The North vs South debates over slavery were a series of political, social, and economic discussions and conflicts during the 19th century that focused on the institution of slavery in the United States. These debates became a critical factor leading to the Civil War, highlighting the stark differences between the industrialized North, which opposed the expansion of slavery, and the agrarian South, which relied on slave labor for its economy. The arguments surrounding slavery not only shaped regional identities but also influenced national policies and moral attitudes.
