Aristocratic patronage,political networking and the shaping of a private sanctuary: Countess Clemence of Flanders and the early years of Bourbourg Abbey (c.1103–21)

This article discusses the geopolitical manoeuvres of the comital House of Flanders, especially of Countess Clemence of Burgundy, to consolidate comital influence and power in the border region of western Flanders, specifically in the area of Bourbourg. By analysing and mapping the shifting patterns of interaction between alliances of both secular and ecclesiastical stakeholders in the charters issued for the abbey of Bourbourg, a female house, during the first decades of the twelfth century, it argues that the foundation and patronage of Bourbourg were engineered to create a symbolic and geo-strategic key site where the interests of the counts of Flanders and their local representatives, the abbot of Saint-Bertin, and members of the local elite converged, and alliances balanced each other. Moreover, through an anthropological approach in which the charters are also considered within the supra-institutional context of the reform movement, this study offers new insights into the dynamic role of Countess Clemence as a promoter and benefactor of Bourbourg Abbey, and also as a manager of her personal network of allies.
