Grimoald was the younger son of Arichis II and became duke after the death of his father. At the beginning he was a vassal of Charlemagne, the Frankish king, and together they defeated the Byzantines in Sicily, helping Desiderius' son, Adalgis. Soon after, wishing to maintain his independence, Grimoald III resumed the title of Princeps. (NAC 93, 1335 note).
