During the period from 1800 to 1865, the issues of states' rights, tariffs, and slavery significantly contributed to the growth of sectionalism in the United States. Southern states, prioritizing states' rights, resisted federal authority, particularly regarding tariffs that they believed disproportionately favored the North. The moral and economic debates surrounding slavery further deepened the divide, leading to heightened tensions between the North and South. Ultimately, these conflicts culminated in the Civil War, as differing regional interests became increasingly irreconcilable.
