Justinian I (r. 527–565) Sergius came from a family in
Dara,
Mesopotamia. He was the middle son of the priest Bacchus, brother of the officers Cyrus and Solomon, and nephew of the famous general Solomon. He is first mentioned in 543 when he was appointed duke of
Tripolitania (
dux militis Tripolitanae provinciae) and raised to the rank of ; the sources state that he was still young at this time. He was visited in
Leptis Magna, the seat of Tripolitania, by the Moorish tribe of the Laguatan, who sought the usual payment and assurances of peace. On the advice of Pudentius, he allowed only 80 tribal leaders to enter the city, with a promise that he would do what they asked. A banquet was offered to the Moors, and in it, the Berber leaders were massacred. One of them, however, managed to escape and warned his people of what had happened. A battle was fought near Leptis Magna and the Moors were defeated. Many of them were killed, their women and children enslaved, and their camps looted. In 544, as the revolt was getting out of hand, Sergius set out for
Carthage to seek reinforcements from his uncle Solomon. He accompanied Solomon, and his brothers Cyrus and Solomon in their march against the tribal leader
Antalas. Sergius encamped with the others at
Tébessa and presumably participated in the Battle of Cilium, in which the Byzantines were defeated and his uncle perished; according to the sources, Sergius left his brother Solomon to die. in detail of a mosaic from the
Basilica of San Vitale According to
Procopius, his appointment as prefect of Africa was a disaster, as Sergius was more concerned about flaunting his money and power than actually managing the province. Furthermore, according to Procopius, during his tenure soldiers were alienated, among them officer John. Consequently, no measures were taken to stop the advance of the Moors commanded by Antalas, nor the rebels led by
Stotzas. In a letter to Justinian, Antalas stated that he would cease hostilities if Sergius was dismissed and another general was sent, but the emperor did not comply with the request. According to what the sources reveal, at this point, the African army was so small that Father Paul of
Hadrumetum was denied 80 men to recover his city. At the imperial court in
Constantinople, Sergius won the appreciation of
empress Theodora (r. 527–548), which freed him from any accusation of the mismanagement of Africa. In addition, he was one of the suitors of the granddaughter of
Antonina, the wife of
Belisarius. Later, probably in the fall of 547, he was sent together with the
Iberian prince Pacurius with an army to
Italy, in response to Belisarius' appeal.His activities in Italy were not recorded. He is last mentioned in 559 when he was a
patrician. This year, when the
Kutrigurs and
Slavs invaded
Thrace, Sergius was robbed and captured as a prisoner by
Zabergan. Later the same year, he was released on payment of ransom. == References ==
