The document discusses United States tariffs and nullification between 1828 and 1842. It summarizes the Tariff of Abominations in 1828, South Carolina's opposition and passage of nullification laws, the Tariff of 1832 which lessened duties but did not satisfy Southerners, President Jackson's proclamation against nullification which led to compromise in the Tariff of 1833, and ongoing tensions as Northern interests pushed for higher tariffs while the South advocated for lower duties and states' rights.
