The North was richer than the South. It’s important to know that the North had an advantage in manufacturing and industrial production, while the South relied on farming and agriculture.
The North was more industrially advanced, it had more factories and railroads, which meant that it could produce more supplies for its armies than the South could. In addition, the North had better transportation networks than the South, which allowed it to move men and supplies more quickly.
The North had a larger population than the South, so it had more soldiers available to fight on its side. It also had more money because of its industrialization. This allowed it to hire more soldiers and buy more supplies for its army. This was very important because many people in the South were farmers who didn’t have much money or interest in fighting for either side in the war. They simply wanted to be left alone so they could farm their land in peace without interference from either side.
The North had a better navy than the South did because of its industrialization and larger population, as well as its access to raw materials that allowed them to build better ships than those made by Southern shipwrights who were limited by what resources they could find locally (wood was scarce in much of the South).
