Martin Van Buren (born December 5, 1782 – died July 24, 1862) was an American politician who served as the eighth President of the United States (1837–41). A member of the Democratic Party, he served in a number of senior roles, including eighth Vice President (1833–37) and tenth Secretary of State (1829–31), both under Andrew Jackson. Van Buren's inability as president to deal with the deep economic depression following the Panic of 1837 and with the surging Whig Party led to his defeat in the 1840 election by presidential candidate William Henry Harrison of the Whig Party.

In the 1840 election, Van Buren, the incumbent president, was renominated in Baltimore in May 1840. The Democractic Party refused to renominate his sitting vice president, Richard Mentor Johnson, but could not agree on an alternative, and so nominated no one. Because of this, Van Buren had to run without a vice presidential running mate.
