Answer:the Nullification Crisis
Step-by-step explanation:
The Nullification Crisis was a conflict over states' rights. Congress enacted tariffs in 1828 and 1832 on imported goods in order to protect American factories. South Carolina decided to declare the tariffs null and void within their state, which meant they refused to follow the federal law. South Carolina thought that the tariffs were unfair because they were forced to pay higher prices for goods. South Carolina threatened to secede if the government tried to enforce the law, and President Jackson was getting ready to send troops to South Carolina. Henry Clay introduced a new tariff, which lowered the tax rates over a few years, and South Carolina did not secede.
