The Popish Plot was a fictitious conspiracy concocted by Titus Oates that between 1678 and 1681 gripped the Kingdoms of England and Scotland in anti-Catholic hysteria. Oates alleged that there existed an extensive Catholic conspiracy to assassinate Charles II, accusations that led to the execution of at least 22 men and precipitated the Exclusion Bill Crisis. Eventually Oates' intricate web of accusations fell apart, leading to his arrest and conviction for perjury.
Development of English anti-Catholicism 
The fictitious Popish Plot must be understood against the background of the English Reformation and the subsequent development of a strong anti-Catholic sentiment among the mostly Protestant population of England.
The English Reformation began in 1533, when King Henry VIII (1509–1547) sought an annulment of his marriage to Catherine of Aragon to marry Anne Boleyn. As the Pope would not grant this, Henry broke away from Rome and took control of the Church in England. Later, he had the monasteries dissolved, causing opposition in the still largely Catholic nation. Under Henry's son, Edward VI (1547–1553), the Church of England was transformed into a strictly Protestant body, with many remnants of Catholicism suppressed. Edward was succeeded by his half-sister Mary I of England (1553–1558), daughter of Henry VIII and Catherine. She was a Catholic and returned the Church in England to union with the Holy See. Mary tinged her policy by two unpopular actions: she married her cousin, King Philip II of Spain, where the horrors of the Inquisition continued, and had 300 Protestants burned at the stake, causing many Englishmen to associate Catholicism with the involvement of foreign powers and religious persecution. Even though Catholics were sometimes persecuted by Protestant rulers later on, the ferocity that marked Mary's reign and the Inquisition never existed, and it was Catholicism that was seen as the persecuting religion. Historian John Philipps Kenyon remarked "Nor was there any doubt as to what would happen if Catholics seized control: all good Protestants would burn."
Mary was succeeded by her Protestant half-sister, Elizabeth I (1558–1603), who again broke away from Rome and suppressed Catholicism. This and her dubious legitimacy – she was the daughter of Henry VIII and Anne Boleyn – led to Catholic powers not recognising her as Queen and favouring her next relative, the Catholic Mary, Queen of Scots. Elizabeth's reign saw Catholic rebellions like the Rising of the North (1569) as well as plots like the Ridolfi Plot (1571) or the Babington Plot (1586), both intending to kill Elizabeth and replace her with Mary with the help of a Spanish invasion. After the latter, Mary was beheaded in 1587. This and Elizabeth's support of the Dutch Revolt in the Spanish Netherlands – triggered Philip II of Spain attempt invasion with the Spanish Armada (1588). This reinforced the impression that Catholicism was a foreign element while the Armada's failure convinced many Englishmen that God was supportive of Protestantism.
Anti-Catholic sentiment reached new heights in 1605 after the Gunpowder Plot was discovered. Catholic plotters attempted to topple the Protestant regime of King James I by blowing up both King and parliament during the state opening of parliament. However, Guy Fawkes, who was in charge of the explosives, was discovered the night before and the attempt thwarted. The magnitude of the plot – had it succeeded most leading government figures would have been killed in one stroke – convinced many Englishmen that Catholics were devious conspirators who would stop at nothing to have their way, thus making allegations about Catholic plots more believable.
Anti-Catholicism in the 17th century 
Anti-Catholic sentiment was a constant factor in how England perceived the events of the following decades: the Thirty Years War (1618–1648) was seen as an attempt by the Catholic Habsburgs to exterminate German Protestantism. Under the early Stuart Kings fears of Catholic conspiracies were rampant and the policies of Charles I – especially his church policies, which had a decidedly high church bent – were seen as pro-Catholic and likely induced by a Catholic conspiracy headed by Charles' Catholic queen, Henrietta Maria of France. This, together with stories about Catholic atrocities in Ireland in 1641, triggered the English Civil War (1642–1648), which led to the abolition of the monarchy and a decade of Puritan rule, which espoused religious tolerance for most forms of Protestantism but not for Catholicism. The restoration of the monarchy in 1660 under King Charles II brought with it a reaction against all religious dissenters, i.e. all outside the established Church of England. As a result, Catholics felt popular hostility and legal discrimination.
