The Council of State was set up by Parliamentary ordinance on 13 February 1649 as a successor to the Derby House Committee which had taken over much of the Privy Council's executive role in the State. It was annually renewed by Parliament and insisted on choosing its own President. From May 1649 it was housed at Whitehall. Membership was reduced from 41 to 15 in 1653 when it became the Protector's Council. By 1656 it was being styled the Privy Council. After Richard Cromwell's abdication in 1659 the Council of State was revived and remodelled twice before it relapsed into a Privy Council. It spawned committees, both standing and ad hoc; the former included the Admiralty Committee, set up in 1649.
