First full English translation of the 12C Chronicle of Hainaut, offering fascinating insights into European history of the time. The importance of the late twelfth-century Chronicle of Hainaut (Chronicon Hanoniense) as an historical record cannot be overestimated. Gilbert of Mons was an eye-witness to important events affecting Count Baldwin V of Hainaut, and provides much significant information about persons and affairs within France and the Empire, particularly Count Philip of Flanders, King Philip Augustus and Emperor Frederick Barbarossa; he had a keen interest in noble marriages, making his chronicle an unmatched source for genealogical and prosopographical material for this region. Moreover, his work is a mine of information on a great many subjects, such as the crusades, political events, noble women, the lives of saints, lord-tenant relationships, customary practices and the association of churches with lay advocates; it is particularly informative on military matters, giving detailed accounts of sieges, campaigns and tournaments. This volume presents a clear translation, accompanied by detailed annotations, clarifying the text, and identifying people, events and concepts, an introduction, and bibliography.
