Final answer:
The Civil War was primarily caused by the issue of slavery, along with economic differences and differences in beliefs about states' rights.
Step-by-step explanation:
The Civil War in the United States was primarily caused by the issue of slavery. Slavery was a deeply divisive issue between the Northern and Southern states. The North wanted to abolish slavery, while the South wanted to maintain it to support their agrarian economy.
Another contributing factor to the Civil War was economic differences between the North and South. While the North was industrialized and relied on wage labor, the South was agrarian and heavily dependent on slave labor.
Finally, the issue of states' rights also played a role in the cause of the Civil War. The Southern states believed in the concept of states' rights, while the Northern states believed in a strong central government.
