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).
Kingdom of Italy (Holy Roman Empire) The Kingdom of Italy (Latin: "Regnum Italiae" or "Regnum Italicum", Italian: "Regno d'Italia") was one of the constituent kingdoms of the Holy Roman Empire, along with the kingdoms of Germany, Bohemia, and Burgundy. It comprised northern and central Italy, but excluded the Republic of Venice. Its original capital was Pavia until the 11th century.
