Adalbert I of Ivrea

Adalbert I (died 17 July 923 or 8 October 924) was the son of Anscar of Ivrea and, from his death in 902, margrave of Ivrea.

He rebelled against Berengar I in 905 in support of Louis III. When Louis was defeated, captured, and blinded, Adalbert was exiled to Burgundy, whence his family had originated. He later returned and rebelled against, this time with Lambert, Archbishop of Milan, in support of another rival for the Italian throne: Rudolf II of Burgundy. Initially unsuccessful, he and Rudolf jointly defeated Berengar at the Battle of Firenzuola on 29 July 923.

He married firstly, before 900, Gisela of Friuli, a daughter of Berengar I of Italy and Bertila of Spoleto. With her, he had two children:
*Berengar, successor
*Bertha, abbess of Modena

Around 915, he married Ermengard, the daughter Adalbert II of Tuscany and Bertha, daughter of Lothair II. From this marriage he had a second son, Anscar, Duke of Spoleto.
