Q: Was the Civil War fought over the issue of slavery? The South, which was known as the Confederate States of America, seceded from the North, which was also known as the Union, for many different reasons. The reason they wanted to succeed was because there was four decades of great sectional conflict between the two. Between the North and South there were deep economic, social, and political differences. The South wanted to become an independent nation. There were many reasons why the South wanted to succeed but the main reason had to do with the North's view on slavery. All of this was basically a different interpretation of the United States Constitution on both sides. In the end all of these disagreements on both sides led to the Civil War, in which the North won. There were a few reasons other then the slavery issue, that the South disagreed on and that persuaded them to succeed from the Union. Basically the North favored a loose interpretation of the United States Constitution. They wanted to grant the federal government increased powers. The South wanted to reserve all undefined powers to the individual states. The North also wanted internal improvements sponsored by the federal government. This was more roads, railroads, and canals. The South, on the other hand, did not want these projects to be done at all. Also the North wanted to develop a tariff. With a high tariff, it protected the northern manufacturer. It was bad for the South because a high tariff would not let the south trade its cotton for foreign goods. The North also wanted a good banking and currency system and federal subsidies for shipping and internal improvements. The South felt these were discriminatory and that they favored Northern commercial interests. Now the main reason for the South's secession was the Slavery issue. This was the issue that overshadowed all others. At this time the labor force in the South had about 4 million slaves.
