Year 455 (CDLV) was a common year starting on Saturday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Valentinianus and Anthemius (or, less frequently, year 1208 Ab urbe condita). The denomination 455 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
Events
By place
Roman Empire
- March 16 – Emperor Valentinian III, age 35, is assassinated by two Hunnic retainers of the late Flavius Aetius, ending the Theodosian Dynasty. Also his primicerius sacri cubiculi, Heraclius, is murdered. Valentinian is killed while training with the bow on the Campus Martius (Rome).
- March 17 – Petronius Maximus, former domesticus ("elite bodyguard") of Aetius, becomes with support of the Roman Senate emperor of the Western Roman Empire. He secures the throne by bribing officials of the imperial palace. Maximus consolidates his power by a forced marriage with Licinia Eudoxia, widow of Valentinian III.
- Maximus appoints Avitus, most trusted general, to the rank of magister militum and sends him on an embassy to Toulouse to gain support of the Visigoths. He elevates his son Palladius to Caesar and has him marry Eudocia, eldest daughter of Valentinian III.
- May 31 – Maximus is stoned to death by an angry mob while fleeing Rome. A widespread panic occurs when many citizens heard the news that the Vandals were plundering the Italian mainland.
- June 2 – Sack of Rome: King Genseric leads the Vandals into Rome after he has promised pope Leo I not to burn and plunder the city. Genseric sacks the city for a period of two weeks. Eudoxia and her daughters, Eudocia and Placidia, are taken hostage. The loot is sent to the harbour of Ostia and loaded into ships, from where the Vandals depart and return to Carthage.
- July 9 – Avitus is proclaimed Roman emperor at Toulouse, and later recognised by the Gallic chiefs in Viernum (near Arles).
