Pride's Purge is the name commonly given to an event that took place on 6 December 1648, when soldiers prevented
members of Parliament considered hostile to the
New Model Army from entering the
House of Commons of England
The House of Commons of England was the lower house of the Parliament of England (which Laws in Wales Acts 1535 and 1542, incorporated Wales) from its development in the 14th century to the union of England and Scotland in 1707, when it was re ...

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

Background

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

"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

along with a significant portion of the
New Model Army.
Having won control of Scotland in the 1639 to 1640
Bishops' Wars, the
Covenanters viewed the 1643
Solemn League and Covenant as a way to preserve their dominance by preventing a Royalist victory in England. Moderate
Parliamentarians like
Denzil Holles wanted to re-establish what they considered to be a long-standing English legal principle that the king ruled with the consent of

as a greater threat to the established order than the Royalists.
In 1646, most Parliamentarians assumed military defeat would force
Charles I to comply with their terms, but his refusal to make any substantial concessions frustrated allies and opponents alike. He successfully exploited divisions among his opponents to negotiate an alliance with Scots and English Presbyterians which led to the 1648
Second English Civil War. Although quickly suppressed, it created a political grouping within the New Model Army who believed Charles had proved he could not be trusted and only his removal could end the conflict. For the vast majority, including Cromwell, at this stage, it meant
Abdication rather than execution.
Parliament
continued negotiations with Charles but by the beginning of November, the Army had lost its patience. On 10 November,
Henry Ireton presented the draft Remonstrance to the Army General Council, which set out a constitutional vision of a state with Charles replaced by an elected monarch. While the Council was initially divided on whether to approve it, they did so on the 15th when it seemed Parliament was about to restore Charles unconditionally. They decided to act after intercepting secret messages from Charles stating any concessions he made were intended only to facilitate his escape.
Pride's Purge
On 1 December, Fairfax ordered Charles be taken from his Parliamentary guards on the
Isle of Wight

Hurst Castle on the mainland. The next day, the New Model Army occupied key positions in London, to prevent interference from Presbyterian elements of the London
Trained Bands; Fairfax established his headquarters in

, 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 colonel
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 the names of 180 of the 470 eligible members, including all 129 who the day before had voted to continue negotiations with the King. 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.
Aftermath
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

, 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. Even those who wanted him 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

, the Commons 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. They were outnumbered by those who opposed it; only 52 of the 135 appointed judges turned up. A demand by Charles that he be tried by Parliament was blocked by Ireton and Cromwell, as even the Rump Parliament was likely to vote against the death sentence.
Charles was executed on 30 January, but in a society that placed enormous emphasis on the

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.
