Sumter County History

Sumter County and its county seat were named for Revolutionary War General Thomas Sumter (1734-1832), who was a resident of the area. This county has changed its name and boundaries several times. In 1785 Claremont County was formed as a part of Camden District; a part of the county was later split off in 1791 to form Salem County. Claremont, Clarendon, and Salem counties were combined into Sumter District in 1800. Clarendon was once again split off in 1857, however, and another small part of Sumter County went to form Lee County in 1902. This part of the state began attracting English settlers from the lowcountry and from Virginia in the mid-eighteenth century. The area known as the High Hills of Santee, a narrow ridge along the Wateree River, was famous for its healthy climate and rich soil. Sumter County eventually became a leading agricultural region. In 1941, Shaw Air Force Base was established near Sumter, and it continues today as an active duty fighter base. Confederate General Richard Heron Anderson (1821-1879) was a Sumter resident, as were opera singer Clara Louise Kellogg (1842-1916) and educator Mary McLeod Bethune (1875-1955).
