Vitellius (Latin: Aulus Vitellius Germanicus Augustus; 24 September 15 – 22 December 69) 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.
He was the son of Lucius Vitellius Veteris and his wife Sextilia, and had one brother, Lucius Vitellius the Younger. Suetonius recorded two different accounts of the origins of the Vitellia (gens), one making them descendants of past rulers of Latium, the other describing their origins as lowly.
The Gens Vitellia or Vitelii were a gens in ancient Rome. It is also spelled Vitullius in inscriptions.
In the time of Suetonius it was controversial between Aulus Vitellius (supporter of the princeps) and his enemies whether it was old and noble or recent and obscure, even plebeian. It would have originated as a diminutive of the cognomen Vitulus. The name of the Vitellii at least is old and their ancestry was said to date back to Faunus, king of the aboriginals, and Vitellia (Suetonius, Vitellius 1). Then, according to tradition, the family came from Sabini territory to Rome and were included among the patricians. As evidence for the existence of these early kings is the Via Vitellia from the Janiculum to the sea and a colonia Vitellia in Aequi territory.
Two brothers of Vitellii were among the chief supporters of Tarquinius Superbus's attempt to regain the throne; their sister was the wife of the consul Lucius Junius Brutus. On the other hand, Cassius Severus and others considered that the Vitellii were of low birth: the founder of the gens was, they argued, a freedman who had a son with a prostitute, and that son only joined the equites because of his accumulated wealth (Suet., Vitell.. 1-2). Suetonius leaves the question of the gens's origins unanswered. See also Vitelli-a 16th Century prominent family of Umbria who claimed relationship to the Vitellius {gens}
