Of all Eleanor of Aquitaine's daughters, her namesake was the only one who was enabled, by political circumstances, to wield the kind of influence her mother had exercised. In her own marriage treaty, and in the first marriage treaty for her daughter Berengaria, Eleanor was given direct control of many lands, towns, and castles throughout the kingdom. She was almost as powerful as Alfonso, who specified in his will in 1204 that she was to rule alongside their son in the event of his death, including taking responsibility for paying his debts and executing his will. It was she who persuaded him to marry their daughter Berengaria to Alfonso IX of León. Troubadours and sages were regularly present in Alfonso VIII's court due to Eleanor's patronage.
