To address the conflict over slavery
There are many primary sources of conflict that led to the Civil War, one main issue was the issue of slavery. The Union was against the institution of slavery, whereas it was one of the South's major sources of income. If this institution was to be completely abolished as the Union wished, the economy in the South would be devastated. Another source of conflict came from the industries of the North, which competed against those of the South. As tensions grew, the flow of Southern raw materials was threatened, and Southern industrialization posed an economic threat.
