Bonfire Night is also known as Fireworks' Night or Guy Fawkes' Night. It's a British tradition dating back to the Gunpowder Plot of 1605 when Catholic conspirator Guy Fawkes tried to blow up the Houses of Parliament and King James I. It is still customary for the cellars in the Houses of Parliament to be searched by the Yeoman of the Guard before each State Opening of Parliament. The anniversary of Fawkes' arrest on 5 November is celebrated each year with organised or informal fireworks displays and bonfire parties. Effigies of Guy Fawkes 'the guy' are often burned on top of the bonfires.
