[4] Portions of Johnson (1858), Jenkins (1905), Toombs (1905), Candler (1914), and Treutlen (1918) counties were taken from Emanuel's original borders.

It wasn't until 1854, the same time that the city of Swainsboro was formally incorporated, that the county was allowed to build a replacement.

In the late 1990s, the Emanuel County commissioners purchased the former U.S. Post Office building, which was built in 1936, to serve as an interim courthouse.

[7] The northern portion of Emanuel County, centered on Summertown and defined by a southern border heading from Garfield east-northeast and running north of Modoc, is located in the Upper Ogeechee River sub-basin of the Ogeechee River basin.

Since 1964, the only times the county has failed to back a Republican candidate in a presidential election were when southern Democrats Jimmy Carter and Bill Clinton were on the ballot.
