 In 1822, the Georgia state legislature established "Swainsborough" as the seat of Emanuel County. The town was named in recognition of Stephen Swain, the state senator who introduced the bill for the county's creation in 1812. The town's name was changed to "Paris" at its incorporation on February 18, 1854, but three years later reverted to its current name, Swainsboro.
 Early in its corporate life, much like other rural Georgia towns, Swainsboro depended on railroads for transportation. However, in the 1930s, many of the town's streets and sidewalks were paved, and Swainsboro found itself at the intersection of two major national highways, U.S. 1 and U.S. 80, thus earning its city motto: "Crossroads of the Great South". U.S. 1 was the principal highway from Maine to Key West, and U.S. 80, at that time, ran from Tybee Island, Georgia, to San Diego.
 The Emanuel County School District, run by the Emanuel County Board of Education, holds pre-school to grade twelve, and consists of three elementary schools, a middle school, a high school, and two academies. The district has 293 full-time teachers and over 4,664 students.
