Scott County was formed in 1814 from Lee, Washington, and Russell Counties and was named for native Virginian Gen. Winfield Scott in recognition of his victories during the War of 1812; Scott later became commander of the United States Army. Natural Tunnel, about 850 feet long, is located there and was formed more than a million years ago. The Carter Family resided in the county, and the original trio of Alvin Pleasant “A.P.” Carter, Sara Dougherty Carter, and Maybelle Arrington Carter first recorded music in the 1920s. Gate City is the county seat. Before the first Europeans permanently settled in Tennessee in 1769, the area was inhabited by Native American tribes including the Cherokee, Creek, Chickasaw, and Shawnee. Until 1784, the territory composing Tennessee was part of North Carolina. Tennessee became the 16th state admitted to the United States in 1796. Notable residents of Tennessee included U. S. Presidents Andrew Jackson, James K. Polk, and Andrew Johnson, as well as frontiersman David Crockett. Nashville is the capital city of Tennessee and an important center for country music.
