In the past, Camden and Benton County were known for sorghum production, however, the last sorghum production facility shut down in summer 2001. Tourism, however, is quickly supplanting it, with the well-promoted Tennessee Freshwater Pearl Museum at Birdsong Resort & Marina providing an influx of out-of-town dollars. Pearls, both farmed and harvested in the wild, have been a staple of Benton County for years. The Tennessee River Freshwater Pearl Farm is the only one of its kind in North America. Birdsong Resort, Marina and Lakeside RV and Tent Campgrounds offers tours of the farm and museum daily located off Interstate 40 at the Birdsong Exit # 133 which is halfway between Nashville and Memphis. Another notable event in Camden is the Bargain Highway, where parts of U.S. Highway 641 and U.S. Highway 70 are transformed into a 30-mile yardsale during Labor Day Weekend.
The first Euro-American settlers arrived in the Benton County area around 1818, shortly after (and probably before) the county was purchased from the Chickasaw. Camden has its roots as a stopover along the stage coach route between Nashville and Memphis. Initially known as "Tranquility," the community had attained the name "Camden" by the 1830s, a name influenced by the Revolutionary War-era Battle of Camden. When Benton County was created in 1835, Camden was chosen as the county seat. The city of Camden was officially incorporated in 1838.
