English Civil War: The English Civil War (1642–1651) was a series of armed conflicts and political machinations between Parliamentarians ("Roundheads") and Royalists ("Cavaliers") over, principally, the manner of England's government.  The first (1642–1646) and second (1648–1649) wars pitted the supporters of King Charles I against the supporters of the Long Parliament, while the third (1649–1651) saw fighting between supporters of King Charles II and supporters of the Rump Parliament.  The war ended with the Parliamentarian victory at the Battle of Worcester on 3 September 1651.

Charles II of England: Charles II (29 May 1630 – 6 February 1685) was king of England, Scotland and Ireland.  He was king of Scotland from 1649 until his deposition in 1651, and king of England, Scotland and Ireland from the restoration of the monarchy in 1660 until his death.

William Clarke (English politician): Sir William Clarke (died 1666) was an English politician.  Born about 1623 in London of obscure parentage, he was admitted as a student to Inner Temple in 1645 and called to the bar in 1653.  On 28 Jan. 1661 he was appointed Secretary at War, after having served for at least the previous twelve years as secretary to General Monck.  Clarke served as Secretary to the Council of the Army, 1647–1649, and Secretary to General Monck and the Commanders of the Army in Scotland, 1651-1660.  Clarke served as the Secretary at War from 1661 to his death in 1666, as a casualty of war with the Dutch.  With the Restoration, both Monck and Clarke had great favour with Charles II, who bestowed knighthood upon Clarke and gave him the use, for a term of some years, of the great lodge and 60 acres within Marylebone Park.  His widow was Dorothy Clarke, and they had one son, George Clarke.

Interregnum (1649–1660): The "interregnum" in England, Scotland, and Ireland started with the execution of Charles I in January 1649 (September 1651 in Scotland) and ended in May 1660 when his son Charles II was restored to the thrones of the three realms, although he had been already acclaimed king in Scotland since 1650.

John Cockburn (Scottish officer): Colonel John Cockburn was an officer in the Scottish Covenanter army in the late 1640s and early 1650s during the Wars of the Three Kingdoms.  In this capacity he led Lowland soldiers against Montrose's Scottish Royalist forces during the First English Civil War (1642-1646), when the Covenanter parliament of Scotland was allied with the English Parliamentarians against King Charles I.  Colonel Cockburn led the colorfully defiant but futile Scottish resistance at Hume Castle during the Third English Civil War (1649-1651), when a Parliamentary army led by Oliver Cromwell invaded Scotland after its Covenenter government had made an uneasy alliance with King Charles II.
