an English Parliamentary general and politician. He fought during the English Civil War and then in Oliver Cromwell's Scottish campaign (1650–51), becoming thereafter active in civilian politics until his dismissal by Cromwell in 1657. During this time he wrote the Instrument of Government, Britain's only codified constitution, and was influential in bringing about the Protectorate. He remained inactive from politics until after the resignation of Richard Cromwell, when he was re-appointed to a position in the army in 1659.
