On November 5, 1844, Democratic candidate James K. Polk defeated Whig Party candidate Henry Clay to become the eleventh president of the United States. Democrats nominated Polk as the nation's first "dark horse" candidate on the ninth ballot of the Democratic National Convention, after former president Martin Van Buren lost his bid because of his opposition to annexing Texas, a position deemed unacceptable by Southerners and by former president Andrew Jackson.
Told of his nomination in a letter, Polk penned his reply: "It has been well observed that the office of President of the United States should neither be sought nor declined. I have never sought it, nor should I feel at liberty to decline it, if conferred upon me by the voluntary suffrages of my Fellow Citizens." Read Polk's acceptance letter in full in the American Memory collection Words and Deeds in American History: Selected Documents Celebrating the Manuscript Division's First 100 Years. News of his nomination was spread by the Morse telegraph system, which had just been invented.
