The Civil War produced different results in the North than in the South. During the war, the need for weapons and other metal products had caused a boost in steel production. There were plenty of raw materials. Now, mining and refining of metals became the backbone of Northern industry. New technologies sprouted from this period of growth, like the first trans-Atlantic telegraph cable, the typewriter, and the camera. The ravages of battle caused a little rebuilding to do. Besides that, the Northern economy actually benefited from the conflict. There were new markets for products used by the Union Army. Northern factories were producing more than before. Booming factories meant that bankers and investors were making profits.
