The Whig Party was a political party of the United States during the era of Jacksonian democracy. Considered integral to the Second Party System and operating from the early 1830s to the mid-1850s, the party was formed in opposition to the policies of President Andrew Jackson and his Democratic Party. In particular, the Whigs supported the supremacy of Congress over the presidency and favored a program of modernization and economic protectionism. This name was chosen to echo the American Whigs of 1776, who fought for independence and because "Whig" was then a widely recognized label of choice for people who saw themselves as opposing tyranny. The Whig Party counted among its members such national political luminaries as Daniel Webster, William Henry Harrison, and their preeminent leader, Henry Clay of Kentucky. In addition to Harrison, the Whig Party also nominated war heroes generals Zachary Taylor and Winfield Scott. Abraham Lincoln was the chief Whig leader in frontier Illinois.
In its two decades of existence, the Whig Party saw two of its candidates, William Henry Harrison and Zachary Taylor, elected president. Both, however, died in office. John Tyler became president after Harrison's death but was expelled from the party. Millard Fillmore, who became president after Taylor's death, was the last Whig to hold the nation's highest office.
The party was ultimately destroyed by the question of whether to allow the expansion of slavery to the territories. With deep fissures in the party on this question, the anti-slavery faction successfully prevented the renomination of its own incumbent President Fillmore in the 1852 presidential election; instead, the party nominated General Winfield Scott. Most Whig party leaders thereupon quit politics (as Lincoln did temporarily) or changed parties. The northern voter base mostly joined the new Republican Party. By the 1856 presidential election, the party was virtually defunct. In the South, the party vanished, but as Thomas Alexander has shown, Whiggery as a policy orientation persisted for decades and played a major role in shaping the modernizing policies of the state governments during Reconstruction after 1865.
