The Nullification Crisis was based on southern concerns that tariffs were preventing the South from industrializing as fast as the North.

Explanation:

The Nullification Crisis was a constitutional conflict in the United States that took place in 1832-33 between President Andrew Jackson and the State of South Carolina.

The cause of the crisis were the tariff laws of 1828 and 1832, which introduced high protective tariffs for industrial products in favor of the mainly growing industry in the North, and encountered resistance in the agricultural South. Resistance to tariffs and a political tradition that saw the Union as an alliance of sovereign states led to the popularity of South Carolina's doctrine of nullification. According to it, a state was allowed to nullify laws that it considered unconstitutional, thereby invalidating them. Following the passage of the Tariff Act of 1832, South Carolina, under the leadership of John C. Calhoun, Robert Young Hayne, James Hamilton, Jr. and other politicians, put this doctrine into practice. The state decided to suspend the tariff laws of 1828 and 1832 from the spring of 1833 and threatened secession from the United States if the central government wanted to enforce the laws by force. President Andrew Jackson, who was skeptical of customs duties, responded by calling for further tariff reductions by Congress, but at the same time publicly attacking South Carolina and the doctrine of nullification and threatening to use military means. The slave-holding countries of the South did not support South Carolina in their nullification, but made it clear they wanted to prevent a war in any case. Under the leadership of Henry Clay, a compromise was finally found. He envisaged further lowering of tariffs and the withdrawal of South Carolina's nullification.
