Clinton

Established in 1802 as the county seat of Anderson County and originally named Burrville in honor of Aaron Burr, the first-term vice president under Thomas Jefferson, Clinton was renamed by the Tennessee legislature in 1809. The arrival of the railroad after the Civil War made large-scale mining of coal the area's main industry for nearly a century, and the resulting growth in population was one of the deciding factors in the federal government's building of the "Secret City" of Oak Ridge, as part of its World War II Manhattan Project, just 16 miles to the southwest. From the late 1880s until the completion of the Tennessee Valley Authority's Norris Dam in 1936, Clinton was also a major center of the Clinch River freshwater pearl trade. Construction of the dam altered the river's temperature, which killed off the pearl industry, but the creation of Norris Lake became the basis on which the area's tourism industry was founded.
