Hubert had one full brother named Boso, who became a bishop.[1] Hubert was made Margrave of Tuscany by his father in 936, after the deposition of his uncle Boso. In 942 he was made a count palatine. In 943 Sarlio, duke of Spoleto, was removed from office for killing the previous duke, Anscar, in battle during a quarrel that was possibly orchestrated by the king, who promptly placed his bastard son in the ducal office vacated by Sarlio.[2]
After his fellow margrave, Berengar of Ivrea, became king in 950, Hubert was deprived of Spoleto, but allowed to keep Tuscany. He was the most powerful vassal in central Italy, and remained loyal to Berengar when Otto I of Germany crossed the Alps and took over the kingdom. After Berengar's final defeat, Hubert was reconciled to Otto and allowed, once again, to keep Tuscany.[2]
