The events surrounding the administration of the patrimony of Ageltrude, member of the house of Benevento and wife of the first non Carolingian emperor in Italy, is uneven from a documentary perspective and can thus be reconstructed in its articulations only by weighing large quantities of information. Ageltrude could administrate her dower composed of fiscal goods bestowed by Guido, of the dukes of Spoleto, and by her son Lambert, for a very brief period of time and during a particularly conflict-ridden phase such as the last decade of the 9th century. Yet, if one observes the potential inherent in the administration of fiscal goods, it can be noted that despite the presence of substantial property in Pavia, this patrimony is far too concentrated to be used as a stepping stone for a policy of consolidation and to activate relationships. This function is fulfilled by other scattered goods transmitted to Ageltrude and above all through the introduction into a system of relationships of which only fragments can be appreciated. The former empress strenuously pursues a project, initiated by Guido and Lambert, aimed both towards personal consolidation and the support of the front opposed to emperor Berengar.
