How were arguments over slavery dividing the nation?

Arguments over slavery were deeply polarizing, creating significant regional tensions between the North and South. The North, increasingly industrialized and favoring abolition, saw slavery as morally wrong, while the agrarian South relied on it for their economy and social structure. Key events, such as the Missouri Compromise and the Dred Scott decision, exacerbated these divisions, leading to a growing sense of sectionalism. Ultimately, these contentious debates laid the groundwork for the Civil War, as compromise became increasingly elusive.
