When and why did the Confederacy lose the war?

Answer 1

'When'

Because the Confederate States of America had a much smaller population than the Union, and an economy that wasn't industrialized and depended almost entirely upon one cash crop. The Confederacy, though continually losing less men than the Union in battles, didn't have as many soldiers in the first place, so that, despite the cleverness of the Confederacy's military commanders, the South still lost more men than it could afford to in the face of the Union's vastly superior numbers. The Confederacy was also, as a result of the lack of industrialization, poorly equipped for a long war, running out of food, clothing, and other essentials for the army. The only economic ally, Britain, decided against getting involved, importing "King Cotton" from India instead, driving the Confederacy completely bankrupt. That's 'why' the CSA lost the Civil War.
