Which war was primarily fought over the issues of slavery and states' rights?

The Civil War was primarily fought over the issues of slavery and states' rights, which became significant points of contention between the Northern states and the Southern states. The Southern states sought to maintain their right to govern themselves, including the autonomy to decide whether to allow slavery within their borders. They believed that the federal government was overreaching by trying to impose restrictions on slavery, which they viewed as an essential part of their economy and social structure.

In contrast, the Northern states, which were generally more industrialized and less reliant on slavery, were pushing for the abolition of slavery and advocating for the preservation of the Union. The conflict between these divergent views escalated, leading to the secession of several Southern states from the Union and eventually triggering the Civil War in 1861. The war addressed these fundamental issues, making it a pivotal conflict in U.S. history regarding the future of slavery and the balance of power between state and federal governments.
