The Dramatic Rise & Fall of Thomas Cromwell Thomas Cromwell, chief architect of the English Reformation, served as principal minister of Henry VIII from 1532 to 1540, the most tumultuous period in Henry's thirty-seven year reign. Many of the momentous events of the 1530s are attributed to Cromwell's agency: the Reformation, the dissolution of the monasteries and the fall of Henry's second wife, the bewitching Anne Boleyn. Cromwell has been the subject of close and continuous attention for the last half-century, with generally positive appraisal of his work and achievements by historians. This new biography shows the true face of a Machiavellian Tudor statesman without equal.
