Barnwell County is a county in the U.S. state of South Carolina. As of the 2020 census, its population was 20,589. ^[1] It is located in the Central Savannah River Area. Its county seat is Barnwell. ^[2]

History

The Barnwell District was created in 1797 (effective in 1800) from the southwestern portion of the Orangeburg District, along the Savannah River. ^[3] It was named after John Barnwell, a local figure in the Revolutionary War. ^[4]

In 1868, under the South Carolina Constitution revised during Reconstruction, South Carolina districts became counties. The government was made more democratic, with county officials to be elected by male citizens at least 21 years old, ^[5] rather than by the state legislature as done previously.

In 1871, the legislature took the northwestern portion of the county to form part of the new Aiken County, the only county organized during the Reconstruction era. In 1874, the border with Aiken County was slightly adjusted. Aiken and Barnwell, with nearly equal, populations of Black and white people, had extensive violence in the months before the 1874 and 1876 elections, as groups of paramilitary Red Shirts rode to disrupt Black Republican meetings and intimidate voters to suppress Black voting. More than 100 Black men were killed in Aiken County during the violence, especially at Ellenton, South Carolina.

In 1895, white Democrats in the state legislature passed a new constitution, disfranchising most Blacks for more than 60 years by raising barriers to voter registration.

In 1897, the eastern third of the county was taken to form the new Bamberg County. In 1919, most of the southern half of the county was taken to form most of the new Allendale County, thus reducing Barnwell County to its present size.

Government and politics

Prior to 1948, Barnwell County was a Democratic Party stronghold similar to the rest of the Solid South, with Democratic presidential candidates receiving near-unanimous margins of victory in most years. The twenty years from 1948 to 1968 were a highly transitional time for the politics of South Carolina & Barnwell County, largely in part due to the Democratic Party's increasing support for African-American civil rights & enfranchisement. Segregationist candidates Strom Thurmond & George Wallace won the county in those aforementioned years, bookended by Democratic wins in 1952 & 1956 & Republican wins in 1960 & 1964. From 1972 on, the county has primarily Republican, but has become more of a swing county in recent years, backing the national winner in every presidential election from 2000 on except for 2020.
