 Due to his vast military conquests, Charles often reallocated existing land settlements, including Church property, to new tenants.Ecclesiastical property and monasteries in the late Merovingian and Carolingian period were political centres and often closely related to the royal court; as such they often became involved in political matters, which often overlapped with Charles' reallocation of land.This 'secularisation' of Church property caused serious tension between the Carolingian church and state, and often gave Charles a negative depiction in ecclastical sources.
