The third of the emperors to rule during the tumultuous Year of the Four Emperors, Vitellius first started his career as Consul in 48 CE, and was eventually given command of the armies of Germania Inferior by Emperor Galb. From there he began his bid for power against Galba and the other claimants.

He successfully led a military revolution against Galba's successor Otho in 69 CE, marching into Rome and becoming Emperor, though he was never acknowledged as such in the entire Roman world. His men were said to be licentius and rough, with Rome becoming embroiled in massacres and riots, decadent feasts and gladiatorial shows. Vitellius himself was described as lazy and self-indulgent, an obese glutton and a hedonist.

In July 69 CE, Vitellius learned that the eastern provinces had declared a rival emperor, Commander Vespasian. Following more provinces declaring for Vespasian and mass desertions among his own adherents, Vitellius resigned as emperor in December 69 CE. He was executed by Vespasian's men upon their arrival to Rome. His reign lasted 8 months.
