Berengar’s younger daughter, Gisela, had married Adalbert…

Berengar’s younger daughter, Gisela, had married Adalbert I of Ivrea as early as 898 (and no later than 910), but this had failed to spark an alliance with the Anscarids.

She was dead by 913, when Adalbert remarried.

Adalbert, one of Berengar's earliest internal enemies after the defeat of Louis of Provence, has called on Hugh of Arles between 917 and 920 to take the Iron Crown.

Hugh had invaded Italy, with his brother Boso, and advanced as far as Pavia, where Berengar had starved them into submission, but allowed them to pass out of Italy freely.

Dissatisfied with the emperor, who had ceased his policy of grants and family alliances in favor of paying Magyar mercenaries, several Italian nobles—led by Adalbert and many of the bishops—invite Rudolph II of Upper Burgundy, king from 912, to take the Italian throne in 921.

Moreover, his own grandson, Berengar of Ivrea, rises up against him, incited by Rudolph.
