Despite the very considerable scholarly attention focused on Thomas Cromwell in recent decades, surprisingly little is known or written about his private financial affairs and, in particular, about the acquisition and management of his landed estates. His principal but badly outdated biographer, R. B. Merriman, was content with a few sweeping generalizations about immense ill-gotten wealth; the only modern biography devotes to this topic barely two paragraphs; and G. R. Elton, who began and sustains the Cromwellian renaissance, is concerned primarily with the public man.
Yet at the time of his arrest in 1540, Cromwell was one of the biggest landowners in the southeastern home counties, the end result of an active decade of buying and selling lands, augmented by large monastic and other royal grants. With Cromwell's creation as earl of Essex, his appointment as lord great chamberlain, and his son Gregory's marriage into the Seymour family (becoming thereby uncle to the future Edward VI), the uninitiated might well be pardoned for seeing here the origin of still one more powerful landed political dynasty which, like the Seymours themselves, the Russells, the Paulets, and the Cecils, owed its beginning to political skill and the opportunities of a fluid sixteenth-century land market.
Certainly this new style of service aristocracy, founded first on office in the central government and concentrating on London and the court, with landed wealth frequently coming later as a reward rather than first as a birthright, was perfectly consistent with the major realignment of relations between king and nobility which characterized the reigns of the first two Tudor monarchs and their leading ministers.
