When Oliver Cromwell died in September 1658, Monck transferred his support to his son
Richard, who was appointed
Lord Protector. The
Third Protectorate Parliament elected in January 1659 was dominated by moderate Presbyterians like Monck and Royalist sympathisers, whose main objective was to reduce the power and expense of the military. In April, army radicals led by
John Lambert and
Charles Fleetwood dissolved Parliament and forced the resignation of Richard Cromwell. Sometimes known as the
Wallingford House party, the new regime abolished the Protectorate, reseated the
Rump Parliament dismissed by Cromwell in 1653 and began removing officers and officials of suspect loyalty, including many of those serving in Scotland. Monck was left in place largely because rumours of another Royalist rising made it preferable to retain him. Both his cousin
John Grenville and brother Nicholas were connected with the
Royalist underground and in July 1659, Nicholas brought him a personal appeal from
Charles II, asking for his help and offering up to £100,000 per year for his assistance. When
Booth's Uprising broke out in August 1659, Monck considered joining it but the revolt collapsed before he had time to commit himself. In October, the Wallingford House group dismissed the Rump before being forced to reinstate it in early December. By the end of 1659, England appeared to be drifting into anarchy, with widespread demands for new elections and an end to military rule. Monck declared his support for the Rump against the Republican faction led by Lambert, while co-ordinating with Sir
Theophilus Jones, a former colleague in Ireland who seized
Dublin Castle in late December. At the same time, he marched his army to the English border, supported by a force raised by former
New Model Army commander Sir
Thomas Fairfax. Outnumbered and unpaid, Lambert's troops melted away; on 2 February Monck entered London and in April elections were held for a
Convention Parliament. While his backing was essential to the
Stuart Restoration, modern historians question whether the policy was initiated by Monck as opposed to following majority opinion, which by now was overwhelmingly in favour of reinstating the monarchy. Although he was elected MP for Devon, observers noted that he had little interest in politics, while his lack of a regional power base in England and the proposed reduction of the army worked against his future influence. It has also been suggested the Royalist sympathies of his wife played an important role in his decision. Regardless of his motives, the
Declaration of Breda issued by Charles on 4 April 1660 was largely based on Monck's recommendations. It promised a general pardon for actions committed during the
civil wars and
Interregnum, with the exception of the
regicides, retention by the current owners of property purchased during the same period, religious toleration and payment of arrears to the army. Based on these terms, Parliament resolved to proclaim Charles king and invited him to return to England; he left Holland on 24 May and entered London five days later. ==Later career and death==
