12. =The Protectorate, and the Instrument of Government. 1653.=--On December 16 a constitutional document, known as _The Instrument of Government_, was drawn up by Cromwell's military supporters, and accepted by himself. Cromwell was to be styled Lord Protector, a title equivalent to that of Regent, of which the last instance had been that of the Protector Somerset (see p. 412). The Protector was to enter, to some extent, upon the duties which had formerly devolved on the king. There was to be a Parliament consisting of a single House, which was to meet once in three years, from which all who had taken the king's part were excluded, as they also were from voting at elections. The constituencies were to be almost identical with the reformed ones established by Vane's Reform Bill (see p. 566). The Protector was to appoint the executive officials, and to have a fixed revenue sufficient to pay the army and navy and the ordinary expenses of Government; but if he wanted more for extraordinary purposes he could only obtain it by means of a Parliamentary grant. New laws were to be made by Parliament alone, the Protector having no veto upon them, though he was to have an opportunity of criticising them, if he wished to urge Parliament to change its purpose. The main lines of the constitution were, however, laid down in the Instrument itself, and Parliament had no power given it to make laws contrary to the Instrument. In the executive government the Protector was restrained, not by Parliament, but by a Council of State, the members of which he could not dismiss as the king had dismissed his Privy Councillors. The first members were nominated in the Instrument, and were appointed for life; but when vacancies occurred, Parliament was to give in six names, of which the Council was to select two, leaving to the Protector only the final choice of one out of two. Without the consent of this entirely independent Council, the Protector could take no step of importance.
