Pride’s Purge is the name commonly used for an event that took place on 6 December 1648, when soldiers prevented MPs considered hostile to the New Model Army from entering the House of Commons.
Despite defeat in the First English Civil War, Charles I retained significant political power. This allowed him to create an alliance with Scots Covenanters and Parliamentarian moderates to restore him to the English throne. The result was the 1648 Second English Civil War, in which he was defeated once again.
Convinced only his removal could end the conflict, senior commanders of the New Model Army took control of London on 5 December. Next day, soldiers commanded by Colonel Thomas Pride forcibly excluded from the Long Parliament those MPs viewed as their opponents, and arrested 45.
The Purge cleared the way for the execution of Charles in January 1649, and establishment of the Protectorate; it is considered the only recorded military coup d’état in English history.
When the First English Civil War began in 1642, the vast majority on both sides believed a ‘well-ordered’ monarchy was divinely mandated. They disagreed on what ‘well-ordered’ meant, and who held ultimate authority in clerical affairs. Royalists generally supported a Church of England governed by bishops, appointed by, and answerable to, the king; Puritans believed he was answerable to the leaders of the church, appointed by their congregations.
However, ‘Puritan’ was a term for anyone who wanted to reform, or ‘purify’, the Church of England, and contained many different perspectives. Presbyterians were the most prominent in the Long Parliament; in general, they wanted to convert the Church of England into a Presbyterian body, similar to the Church of Scotland. Independents opposed any state church, and although smaller in number, included Oliver Cromwell, as well as much of the New Model Army.
Having established control of Scotland in the 1639 to 1640 Bishops Wars, the Covenanters viewed the 1643 Solemn League and Covenant with Parliament as a way to preserve it, by preventing Royalist victory in England. As the war progressed, they and their English co-religionists came to see the Independents, and their political allies like the Levellers, as a greater threat to the established order than the Royalists.
In 1646, many Parliamentarians assumed military defeat would force Charles I to agree terms, but this was a fundamental misunderstanding of his character. Charles refused to agree any substantial concessions, frustrating allies and opponents alike. His negotiations with the Scots and English Presbyterians led to the 1648 Second English Civil War, which was quickly suppressed. However, it created a political grouping led by Cromwell, who believed only his removal could end the conflict, and the ability to enforce it in the New Model Army.
Despite defeat in the Second Civil War, Parliament continued negotiations with Charles, but by the beginning of November, the Army had lost patience. On 10 November, Henry Ireton presented the draft Remonstrance to the Army General Council, setting out a state without Charles, including an elective monarch. While the Council was initially divided on whether to approve it, they did so on 15th when it seemed Parliament was about to restore Charles unconditionally. The Army’s conviction he could not be trusted increased after intercepting messages he sent to an advisor, stating any concessions were made only to facilitate his escape.
On 1 December, Fairfax ordered Charles be taken from his Parliamentary guards on the Isle of Wight, and moved to Hurst Castle on the mainland. The next day, the New Model occupied key positions in London, to prevent interference from Presbyterian elements of the London Trained Bands; Fairfax established his headquarters in Whitehall, near the Houses of Parliament.
After an all-day meeting on 5 December, Parliament voted by 129 to 83 to continue negotiating with the king. Next morning, acting under orders from Ireton, a detachment under Colonel Thomas Pride and Sir Hardress Waller ordered the Trained Bands who normally guarded the House to withdraw. They then took up position on the stairs leading into the chamber, supported by cavalry from Nathaniel Rich’s Regiment of Horse.
As the MPs arrived, Pride checked their names against a list of those considered enemies of the Army, assisted by Lord Grey of Groby, who helped identify them. The list contained names of 180 of the 470 eligible members, including all 129 who had voted to continue negotiations the day before. Some prominent opponents, such as Denzil Holles, fled the city.
A total of 140 MPs were refused entry by Pride, 45 of whom were arrested, and held in two inns in the Strand. Many later complained of rough treatment from their New Model guards, who blamed them for their arrears of pay. Most were released in late December, but former Parliamentarian generals William Waller, and Richard Browne were held for nearly three years.
This left around 156 members present in London, with another 40 or so absent elsewhere, which became known as the Rump Parliament. While assumed to be supportive of the Army, this was not necessarily the case; many were horrified by Pride’s actions, and more than 80 of those who remained in London refused to attend. The vote to end negotiations with Charles was taken by only 83 MPs.
Between December 1648 to January 1649, Pride’s regiment received nearly £8,000 in back pay, substantially more than any other unit in this period. He was later appointed to the tribunal that tried Charles for treason, and signed his death warrant; he became wealthy under the Protectorate, and died in 1659.
The Purge eliminated from Parliament those who backed a negotiated settlement with Charles, which included moderate Independents, as well as Presbyterians. However, even those who agreed he had to be removed did not necessarily support his execution; this included Fairfax, who refused to take part in his trial, and initially Cromwell, who returned to London from the siege of Pontefract Castle in early December. In return for sparing his life, he hoped Charles would order the Duke of Ormond to end negotiations with the Irish Confederacy, and prevent a new war in Ireland.
Once it became clear Charles had no intention of doing so, Cromwell became convinced he had to die, stating ‘we will cut off his head with the crown still on it.’ On 1 January 1649, the Commons passed an Ordinance to try the king for treason; when this was rejected by the House of Lords, they declared themselves the supreme power in the state, and proceeded with the trial. 
The trial was backed by Republicans like Edmund Ludlow, who argued Charles must die to ‘appease the wrath of God for the blood shed during the wars’, and supported the Purge as the only way to ensure this. However, they were outnumbered by those who opposed it; only 52 of the 135 appointed judges turned up. A demand by Charles he be tried by Parliament was blocked by Ireton and Cromwell, as even the Rump was likely to vote against the death sentence.
Charles was executed on 30 January, but in a society that placed enormous emphasis on legality’s role in the rule of law, the circumstances of his death, and the military coup that proceeded it, tainted the Protectorate from its inception. Intended to remove the Army’s opponents from Parliament, the Purge only deepened internal divisions, which continued until it was dissolved in 1653.
