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.

Henry Clay played a pivotal role in resolving the Nullification Crisis by engineering the passage of the Compromise Tariff of 1833.12

During the crisis, South Carolina had declared federal tariffs null and void and threatened to secede from the Union, while President Andrew Jackson prepared to use military force to uphold federal law through the Force Bill. Recognizing the danger of a serious armed confrontation, Clay—a member of the "Great Triumvirate"—proposed a legislative solution that would gradually lower tariff rates over the course of 10 years.132

By successfully securing the passage of this compromise, Clay provided a path for South Carolina to rescind its ordinance of nullification, thereby de-escalating the conflict and preventing a potential civil war.23
