Berengar II ( 900 – 4 August 966) was the King of Italy from 950 until his deposition in 961. He was a scion of the Anscarid and Unruoching dynasties, and was named after his maternal grandfather, Berengar I. He succeeded his father as Margrave of Ivrea around 923 (whence he is often known as Berengar of Ivrea), and after 940 led the aristocratic opposition to kings Hugh and Lothair II. In 950 he succeeded the latter and had his son, Adalbert crowned as his co-ruler. In 952 he recognised the suzerainty of Otto I of Germany, but he later joined a revolt against him. In 960 he invaded the Papal States, and the next year his kingdom was conquered by Otto. Berengar remained at large until his surrender in 964. He died imprisoned in Germany two years later. Ruling Ivrea (923–50) Berengar was a son of Margrave Adalbert I of Ivrea and his wife Gisela of Friuli, daughter of the Unruoching king Berengar I of Italy. He succeeded his father as margrave about 923 and married Willa, daughter of the Bosonid margrave Boso of Tuscany and niece of King Hugh of Italy. The chronicler Liutprand of Cremona, raised at Berengar's court at Pavia, gives several particularly vivid accounts of her character. About 940 Berengar led a revolt of Italian nobles against the rule of his uncle. To evade an assault by Hugh's liensmen, he, forewarned by the king's young son Lothair, had to flee to the court of King Otto I of Germany. Otto avoided taking sides; nevertheless, in 945 Berengar was able to return to Italy with hired troops, welcomed by the local nobility. Hugh was defeated and retired to Arles, and he was nominally succeeded by Lothair. From the time of Berengar's successful uprising, all real power and patronage in the Kingdom of Italy was concentrated in his hands, with Hugh's son Lothair as titular king. Lothair's brief reign ended upon his early death in 950, presumably poisoned. Ruling Italy (950–61) Berengar then assumed the royal title with his son Adalbert as co-ruler and were crowned in Pavia, in the Basilica of San Michele Maggiore. He attempted to legitimize his kingship by forcing Lothair's widow Adelaide, the respective daughter, daughter-in-law, and widow of the last three Italian kings, into marriage with Adalbert. However, the young woman fiercely refused, whereafter Berengar had her imprisoned at Garda Castle, allegedly
