Clarksville is a city in and the county seat of Montgomery County, Tennessee.
The city was incorporated in 1785 as Tennessee's first incorporated city, and named for General George Rogers Clark, frontier fighter and Revolutionary War hero, and brother of William Clark of the Lewis and Clark Expedition.
Clarksville is the home of Austin Peay State University; The Leaf-Chronicle, the oldest newspaper in Tennessee; and neighbor to the Fort Campbell, United States Army base.
In 1861, both Clarksville and Montgomery County voted unanimously to join the Confederate States of America. The proximity of the birthplace of Confederate President Jefferson Davis; about 20 miles across the border in Fairview, Christian County, Kentucky, gave the city a strong tie to the CSA, and both sides saw the city as strategic and important.
Confederate General Albert Sidney Johnston set up a defense line around Clarksville expecting a land attack; however, the Union sent troops and gunboats down the Cumberland River, and in 1862, captured Fort Donelson, Fort Henry, and Clarksville. Between 1862 and 1865, the city would shift hands, but the Union would retain control of Clarksville.
