Explanation: The Tariff of 1828 was a very high protective tariff that became law in the United States in May 1828. It was a bill designed to not pass Congress because it hurt both industry and farming, but surprisingly it passed. The bill was vehemently denounced in the South and escalated to a threat of civil war in the Nullification crisis of 1832-1833. The tariff was replaced in 1833 and the crisis ended. It was called "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.[1]
