House party
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.
