ベレンガーリオ2世
Adalbert first appears in sources as a son of Sigifred of Lucca. He was originally a vassal of King Lothair II and a legionary of Adelard, Bishop of Reggio. He rose to prominence rapidly by sheltering Adelaide of Italy in his castle at Canossa after she fled from the castle of Garda (951), where Berengar II of Italy had imprisoned her.
