What was one of the major causes of the civil war?

Answer 1

Easiest answer is slavery. There were many issues dividing north and south, but it was the issue of slavery that was the most irreconcilable. Also, it is very doubtful that the population of the north would have endured a costly and bloody war with the south if not for the moral outrage caused by the practice of slavery in the southern states. In other words, if the southern states had seceded over tariffs or overreaching federal land grabs, I doubt the northern states could have persuaded their own citizens to fight and dies to preserve the union. Only opposition to slavery on moral and religious grounds gave the Union the political will to fight the war.

Answer 2

Slavery, the North wanted to abolish it while the South fought to keep it.

Answer 3

slavery, econamy, sectionlaism, and federal vs. states rights
