Vitellius (Latin: Aulus Vitellius Germanicus Augustus; September 24 , 15 – December 22,69), is Roman Emperor for eight months, from 16 April to 22 December 69.

Vitellius is acclaimed 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 is 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 is soon challenged by legions stationed in the eastern provinces, who proclaim their commander Vespasian emperor instead.

War ensues, leading to a crushing defeat for Vitellius at the Second Battle of Bedriacum in northern Italy.

Once he realizes his support is wavering, Vitellius prepares to abdicate in favor of Vespasian, but is executed in Rome by Vespasian's soldiers on December 22 of 69.
