James Knox Polk (November 2, 1795 – June 15, 1849) was the 11th president of the United States, serving from 1845 to 1849. He previously was Speaker of the House of Representatives (1835–1839) and governor of Tennessee (1839–1841). Jackson was a family friend to both the Polks and the Childresses—there is evidence Sarah Polk and her siblings called him 'Uncle Andrew'—and James Polk quickly came to support his presidential ambitions for 1824. When the Tennessee Legislature deadlocked on whom to elect as U.S. senator in 1823 (until 1913, legislators, not the people, elected senators), Jackson's name was placed in nomination.
