After the Civil War, northern capitalists began investing heavily in East Tennessee, helping the region's ravaged economy recover. Knoxville and Chattanooga experienced manufacturing booms, and their populations grew exponentially. Other cities in the region, such as Lenoir City, Harriman, Rockwood, Dayton, and Englewood, were founded as company towns during this period. In 1899, the world's first Coca-Cola bottling plant was built in Chattanooga. In the early 1900s, railroad and sawmill innovations allowed logging firms such as the Little River Lumber Company and Babock Lumber to harvest the virgin forests of the Great Smokies and adjacent ranges. The Burra Burra Mine— established in the 1890s in the Copper Basin— was at its height one of the nation's largest copper mining operations. Coal mining operations were established in coal-rich areas of the Cumberland Plateau, namely in Scott County, northern Campbell County, and western Anderson County. In the early 1890s, Tennessee's controversial convict lease system sparked a miners' uprising in Anderson County that became known as the Coal Creek War. While the uprising was eventually crushed, it induced the state to do away with convict leasing, making Tennessee the first southern state to end the controversial practice.
