Created at the American Panorama Company in Milwaukee by 17 German artists, The Battle of Atlanta cyclorama took five months to create before it debuted in Minneapolis in 1886. Painted 22 years after the Battle of Atlanta, the painting originally depicted the battle from a Northern perspective as a heroic Union victory so that it would appeal to Northern audiences. When the painting relocated to Atlanta in 1892, it was slightly modified and advertised as “the only Confederate victory ever painted” to appeal to its new Southern audiences that maintained Confederate sympathies. The 1864 Battle of Atlanta was not a Confederate victory, and most of these changes from 1892 were reversed in the 1930s.
