Instrument of Government (1653)

Definition

The Instrument of Government was the written constitutional framework that established the English Protectorate around a Lord Protector, Council of State, and Parliament after the failure of Barebone’s Parliament.

Current Synthesis

Associated especially with John Lambert, the Instrument attempted to convert improvised rule after regicide into a durable institutional arrangement. It replaced the old king, Lords, and Commons formula and installed Oliver Cromwell as Lord Protector.

The episode’s significance claim is deliberately qualified. A written constitution could specify offices without settling the regime’s social mandate, civilian control, relationship to monarchy, or succession. By Cromwell’s death, hereditary and elective versions of kingship and protectorship remained live possibilities, and Richard Cromwell’s fall showed that personal military authority had not become secure constitutional authority.

Key Claims

• The Instrument formalized the Protectorate after earlier parliamentary experiments failed.
• It replaced the traditional tripartite constitution with Protector, council, and Parliament.
• Written institutional design did not eliminate the army’s independent political power.
• Protectoral office remained close enough to monarchy to create unresolved quasi-monarchical succession choices.
• Richard Cromwell’s failure exposed the gap between constitutional text and transferable authority.

Evidence

Design and adoption

• 54. Cromwell and the Protectorate identifies Lambert with the Instrument’s production and Cromwell’s acceptance of the protectorship.

Institutional structure

• 54. Cromwell and the Protectorate contrasts Protector, Council of State, and Parliament with king, Lords, and Commons.

Succession limits

• 54. Cromwell and the Protectorate traces unresolved hereditary and elective choices and the collapse after Richard Cromwell lacked army support.

Counterevidence & Qualifications

The episode calls the Instrument the world’s first written constitution, but that ranking depends on definitions of constitution, state, codification, and continuity and is retained as source-attributed rather than settled. The source does not provide a clause-by-clause account or establish Lambert as sole author. Failure of succession does not mean the text had no institutional effect.

What Changed

• Created a synthesis distinguishing written constitutional design from settled legitimacy and transferable coercive authority.
