Suetonius gives two possible birthdays for Aulus Vitellius: September 24 or September 7 in the year 15 CE. The uncertainty is part of the evidence. What followed is clearer: more than five decades later, the Roman governor sent to command the Rhine legions became the third emperor of the convulsive Year of the Four Emperors.

A birthday preserved with a warning
In his biography of Vitellius, Suetonius writes that the future emperor was born on the eighth day before the Kalends of October—September 24 by Roman inclusive counting—or, according to some authorities, on the seventh day before the Ides of September, September 7. He places the birth in the consulship of Drusus Caesar and Norbanus Flaccus, which fixes the year as 15 CE.
This is not a modern database discrepancy. It is an ancient author openly preserving conflicting information. Roman biographers drew on records, family traditions, gossip and earlier histories, and they did not always conceal disagreement. The responsible way to mark September 24 is therefore to say that it is Suetonius’s first date, not the only date transmitted in antiquity.
Suetonius adds an ominous story: astrologers supposedly frightened Vitellius’s parents with predictions about the child’s future. Such anecdotes served the literary architecture of imperial biography. They made a later rise and fall seem foreshadowed from birth. They should be read as part of how Romans explained character and destiny, not as independently verified scenes from a nursery.
Born into imperial connections
Vitellius belonged to a prominent family. His father, Lucius Vitellius, held the consulship three times, governed Syria and enjoyed the confidence of Emperor Claudius. The younger Vitellius grew up near the center of power and learned how advancement depended on access to the ruler and the court.
Later hostile writers depicted him as a creature of appetite and flattery. Suetonius associated his youth with the court of Tiberius on Capri and claimed that he won favor under Caligula through chariot racing, under Claudius through dice and under Nero through support for the emperor’s performances. Tacitus, Suetonius and Cassius Dio all wrote with knowledge of Vitellius’s defeat and death. Their portraits are essential, but they are also shaped by senatorial values, moral judgment and the propaganda of the Flavian victors.
His career was not simply farce. Vitellius held major priesthoods, a consulship, the proconsulship of Africa and administrative office in Rome. Suetonius even says his conduct in Africa was distinguished by integrity. The record suggests an aristocrat capable of conventional service as well as courtly survival.
The Rhine legions choose an emperor
Nero’s death in June 68 ended the Julio-Claudian dynasty and revealed that imperial power could be made outside Rome. Galba became emperor, but his austerity and political errors alienated soldiers and elites. Late in 68, Galba appointed Vitellius to command the army of Lower Germany. Ancient writers imply that Galba selected a man he considered harmless. If so, the judgment failed spectacularly.
On January 2, 69, troops in Lower Germany acclaimed Vitellius emperor; forces in Upper Germany joined them. Commanders Aulus Caecina Alienus and Fabius Valens led armies toward Italy. Meanwhile Galba was killed in Rome and Otho took power. Vitellian and Othonian forces met in northern Italy. After defeat at the First Battle of Bedriacum in April, Otho killed himself to prevent further civil war.
Vitellius entered Rome as emperor, the third man to hold the position within a year. His authority rested on victory and the loyalty of armies far from the capital—the same political fact that would soon destroy him.
Rule under the shadow of civil war
Accounts of Vitellius’s reign emphasize feasting, extravagance and indiscipline. Suetonius’s catalogue of banquets helped create the emperor’s lasting reputation as a glutton. Modern historians treat the exact figures and lurid details cautiously. Roman political biography often converted public failure into private vice.
There were concrete problems. Rewarding the German legions and managing rival military groups strained authority. Officers and soldiers expected payment and recognition. In the east, armies supporting the general Vespasian presented a new challenge. On July 1, 69, troops in Egypt proclaimed Vespasian emperor; other eastern legions followed.
Vespasian remained in the eastern Mediterranean while allied commanders moved into Italy. Vitellian forces lost the Second Battle of Bedriacum in October. Flavian troops advanced on Rome. Negotiations and attempted abdication broke down amid factional violence, including fighting on the Capitoline Hill and the burning of the Temple of Jupiter Optimus Maximus.
The emperor’s death
In December, Flavian forces entered Rome. Vitellius was discovered, dragged through the streets and killed. Ancient narratives dwell on humiliation because a degraded death completed their moral portrait. Vespasian’s victory founded the Flavian dynasty and restored a measure of stability after a year in which Galba, Otho, Vitellius and Vespasian had each been proclaimed emperor.
Vitellius’s brief reign exposed a structural truth of the principate. Augustus had cloaked one-man rule in republican forms, but succession still depended on family, elite acceptance and military force. When dynastic continuity failed, provincial armies could nominate their own candidates and march on the capital.
Why a disputed birthday matters
September 24 offers more than an anniversary. It shows how historical knowledge is built. The date comes from a named ancient source that also records an alternative. The same source mixes offices, family information, rumor, moral anecdote and dramatic foreshadowing. Reading it well means neither dismissing it nor repeating every detail uncritically.
Vitellius is remembered as a caricature because the winners of 69 CE shaped the literary record. Behind that caricature was a senator whose conventional career placed him in command of a powerful army at the moment Rome’s succession system fractured. His rise was improbable; the conditions that made it possible were fundamental to the empire.

Sources and method
The birth-date evidence comes from Suetonius, Vitellius 3. The political narrative is checked against Tacitus’s Histories and modern scholarship on 69 CE. Hostile ancient character judgments are identified as claims rather than converted into undocumented fact.
