The Puritan Revolution escaped the control of its creators. The parliamentarians who went to war with Charles I in 1642 did not want or expect the fundamental changes that would follow seven years later: the trial and execution of the king, the abolition of the House of Lords, and the creationof the only republic in English history. There were startling and unexpected developments, too, in religion and ideas: the spread of unorthodox doctrines; the attainment of a wide measure of liberty of conscience; and new thinking about the moral and intellectual bases of politics and society. God'sInstruments centres on the principal instrument of radical change, Oliver Cromwell, and on the unfamiliar landscape of the decade he dominated, from the abolition of the monarchy in 1649 to the return of the Stuart dynasty in 1660.Its theme is the relationship between the beliefs or convictions of politicians and their decisions and actions. Blair Worden explores the biblical dimension of Puritan politics; the ways that a belief in the workings of divine providence affected political conduct; Cromwell's commitment to libertyof conscience and his search for godly reformation through educational reform; the constitutional premises of his rule and those of his opponents in the struggle for supremacy between parliamentary and military rule; and the relationship between conceptions of civil and religious liberty. Theconflicts Worden reconstructs are placed in the perspective of long-term developments, of which many historians have lost sight. The final chapters turn to the guiding convictions of two writers at the heart of politics, John Milton and the royalist Edward Hyde, Earl of Clarendon. Material frompreviously published essays, much of it expanded and extensively revised, comes together with newly written chapters to bring fresh evidence and argument to a period of lively debate and interest.
