Sentence (from "Amadeus VII, Count of Savoy"): Amadeus VII left the important role of guardian of his son and heir, Amadeus VIII, to his own mother, a sister of the powerful Duke de Bourbon, instead of following the tradition of appointing the child's mother, who was a daughter of the equally powerful Duke de Berry.
