In the 1890s, the government established five Civil War battlefield parks under the jurisdiction of the War Department, beginning with the creation of the
Chickamauga and Chattanooga National Military Park at
Fort Oglethorpe, Georgia, and the
Antietam National Battlefield in Sharpsburg, Maryland, in 1890. The
Shiloh National Military Park was established in 1894 in
Shiloh, Tennessee, followed by the
Gettysburg National Military Park in 1895, and
Vicksburg National Military Park in 1899. In 1933, these five parks and other national monuments were transferred to the National Park Service. Chief among modern efforts to preserve Civil War sites has been the
American Battlefield Trust, with more than 130 battlefields in 24 states. The five major battlefield parks operated by the National Park Service had a combined 3million visitors in 2018, down 70% from 10million in 1970.
