Guy Fawkes Night [SEP] Introduction
Guy Fawkes Night, also known as Guy Fawkes Day, Bonfire Night and Fireworks Night, is an annual commemoration observed on 5 November, primarily in the United Kingdom. Its history begins with the events of 5 November 1605 O.S., when Guy Fawkes, a member of the Gunpowder Plot, was arrested while guarding explosives the plotters had placed beneath the House of Lords. Celebrating the fact that King James I had survived the attempt on his life, people lit bonfires around London; and months later, the introduction of the Observance of 5th November Act enforced an annual public day of thanksgiving for the plot's failure.
