Abstract: | The Bellême family were among the most important of the new families to emerge in the unsettled conditions of northern France in the tenth century. They illustrate well the manner in which those families extended their influence at the expense of declining central authorities. The nature of their relations with their overlords, the counts of Maine and the dukes of Normandy, is examined and a new chronology proposed for the complex divisions of estates among the family. It is suggested that family quarrels of the 1040s and 1050s seriously weakened their position and that the lordship was easily dominated by Geoffrey Martel, count of Anjou, the most powerful figure in mid-eleventh century northern France. A reversal is traced in the pro-Angevin sympathies of Bishop No of Sées, the last surviving male member of the family, after the failure of the coalition of Angevins and Capetians against the duke of Normandy in 1054. However, it was not until the estates of the family were eventually reunited in 1071 on the succession of Ivo's niece, Mabel, and her Norman husband, that the lordship came completely under the influence of the ascendant Normandy. |
