"Vitellius was Roman Emperor for eight months, from 16 April to 22 December 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. Vitellius was the first to add the honorific cognomen Germanicus to his name instead of Caesar upon his accession; the latter name had fallen into disrepute in many quarters because of the actions of Nero. 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 realised his support was wavering, Vitellius prepared to abdicate in favor of Vespasian, but was executed in Rome by Vespasian's soldiers on 22 December 69."
