The decade was one of the most momentous in English history: it saw a religious break with the Pope, unprecedented use of parliament, the dissolution of all monasteries, and the coming of the Protestantism which decisively shaped the future of this country. Cromwell was central to all this, but establishing his role with precision, at a distance of nearly 500 years and after the destruction of many of his papers at his own fall, has been notoriously difficult. Diarmaid MacCulloch's biography draws together national and international events, and reveals the channels through which so much of power in early Tudor England flowed. It overturns many received interpretations, for example that Cromwell and Anne Boleyn were allies because of their common religious sympathies, showing how he in fact destroyed her; or that Cromwell was a cynical, 'secular' politician without deep-felt religious commitment. It introduces the many different personalities contributing to these foundational years, all worrying about what MacCulloch calls the 'terrifyingly unpredictable' Henry VIII, and shows how things could easily have turned out differently. MacCulloch's biography for the first time reveals his true place in the making of modern England and Ireland, for good and ill.
