The document summarizes the history and tradition of Bonfire Night celebrations in the United Kingdom. It describes how in 1605, Guy Fawkes and other Catholic conspirators plotted to blow up the Houses of Parliament to protest the persecution of Catholics. The plot was foiled when an anonymous letter warned authorities to search Parliament, where Guy Fawkes was found guarding barrels of gunpowder. Ever since, people in Britain celebrate on November 5th with bonfires, fireworks, and burning effigies of Guy Fawkes to commemorate the foiling of the plot. The tradition spread to British colonies and is still observed today.
