511
Revolt of Vitalian

Vitalian (Flavius Vitalianus) is first mentioned in 503, when he accompanied his father in the Anastasian War against the Persians (see posting Sack of Amida). By 511, he had risen to the rank of comes in Thrace.

In 511, Emperor Anastasius changed the form of the Trisagion prayer and officially adopted the Monophysite dogma, angering the Empire's Chalcedonian population, adding to the disaffection caused by his strict financial policies. Furthermore, Anastasius had refused to supply the provisions due to the foederati (barbarian auxiliary troops), allowing Vitalian to quickly gain the allegiance of the regular troops stationed in the provinces of Thrace, Moesia II, and Scythia Minor from the unpopular magister militum per Thracias, Anastasius’ nephew Hypatius. Hypatius’ subordinate commanders were either killed or joined the rebellion. At the same time, posing as a champion of Chalcedonian orthodoxy, Vitalian was able to gain the support of the locals, who flocked to join his force. According to contemporary historians, he quickly assembled an army of 50-60,000 men and marched on Constantinople, possibly hoping that the mostly Chalcedonian inhabitants would join him. Indeed, it appears that Vitalian’s revolt was primarily motivated by religious reasons, something suggested by his repeatedly demonstrated willingness to reach an accommodation with Anastasius. To counter Vitalian’s propaganda, Anastasius ordered bronze crosses to be set up on the city walls inscribed with his own version of events. The emperor also reduced taxes in the provinces of Bithynia and Asia to prevent them from joining the rebellion.

When Vitalian's forces reached the capital, they encamped at the suburb of Hebdomon and blockaded the landward side of the city. Anastasius opted for negotiations, and sent out Vitalian’s former patron, the former consul and magister militum praesentalis Patricius. Vitalian declared his aims: the restoration of Chalcedonian orthodoxy and the settling of the Thracian army’s grievances. Patricius then invited him and his officers into the city itself for negotiations. Vitalian refused for himself, but allowed his senior officers to go the next day. The officers were well treated by Anastasius, who gave them gifts and promised that their soldiers’ grievances would be settled. He also pledged to submit the religious dispute for resolution to the Patriarch of Rome. Upon their return to the rebel camp, these officers unanimously pressured Vitalian to accept this settlement. Faced with no alternative, only 8 days after his arrival before the capital, Vitalian returned with his men to Lower Moesia.

Anastasius then appointed as magister militum per Thracias an officer called Cyril, who proceeded to attack Vitalian. After a few inconclusive skirmishes, Vitalian managed to bribe his army's entry into Odessus, Cyril’s base, at night. Cyril was captured at his residence and killed. At this point, Anastasius had Vitalian declared a public enemy and sent out a new huge army, reportedly 80,000 men, under Hypatius, with a Hun called Alathar as the new magister militum of Thrace. After winning a minor initial victory, the imperial army was eventually pushed back towards Odessus (autumn 513). At Acris, on the Black Sea coast, Vitalian’s men attacked their fortified laager in darkness and dealt them a crushing defeat: the larger part of the imperial army was killed, and both its commanders were captured and held for ransom.

The victory consolidated Vitalian’s position. With the spoils, he was able to lavishly reward his followers, and at the news of the imperial army’s annihilation, the remaining cities and forts in Lower Moesia and Scythia surrendered to him. Soon after, he had another stroke of luck: at Sozopolis, his men captured an embassy sent by Anastasius to ransom Hypatius, including the ransom money of 1100 pounds of gold. Hypatius, whom Vitalian hated because he had once insulted his wife, was not released until a year later. In 514, Vitalian marched again towards Constantinople, this time gathering, in addition to his army, a fleet of 200 vessels from the Black Sea ports, which sailed down the Bosporus menacing the city from the sea as well. Anastasius was further disquieted by riots in the city, which left many casualties, and resolved to once again negotiate. Vitalian accepted, on the conditions of his nomination to the post of magister militum per Thracias and the receipt of ransom money and gifts worth 5000 pounds of gold for the release of Hypatius. Anastasius also conceded the removal of the changes from the Trisagion, the restoration of the deposed Chalcedonian bishops, and the convocation of a general church council at Constantinople in July 515.

The council never materialized, since Pope Hormisdas and Anastasius continued to be at loggerheads over the Acacian Schism. Neither were the deposed bishops returned to their sees. Seeing Anastasius failing to honor his promises, in late 515 Vitalian mobilized his army and marched again towards Constantinople. His army captured the suburb of Sycae (modern Galata) across the Golden Horn from the city and encamped there. The 2 magistri militum praesentalis, Patricius and John, were unwilling to engage their old friend Vitalian, thus Anastasius gave command of his forces to the former praetorian prefect of the East, Marinus, a trusted and influential aide. Despite his lack of military experience, Marinus defeated the rebel fleet in a battle at the entrance of the Golden Horn; according to the report of John Malalas, this was achieved through the use of a sulphur-based chemical substance invented by the philosopher Proclus of Athens, similar to the later Greek fire. Marinus then landed with his men on the shore of Sycae and defeated the rebels he found there. Disheartened, Vitalian and his army fled north under cover of night.

Once back in northern Thrace, Vitalian went into hiding, while many of his erstwhile aides were captured and executed. Nothing is known of him for the next 3 years, although a short remark by a chronicler seems to indicate that he resurfaced and led another armed rebellion during the last months of Anastasius’ life. When Anastasius died in July 518, he was succeeded by Justin I, the comes excubitorum (commander of the imperial bodyguard). The new emperor quickly moved to strengthen his rule, dismissing a number of potential rivals or enemies. At the same time, he called upon Vitalian to come to Constantinople.

Upon his arrival, Vitalian was made magister militum in praesenti, named honorary consul, and soon after raised to the rank of patrician. As a well-known champion of Chalcedonian orthodoxy, he was to play a role in the new regime’s reaffirmation of the Chalcedonian doctrines and reconciliation with Rome. He played an active role in the negotiations with the Pope, and in 519, he was one of the prominent men who escorted a papal delegation into the capital. Vitalian also took vengeance on the staunchly Monophysite Patriarch of Antioch, Severus, who had celebrated Vitalian’s defeat in a panegyric: Justin ordered Severus’ tongue to be cut, and Severus fled to Egypt along with Julian, Bishop of Halicarnassus.

Finally in 520, Vitalian was appointed ordinary consul for the year. Nevertheless, the former rebel continued to pose a potential challenge to Justin, and more importantly to his nephew and heir-apparent, Justinian. Thus, in July of the same year he was murdered inside the Great Palace along with his secretary Paulus and his domesticus (aide) Celerianus. According to John of Nikiou, he was killed because he was plotting against Justin; most chroniclers, however, put the responsibility for the crime on Justinian’s desire to rid himself of a potential rival for the succession.
