John C. Breckinridge

John Cabell Breckinridge (January 16, 1821 – May 17, 1875) was an American politician who served as the 14th vice president of the United States, with President James Buchanan, from 1857 to 1861, and as a general in the Confederate Army during the American Civil War. Assuming office at the age of 36, Breckinridge is the youngest vice president in U.S. history. He was also the Southern Democratic candidate in the 1860 presidential election, losing to antislavery Republican candidate Abraham Lincoln.

Breckinridge was born near Lexington, Kentucky, to a prominent local family. After serving as a noncombatant during the Mexican–American War, he was elected as a Democrat to the Kentucky House of Representatives in 1849, where he took a pro-slavery stance. Elected to the U.S. House of Representatives in 1851, he allied with Stephen A. Douglas in support of the Kansas–Nebraska Act. After reapportionment in 1854 made his re-election unlikely, he declined to run for another term. He was nominated for vice president at the 1856 Democratic National Convention to balance a ticket headed by James Buchanan. The Democrats won the election, but Breckinridge had little influence with Buchanan, and as presiding officer of the Senate, could not express his opinions in debates. He joined Buchanan in supporting the proslavery Lecompton Constitution for Kansas, which led to a split in the Democratic Party. In 1859, he was elected to succeed Senator John J. Crittenden at the end of Crittenden's term in 1861.
