Adalbert (c.?936–971) was the Margrave of Ivrea (as Adalbert II) and ajoint king of Italy with his father from 950 to 961.

Adalbert, born c.?936 was the son of the Margrave Berengar of Ivrea andWilla.[1] In 950, both he and his father were crowned kings of Italyafter the death of Lothair II.[2] His father tried to force Adelaide,widow of Lothair, to marry Adalbert and cement their claim to thekingship. When she refused and fled, she was tracked down and imprisonedfor four months at Como.[3]

In 951, King Otto I of Germany invaded Italy and rescued Adelaide,marrying her himself.[4] He forced Berengar and Adalbert to do homage tohim for their kingdom in 952. In 953, Adalbert began besieging CountAdalbert Azzo of Canossa, in his Canossan castle, where Adelaide hadtaken refuge two years prior. In 957, Liudolf, Duke of Swabia, invadedLombardy and caused Berenagar to flee, though Adalbert gathered a largeforce at Verona. He was defeated, but Liudolf died prematurely and hisarmy left.

In 960, he joined his father in attacking the pope, John XII. Otto camedown at the pope''s call and defeated the two co-kings and was crownedEmperor.[5] When Otto drove him out of Italy Adalbert fled toBurgundy.[5] From there he fled to Corsica. When he returned, he tried totake Pavia, the Italian capital, but was defeated by another invadingSwabian army, this time under Burchard III. Only the interference of hisbrothers Conrad and Guy, who died fighting, saved him to fight anotherday, which he never did. His negotiations with the Byzantine Empire fellthrough and he retired with his wife Gerberga to Burgundy. Adalbert diedat Autun on 30 April 971.[1]

Adalbert married, c.?956 Gerberga, Countess of Mâcon.[1] They had a son:
