David Carpenter is professor of medieval history at King’s College London. He is the author of numerous books including a new study of Magna Carta for the Penguin Classics series.

“[A] monumental, awesome yet highly readable book…Carpenter is the foremost scholar of England’s 13th century, and his spectacular erudition shines on every page. . . . Above all, he has narrative gifts that root this history of our medieval country in reality rather than in romance, and makes the lives of our distant forebears feel as comprehensible as our own.”—Simon Heffer, Daily Telegraph“Professor Carpenter is one of Britain’s foremost medievalists. . . . No one knows more about Henry, and a lifetime of scholarship is here poured out, elegantly and often humorously. This is a fine, judicious, illuminating work that should be the standard study of the reign for generations to come.”—Dan Jones, Sunday Times“[A] major new biography.”—BBC History Magazine“Carpenter’s view of Henry is essentially a benign one: he sees him as a generous and well-meaning man. . . . It is a persuasive view. This is a magisterial biography, authoritative and yet accessible.”—Nigel Saul, History Today“[F]ull of good judgment in good prose.”—Christopher Howse, Spectator, “Books of the Year”“A monumental biography . . . written in a blithe and energetic style, its narrative thread tracing the intrigues and intricacies of England’s first Plantagenet king.”—E. Andrew Darden, Aspects of History“Carpenter’s ability to grapple with something so enigmatic as a monarch’s character, particularly that of a medieval monarch, is convincing and compelling. . . . Carpenter has crafted something that very many of us can delight in.”—Benjamin Linley Wild, Royal Studies Journal“Few biographers of a medieval individual, however, can have got closer to their subject than Professor David Carpenter. . . . Carpenter infuses what will surely become the standard biography of England’s longest reigning medieval king with personal insights that add richness, colour and humour to a monumental 763-page study. Indeed, the author’s own personality drips from every page as much as that of his subject.”—Paul Dryburgh, Mortimer History Society Journal“Carpenter has created a valuable resource for those who wish to advance the scholarship of the period, illuminating new avenues in the study of kingship and thirteenth-century England, through his enduring passion for the topic and considerable expertise. It stands as the most significant modern addition to scholarship on Henry III and to the broader corpus of royal biographies, which will surely inspire others to explore his reign.”—Louis Pulford, Journal of Ecclesiastical History of Books“The whole period covering Henry’s minority and his emergence into personal rule is fascinating in its own right and deserves the close-focus treatment that Carpenter gives it.” —Ferdinand Mount, London Review of Books  “Outstanding. Through sustained scholarship Carpenter provides the reader with all sorts of insights into the decisions and daily experience of this ambitious and complex medieval king.”—Michael Clanchy, author of England and its Rulers“This brilliant study by a leading historian of medieval England brings together a lifetime of research in a masterly way. Henry III is treated with humane understanding while his political failings and absence of a proper sense of priorities are emphasised with admirable clarity. Vivid and highly readable, this is a book of major significance.”—Michael Prestwich, author of Edward I “Rooted in his unrivalled understanding of the primary sources, Carpenter has created a sparkling and compelling narrative of this little-known English king.”—Stephen Church, author of Henry III“A monumental achievement. Never before has England’s place in the wider history of medieval Europe been revealed on quite this epic scope, and with so sharp an eye for personalities. Revisiting fifty years of history, Carpenter reveals Henry III—a supposedly ‘non-descript king’—as one of the more fascinating failures ever to have sat on the English throne.”—Nicholas Vincent, author of A Brief History of Britain 1066–1485
