Overview
John Caldwell Calhoun (; March 18, 1782March 31, 1850) was an American statesman and political theorist who served as the seventh vice president of the United States from 1825 to 1832. Born in South Carolina, he adamantly defended American slavery and sought to protect the interests of white Southerners. Calhoun began his political career as a nationalist, modernizer and proponent of a strong federal government and protective tariffs. In the late 1820s, his views changed radically, and he became a leading proponent of states' rights, limited government, nullification, and opposition to high tariffs. Calhoun saw Northern acceptance of those policies as a condition of the South's remaining in the Union. His beliefs and warnings heavily influenced the South's secession from the Union in 1860 and 1861. He was the first of two vice presidents to resign from the position, the second being Spiro Agnew, who resigned in 1973.
Calhoun began his political career with election to the House of Representatives in 1810. As a prominent leader of the war hawk faction, he strongly supported the War of 1812. Calhoun served as Secretary of War under President James Monroe and, in that position, reorganized and modernized the War Department. He was a candidate for the presidency in the 1824 election. After failing to gain support, Calhoun agreed to be a candidate for vice president. The Electoral College elected him vice president by an overwhelming majority. He served under John Quincy Adams and continued under Andrew Jackson, who defeated Adams in the election of 1828, making Calhoun the most recent U.S. vice president to serve under two different presidents.
He had a difficult relationship with Jackson, primarily because of the Nullification Crisis and the Petticoat affair. In contrast with his previous nationalist sentiments, Calhoun vigorously supported South Carolina's right to nullify federal tariff legislation that he believed unfairly favored the North, which put him into conflict with Unionists such as Jackson. In 1832, with only a few months remaining in his second term, Calhoun resigned as vice president and entered the Senate. He sought the Democratic Party nomination for the presidency in 1844 but lost to surprise nominee James K. Polk, who won the general election.
