John Quincy Adams signed a law that established a high tariff and strongly hurt southern economy. Southerners called it the "tariff of abominations." Jackson did not reduce it when he was in office.
Jackson signed a tariff that helped ease the tension in the issue, but it wasn't enough for satisfaction. John C. Calhoun, the vice president, left to go to the senate and fight against the tariff.
Calhoun led politicians in south Carolina to organize the ordinance of nullification, meaning they would refuse to obey the law. Some even wanted to secede.
Jackson responded by issuing the force bill, meaning he could use military force against south Carolina if they did not cooperate. This way, their threat of secession could not be executed.
South Carolina agreed to compromise on the new tariff to avoid issues. Despite this, they still nullified the force bill. Jackson considerably won, but secession and nullification issues weren't settled.
