Liutprand was the king of the Lombards from 712 to 744 and is chiefly remembered for his multiple phases of law-giving, in fifteen separate sessions from 713 to 735 inclusive, and his long reign, which brought him into a series of conflicts, mostly successful, with most of Italy. He is often regarded as the most successful Lombard monarch, notable for the Donation of Sutri in 728, which was the first accolade of sovereign territory to the Papacy. Early life Liutprand's life began inauspiciously. His father was driven to exile among the Bavarians, his older brother Sigipert was blinded by Aripert II, king of the Lombards, and his mother Theodarada and sister Aurona were mutilated (their noses and ears were cut off). Liutprand was spared only because his youth made him appear harmless, described as adolescens in Paul the Deacon's Historia Langobardorum (Book VI, xxii), suggesting that he was 'probably older than 19 but still in his twenties'. He was released from Aripert II's custody and allowed to join his father. Reign The reign of Liutprand, son of Ansprand, duke of Asti and briefly king of the Lombards, began the day before his father's death when magnates called to Ansprand's deathbed consented to make Liutprand his colleague. Liutprand's reign endured for thirty-one years. Within the Lombard kingdom he was considered a lawgiver of irreproachable Catholicity. He was the brother of Imberg, whom he appointed ruler of Asti. Relations with the Agilolfings of Bavaria At the opening of his reign, Liutprand's chief ally among neighboring rulers was the Agilolfing Theodo I, the Frankish duke of Bavaria. Theodo I's intervention on Ansprand's behalf helped him gain the throne. Theodo had taken him in, when he and his father were temporarily expelled by Aripert II in 702, and the hospitality was later cemented with a marriage connection: Liutprand took to wife the Agilolfing Guntrud. The core of Theodo's policy was resistance to the Merovingian mayors of the palaces in their encroachments north of the Alps, concerns that did not much occupy Liutprand, and maintaining strategic control of the eastern Alpine passes in what is now the Italian Alps, which did. In the spring of 712, Theodo's son Theodebert, with Ansprand and Liutprand, attacked Lombard strongholds, and with the drowning of their fleeing rival Aripert, Ansprand's faction were back in power at Pavia. Theodo died in 717 or 718; under his successor the Lombard ties
