Year **455** (**[CDLV](/source/Roman_numerals)**) was a [common year starting on Saturday](/source/Common_year_starting_on_Saturday) of the [Julian calendar](/source/Julian_calendar). At the time, it was known as the **Year of the Consulship of [Valentinianus](/source/Valentinian_III) and [Anthemius](/source/Anthemius)** (or, less frequently, **year 1208 *[Ab urbe condita](/source/Ab_urbe_condita)***). The denomination 455 for this year has been used since the early medieval period, when the [Anno Domini](/source/Anno_Domini) [calendar era](/source/Calendar_era) became the prevalent method in Europe for naming years.

He secures the throne by bribing officials of the imperial palace. Maximus consolidates his power by a forced marriage with [Licinia Eudoxia](/source/Licinia_Eudoxia), widow of Valentinian III.

- Maximus appoints [Avitus](/source/Avitus), most trusted general, to the rank of *[magister militum](/source/Magister_militum)* and sends him on an [embassy](/source/Diplomatic_mission) to [Toulouse](/source/Toulouse), to gain the support of the [Visigoths](/source/Visigoths). He elevates his son [Palladius](/source/Palladius_(Caesar)) to *[Caesar](/source/Caesar_(title))* and has him marry [Eudocia](/source/Eudocia_(daughter_of_Valentinian_III)), eldest daughter of Valentinian III.

Genseric sacks the city for a period of two weeks. Eudoxia and her daughters, Eudocia and [Placidia](/source/Placidia), are taken hostage. The [loot](/source/Looting) is sent to the harbour of [Ostia](/source/Ostia_Antica) and loaded into ships, from whence the Vandals depart and return to [Carthage](/source/Carthage).
