The countries that now make up the United Kingdom, together with the Republic of Ireland, were briefly ruled as a republic in the 17th century, first under the Commonwealth consisting of the Rump Parliament and the Council of State (1649–1653) and then under the Protectorate of Oliver Cromwell and later his son Richard (1653–1659), and finally under the restored Rump Parliament (1659–1660). The Commonwealth Parliament represented itself as a republic in the classical model, with John Milton writing an early defence of republicanism in the idiom of constitutional limits on a monarch's power. Cromwell's Protectorate was less ideologically republican and was seen by Cromwell as restoring the mixed constitution of monarchy, aristocracy and democracy found in classical literature and English common law discourse.
