English Absolutism under James I and Charles I led to tensions with Parliament over taxation and religious policies. Charles I dissolved Parliament and attempted to rule without it, angering them. This resulted in the English Civil War between the Royalist Cavaliers and the Parliamentarian Roundheads led by Oliver Cromwell. Cromwell defeated the Cavaliers and had Charles I executed. England then became a republic under the Puritan-led Commonwealth before the monarchy was restored with Charles II, though it was now limited by the Petition of Right and Bill of Rights.
