Between 1890 and 1899 the Congress of the United States authorized the establishment of the first four national military parks: Chickamauga and Chattanooga, Shiloh, Gettysburg, and Vicksburg. The first and largest of these, and the one upon which the establishment and development of most other national military and historical parks was based, was Chickamauga and Chattanooga. It owes its existence largely to the efforts of General H.V. Boynton and Ferdinand Van Derveer, both veterans of the Army of the Cumberland, who saw the need for a national park to preserve and commemorate these battlefields during a visit to the area in 1888. The Park is located at Fort Oglethorpe, Georgia.

The defining events of Fort Pulaski occurred during the American Civil War. In April of 1862, Union troops directed rifled cannon fire at the fort breaching the southeast angle. Immediately after capturing the fort, Union Major General David Hunter, an ardent abolitionist, ordered the release of area slaves. Many were recruited into the Union army comprising the First South Carolina Colored Regiment. The park includes scenic marsh and uplands that support a variety of animal life characteristic of southern barrier islands. White-tailed deer, alligators, and raccoons as well as resident and migratory birds grace the landscape. Spanish moss drapes from yaupon holly bushes and vegetation includes cabbage palms, various wetland grasses, and a variety of temperate hardwood and pine trees. Fort Pulaski is located about fifteen miles east of Savannah.

Andersonville, or Camp Sumter as it was officially known, was one of the largest of many Confederate military prisons established during the Civil War.

The 515-acre park consists of the historic prison site and the National Cemetery.
