British Interregnum in the context of "Restoration (1660)"

British republicans seek to replace the United Kingdom's monarchy with a republic led by an elected head of state. Monarchy has been the form of government used in the United Kingdom and its predecessor domains almost exclusively since the Middle Ages, except for a brief interruption from 1649–1660, during which a nominally republican government did exist under the leadership of Oliver Cromwell.

After Cromwell's Protectorate fell and the monarchy was restored, governing duties were increasingly handed to Parliament, especially as a result of the Glorious Revolution of 1688. The adoption of the constitutional monarchy system made the argument for full republicanism less urgent. It was once again a topic of discussion during the late 18th century with the American Revolution, and grew more important with the French Revolution, when the concern was how to deal with the French Republic on their doorstep. This led to a widespread anti-republican movement in Britain, and the issue was dormant for a time.
