The Gunpowder Plot of 1605, […] often called the Gunpowder Treason Plot or the Jesuit Treason [in earlier centuries], was a failed assassination attempt against King James I by a group of provincial English Catholics led by Robert Catesby.
The plan was to blow up the House of Lords during the State Opening of Parliament on [November] 5, 1605, as the prelude to a popular revolt in the Midlands, during which James’s nine-year-old daughter, Elizabeth, was to be installed as the Catholic head of state. Catesby may have embarked on the scheme after hopes of securing greater religious tolerance under King James had faded, leaving many English Catholics disappointed. His fellow plotters were John and Christopher Wright, Robert and Thomas Wintour, Thomas Percy, Guy Fawkes, Robert Keyes, Thomas Bates, John Grant, Ambrose Rookwood, Sir Everard Digby and Francis Tresham. Fawkes, who had 10 years of military experience fighting in the Spanish Netherlands in the failed suppression of the Dutch Revolt, was given charge of the explosives.
The plot was revealed to the authorities in an anonymous letter sent to William Parker, 4th Baron Monteagle, on [October] 26, 1605. During a search of the House of Lords in the evening on [November] 4, 1605, Fawkes was discovered guarding 36 barrels of gunpowder, enough to reduce the House of Lords to rubble, and [was] arrested. Most of the conspirators fled from London as they learned of the plot’s discovery, trying to enlist support along the way. Several made a stand against the pursuing Sheriff of Worcester and his men at Holbeche House […]. [In] the ensuing battle, Catesby was one of those shot and killed. At their trial on [January] 27 1606, four hundred, fifteen years ago, today, eight of the survivors, including Fawkes, were convicted and sentenced to be hanged, drawn and quartered.
The thwarting of the Gunpowder Plot was commemorated for many years afterwards by special sermons and other public events such as the ringing of church bells, which evolved into the British variant of Bonfire Night of today.
