Which most influenced the Northern and Southern positions about slavery?

The Northern and Southern positions on slavery were primarily influenced by economic interests and social ideology. The South’s agricultural economy relied heavily on slave labor for the cultivation of cash crops like cotton, leading to a strong defense of the institution. In contrast, the North, increasingly industrialized and urbanized, began to view slavery as morally objectionable and economically outdated, advocating for abolition and labor reform. These differing economic structures and cultural values ultimately deepened the divide between the two regions.
