In 955 Lothair and Hugh the Great together took Poitiers by siege. With Hugh the Great's death in 956 Lothair, only fifteen, came under the guardianship of his maternal uncle Bruno, archbishop of Cologne, brother of East Francia's king Otto I. With Bruno's advice, Lothair mediated between Hugh's sons – Hugh Capet and Otto, Duke of Burgundy. The King gave Paris and the title of "dux francorum" (Duke of the Franks) to Hugh Capet, and invested Otto with the Duchy of Burgundy in 956.
