d.0788 İstanbul, İstanbul, Turkey
Facts and Events
Adalgis or Adelchis (died 788) was an associate king of the Lombards from August 759, reigning with his father, Desiderius, until their deposition in June 774. His mother was Ansa. He is remembered today primarily as the hero of the play Adelchi (1822) by Alessandro Manzoni.
When in 773 the Lombard kingdom was invaded by Charlemagne, the king of the Franks, Desiderius stayed in Pavia, the capital, where he unsuccessfully resisted a siege. Adalgis instead took refuge in Verona, where he sheltered the widow and children of Charlemagne's younger brother, Carloman I, who had entered an Italian monastery after abdicating the kingship. Even before the fall of Pavia, when the Frankish army approached Verona, Adalgis did not resist. He escaped to Constantinople, where he was received by the Byzantine emperor Constantine V, who raised him to the patriciate.
Adalgis hoped to return to re-conquer Italy, and solicited help from Duke Arechis II of Benevento for this purpose. Many Lombards refused to submit to Frankish rule, believing that Adalgis's return was imminent. The historian Paul the Deacon reflected a widespread belief among the Lombards when he wrote, as part of his poetic epigraph for the tomb of Ansa, that "in her, by Christ, the greatest hope of the Lombards spent a time." Einhard, Charlemagne's biographer, also records that "on [Adalgis] all hope seemed to incline" (in quem spes omnium inclinatae videbantur).
Only in 787, after the efforts of the Empress Irene to obtain the hand in marriage of Charlemagne's daughter Rotrude for her son, Constantine VI, did the Byzantines move to give Adalgis the military assistance he required. An expeditionary corps was placed under the command of the saccellarius and logotheta Ihoannes and augmented by troops from Sicily under the patrikios Theodoros. The Byzantine army landed in Calabria towards the end of 788, but was met by the united armies of the Lombard dukes Hildeprand of Spoleto and Grimoald III of Benevento, who had succeeded his father, Arechis, and made peace with the Franks. These Lombard forces were accompanied by Frankish troops under Winiges. In the ensuing battle the Byzantines were defeated, but there is no further record of the fate of Adalgis.
