In the late 17th century, the first Euro-American explorers arrived in the area which is now Mountain City using existing Native American trails. The town was founded in 1836 and was originally called Taylorsville, in honor of Colonel James Taylor. In 1885, the name was changed to Mountain City, to reflect it being situated in one of the highest valleys in the state.
Mountain City and Johnson County have a long and enduring musical heritage with the first Mountain City Fiddlers Convention being held in 1925. This is considered a landmark event in the modern history of Appalachian traditional music with the musical gathering greatly contributing to the development of the genre of country music. The anniversary of this event is celebrated every year in August at the Old Time Fiddlers Convention held at the Old Mill Music Park in nearby Laurel Bloomery.
