Johnson County location map. Where is Johnson County?
History
Johnson County was created in 1836 from parts of Carter County. This followed several years of bickering over the location of Carter County’s seat, with residents of what is now Johnson County arguing that travel to Elizabethton was too lengthy and difficult. When their petition to move the seat to a more central location was rejected, they petitioned the state legislature for the creation of a new county. The new county was named after Thomas Johnson, an early settler. The county seat was initially named “Taylorsville” in honor of Colonel James P. Taylor (it was changed to “Mountain City” in the 1880s).
Most Johnson Countians supported the Union during the Civil War. The county’s residents rejected secession by a margin of 788 to 111 in Tennessee’s secession referendum on June 8, 1861. The county sent a sizable delegation to the Greeneville session of the pro-Union East Tennessee Convention in June 1861.
Due in large part to the county’s remoteness, the railroads did not reach Johnson until the early 20th century. The arrival of the railroads during this period aided the development of the timber and manganese mining industries.
