On January 7, 1867, theKingstree jail fire killed 22 imprisoned freedmen.[4] Also in 1867, the United States military oversaw the registering of voters in the county in preparation for the election of a new "reconstruction" government. In the Williamsburg District, there were 800 whites and 1,725 African-Americans who were eligible to vote under the new system.[5] A convention was held to organize a new constitutions for the state of South Carolina, the Williamsburg District was represented by William Darrington who was a white reverend from the Williamsburg District who had opposed slavery before the war as well as C.M. Olsen andStephen A. Swails, who were both African-American.[6] Darrington led a prayer at the opening of the convention on February 14, 1868.[7]
In 1868, the state constitution abolished the parishes and designated judicial districts formally as counties thus transforming the "Williamsburg District" into "Williamsburg County."[8]
In 1868, an election was held in which all men older than 21 years of age who had never been convicted of committing a felony nor were "prohibited on account of service under Confederate Government" were allowed to vote. This was a form of direct democratic election which had been set up by the reconstruction government of South Carolina. Almost all voters in this election were African American. No one who fought for the Confederacy was allowed to vote in the election. Many African-American officials were elected.Stephen A. Swails was an educated black man from Pennsylvania who had fought in the U.S. military in the54th Massachusetts Infantry Regiment during the civil war, and who was elected to represent Williamsburg County in the South Carolina State Senate.[9][10] F.H. Frost, J. Pendergrass and Fortune Guilds were three black men chosen to represent Williamsburg County in the South Carolina State House of Representatives. F. H. Frost was a black man elected as school commissioner. F.H. Swails was a black man elected as an auditor of Williamsburg County. C. Rasted and F.H. Frost were two black men who were elected as the assessors for Williamsburg County's county government. W.W. Ward was a white abolitionist from Massachusetts who was elected to be the sheriff of Williamsburg County, F.C. Cooper was a white abolitionist Quaker from Pennsylvania who was elected to be the clerk of the court of Williamsburg County and C.H. Pettingil, a Union Army officer from Boston, Massachusetts and former member of theMassachusetts Abolition Society who was elected as Williamsburg County's state constable representing the county in South Carolina's state government. In all of these elections local whites from South Carolina who had, by coincidence, not fought in the confederate military did run, however every single one of them lost. Every single man elected from Williamsburg County in this election was a member of the Republican Party.[11]
During this time, State Senator Stephen A. Swails also served as the mayor of Kingstree from 1868 until 1878. While mayor, Swails published and edited a newspaper called theWilliamsburg Republican, he also started a law firm. Swails became the most prominent member of the South Carolina senate, the president pro tempore, placing him in control of all bills that passed through the state legislature. Committed to universal education, he played a critical part in transforming The South Carolina College from a school for planter elite into the integratedUniversity of South Carolina.[12]

Prior to 1948, Williamsburg County was a Democratic Party stronghold similar to the rest of theSolid 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 & Williamsburg County, largely in part due to the Democratic Party's increasing support for African-American civil rights & enfranchisement. Dixiecrats managed to carry the county twice, while Republicans managed to carry the county three times in this timespan, while increased black registration led to DemocratHubert Humphrey winning the county in 1968. Since 1968, the majority African-American county has only backed a Republican once in1972, whenRichard Nixon won the county as he swept every county statewide in the midst of a 49-state national landslide.
