Jackson's “Proclamation to the People of South Carolina” — Nullification Crisis U.S. Pres. Andrew Jackson issued his “Proclamation to the People of South Carolina” on December 10, 1832, in response to South Carolina's refusal to be bound by federal tariffs. In it Jackson asserted the supremacy of the federal government and rejected South Carolina's argument that it, as a state, had the right to reject laws made by the federal government that it deemed unconstitutional. Jackson's proclamation was an escalation of the Nullification Crisis, and some argue that it helped lay the foundation for the American Civil War.

The Nullification Crisis strengthened the principle of federal supremacy by decisively challenging the doctrine that individual states possessed the authority to declare federal laws unconstitutional and void within their borders.12

The crisis reached a turning point when President Andrew Jackson issued a proclamation on December 10, 1832, denouncing nullification as incompatible with the existence of the Union and contrary to the Constitution. To enforce national authority, Jackson requested and received from Congress the Force Bill, which authorized the president to use military force to ensure the collection of federal import duties.1234

By demonstrating a firm resolve to employ federal power to uphold national law, Jackson effectively isolated South Carolina, which failed to gain support from other states for its position. The resolution of the crisis in favor of the federal government undermined the nullification doctrine and underscored the primacy of the national government, establishing a precedent that states could not unilaterally resist federal legislation.124