Anti-Catholic hysteria flared up lightly during the reign of Charles II, which saw various disasters such as the Great Plague of London (1665) and the Great Fire of London (1666). After the latter, rumours floated around about arson and the first to be blamed were Catholics, especially the Jesuits. Kenyon remarks, "At Coventry, the townspeople were possessed by the idea that the papists were about to rise and cut their throats ... A nationwide panic seemed likely, and as homeless refugees poured out from London into the countryside, they took with them stories of a kind which were familiar to them in 1678 and 1679."
Anti-Catholicism was fuelled by doubts about the religious allegiance of the King, who had married a Catholic princess, Catherine of Portugal and formed an alliance with France, then the leading Catholic power in Europe, against the Protestant Netherlands. Furthermore, as Charles' brother and heir presumptive, James, Duke of York, had embraced Catholicism. In 1672, Charles issued the Royal Declaration of Indulgence, in which he suspended all penal laws against Catholics and other religious dissenters. This resulted in growing fears by Protestants of increasing Catholic influence in England and led to conflict with parliament during the 1670s. In December 1677 an anonymous pamphlet (possibly by Andrew Marvell) spread alarm in London by suggesting that the Pope planned to change the lawful government of England.
The fictitious Popish Plot unfolded in a very peculiar fashion. Oates and a fanatically anti-Catholic clergyman, Israel Tonge had written a large manuscript that accused the Catholic Church authorities of approving the assassination of Charles II. The Jesuits in England were to carry out the task. The manuscript also named nearly 100 Jesuits and supporters who were supposedly involved in this assassination plot; nothing in the document was ever proven to be true.
Oates slipped a copy of the manuscript into the wainscot of a gallery in the house of the physician Sir Richard Barker, with whom Tonge was living. The following day Tonge claimed to find the manuscript, and showed it to an acquaintance, Christopher Kirkby, who was shocked and decided to inform the King. Kirkby was a chemist and a former assistant in Charles' scientific experiments. On 13 August 1678, whilst Charles was out walking in St. James's Park, the chemist informed him of the plot. Charles was dismissive but Kirkby stated that he knew the names of assassins who planned to shoot the King and, if that failed, the Queen's physician, Sir George Wakeman, would poison him. When the King demanded proof, the chemist offered to bring Tonge who knew of these matters personally. Charles told Kirkby to present Tonge before Thomas Osborne, Lord Danby, Lord High Treasurer, then the most influential of the King's ministers. Tonge then lied to Danby, saying that he had found the manuscript but did not know the author.
As Kenyon points out, the Government took seriously the slightest threat to the King's well-being – the previous summer a Newcastle housewife had been investigated simply for criticising the King's debauched private life. Danby advised the King to order an investigation. Charles II denied the request, maintaining that the entire affair was absurd. He told Danby to keep the events secret so as not to put the idea of regicide into people's minds. However, word of the manuscript spread to the Duke of York, who publicly called for an investigation into the matter. Even Charles admitted that given the sheer number of allegations, he could not be certain that none of them was true, and reluctantly agreed. During the investigation, Oates' name arose. From the first the King was convinced that Oates was a liar, and Oates did not help his case by claiming to have met the Regent of Spain, Don John of Austria. Questioned by the King, who had met Don John in 1656, it became obvious that Oates had no idea what he looked like.The King had a long and frank talk with Paul Barillon, the French Ambassador, in which he made it clear that he did not believe that there was a word of truth in the Plot, and that Oates was " a wicked man"; but by now he had come round to the view that there must be an investigation, particularly with Parliament about to reassemble.
