Rye House Plot, 1683, conspiracy to assassinate Charles II of England and his brother James, duke of York (later James II), as they passed by Rumbold's Rye House in Hertfordshire on the road from Newmarket to London. However, the king did not make the journey on the expected day; the plot, an offshoot of earlier insurrection plots hatched by the 1st earl of Shaftesbury, was revealed. Although the actual conspirators were only minor figures, the great Whig leaders Lord William Russell and Algernon Sidney were executed on flimsy evidence of guilt by association.

Gunpowder Plot, conspiracy to blow up the English Parliament and King James I on Nov. 5, 1605, the day set for the king to open Parliament. It was intended to be the beginning of a great uprising of English Catholics, who were distressed by the increased severity of penal laws against the practice of their religion. The conspirators, who began plotting early in 1604, expanded their number to a point where secrecy was impossible. They included Robert Catesby, John Wright, and Thomas Winter, the originators, Christopher Wright, Robert Winter, Robert Keyes, Guy Fawkes, a soldier who had been serving in Flanders, Thomas Percy, John Grant, Sir Everard Digby, Francis Tresham, Ambrose Rookwood, and Thomas Bates. Percy hired a cellar under the House of Lords, in which 36 barrels of gunpowder, overlaid with iron bars and firewood, were secretly stored. The conspiracy was brought to light through a mysterious letter received by Lord Monteagle, a brother-in-law of Tresham, on Oct. 26, urging him not to attend Parliament on the opening day. The 1st earl of Salisbury and others, to whom the plot was made known, took steps leading to the discovery of the materials and the arrest of Fawkes as he entered the cellar. Other conspirators, overtaken in flight or seized afterward, were killed outright, imprisoned, or executed. Among those executed was Henry Garnett, the superior of the English Jesuits, who had known of the conspiracy. While the plot was the work of a small number of men, it provoked hostility against all English Catholics and led to an increase in the harshness of laws against them. Guy Fawkes Day, Nov. 5, is still celebrated in England with fireworks and bonfires, on which effigies of the conspirator are burned.

(1683) In English history, an alleged Whig conspiracy to assassinate Charles II because of his pro-Catholic policies. The plot drew its name from Rye House at Hoddesdon, Hertfordshire, near the road where Charles was supposed to be killed as he traveled from a horse meet. The king's unexpected early departure supposedly foiled the plot, which was later revealed by an informer. The facts remained cloudy, but the main plotters included the duke of Monmouth, Lord William Russell, Algernon Sidney (1622–83), and Sir Thomas Armstrong. The last three were tried, convicted of treason, and beheaded.

(1678) In English history, a fictitious but widely believed rumour that Jesuits planned to assassinate Charles II and replace him with his brother, the Catholic duke of York (later James II). The rumour was fabricated by Titus Oates, who gave a sworn deposition of his “evidence” to a London justice of the peace. When the latter was found murdered, a panic among the people was followed by accusations and trials, leading to the execution of about 35 innocent people. When Oates was finally discredited, the panic subsided.

(1605) Conspiracy by English Roman Catholic zealots to blow up Parliament and kill James I. Angered by James's refusal to grant more religious toleration to Catholics, a group of conspirators led by Robert Catesby (1573–1605) recruited Guy Fawkes to their plot. One member warned his brother-in-law Lord Monteagle not to attend Parliament on the appointed day (November 5, 1605), and Monteagle alerted the government. Fawkes was arrested in a rented cellar under the palace at Westminster, where he had concealed 20 barrels of gunpowder. Under torture, he revealed the names of the conspirators, and they were all either killed while resisting arrest or executed in 1606. The plot bitterly intensified Protestant suspicions of Catholics.
