The US Civil War is called a modern war (the first, in fact) because the soldiers used modern machine guns for one of the first times. Other new inventions used during the war, although none were widespread, included Submarines, Zepplins, and Ironclad ships. The Civil War was also the first war to feature total mobilization of both sides, as each directed all of its production towards the war effort.