On 6 September Oates was summoned before the magistrate Sir Edmund Berry Godfrey to swear an oath prior to his testimony before the King. Oates claimed he had been at a Jesuit meeting held at the White Horse Tavern in the Strand, London on April 24, 1678. According to Oates, the purpose of that meeting was to discuss the assassination of Charles II. The meeting discussed a variety of methods which included: stabbing by Irish ruffians, shooting by two Jesuit soldiers, or poisoning by the Queen's physician, Sir George Wakeman.
Oates and Tonge were brought before the Privy Council later that month. The council interrogated Oates. On 28 September he made 43 allegations against various members of Catholic religious orders — including 541 Jesuits — and numerous Catholic nobles. He accused Sir George Wakeman, the Queen's physician, and Edward Colman, the secretary to Mary of Modena Duchess of York, of planning the assassination. Colman was found to have corresponded with a French Jesuit, which condemned him. Wakeman was later acquitted. Despite Oates' bad reputation, the Councillors were impressed by his confidence, his grasp of detail and his remarkable memory. A turning point came when he was shown five letters, supposedly written by well-known priests and giving details of the Plot, which he was suspected of forging: Oates "at a single glance" named each of the alleged authors. At this the Council were "amazed" and began to give much greater credence to the Plot; strangely it did not occur to them that Oates' ability to recognise the letters made it more likely that he had forged them.
Others Oates accused included Dr. William Fogarty, Archbishop Peter Talbot of Dublin, Samuel Pepys, and John Belasyse, 1st Baron Belasyse. The list grew to 81 accusations. Oates was given a squad of soldiers and he began to round up Jesuits.
Godfrey murder 
The allegations gained little credence until the murder of Sir Edmund Berry Godfrey, a member of Parliament and strong supporter of Protestantism. His disappearance on 12 October 1678, the finding of his mutilated body on 17 October, and the subsequent failure to solve his murder sent the Protestant population into an uproar. He had been strangled and run through with his own sword. Many of his supporters blamed the murder on Catholics. As Kenyon commented, "Next day, the 18th, James wrote to William of Orange that Godfrey's death was already 'laid against the Catholics', and even he, never the most realistic of men, feared that 'all these things happening together will cause a great flame in the Parliament.'" The Lords asked King Charles to banish all Catholics from a radius of 20 miles around London, which Charles granted on October 30th, 1678, but it was too late because London was already in a panic.
Oates seized on this murder as proof that the plot was true. The murder of Godfrey and the discovery of Edward Coleman's letters provided a solid basis of facts for the lies of Oates and the other informers who followed him. Oates was called to testify before the House of Lords and the House of Commons on October 23, 1678. He testified that he had seen a number of contracts signed by the Superior General of the Jesuits. The contracts appointed officers that would command an army of Catholic supporters to kill Charles II and establish a Catholic monarch. To this day, no one is certain who killed Sir Edmund Godfrey, and most historians regard the mystery as insoluble. Oates' associate William Bedloe denounced the silversmith Miles Prance, who in turn named three lay Catholics Berry, Green and Hill, who were tried, convicted and executed in February 1679; but it rapidly became clear that they were completely innocent, and that Prance, who had been subjected to torture, named them simply to buy his freedom.
The Plot before Parliament 
King Charles, aware of the unrest, returned to London and summoned Parliament. He remained unconvinced by Oates' accusations, but Parliament and public opinion forced him to order an investigation. Parliament truly believed that this plot was real, declaring, "This House is of opinion that there hath been and still is a damnable and hellish plot contrived and carried out by the popish recusants for assigning and murdering the King." Tonge was called to testify on October 25th, 1678 where he gave evidence on the Great Fire and, later, rumours of another similar plot. On November 1st, both Houses ordered an investigation in which a Frenchman, Choqueux, was discovered to be storing gunpowder in a house nearby. It was later uncovered that he was simply the King’s firework maker.
