Sumter County, Georgia: History
=== Foundation and antebellum years ===
Sumter County was established by an act of the state legislature on December 26, 1831, four years after the Creek Indians were forced from the region when the state acquired the territory from them in the 1825 Treaty of Indian Springs. Sumter, the state's 80th county, was created after population increases by a division of Lee County, now situated to its south. The county was named for former General and United States Senator Thomas Sumter (1734–1832) of South Carolina. When the county was organized, Sumter was 97 years old and the last surviving general of the American Revolution (1775–1783).
Shortly thereafter, a committee chose a central site for the county seat, and laid out what became the town of Americus. Many of the county's earliest white residents acquired their land through an 1827 state land lottery. Like many other white settlers, they quickly developed their property for cotton cultivation. Since the invention of the cotton gin at the end of the 18th century, short-staple cotton was the crop of choice throughout the Black Belt of the South.
The rich, black soil, combined with ready market access via the Flint River (bordering the county on the east) or the Chattahoochee River (farther west), put Sumter among the state's most prosperous Black Belt counties by the 1840s and 1850s. Cotton agriculture was economically dependent on enslaved African Americans. By the 1850 census, the demographic makeup of the county had become 6,469 whites, 3,835 enslaved African Americans, and 18 free people of color. By the 1860 census, the county had 4,536 whites, 4,890 enslaved African Americans and two free people of color.
During the American Civil War (1861–65), the small village named Andersonville, 9 mi (14 km) north of Americus on the county's northern edge, was selected by Confederate authorities as the site for a prisoner-of-war camp. The Andersonville prison was built in neighboring Macon County, and became the largest such prison in the South. During the camp's 14 months of operations, some 45,000 Union prisoners suffered some of the worst conditions and highest casualties of any of the camps. Today, the Andersonville National Historic Site serves as a memorial to all American prisoners of war throughout the nation's history. The 495-acre (2.00 km2) park lies in both Macon and Sumter Counties and consists of the historic prison site and the National Cemetery, which originally was reserved for the Union dead. …
