Pope Gregory II was the bishop of Rome from 19 May 715 to his death. His defiance of Emperor Leo III the Isaurian as a result of the iconoclastic controversy in the Eastern Empire prepared the way for a long series of revolts, schisms, and civil wars that eventually led to the establishment of the temporal power of the popes.

Pope Vigilius was the bishop of Rome from 29 March 537 to his death. He is considered the first pope of the Byzantine papacy. Born into Roman aristocracy, Vigilius served as a deacon and papal apocrisiarius in Constantinople. He allied with Empress Theodora, who sought his help to establish Monophysitism, and was made pope after the deposition of Silverius. After he refused to sign Emperor Justinian I's edict condemning the Three Chapters, Vigilius was arrested in 545 and taken to Constantinople. He died in Sicily while returning to Rome.
Pope Pelagius I was the bishop of Rome from 556 to his death. A former apocrisiarius to Constantinople, Pelagius I was elected pope as the candidate of Emperor Justinian I, a designation not well received in the Western Church. Before his papacy, he opposed Justinian's efforts to condemn the "Three Chapters" in order to reconcile theological factions within the Church, but later adopted Justinian's position.
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 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.
Alduin was king of the Lombards from 547 to 560.
Saint Cerbonius was a bishop of Populonia during the Barbarian invasions. Saint Gregory the Great praises him in Book XI of his Dialogues.
The Byzantine Papacy was a period of Byzantine domination of the Roman papacy from 537 to 752, when popes required the approval of the Byzantine Emperor for episcopal consecration, and many popes were chosen from the apocrisiarii or the inhabitants of Byzantine-ruled Greece, Syria, or Sicily. Justinian I reconquered the Italian peninsula in the Gothic War (535–554) and appointed the next three popes, a practice that would be continued by his successors and later be delegated to the Exarchate of Ravenna.
The Ostrogothic Papacy was a period from 493 to 537 where the papacy was strongly influenced by the Ostrogothic Kingdom, if the pope was not outright appointed by the Ostrogothic King. The selection and administration of popes during this period was strongly influenced by Theodoric the Great and his successors Athalaric and Theodahad. This period terminated with Justinian I's (re)conquest of Rome during the Gothic War (535–554), inaugurating the Byzantine Papacy (537–752).
Rufius Petronius Nicomachus Cethegus was a politician of Ostrogothic Italy and the Eastern Roman Empire. He was appointed consul for 504 AD, and held the post without a colleague. His father was Petronius Probinus, the consul for 489 and prominent supporter of Antipope Laurentius.
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.
