United Kingdom

The army’s intervention transformed civil war into revolution. Parliament, which in 1646 had argued that it was the fundamental authority in the country, by 1647 was but a pawn in a new game of power politics. The perceived corruption of Parliament made it, like the king, a target of reform. Initiative was now in the hands of the king and the army, and Charles I tried to entice Cromwell and Henry Ireton, the army’s leading strategist, to bargain his restoration for a tolerant church settlement. But the officers were only one part of a politicized army that was bombarded with plans for reorganizing the state. Among the most potent plans were those of the Levelers, led by John Lilburne, who desired that a new compact between ruler and ruled, the Agreement of the People (1647), be made. This was debated by the council of the army at Putney in October. The Levelers’ proposals, which had much in common with the army’s, called for the reform of Parliament through elections based upon a broad franchise and for a generally tolerant church settlement. Turmoil in the army led Fairfax and Cromwell to reassert military discipline, while the machinations of Charles led to the second Civil War (1648).

Charles had now managed to join his English supporters with discontented Scots who opposed the army’s intervention in politics. Though the fighting was brief, it was bloody. Fairfax stormed Colchester (1648) and executed the ringleaders of the English rebellion, and Cromwell and several New Model regiments defeated the invading Scots at the Battle of Preston (1648).

The second Civil War hardened attitudes in the army. The king was directly blamed for the unnecessary loss of life, and for the first time alternatives to Charles Stuart, “that man of blood,” were openly contemplated. Parliament too was appalled by the renewal of fighting. Moderate members believed that there was still a chance to bring the king to terms, despite the fact that he had rejected treaty after treaty. While the army made plans to put the king on trial, Parliament summoned its strength for one last negotiation, the abortive Treaty of Newport. Even now the king remained intransigent, especially over the issue of episcopacy. New negotiations infuriated the army, because it believed that Parliament would sell out its sacrifices and compromise its ideals. On December 6, 1648, army troops, under the direction of Col. Thomas Pride, purged the House of Commons. Forty-five members were arrested, and 186 were kept away. A rump of about 75 active members were left to do the army’s bidding. They were to establish a High Court of Justice, prepare a charge of treason against the king, and place him on trial in the name of the people of England. Pride’s Purge was a last-minute compromise made to prevent absolute military rule. With Cromwell deliberately absent in the north, Ireton was left to stave off the argument, made by the Levelers, that Parliament was hopelessly corrupt and should be dissolved. The decision to proceed by trial in the High Court of Parliament was a decision in favour of constitutional forms, however much a shadow they had become.

The king’s trial took place at the end of January. The Court of Justice was composed of members of Parliament, civilians, and army officers. There was little enthusiasm for the work that had to be done. No more senior judge than John Bradshaw could be found to preside, and he wore a hat ringed with iron in fear of assassination. The charges against the king, however politically correct, had little legal basis, and Charles deftly exposed their weakness, but, like Strafford before him, Charles was to be sacrificed to the law of necessity if not the law of England. On January 30, 1649, at the wall of his own palace, Charles I was beheaded. A witness recorded in his diary, “Such a groan went up as I had never before heard.”

The execution of the king aroused hostility not only in England but also throughout Europe. Regicide was considered the worst of all crimes, and not even the brilliance of John Milton in The Tenure of Kings and Magistrates (1649) could persuade either Catholic or Protestant powers that the execution of Charles I was just. Open season was declared against English shipping, and Charles II was encouraged to reclaim his father’s three kingdoms.
