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 . </P> <P> The U.S. suffered an economic downturn throughout the 1820s, and South Carolina was particularly affected . Many South Carolina politicians blamed the change in fortunes on the national tariff policy that developed after the War of 1812 to promote American manufacturing over its European competition . The controversial and highly protective Tariff of 1828 (known to its detractors as the "Tariff of Abominations") was enacted into law during the presidency of John Quincy Adams . The tariff was opposed in the South and parts of New England . By 1828, South Carolina state politics increasingly organized around the tariff issue . Its opponents expected that the election of Jackson as President would result in the tariff being significantly reduced . When the Jackson administration failed to take any actions to address their concerns, the most radical faction in the state began to advocate that the state itself declare the tariff null and void within South Carolina . In Washington, an open split on the issue occurred between Jackson and Vice President John C. Calhoun, a native South Carolinian and the most effective proponent of the constitutional theory of state nullification . </P>
