Answer:
Manufacturing
Explanation:
Before the Civil War, the South had an economy based on agriculture and slave labor. They focused on crops such as silk, cotton, food crops and cash crops and made a lot of money from them. They were also heavily involved in slave labour due to their heavy reliance on labor for their farmlands.
However the North was heavily reliant on manufacturing. This helped the North in the war as they manufactured weapons and other equipments for their use.
