Guy Fawkes' Catholic Gunpowder Plot - an attempt to blow up England's Houses of Parliament and Protestant King James I on November 5th 1605 - left an enduring legacy in England, though clearly not the one Fawkes had hoped for. Celebrated annually as Guy Fawkes Night/Bonfire Night throughout Great Britain over 400 years later.
Guy Fawkes Day: "Please to remember the fifth of November." Fawkes, along with a group of catholic conspirators, planned to blow up the House of Lords with gunpowder in order to kill the Protestant king James. Their plot was discovered and failed, but was not forgotten.
