What is considered the Kingdom of Italy established from 493 to 553?
Ostrogothic Papacy 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).
Duchy of Perugia The Duchy of Perugia was a duchy (Latin: "ducatus") in the Italian part of the Byzantine Empire. Its civil and military administration was overseen by a duke ("dux") appointed by and under the authority originally of the Praetorian Prefect of Italy (554–584) and later of the Exarch of Ravenna (584–751). Its chief city and namesake was Perugia ("Perusia"), located at its centre. It was a band of territory connecting the Duchy of the Pentapolis to its northeast with the Duchy of Rome to its southwest, and separating the duchies of Tuscia (to its northwest) and Spoleto (to its southeast), both parts of the Lombard Kingdom of Italy. It was of great strategic significance to the Byzantines since it provided communication between Rome, the city of the Popes, and Ravenna, the capital of the Exarchate. Since it cut off the Duke of Spoleto from his nominal overlord, the king ruling from Pavia, it also disturbed the Lombard kingdom, which was a constant thorn in the Byzantines' side. This strategic importance meant that many Lombard and Byzantine armies passed through it.
