At Westminster in London, Guy Fawkes, a chief conspirator in the plot to blow up the British Parliament building, jumps to his death moments before his execution for treason. On the eve of a general parliamentary session scheduled for November 5, 1605, Sir Thomas Knyvet, a justice of the peace, found Guy Fawkes lurking in a cellar of the Parliament building. Fawkes was detained and the premises thoroughly searched. Nearly two tons of gunpowder were found hidden within the cellar. In his interrogation, Fawkes revealed that he was a participant in an English Catholic conspiracy organized by Robert Catesby to annihilate England's entire Protestant government, including King James I. After a brief trial, Guy Fawkes was sentenced to be hanged, drawn, and quartered in London. On January 31 1606, Fawkes was called to meet his fate. While climbing to the hanging platform, however, he jumped from the ladder and broke his neck, dying instantly. In remembrance of the Gunpowder Plot, Guy Fawkes Day is celebrated across Great Britain every year on November 5th. As dusk falls in the evening, villagers and city dwellers across Britain light bonfires, set off fireworks, and burn an effigy of Guy Fawkes, celebrating his failure to blow up Parliament and James I.