Trial of the Five Catholic Lords 
Oates became more daring and accused five Catholic lords (William Herbert, 1st Marquess of Powis, William Howard, 1st Viscount Stafford, Henry Arundell, 3rd Baron Arundell of Wardour, William Petre, 4th Baron Petre and John Belasyse, 1st Baron Belasyse) of involvement in the plot. The King reputedly dismissed the accusations, but Anthony Ashley Cooper, 1st Earl of Shaftesbury had the lords arrested and sent to the Tower on 25 October 1678. Seizing upon the anti-Catholic tide, Shaftesbury publicly demanded that the King's brother, James, be excluded from the royal succession, prompting the Exclusion crisis. On 5 November 1678, people burned effigies of the Pope instead of those of Guy Fawkes. At the end of the year, the parliament passed a bill, a second Test Act, excluding Catholics from membership of both Houses (a law not repealed until 1829).
On 1 November, 1678, the House of Commons resolved to proceed by impeachment against "the five popish lords". On 23 November all Arundell's papers were seized and examined by the Lords' committee; on 3 December the five peers were found guilty of high treason; and on 5 December the Commons announced the impeachment of Arundell. A month later Parliament was dissolved, and the proceedings were interrupted. In March 1679, it was resolved by both houses that the dissolution had not invalidated the motions for the impeachment. On 10 April 1679 Arundell and three of his companions (Belasyse was too ill to attend) were brought to the House of Lords to put in pleas against the articles of impeachment. Arundell complained of the uncertainty of the charges, and implored the peers to have them "reduced to competent certainty". But on 24 April this plea was voted irregular, and on 26 April the prisoners were again brought to the House of Lords and ordered to amend their pleas. Arundell replied by briefly declaring himself not guilty.
The trial was fixed for 13 May, but a quarrel between the two houses as to points of procedure, and the legality of admitting bishops to a capital trial, followed by a dissolution, delayed its commencement till 30 November 1680. On that day it was decided to proceed first against Lord Stafford, who was condemned to death on 7 December and beheaded on 29 December. His trial, compared to the other Plot trials, was reasonably fair, but as in all treason trials at that date the absence of defence counsel was a fatal handicap, and while Oates' credit had been seriously damaged, the principal prosecution witnesses, Turberville and Dugdale, struck even fair minded observers like John Evelyn as credible enough.
On 30 December, the evidence against Arundell and his three fellow-prisoners was ordered to be in readiness, but there public proceedings stopped. In fact the death of William Bedloe left the prosecution in serious difficulties, since one protection for a person accused of treason, that there must be two eyewitnesses to an overt act of treason, was observed scrupulously, and only Oates claimed to have evidence against the remaining Lords. Lord Petre died in the Tower in 1683. His companions remained there till 12 February 1684 when an appeal to the Court of King's Bench to release them on bail was successful. On 21 May 1685 Arundell, Powis, and Belasyse came to the House of Lords to present petitions for the annulling of the charges and on the following day the petitions were granted. On 1 June 1685 their liberty was formally assured on the ground that the witnesses against them had perjured themselves, and on 4 June the bill of attainder against Stafford was reversed.
Height of the hysteria 
On 24 November, 1678, Oates claimed the Queen was working with the King's physician to poison him and enlisted the aid of "Captain" William Bedloe, a notorious member of the London underworld. The King personally interrogated Oates, caught him out in a number of inaccuracies and lies, and ordered his arrest. However, a few days later, with the threat of constitutional crisis, Parliament forced the release of Oates.
Hysteria continued: Roger North wrote that it was as though "the very Cabinet of Hell has been opened". Noblewomen carried firearms if they had to venture outdoors at night. Houses were searched for hidden guns, mostly without any significant result. Some Catholic widows tried to ensure their safety by marrying Anglican widowers. The House of Commons was searched – without result – in the expectation of a second Gunpowder Plot.
