Gunpowder Plot
Failed 1605 plot to assassinate King James I by English Catholics.
In 1605, a group of English Catholics led by Robert Catesby tried and failed to assassinate King James I of England (also James VI of Scotland). The plot, once commonly called the Gunpowder Treason Plot or the Jesuit Treason, aimed to blow up the House of Lords during the State Opening of Parliament on November 5. After the explosion, the conspirators planned to start a rebellion in the Midlands and install the king’s nine-year-old daughter, Elizabeth, as the new head of state. Historians believe Catesby turned to this scheme after hopes for greater religious tolerance under James faded, leaving many English Catholics disappointed. His fellow conspirators included 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 ten years of military experience fighting in the Spanish Netherlands during the failed suppression of the Dutch Revolt, was put in charge of the explosives.
On October 26, 1605, an anonymous warning letter was sent to William Parker, the 4th Baron Monteagle, a Catholic member of Parliament. He immediately showed it to the authorities. During a search of the House of Lords on the evening of November 4, Fawkes was discovered guarding 36 barrels of gunpowder—enough to reduce the building to rubble—and arrested. Most of the conspirators fled London upon learning the plot had been uncovered, trying to gather support along the way. Several made a final stand against the Sheriff of Worcestershire and his posse at Holbeche House; in the ensuing gunfight, Catesby was shot and killed. At their trial on January 27, 1606, eight surviving conspirators, including Fawkes, were convicted and sentenced to be hanged, drawn, and quartered.
Some details of the assassination attempt were allegedly known by Henry Garnet, the principal Jesuit in England. Though Garnet was convicted of high treason and executed, doubt remains about how much he actually knew. Because the plot was revealed to him in confession, the absolute confidentiality of the confessional prevented him from informing the authorities. Although anti-Catholic legislation was introduced soon after the plot’s discovery, many important and loyal Catholics kept their high offices for the rest of James I’s reign.

Lore & Background
Catesby is suspected by historians to have embarked on the scheme after hopes of greater religious tolerance under James had faded, leaving many English Catholics disappointed. His fellow conspirators 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.
On 26 October 1605, an anonymous letter of warning was sent to William Parker, 4th Baron Monteagle, a Catholic member of Parliament, who immediately showed it to the authorities. During a search of the House of Lords on the evening of 4 November, Fawkes was discovered guarding 36 barrels of gunpowder—enough to reduce the House of Lords to rubble—and arrested. Hearing that the plot had been discovered, most of the conspirators fled from London while trying to enlist support along the way. Several made a last stand against the pursuing Sheriff of Worcestershire and a posse of his men at Holbeche House; in the ensuing gunfight Catesby was one of those shot and killed. At their trial on 27 January 1606, eight of the surviving conspirators, including Fawkes, were convicted and sentenced to be hanged, drawn and quartered.
Reader's Guide
The Gunpowder Plot represents a pivotal moment in English history, illustrating the deep religious tensions following the Protestant Reformation and the Elizabethan Religious Settlement. Although the plot failed, its discovery led to the introduction of anti-Catholic legislation soon after, though many important and loyal Catholics remained in high office during the rest of King James I's reign. The thwarting of the 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. Some details of the assassination attempt were allegedly known by the principal Jesuit of England, Henry Garnet. Although Garnet was convicted of high treason and put to death, doubt has been cast on how much he really knew. As the plot's existence was revealed to him through confession, Garnet was prevented from informing the authorities by the absolute confidentiality of the confessional. The plot's legacy endures in annual celebrations and in the figure of Guy Fawkes as a symbol of rebellion.
