The were many causes to the Civil War. Slavery wasn't just the only reason that the Civil War started. The Southern and Northern states fought about their rights, expansion, industry, farming, and Abraham Lincoln. In the 1800's the Northern states moved to industry. The Southern states had large farms and depended on the slaves to do their farming. The Southern states did not like Lincoln because he was against slavery and the Southern states needed slaves. When the United States expand west every new state would become a battleground between the Southern and the Northern. The Southern thought they would lose their rights. The Northern and Southern states fought over many things but in the end it just kept coming back to slavery.
The Civil War was about how the North no longer wanted slaves and the South did. The political power broke in Washington and planned on making no slaves aloud in the Union. The South didn't like that because they needed their slaves to work on their farms. The South said its the "way of life" and that they needed their slaves. If you came from the North you were rich and you don't need slaves. That is why the federal government agreed with the Northern state views. The Civil War's main issues were slavery but there were reasons why we should or should not have slaves.
The Civil War was the costliest and most deadliest war ever fought on American soil. There were 620,000 of 2.4 million soldiers killed and many more were injured. The election of Abraham Lincoln made seven Southern states to secede and make the Confederate States and four more states later joined. The Civil War was based on slavery. The North was manufacturing, the industry was good and was mostly limited to small farms. While the South was based on larger farming and depended upon slaves to grow crops like cotton and tobacco. The North did not like slaves, the north could do things on their own. And the South needed slaves to do their work for them. This is how the Northern states were richer and dependable rather than the Southern states. In the end the wars most focus was on slaves. There are other reasons why the war was fought but it all revolved around slavery.
