In the intermittent civil war which affected Italy from 888 into the 930s, Adalbert initially strove to remain neutral, but from 901 on he sided sequentially with every claimant to the Italian throne.
Although Adalbert is not recorded as being related to the king in any of Berengar's charters down through 14 August 908 and his marriage is not explicitly referenced before 13 June 910, it must have taken place some fifteen years before he and Gisela's eldest son were granted a county and a missaticum in 918.
In 920–921 he joined those noblemen, many of Burgundian origin like him, who supported the candidature of King Rudolf II of Burgundy for the Italian throne.
[1] Adalbert, with Lambert, Archbishop of Milan, and Count Gilbert of Bergamo, assembled a force in the mountains outside Brescia with the intention of marching on Verona and capturing Berengar there.
His last recorded action, probably shortly before he died, was a donation to the church of Saint Andrew in Turin, which was witnessed by King Hugh on 28 February 929.
