Republicanism in the United Kingdom

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, with the exception of the Interregnum from 1649–1660, during which a nominally republican government did exist under the rule of Oliver and later Richard Cromwell.
