«[The author is] a giant in the field, who knows that myths concerning Charlemagne, which began before his corpse grew cold, are difficult to lay to rest.»

H-France Review

«This is a terrific book ... It is lovely to read, in part because it is so lightly written ... One leaves Jinty Nelson's book with the sense that one does, yes, get from it a sense of what Charlemagne was actually like. Which is what biographies are for, and why this is one to read.»

Chris Wickham, History Today

«An imaginative, deeply thoughtful, often provocative, always important book.»

Geoffrey Koziol, Professor of History at UC Berkeley

«An immense achievement - brilliantly learned and profoundly wise, it is as revelatory about the practise of history as it is about the great man himself.»

Helen Castor, BBC History Magazine

«Nelson assembles an astonishingly rich picture from the most unrewarding of texts. The way she puzzles out probable facts and motivations is a joy to witness ... The narrative voice emerges as that of a patient, inquisitive, incisive and helpful master detective, with funny asides, a beautiful style and sensible politics.»

Bettina Bildhauer, Times Literary Supplement

«This is a remarkable book: at once the dramatic story of a truly extraordinary man, and a masterclass in the practice of history from a superlative historian. Janet Nelson's brilliant insight illuminates a world that is both familiar and strange, and full of resonances between past and present. Here - seen through challenging sources, sifted and weighed with wisdom and wit - is everything we can know, twelve centuries on, about the king and emperor called Charlemagne.»

Helen Castor, author of SHE-WOLVES and JOAN OF ARC

«Christianity entered a new era in 800 when Charles, King of the Franks, became the first Holy Roman Emperor, and entrenched the faith in European civilisation. His story is told in Janet L Nelson's outstanding King and Emperor.»
