Where did the Anti-Masonic Movement gain the most support?

The Anti-Masonic Movement gained the most significant traction in New York. The movement was ignited in 1826 by the disappearance of William Morgan, a bricklayer in western New York who allegedly intended to reveal Masonic secrets. This event sparked widespread indignation and suspicion towards the Masons, leading to the creation of the Anti-Masonic Party.1

The uproar quickly spread from New York into New England and the Mid-Atlantic states. Anti-Masonic candidates found success in state and local elections, and newspapers dedicated to the cause flourished in this heated political climate. The Anti-Masonic Party held its first national convention in Baltimore, Maryland, in September 1831, and nominated William Wirt for president.1
