Year of the Four Emperors

TheYear of the Four Emperorswas a year in the history of theRoman Empire,AD 69, in which four emperors ruled in a remarkable turnover. The four emperors wereGalba,Otho,Vitellius,andVespasian.

The suicide of emperorNero,in 68, was followed by a brief period of civil war, the firstRoman civil warsinceMark Antony's death in 30 BC. Between June of 68 and December of 69,Romewitnessed the successive rise and fall of Galba, Otho and Vitellius until the finalaccessionof Vespasian, the first ruler of theFlavian Dynasty.

This was an example of the political disturbances which occurred in the history of theRoman Empire.The military and political anarchy created by this civil war had serious repercussions, such as the outbreak of theBatavian rebellion.TheJewish Revoltwas already ongoing.

The succession

Nero to Galba

By June of 68, the Senate took the initiative to rid itself of Nero, declaring him a public enemy and Galba emperor. ThePraetorian Guardwere bribed to betray Nero, and Nero committed suicide. Galba was recognized as emperor and welcomed into the city at the head of hislegions.

Galba did not remain popular for long. On his march to Rome, he either destroyed or took enormous fines from towns that did not accept him immediately. In Rome, Galba cancelled all the reforms of Nero, including benefits for many important persons. The army was not happy either. After his safe arrival in Rome, Galba refused to pay the rewards he had promised to soldiers who had supported him. The Romantreasurywas indeed in a bad way after Nero'sextravagances,but Galba did not handle the situation well.

Like Nero, Galba had a fear of conspirators andexecutedmany senators andequiteswithout trial. Moreover, in the start of the civil year of 69 on January 1, the legions of Germania Inferior refused to swear allegiance and obedience to the new emperor. On the following day, the legions acclaimed Vitellius, their governor, as emperor.

Marcus Salvius Othobribed thePraetorian Guard,already very unhappy with the emperor, to his side. When Galba heard about thecoup d'étathe went to the streets in an attempt to normalize the situation. It proved a mistake, because he could attract no supporters. Shortly afterwards, the Praetorian Guard killed him in theForum.

Otho to Vitellius

Otho was recognized as emperor by the Senate that same day. The new emperor was saluted with relief. Although ambitious and greedy, Otho did not have a record for tyranny or cruelty and was expected to be a fair emperor. However, trouble in the form of Vitellius was marching down on Italy from Germany.

Vitellius had behind him the finest elite legions of the empire, composed of veterans of theGermanic Wars.These would prove to be his best arguments to gain power. Otho was not keen to begin another civil war and sent emissaries to propose a peace and inviting Vitellius to be his son-in-law. It was too late to reason; Vitellius' generals had half of his army heading to Italy. After a series of minor victories, Otho was defeated in theBattle of Bedriacum.Rather than flee and attempt a counter-attack, Otho decided to put an end to the anarchy and committed suicide. He had been emperor for a little more than three months.

Vitellius to Vespasian

On the news of Otho's suicide, Vitellius was recognised as emperor by the Senate. Given this recognition, Vitellius set out for Rome. He faced problems from the start of his reign. The city was left very skeptical when Vitellius chose a day of bad auspices (according to Roman superstition) to accept the office ofPontifex Maximus.

Events would seemingly prove them right. With the throne tightly secured, Vitellius engaged in a series offeasts,banquetsand triumphalparadesthat drove the imperialtreasuryclose tobankruptcy.Debts were quickly accrued and money-lenders started to demand repayment.

Vitellius showed his violent nature by ordering the torture and execution of those who dared to make such demands. Vitellius took the step of killing citizens who named him as theirheir,often together with any co-heirs. Moreover, he engaged in a pursuit of every possible rival, inviting them to the palace with promises of power only to have themassassinated.

Vespasian had been given a special command inJudaeaby Nero in 67 with the task of putting down theGreat Jewish Revolt.He gained the support of the governor of Syria,Gaius Licinius Mucianus.A strong force drawn from the Judaean and Syrian legions marched on Rome under the command of Mucianus. Vespasian himself travelled toAlexandriawhere he had been acclaimed Emperor on July 1, thereby gaining control of the vitalgrainsupplies from Egypt. Vespasian's sonTitusremained in Judaea to deal with the Jewish rebellion. Before the eastern legions could reach Rome, theDanubianlegions of the provinces of Raetia and Moesia also acclaimed Vespasian as Emperor in August, and led byMarcus Antonius Primusinvaded Italy. In October, the forces led by Primus won a crushing victory over Vitellius' army at the SecondBattle of Bedriacum.

Surrounded by enemies, Vitellius made a last attempt to win the city to his side, distributing bribes and promises of power where needed. The Danube army was now very near Rome. Vitellius went into hiding and prepared to flee, but decided on a last visit to the palace. There he was caught by Vespasian's men and killed. In seizing the capital, they burned down thetempleofJupiter.

The Senate acknowledged Vespasian as emperor on the following day. It was 21 December 69, the year that had begun with Galba on the throne.
