Pulaski was designated the county seat and a courthouse erected on a square in the center of the county in 1811.
The location of Giles County on the Nashville and Decatur Railroad made it a center of activity during the Civil War. Though no major battle was fought within its boundaries, the county fell into Federal hands after the battle of Fort Donelson and was occupied by Union troops for several years.
