Totila, original name Baduila, was the penultimate King of the Ostrogoths, reigning from 541 to 552 AD. A skilled military and political leader, Totila reversed the tide of the Gothic War, recovering by 543 almost all the territories in Italy that the Eastern Roman Empire had captured from his Kingdom in 540.
The Gothic War between the East Roman (Byzantine) Empire during the reign of Emperor Justinian I and the Ostrogothic Kingdom of Italy took place from 535 until 554 in the Italian peninsula, Dalmatia, Sardinia, Sicily and Corsica. It was one of the last of the many Gothic Wars with the Roman Empire. The war had its roots in the ambition of the East Roman Emperor Justinian I to recover the provinces of the former Western Roman Empire, which the Romans had lost to invading barbarian tribes in the previous century.
The Byzantine Empire had its first golden age under the Justinian Dynasty, which began in 518 AD with the Accession of Justin I. Under the Justinian Dynasty, particularly the reign of Justinian I, the Empire reached its largest territorial point, reincorporating North Africa, southern Illyria, southern Spain, and Italy into the Empire. The Justinian Dynasty ended in 602 with the deposition of Maurice and the ascension of his successor, Phocas.
The city of Rome was besieged in AD 549–550 by the Ostrogoths, led by Totila, during a campaign to recapture Italy from the Byzantine Empire. After Totila imposed a blockade, soldiers from the city's garrison opened the gates to him. Many of the male inhabitants were killed in the city or while attempting to flee. The city was afterwards repopulated and rebuilt.
John, the nephew of the rebel Vitalian, was an East Roman (Byzantine) general under Justinian I, who was active in the Gothic War in Italy and against the Gepids in the western Balkans. He was married to Justina, the daughter of Justinian's cousin Germanus.
Bessas was an East Roman (Byzantine) general of Gothic origin from Thrace, primarily known for his career in the wars of Justinian I. He distinguished himself against the Sassanid Persians in the Iberian War and under the command of Belisarius in the Gothic War, but after Belisarius' departure from Italy he failed to confront the resurgent Goths and was largely responsible for the loss of Rome in 546. Returning east in disgrace, despite his advanced age he was appointed as commander in the Lazic War. There he redeemed himself with the recapture of Petra, but his subsequent idleness led Justinian to dismiss him and exile him to Abasgia.
The Siege of Ravenna of 539-540 took place during Justinian’s Gothic War. After clearing out Ariminum, Urviventus, Urbinus and Auximus the road to Ravenna was open to the Byzantines. In late 539 or early 540 Belisarius, victor of engagements like Dara, Ad Decimum and Rome, marched on Ravenna while Vitalius was already in the area. Vitalius discovered a grain shipment destined for Ravenna and captured it. When news of the siege spread many Gothic garrisons began to surrender. The city itself was taken when Belisarius was offered the Ostrogothic throne and faked acceptance.
