Aulus Vitellius was Roman emperor, ruling for eight months from 19 April to 20 December AD 69. Vitellius became emperor following the quick succession of the previous emperors Galba and Otho, in a year of civil war known as the Year of the Four Emperors. Vitellius added the honorific title Germanicus to his name instead of Caesar upon his accession. Like his predecessor, Otho, Vitellius attempted to rally public support to his cause by honoring and imitating Nero who remained popular in the empire.
