On 4 July a Nominated Assembly, nicknamed the "Assembly of Saints" or Barebone's Parliament (named after one of its members), took on the role of more traditional English Parliaments. Within a month of the Rump's dismissal, Oliver Cromwell on the advice of Thomas Harrison and with the support of other officers in the Army, sent a request to Congregational churches in every county to nominate those they considered fit to take part in the new government. On 20 April 1653, after learning that Parliament was attempting to stay in session despite an agreement to dissolve, and having failed to come up with a working constitution, Cromwell, with the backing of the Grandees in the Army Council, marched soldiers into the debating chamber and forcibly ended the Rump's session. On 28 October 1651 the English Rump Parliament passed a declaration for union of the English and Scottish parliaments, but the process was not completed until an Act of Union was passed on 26 June 1657 (See Tender of Union). The process of placing the governance of Scotland on a more long term constitutional footing began shortly after the defeat of the Scottish Royalists and Charles II at the Battle of Worcester. Scotland was invaded, subjugated and placed under an English military governor first appointed in 1651. All of Ireland came under the same governance (after the successful Cromwellian conquest of Ireland) with the appointment of a Parliamentary military governor in Dublin. The Act declaring England to be a Commonwealth, which established England, together with " all the Dominions and Territoryes thereunto belonging", as a republic, had been passed on, following the trial and execution of Charles I in January of that year. Since 1649 and prior to the Protectorate, England, Ireland and later Scotland had been governed as a republic by the Council of State and the Rump Parliament.
