Step-by-step explanation:
The main cause(s) of the Civil War were A) Economic disparities and slavery, B) States' rights and cultural differences, and C) Expansion of slavery into new territories. These factors contributed to the tensions that eventually led to the war.
Slavery played a central role in the conflict. The Southern economy heavily relied on slave labor for crops like rice, cotton, and tobacco, while the North did not benefit economically from slavery, leading to economic disparities.
In addition, differences in states' rights and cultural norms contributed to the tensions between the North and South. The Southern states believed in local control, while the North believed in centralized control over certain issues, such as slavery.
