Guy Fawkes Night (more commonly known as Bonfire Night, Cracker Night and sometimes Fireworks Night) is an annual celebration on the evening of the 5th of November. It celebrates the foiling of the Gunpowder Plot of the 5th of November 1605 in which a number of Roman Catholic conspirators, including Guy Fawkes, attempted to blow up the Houses of Parliament in London, England.

It is primarily marked in the United Kingdom where it was compulsory, by Royal Decree, to celebrate the deliverance of the King until 1859, but also in former British colonies including New Zealand, parts of Canada, and parts of the British Caribbean. Bonfire Night was also common in Australia until the 1980s , but it was held on the Queen's Birthday long weekend in June some states (eg New South Wales) and Nov 5th in others (eg Victoria). The event occurred in England some 102 years before the Act Of Union between England and Scotland. Festivities are centred around the use of fireworks and the lighting of bonfires.
