Andrew Pickens Calhoun was born October 15, 1812, in Abbeville District SC and died March 16, 1865, at "Fort Hill," his plantation home in SC. Fort Hill is also known as John C. Calhoun Mansion and Library, Clemson University campus, Clemson. In 1835, A.P. Calhoun removed with his family and numerous slaves to Marengo County. He built a large log house, where his children were born, and named his home "Tulip Hill." A.P. Calhoun was son of John Calhoun. John C. Calhoun spent his entire career working for the U.S. government in a variety of high offices. He served as the seventh Vice President of the United States, first under John Quincy Adams (1825-1829) and then under Andrew Jackson (1829-1832), but resigned the Vice Presidency to enter the U.S. Senate, where he had more power. He was an outspoken proponent of slavery and still influential during the Civil War even though he died a decade before.
