Although states' rights wasn't the main reason for the Civil War, the idea played a significant role because the Confederacy felt like they weren't being given the opportunity to decide what was best for their states, even though the Constitution gave all states that right. Furthermore, the South felt especially threatened at the idea of stopping the spread of slavery or abolishing it all together because their economy was dependent on slave labor. Slavery was the main reason for the Civil War, and the main reason why Southern states wanted to secede from the Union and join the Confederacy.
