The Gunpowder Plot" was a plan to assassinate the Protestant King James I (James
VI of Scotland) and the members of both houses of the Parliament of England, by exploding Westminster Palace during the formal opening session of the 1605
Parliament, in which the King addressed a joint assembly of both the House
of Lords and the House of Commons. Fawkes was in large part responsible for the later stages of the plan's execution. His activities were detected before the plan's
completion, and following a severe interrogation involving the use of torture and a
trial in Westminster Hall before Judge John Popham, he and his co-conspirators were executed for treason. Fawkes's failure (or the attempt) is remembered by Guy Fawkes Night (also known as Bonfire Night or Fireworks Night) on 5 November
