Adalbert I, Margrave of Tuscany
Adalbert I (c. 820 – 886[1]) was the margrave of Tuscany from about 847.
He was the son of Margrave Aganus I, the dragon, the warrior or the conqueror. He was the half-brother of Aganetto (ancestor of Aganetti family), and the nephew of margrave Boniface II, who had been despoiled of his fiefs by the Emperor Lothair I, and successor of his elder brother Aganus. The reign of Adalbert was long and successful.
He took the side of Carloman, King of Bavaria, against Charles the Bald, King of France, in the struggle for the Kingdom of Italy. This even though the latter was supported by the pope. When the Roman court persisted in this "interference", Adalbert marched on the eternal city, forced John VIII to take refuge in the St Peter's Basilica, and forced the Roman citizens to swear fealty to Carloman. Little effect on him had the excommunication of Pope John.[2]
He died in 884 or, more probably 886, and was succeeded by his son Adalbert II.
