Henry VI (1422-61) was one of the most spectacularly inadequate kings of England, and his reign dissolved into the conflict known as the Wars of the Roses. Yet he held on to his throne for thirty-nine years and, for almost thirty of them, without much difficulty. What was the nature of Henry's inadequacy, and why did it have such ambivalent and complicated results? This book looks intensively at the political system itself, rather than at individuals, their personalities and patronage networks, and thus offers the first truly structured narrative of the reign.
