Charles II lands at Dover at the invitation of the Convention Parliament, which marks the end of the Cromwell-proclaimed Commonwealth of England, Scotland and Ireland and begins the Restoration of the British monarchy.

Charles II was King of Scotland from 1649 until 1651 and King of England, Scotland, and Ireland from the 1660 Restoration of the monarchy until his death in 1685.

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.

Oliver Cromwell was an English statesman, politician and soldier, widely regarded as one of the most important figures in British history. He came to prominence during the Wars of the Three Kingdoms, initially as a senior commander in the Parliamentarian army and latterly as a politician. A leading advocate of the execution of Charles I in January 1649, which led to the establishment of the Commonwealth of England, Cromwell ruled as Lord Protector from December 1653 until his death.

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.
