François-Louis Ganshof

François-Louis Ganshof (14 March 1895, Bruges – 26 July 1980, Brussels) was a Belgian medievalist. After studies at the Athénée Royal, he came to the University of Ghent, where he came under the influence of Henri Pirenne. After studies with Ferdinand Lot, he practiced law for a period, before returning to the University of Ghent. Here he succeeded Pirenne in 1930 as professor of medieval history, after Pirenne left the university as a result of the enforcement of Dutch as language of instruction. He remained there until his retirement in 1961.

Ganshof's work was primarily on Flanders in the Carolingian period. His best known book is Qu'est-ce que la féodalité? (1947). Here he defines feudalism narrowly, in simple legal and military terms. Feudalism, in Ganshof's view, existed only within the nobility. This contrasts with the later ideas of Marc Bloch, where feudalism encompasses society as a whole, and those of Susan Reynolds, questioning the concept of feudalism in itself.

Though Ganshof's definition is not always accepted today, this book was not his only work. He contributed greatly to his field, mostly through articles. Among the few books he published were Les Destinées de l'Empire en occident de 395 à 888 (1928) and Flandre sous les premiers comtes (1943). In 1946 he received the Francqui Prize for Human Sciences.

Ganshof was renowned as the greatest European expert on the Frankish kingdoms, particularly under the Carolingian dynasty; he never wrote the definitive biography of Charlemagne that everyone expected of him, but his contributions to Frankish history continue to be fundamental. The best English-language introduction to this (very major) aspect of his work is in F.L. Ganshof, The Carolingians and the Frankish Monarchy. Studies in Carolingian History, tr. Janet Sondheimer (London: Longman, 1971). This collection of major articles ends with an exhaustive bibliography of Ganshof's writings on Merovingian and Carolingian history down to 1970.
