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).
Council of Aragon The Council of Aragon, officially, the Royal and Supreme Council of Aragon (Spanish: Real y Supremo Consejo de Aragón; Catalan: Consell Suprem d'Aragó) was a ruling body and key part of the domestic government of the Spanish Empire in Europe, second only to the monarch himself. It administered the Crown of Aragon, which was composed of the Kingdom of Aragon, Principality of Catalonia (including Roussillon until 1659), Kingdom of Valencia, Kingdom of Mallorca, as well as Aragon's Italian possessions (Kingdom of Sicily, Naples, and Sardinia) until the 1558 creation of the Council of Italia. The Council of Aragon ruled these territories as a part of Spain, and later the Iberian Union.
