Guy Fawkes Day is observed on November 5th each year. It commemorates the failure of the Gunpowder Plot of 1605, when Guy Fawkes and fellow conspirators plotted to blow up the Houses of Parliament in London. The first public observance was declared in 1606, and over time the day became known as Guy Fawkes Day or Bonfire Night, with celebrations typically including bonfires and fireworks.
