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 Byzantine 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 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.
The Byzantine Empire underwent a golden age under the Justinian dynasty, beginning in 518 AD with the accession of Justin I. Under the Justinian dynasty, particularly the reign of Justinian I, the empire reached its greatest territorial extent since the fall of its Western counterpart, 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 the Ostrogothic army. Many of Rome's male inhabitants were killed in the city or while attempting to flee—further reducing Rome's population which had collapsed in recent decades.
Bessas was an Eastern Roman 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.
