The Commonwealth of England was the political structure during the period from 1649 to 1660 when England and Wales, later along with Ireland and Scotland, were governed as a republic after the end of the Second English Civil War and the trial and execution of Charles I. The republic's existence was declared through "An Act declaring England to be a Commonwealth", adopted by the Rump Parliament on 19 May 1649. Power in the early Commonwealth was vested primarily in the Parliament and a Council of State. During the period, fighting continued, particularly in Ireland and Scotland, between the parliamentary forces and those opposed to them, in the Cromwellian conquest of Ireland and the Anglo-Scottish war of 1650–1652.
The Long Parliament was an English Parliament which lasted from 1640 until 1660. It followed the fiasco of the Short Parliament, which had convened for only three weeks during the spring of 1640 after an 11-year parliamentary absence. In September 1640, King Charles I issued writs summoning a parliament to convene on 3 November 1640. He intended it to pass financial bills, a step made necessary by the costs of the Bishops' Wars against Scotland. The Long Parliament received its name from the fact that, by Act of Parliament, it stipulated it could be dissolved only with agreement of the members; and those members did not agree to its dissolution until 16 March 1660, after the English Civil War and near the close of the Interregnum.
The Protectorate, officially the Commonwealth of England, Scotland and Ireland, was the English form of government lasting from 16 December 1653 to 25 May 1659, under which the kingdoms of England, Scotland, and Ireland, with their associated territories were joined together in the Commonwealth of England, governed by a Lord Protector.

Cromwell died in September 1658 and was succeeded by his son Richard Cromwell.
The Rump Parliament was the English Parliament after Colonel Thomas Pride had commanded his soldiers, on 6 December 1648, to purge the Long Parliament of members against the Grandees' intention to try King Charles I for high treason.

It also said that no action was to be taken against those involved at any later time, and that the Interregnum was to be legally forgotten.

It was led by William Cunningham, 9th Earl of Glencairn (1610–1664), who was given command of the Royalist forces in Scotland by Charles II. Initially successful it began to suffer divisions when John Middleton arrived to replace Glencairn as commander, resulting in a series of duels between officers. It was defeated when Thomas Morgan caught Middleton's army at Dalnaspidal on 19 July 1654. Although the rising was unsuccessful it forced a change of policy by the Cromwellian regime, which now looked for a reconciliation with former Royalists and Engagers.
