Overview
Adalbert (born 932/936, died 971/975) was the king of Italy from 950 until 961, ruling jointly with his father, Berengar II. After their deposition, Adalbert continued to claim the Italian kingdom until his defeat in battle by the forces of Otto I in 965. Since he was the second Adalbert in his family, the Anscarids, he is sometimes numbered Adalbert II. His name is occasionally, especially in older works, shortened to Albert.
Accession
Adalbert was born between 932 and 936, the son of Berengar, then margrave of Ivrea, and Willa, daughter of Boso, margrave of Tuscany. In 950, he and his father were simultaneously elected by the high nobility to succeed King Lothar II of Italy. They were crowned together in the basilica of Saint Michael in Pavia on 15 December. Berengar tried to force Lothair's widow, Adelaide, to marry Adalbert and cement their claim to joint kingship. Although later traditions speak of a marriage, Adelaide refused to be married and fled to Canossa. She was tracked down and imprisoned for four months at Como.
German invasion
In 951, King Otto I of Germany invaded Italy, forcing the release of Adelaide and marrying her himself. He made no effort to depose the kings of Italy, however. Instead, Adalbert and Berengar were compelled to attend the Diet of Augsburg in Germany in August 952, where Otto formally invested them with the kingdom of Italy, thus subjecting the kingdom to Germany. Between 953 and 956, Adalbert and Berengar besieged Count Adalbert Azzo of Canossa in his castle, where Adelaide had taken refuge in 951. In 956, Duke Liudolf of Swabia, Otto's son, entered Italy with a large army to re-assert his father's authority. Adalbert gathered a large force to oppose him. He defeated Liudolf, but before the latter could return to Germany he died in September 957. Following this victory, Adalbert, assisted by Duke Hugh of Tuscany, campaigned against Duke Theobald II of Spoleto. During this campaign his forces even encroached on Roman territory in 960.
Pope John XII asked the king of Germany for help against Adalbert. Otto entered Italy in 961, while Adalbert assembled a large army at Verona. According to contemporary sources it was 60,000 strong, although this is an obvious exaggeration. Many of the leading noble families refused to join in the defence of Italy except on the condition that Berengar abdicate in favour of his son.