Anyone even suspected of being Catholic was driven out of London and forbidden to be within ten miles of the city. William Staley, a young Catholic banker, made a drunken threat against the King and within 10 days was tried, convicted and executed for plotting to kill him. Oates, for his part, received a state apartment in Whitehall and an annual allowance. He soon presented new allegations, claiming assassins intended to shoot the King with silver bullets so the wound would not heal. The public invented their own stories, including a tale that the sound of digging had been heard near the House of Commons and rumours of a French invasion in the Isle of Purbeck. The evidence of Oates and Bedloe was supplemented by other informers; some like Thomas Dangerfield, were notorious criminals, but others like Stephen Dugdale, Robert Jenison and Edward Turberville, were respectable men who for whatever reason denounced innocent victims, and by their apparently plausible evidence made the Plot seem more credible. Dugdale in particular made such a good initial impression that even the King for the first time "began to think that there might be something in the Plot".
Waning of the hysteria 
However, public opinion began to turn against Oates; as Kenyon points out the steady protestations of innocence by all those who died took hold on the public mind. Further, outside London the priests who died were usually venerable and popular members of the community , and there was widespread horror at their executions. Even Lord Shaftesbury came to regret the mass executions, and is said to have quietly ordered the release of priests whose families he knew. Having had at least twenty-two innocent men executed, the last being Oliver Plunkett, the Catholic Archbishop of Armagh on 1 July 1681, the Chief Justice, William Scroggs began to declare people innocent and the King began to devise countermeasures. Tolerant in religion and generally inclined to clemency, Charles was embittered at the number of innocent men he had been forced to condemn; possibly thinking of the Act of Indemnity and Oblivion, he remarked that his people had never previously had cause to complain of his mercy. At the trial of Sir George Wakeman, and several priests tried with him, Scroggs virtually ordered the jury to acquit all of them, and despite public uproar the King made it clear that he approved of Scroggs' conduct. On 31 August 1681, Oates was told to leave his apartments in Whitehall, but remained undeterred and even denounced the King and the Duke of York. He was arrested for sedition, sentenced to a fine of £100,000 and thrown into prison.
When James II acceded to the throne in 1685 he had Oates retried for perjury. The death penalty was not available for perjury and Oates was sentenced to be stripped of clerical dress, whipped through London twice, and imprisoned for life and pilloried every year. Oates spent the next three years in prison. At the accession of William of Orange and Mary in 1689, he was pardoned and granted a pension of £260 a year but his reputation did not recover. The pension was suspended, but in 1698 was restored and increased to £300 a year. Oates died on 12 or 13 July 1705. Of the other informers, James II had pardoned Miles Prance for his perjury, but subjected Thomas Dangerfield to the same penalties as Oates; Dangerfield died in a scuffle with the barrister Robert Francis. Bedloe, Turbervile and Dugdale had died of natural causes while the Plot was still officially regarded as true.
Long-term effects 
The Society of Jesus suffered the most between 1678 and 1681. During this period, nine Jesuits were executed and twelve died in prison. Three other deaths were also attributable to the hysteria. They also lost Combe in Herefordshire, which was the Jesuit headquarters of South Wales. A quote from French Jesuit Claude de la Colombière highlights the plight of the Jesuits during this time period. He comments, "The name of the Jesuit is hated above all else, even by priests both secular and regular, and by the Catholic laity as well, because it is said that the Jesuits have caused this raging storm, which is likely to overthrow the whole Catholic religion."
Other Catholic religious orders such as the Carmelites, Franciscans, and the Benedictines were also affected by the hysteria. They were no longer permitted to have more than a certain number of members or missions within England. John Kenyon points out that European religious orders throughout the Continent were affected since many of them depended on the alms of the English Catholic community for their existence. Many Catholic priests were arrested and tried because the Privy Council wanted to make sure to catch all of those who might possess information about the supposed plot.
The hysteria had consequences for ordinary British Catholics. On October 30, 1687, a proclamation was made that required all Catholics who were not tradesmen or property owners to leave London and Westminster. They were not to enter a twelve-mile radius of the city without special permission. Throughout this period Catholics were subject to fines, harassment and imprisonment. It was not until the early 19th century that most of the anti-Catholic legislation was removed by the Roman Catholic Relief Act of 1829; anti-Catholic sentiment remained even longer among politicians and the general populace.
