This book is a detailed study of Hugh of Flavigny and his chronicle, which is widely recognised as one of the most important narratives of a crucial period of European history, the Investiture Contest. Hugh's Chronicon is significant in a number of ways: as a unique source-book for some of the most important primary documents (especially papal letters) generated by the Investiture Contest; as a rare autograph manuscript which gives an important insight into contemporary modes of composition and compilation; as an important history of the 'local' effects of the Investiture Contest in the dioceses of Verdun and Autun; and as a striking autobiography of the author, Hugh of Flavigny.
