About the Book

"King and Emperor takes on the compelling suspense of good detective work as well as good history."—The Wall Street Journal

Charles I, often known as Charlemagne, is one of the most extraordinary figures ever to rule an empire. Driven by unremitting physical energy and intellectual curiosity, he was a man of many parts, a warlord and conqueror, a judge who promised "for each their law and justice," a defender of the Latin Church, a man of flesh and blood. In the twelve centuries since his death, warfare, accident, vermin, and the elements have destroyed much of the writing on his rule, but a remarkable amount has survived. Janet Nelson's wonderful new book brings together everything we know about Charles I, sifting through the available evidence, literary and material, to paint a vivid portrait of the man and his motives.
 
Building on Nelson’s own extraordinary knowledge, this biography is a sort of detective story, prying into and interpreting fascinating and often obdurate scraps of evidence, from prayer books to skeletons, gossip to artwork. Charles’s legacy lies in his deeds and their continuing resonance, as he shaped counties, countries, and continents; founded and rebuilt towns and monasteries; and consciously set himself up not just as King of the Franks, but as the head of the renewed Roman Empire. His successors—even to the present day—have struggled to interpret, misinterpret, copy, or subvert his legacy. Janet Nelson gets us as close as we can hope to come to the real figure of Charles the man as he was understood in his own time.

Reviews

"A deeply learned and humane portrait . . . Nelson’s King and Emperor brings alive the age of Charlemagne, the ruler usually associated with the first effort after the fall of Rome to unite Europe under a single rule. This 'new life' is a bold book. . . . Each chapter is a masterclass in tracing specific bodies of evidence back to the persons or incidents from which they arose. . . . King and Emperor is a masterpiece of historical writing and a robust step toward filling the gap in our historical imagination left by the passing of Rome."
New York Review of Books
"A deeply learned and humane portrait of Charlemagne, a man who wielded supreme power in much of Europe three centuries after the fall of Rome. . . . Nelson’s King and Emperor brings alive the age of Charlemagne, the ruler usually associated with the first effort after the fall of Rome to unite Europe under a single rule. This 'new life' is a bold book. . . . Each chapter is a masterclass in tracing specific bodies of evidence back to the persons or incidents from which they arose. . . .

New York Review of Books
"Janet Nelson assembles an astonishingly rich picture from the most unrewarding of texts. The way she puzzles out probable facts and motivations, based on a complete reading of the existing texts, is a joy to witness. She draws on and shows off the clever work of earlier historians, while giving short shrift to their more biased assumptions. The narrative voice emerges as that of a patient, inquisitive, incisive and helpful master detective, with funny asides, a beautiful style and sensible politics."
Times Literary Supplement
"There have been countless studies of Charlemagne in many languages . . . but few have been as ambitiously biographical as Nelson’s. Historians of early medieval Europe are trained to interpret scattered clues and fragments, however, and Nelson is one of the very best."
London Review of Books

"King and Emperor takes on the compelling suspense of good detective work as well as good history. . . . Janet L. Nelson comes as close as one can to approaching this extraordinary man."
Wall Street Journal
“Janet Nelson has succeeded in delivering 'a new life' of Charles. Her long-awaited biography invites us to understand the man in ways that are original and penetrating.”
Financial Times
"In her impressive new biography, Janet L Nelson meticulously sifts all the available evidence [on Charlemagne]. At the start she notes (a little terrifyingly) that some 7,000 charters survive from his reign. You can believe she has looked at every single one, so thorough and expansive is this work of scholarship. . . . Nelson uses literary sources adroitly, supplementing more prosaic charter and annalistic evidence with moving poetry."

Speculum
"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
