How did the number of factories in the north affect the start of the civil war?

In 1860, the North was in its way to become a major commercial and manufacturing economy. On the other hand, the South was still predominantly agricultural and highly dependent on slave labor. These major differences proved significant during the Civil War.

The North, with its large number of factories, had a greater ability to provide its army and its population with the necessary goods to win the war. 90% of the nation's manufacturing output came from Northern states. The North also produced 3,200 firearms for every 100 produced in the South. This type of economy attracted more immigrants, making the population of the North larger and providing it with more soldiers.
