Events
Charlemagne spends Easter (April 14) in Treviso after putting down a revolt by Friuli and Spoleto, removing Hrodgaud, the Duke of Friuli, from power, and signing a treaty with Hildeprand, the Duke of Spoleto. Co-conspirators in the revolt were Arechis, Duke of Benevento, and Adelchis, the son of Desiderius. Charlemagne had defeated Desiderius two years earlier, and Adelchis had fled to Byzantium. Arechis was not defeated in this action by Charlemagne, and Adelchis never left Byzantium to provide any support to the revolt.
