He was Marquis of Ivrea from 900 to 929. KING BERENGER I had his army annihilated by the Hungarians. In 900, perceiving BERENGER's weakness, the nobles of northwest Italy, led by Adalbert, revolted and elected LOUIS OF PROVENCE (i.e. KING LOUIS III) as king. Italian politics during Adalbert's lifetime centered around the power struggle between the German faction, which had supported
BERENGER, and the French faction. Adalbert was of the French faction. Adalbert married BERENGER's daughter, GISELE. They became the parents of KING BERENGER II.
