Guy Fawkes Night, also known as Guy Fawkes Day, Bonfire Night and Firework Night, is an annual commemoration observed on 5 November, primarily in the United Kingdom. Its history begins with the events of 5 November 1605, 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 and fireworks around London.
It is celebrated as an annual public day of thanksgiving for the plot's failure.
