Clyde was named after Sir Colin Campbell, Lord Clyde.
The history of the town is uncertain, in part due to destruction of records in a fire. The Bryan county seat was in a town called Eden since at least 1860; some think Eden was an earlier name for the same place later known as Clyde. In either case, by 1901 Clyde was listed as the Bryan County seat, keeping that role through 1935.
By 1901 it was in Clyde, Georgia, which may have been the same location formerly known as Eden.
Clyde served as the seat to 1935; in 1937 Pembroke took on that role.
Bulloch County, Georgia lies to the northwest, Effingham County, Georgia to the north, Chatham County, Georgia to the northeast, Liberty County, Georgia to the south, and a small portion of Evans County, Georgia to the west.
Sergeant Clyde A. Thomason (1914-1942) was a United States Marine who was posthumously awarded the Medal of Honor for heroism at the cost of his life while leading an assault on Makin Island on 17 August 1942.
Clyde A. Thomason was born in Atlanta, Georgia on 23 May 1914, and after his graduation from high school there, traveled widely throughout the United States in a "jalopy" with companions.
The Medal of Honor was conferred posthumously and was presented to his mother by Under Secretary of the Navy, James Forrestal, at ceremonies in January 1943 in Washington, D.C. Following his death, the people of Georgia bought a sufficient number of War Bonds to purchase for the Navy a cruiser, the USS Atlanta.
