For the first four years after the death of King Charles I, the country was governed by the House of Commons. Then in 1653 the army gave power to Oliver Cromwell with the title of Lord Protector. The years 1653–9 are therefore known as the Protectorate . The Commonwealth ended with the Restoration of King Charles II. 联邦： 英国历史上一段时期（1649–60），该国在没有国王或王后的情况下进行统治。国王查理一世去世后的头四年，该国由下议院统治。然后在1653年，军队以保卫勋爵的头衔授予奥利弗·克伦威尔（Oliver Cromwell）权力。因此1653–9年被称为保护国。英联邦以查理二世国王的复辟而告终。
