The Anti-Masonic Party was the earliest third party in the United States. Formally a single-issue party, it strongly opposed Freemasonry in the United States. It was active from the late 1820s, especially in the Northeast, and later attempted to become a major party by expanding its platform to take positions on other issues. It declined quickly after 1832 as most members joined the new Whig Party; it disappeared after 1838. The party was founded following the disappearance of William Morgan, a former Mason who had become a prominent critic of the Masonic organization. Many believed that Masons had murdered Morgan for speaking out against Masonry and subsequently many churches and other groups condemned Masonry. As many Masons were prominent businessmen and politicians, the backlash against the Masons was also a form of anti-elitism. The Anti-Masons purported that Masons posed a threat to American republicanism by secretly trying to control the government. Furthermore, there was a strong fear that Masonry was hostile to Christianity. Mass opposition to Masonry eventually coalesced into a political party. Before and during the presidency of John Quincy Adams, there was a period of political realignment. The Anti-Masons emerged as an important third-party alternative to Andrew Jackson's Democrats and Adams' National Republicans. In New York, the Anti-Masons supplanted the National Republicans as the primary opposition to the Democrats. After experiencing unexpected success in the 1828 elections, the Anti-Masons adopted positions on other issues, most notably support for internal improvements and a protective tariff. Several Anti-Masons, including William A. Palmer and Joseph Ritner, won election to prominent positions. In states such as Pennsylvania and Rhode Island, the party controlled the balance of power in the state legislature and provided crucial support to candidates for the United States Senate. In 1831, the party held the first presidential nominating convention, a practice that was subsequently adopted by all major parties. Delegates chose former U.S. Attorney General William Wirt as their standard bearer in the 1832 presidential election; Wirt won 7.8% of the popular vote and carried Vermont. As the 1830s progressed, many of the Anti-Masonic Party's supporters joined the Whig Party, which sought to unite those opposed to the policies of President Jackson. The Anti-Masons brought with them an intense distrust of politicians and a rejection of unthinking party loyalty, together with new campaign techniques to whip up excitement among the voters.
