status. The city's charter was restored as a sixth-class city on August 7, 1976 with a commission form of government. On July 15, 1982, this was upgraded to the status of a fourth-class city.
