What was the Gunpowder Plot of 1605 in British history?

A small number of radical Catholics placed barrels of gunpowder in a cellar of the Parliament House。The immediate result of the plot was the execution of Fawkes and the imposition of severe anti-Catholic laws。The long-term result has been an annual celebration on fireworks and bonfire on which Guy Fawkes was burnt in effigy。The celebration was to remind the English people that there was the danger of Catholic restoration。
