The Whig Party was a political party active in the middle of the 19th century in the United States. Alongside the slightly larger Democratic Party, it was one of the two major parties in the United States between the late 1830s and the early 1850s as part of the Second Party System. Four presidents were affiliated with the Whig Party for at least part of their respective terms. Other influential party leaders include Henry Clay, Daniel Webster, William Seward, John J. Crittenden, John Quincy Adams, and Truman Smith.
