On this date in 1782, John Caldwell Calhoun was born in South Carolina. He began his political career in 1810, when he was elected to the House of Representatives, where he served until 1817, when James Monroe appointed him the 10th US Secretary of War. He served until March 4, 1825, when he took office as the seventh Vice President of the United States. At the time, he was the second youngest Vice President, and is currently the sixth youngest to hold the office. Following the election of 1828, he became the second (and to date, the last) Vice President to serve under two different Presidents (John Quincy Adams and Andrew Jackson). Calhoun and Jackson disagreed during Jackson's first term of office, and Jackson dropped him from the ticket in favor of Martin Van Buren. Calhoun was elected to the US Senate in 1832, and became the first (now first of only two) Vice President to resign, when he left office on December 28, 1832, to take his seat in the Senate. Calhoun represented South Carolina in the Senate from December 29, 1832, until March 3, 1843, when he became the 16th US Secretary of State. He served John Tyler in that office for just under a year, and then was re-elected to the Senate, which seat he held until his death in March 1850.
