The Whig Party was a political party in the United States during the middle of the 19th century. 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 terms. Other influential party leaders that were members of the Whigs include Henry Clay, Daniel Webster, William Seward, John J. Crittenden, and John Quincy Adams. The Whig base of support was centered among entrepreneurs, professionals, planters, social reformers, devout Protestants, and the emerging urban middle class. It had much less backing from poor farmers and unskilled workers.
