The issue was the 1832 nullification Crisis. It was caused due to an economic recession that affected the United States and especially South Carolina during the decade of the 1820s. The 1828 Tariff was used by Martin Van Buren for political reasons in order to gain support of many industrialist northern states.
However, it greatly hurt South Carolina’s economy which depended on the products taxed by such tariff. A compromise was offered to the state with the revised Tariff of 1832 but it was rejected by it. South Carolina declared the Tariff unconstitutional and null and void and declared its willingness to resist by force and secede if necessary. The Compromise Tariff of 1833 solved the issue.
