Pope Night (also called Pope's Night, Pope Day, or Pope's Day) was an anti-Catholic holiday celebrated annually on November 5 in the colonial United States. It evolved from the British Guy Fawkes Night, which commemorates the failure of the Gunpowder Plot of 1605. Pope Night was most popular in the seaport towns of New England, especially in Boston, where it was an occasion for drinking, rioting, and anti-elite protest by the working class.
