U.S. President John Quincy Adams signs the Tariff of 1828 into law, sparking outrage in the South and leading to the Nullification crisis.

John Quincy Adams was the sixth president of the United States, serving from 1825 to 1829. He previously served as the eighth United States secretary of state from 1817 to 1825. During his long diplomatic and political career, Adams served as an ambassador and also as a member of the United States Congress representing Massachusetts in both chambers. He was the eldest son of John Adams, who served as the second president of the United States from 1797 to 1801, and First Lady Abigail Adams. Initially a Federalist like his father, he won election to the presidency as a member of the Democratic-Republican Party, and later, in the mid-1830s, became affiliated with the Whig Party.

The Tariff of 1828 was a very high protective tariff that became law in the United States on May 19, 1828. It was a bill designed to fail in Congress because it was seen by free trade supporters as hurting both industry and farming, but it passed anyway. The bill was vehemently denounced in the South and escalated to a threat of civil war in the nullification crisis of 1832–33. The tariff was replaced in 1833, and the crisis ended. It was called the "Tariff of Abominations" by its Southern detractors because of the effects it had on the Southern economy. It set a 38% tax on some imported goods and a 45% tax on certain imported raw materials.

The nullification crisis was a sectional political crisis in the United States in 1832 and 1833, during the presidency of Andrew Jackson, which involved a confrontation between the state of South Carolina and the federal government. It ensued after South Carolina declared the federal Tariffs of 1828 and 1832 unconstitutional and therefore null and void within the sovereign boundaries of the state.
