List of MPs elected to the English Parliament in 1660

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 Stuart Restoration was the reinstatement in May 1660 of the Stuart monarchy in England, Scotland, and Ireland. It replaced the Commonwealth of England, established in January 1649 after the execution of Charles I, with his son Charles II.

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. It began when Barebone's Parliament was dissolved, and the Instrument of Government appointed Oliver Cromwell as Lord Protector of the Commonwealth. Cromwell died in September 1658 and was succeeded by his son Richard Cromwell.

Sir Arthur Haselrig, 2nd Baronet was an English politician. A major critic of Charles I of England during the period of Personal Rule from 1629 to 1640, he was one of the Five Members whose attempted arrest sparked the First English Civil War in August 1642. As a leading Parliamentarian, he held various military and political posts during the Wars of the Three Kingdoms.

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.

The Convention Parliament was a parliament in English history which, owing to an abeyance of the Crown, assembled without formal summons by the Sovereign. Sir William Blackstone applied the term to only two English Parliaments, those of 1660 and 1689, but some sources have also applied the name to the parliament of 1399.

The Wars of the Three Kingdoms were a series of conflicts fought between 1639 and 1653 in the kingdoms of England, Scotland and Ireland, then separate entities in a personal union under Charles I. They include the 1639 to 1640 Bishops' Wars, the First and Second English Civil Wars, the Irish Confederate Wars, the Cromwellian conquest of Ireland and the Anglo-Scottish War of 1650–1652. They resulted in the execution of Charles I, the abolition of monarchy, and founding of the Commonwealth of England, a unitary state which controlled the British Isles until the Stuart Restoration in 1660.

The English Council of State, later also known as the Protector's Privy Council, was first appointed by the Rump Parliament on 14 February 1649 after the execution of King Charles I.

The Third Protectorate Parliament sat for one session, from 27 January 1659 until 22 April 1659, with Chaloner Chute and Thomas Bampfylde as the Speakers of the House of Commons. It was a bicameral Parliament, with an Upper House having a power of veto over the Commons.

The Convention Parliament of England followed the Long Parliament that had finally voted for its own dissolution on 16 March that year. Elected as a "free parliament", i.e. with no oath of allegiance to the Commonwealth or to the monarchy, it was predominantly Royalist in its membership. It assembled for the first time on 25 April 1660.
