In 1832 South Carolina threatened to succeed from the union over what issue

The Nullification Crisis was a United States sectional political crisis in 1832-33, during the presidency of Andrew Jackson, which involved a confrontation between South Carolina and the federal government. It ensued after South Carolina declared that the federal Tariffs of 1828 and 1832 were unconstitutional and therefore null and void within the sovereign boundaries of the state.

In November 1832 the Nullification Convention met. The convention declared that the tariffs of 1828 and 1832 were unconstitutional and unenforceable within the state of South Carolina after February 1, 1833. They said that attempts to use force to collect the taxes would lead to the state's secession.
