Vitiges was king of Ostrogothic Italy from 536 to 540. He succeeded to the throne of Italy in the early stages of the Gothic War of 535–554, as Belisarius had quickly captured Sicily the previous year and was in southern Italy at the head of the forces of Justinian I, the Eastern Roman Emperor.
The Gothic War between the Eastern Roman Empire during the reign of Emperor Justinian I and the Ostrogothic Kingdom of Italy took place from 535 to 554 in the Italian Peninsula, Dalmatia, Sardinia, Sicily and Corsica. It was one of the last of the many Gothic Wars against the Roman Empire. The war had its roots in the ambition of the Eastern Roman (Byzantine) 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, during the Migration Period.
Hermogenes was an East Roman (Byzantine) official who served as magister officiorum, military commander and diplomatic envoy during the Iberian War against Sassanid Persia in the early reign of Emperor Justinian I.
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.
