799 CE
Pope Leo III is physically attacked by a band of aristocratic conspirators, under the leadership of a public official who is a nephew of the late Pope Adrian I. After mistreatment and attempted disfigurement by the citizens of Rome, Leo flees to the court of King Charlemagne at Paderborn (modern Germany) to seek protection. He sends him back with Frankish agents, and restores him to the papal throne. Autumn – Siege of Trsat: Višeslav, prince or duke of Dalmatian Croatia, decisively defeats an invading Frankish army under Eric of Friuli, during the siege at the fortress city of Trsat (Rijeka). The Vikings raid the island of Noirmoutier, and attack the monastery of Saint Philibert of Jumièges.
