Slavery
Slavery was a major thing that led to the Civil War. The reason why slavery is a major part in leading into the Civil War because the north wanted to abolish slavery in the South. Because the North wanted to abolish slavery, there were abolitionists that tried to stop slavery which lead to more conflicts between the two regions. The South however wanted to keep slavery so they fought against the North in wanting to continue to keep slavery in the South. So because of this, a huge conflict between two regions in the United States which are the North and the South.
