The Gunpowder Plot of 1605, in earlier centuries often called the Gunpowder Treason Plot or the Jesuit Treason, was a failed assassination attempt against King James I of England and VI of Scotland 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 England's Parliament on 5 November 1605, as the prelude to a popular revolt in the Midlands during which James's nine-year-old daughter, Princess 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 Wright, Thomas Wintour, Thomas Percy, Guy Fawkes, Robert Keyes, Thomas Bates, Robert Wintour, Christopher Wright, John Grant, Sir Ambrose Rookwood, Sir Everard Digby and Francis Tresham. Fawkes, who had 10 years of military experience fighting in the Spanish Netherlands in 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 26 October 1605. During a search of the House of Lords at about midnight on 4 November 1605, Fawkes was discovered guarding 36 barrels of gunpowder—enough to reduce the House of Lords to rubble—and arrested. Most of the conspirators fled from London as they learnt 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 27 January 1606, eight of the survivors, including Fawkes, were convicted and sentenced to be hanged, drawn and quartered.
Details of the assassination attempt were allegedly known by the principal Jesuit of England, Father Henry Garnet. Although Garnet was convicted and sentenced to death, doubt has since been cast on how much he really knew of the plot. As its existence was revealed to him through confession, Garnet was prevented from informing the authorities by the absolute confidentiality of the confessional. Although anti-Catholic legislation was introduced soon after the plot's discovery, many important and loyal Catholics retained high office during King James I's reign. 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 have evolved into the Bonfire Night of today.
The surviving conspirators of the Gunpowder Plot were arraigned in Westminster Hall on January 27, 1606. Seven of the prisoners were taken from the Tower to the Star Chamber by barge. Thomas Bates, who was considered lower class, was brought from the Gatehouse Prison. Some of the prisoners were reportedly despondent, but others were nonchalant, even smoking tobacco. The King and his family, hidden from view, were among the many who watched the trial. The Lords Commissioners present were the Earls of Suffolk, Worcester, Northampton, Devonshire, and Salisbury. Sir John Popham was Lord Chief Justice, Sir Thomas Fleming was Lord Chief Baron of the Exchequer, and two Justices, Sir Thomas Walmsley and Sir Peter Warburton, sat as Justices of the Common Pleas. The list of traitors' names was read aloud, beginning with those of the priests: Henry Garnet, Oswald Tesimond, and John Gerard.
The first to speak was the Speaker of the House of Commons (later Master of the Rolls), Sir Edward Philips, who described the intent behind the plot in lurid detail. He was followed by the Attorney-General Sir Edward Coke, who began with a long speech—the content of which was heavily influenced by Salisbury—that included a denial that the King had ever made any promises to the Catholics. William Parker, 4th Baron Monteagle's part in the discovery of the plot was welcomed, and denouncements of the 1603 mission to Spain featured strongly. Guy Fawkes's protestations that Gerard knew nothing of the plot were omitted from Coke's speech. The foreign powers, when mentioned, were accorded due respect, but the priests were accursed, their behavior analyzed and criticized wherever possible. There was little doubt, according to Coke, that the plot had been invented by the Jesuits. Garnet's meeting with Robert Catesby, at which the former was said to have absolved the latter of any blame in the plot, was proof enough that the Jesuits were central to the conspiracy; according to Coke the Gunpowder Plot would always be known as the Jesuit Treason. Coke spoke with feeling of the probable fate of the Queen and the rest of the King's family, and of the innocents who would have been caught up in the explosion.
Each of the condemned, said Coke, would be drawn backwards to his death, by a horse, his head near the ground. He was to be "put to death halfway between heaven and earth as unworthy of both". His genitals would be cut off and burnt before his eyes, and his bowels and heart then removed. Then he would be decapitated, and the dismembered parts of his body displayed so that they might become "prey for the fowls of the air". Confessions and declarations from the prisoners were then read aloud, and finally the prisoners were allowed to speak. Rookwood claimed that he had been drawn into the plot by Catesby, "whom he loved above any worldy man". Thomas Wintour begged to be hanged for himself and his brother, so that his brother might be spared. Fawkes explained his not guilty plea as ignorance of certain aspects of the indictment. Keyes appeared to accept his fate, Bates and Robert Wintour begged for mercy, and Grant explained his involvement as "a conspiracy intended but never effected". Only Digby, tried on a separate indictment, pleaded guilty, insisting that the King had reneged upon promises of toleration for Catholics, and that affection for Catesby and love of the Catholic cause mitigated his actions. He sought death by the axe and begged mercy from the King for his young family. His defense was in vain; his arguments were rebuked by Coke and Northumberland, and along with his seven co-conspirators, he was found guilty by the jury of high treason. Digby shouted "If I may but hear any of your lordships say, you forgive me, I shall go more cheerfully to the gallows." The response was short: "God forgive you, and we do."
Garnet may have been questioned on as many as 23 occasions. His response to the threat of the rack was "Minare ista pueris [Threats are only for boys]", and he denied having encouraged Catholics to pray for the success of the "Catholic Cause". His interrogators resorted to the forgery of correspondence between Garnet and other Catholics, but to no avail. His jailers then allowed him to talk with another priest in a neighbouring cell, with eavesdroppers listening to every word. Eventually Garnet let slip a crucial piece of information, that there was only one man who could testify that he had any knowledge of the plot. Under torture Garnet admitted that he had heard of the plot from fellow Jesuit Oswald Tesimond, who had learnt of it in confession from Catesby. Garnet was charged with high treason and tried in the Guildhall on 28 March, in a trial lasting from 8 am until 7 pm. According to Coke, Garnet instigated the plot: "[Garnet] hath many gifts and endowments of nature, by art learned, a good linguist and, by profession, a Jesuit and a Superior as indeed he is Superior to all his predecessors in devilish treason, a Doctor of Dissimulation, Deposing of Princes, Disposing of Kingdoms, Daunting and deterring of subjects, and Destruction." Garnet refuted all the charges against him, and explained the Catholic position on such matters, but he was nevertheless found guilty and sentenced to death.
