Final answer:
The main cause of the Civil War was slavery, which divided the country due to the opposing economic systems and debates over its expansion into new territories.
Step-by-step explanation:
The main cause of the Civil War was slavery. It was the fundamental issue that divided the country and sparked the conflict between the Northern and Southern states. The Southern states relied heavily on slave labor for their agricultural economy, while the Northern states had a more industrialized and free labor system.
The differing economic systems can be seen as a contributing factor to the conflict, as the North and South had opposing interests and priorities. However, it is important to note that slavery was at the core of these economic differences.
The debate over slavery escalated with the expansion of the United States into new territories. The issue of whether slavery would be allowed in these territories further deepened the divide between the North and South, ultimately leading to the outbreak of the Civil War.
