Scots proclaim Charles II as king

Cromwell left Ireland in May 1650 and several months later invaded Scotland after the Scots had proclaimed Charles I's son Charles II as King. Cromwell was much less hostile to Scottish Presbyterians, some of whom had been his allies in the First English Civil War, than he was to Irish Catholics. He described the Scots as a people "fearing His name, though deceived". He made a famous appeal to the General Assembly of the Church of Scotland, urging them to see the error of the royal alliance—"I beseech you, in the bowels of Christ, think it possible you may be mistaken." The Scots' reply was robust: "would you have us to be sceptics in our religion?" This decision to negotiate with Charles II led Cromwell to believe that war was necessary.
