English interregnum

The Interregnum was the period between the execution of Charles I on 30 January 1649 and the arrival of his son Charles II in London on 29 May 1660 which marked the start of the Restoration. During the Interregnum England was under various forms of republican government (see Commonwealth of England; this article describes other facets of the Interregnum).

The politics of the period were dominated by the wishes of the Grandees (Senior Officers) of the New Model Army and their civilian supporters. They encouraged (or at least tolerated) several republican regimes.

From 1649 until 1653 executive powers lay with Council of State, while legislative functions were carried out by the Rump Parliament.

In 1653 the Grandees, with Oliver Cromwell in the lead, dismissed the Rump, and replaced it with a Nominated Assembly (nicknamed the Parliament of Saints and Barebone's Parliament) made up of 140 nominees, 129 from England, five from Scotland and six from Ireland. It proved to be as difficult for the executive to work with this parliament as it had with the Rump, so, after sitting for five months, members friendly to the Grandees engendered its dissolution on 12 December 1653.

The Instrument of Government was adopted on 15 December 1653 and the pre-eminent Grandee Oliver Cromwell was installed as Lord Protector on the following day. The Instrument of Government granted executive power to the Lord Protector. Although this post was elective, not hereditary, it was to be held for life. It also required the calling of triennial Parliaments, with each sitting for at least five months.
