Vitellius (September 24, 15 - December 22, 69) Vitellius was proclaimed 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. He was the first to add the honorific cognomen Germanicus to his name instead of Caesar upon his accession. His claim to the throne was soon challenged by legions stationed in the eastern provinces, who proclaimed their commander Vespasian emperor instead. War ensued, leading to a crushing defeat for Vitellius at the Second Battle of Bedriacum in northern Italy. Once he realized his support was wavering, Vitellius prepared to abdicate in favor of Vespasian, but was executed in Rome by Vespasian's soldiers on December 22, 69.
