The Exclusion Bill Parliament was a Parliament of England during the reign of Charles II of England, named after the long saga of the Exclusion Bill. Summoned on 24 July 1679, but prorogued by the king so that it did not assemble until 21 October 1680, it was dissolved three months later on 18 January 1680/81.
Succeeding the long Cavalier Parliament and the short-lived Habeas Corpus Parliament of March to July 1679, this was the third parliament of the King's reign. Its character was much influenced by the aftermath of the Popish Plot crisis.
On 15 May 1679, the supporters of Anthony Ashley Cooper, 1st Earl of Shaftesbury, had introduced the Exclusion Bill into the Commons with the aim of excluding the king's brother, James, Duke of York, from the succession to the throne. A fringe group began to support the claim of Charles's illegitimate son, the Duke of Monmouth. As it seemed likely that the bill would pass, Charles exercised his Royal prerogative to dissolve Parliament.
A new parliament was summoned on 24 July 1679, and elections to the new House of Commons were held on various dates in the weeks which followed, but in general they went badly for the court party. With parliament expected to meet in October 1679, King Charles prorogued the parliament until 26 January 1680. Shaftesbury was anxious that the king might be intending not to meet this new parliament, so he launched a petitioning campaign to pressure the king to do so. He also wrote to the Duke of Monmouth, advising him to return from exile, and on 27 November 1679 Monmouth entered London amid scenes of widespread celebration. On 7 December 1679, a petition signed by Shaftesbury and fifteen other Whig peers called on Charles to meet parliament, and this was followed on 13 January 1679/80 by a similar petition of 20,000 signatures. However, instead of meeting parliament Charles further prorogued it and recalled his brother the Duke of York from Scotland. With this, Shaftesbury urged his friends on the Privy Council to resign, and four did so.
