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 Germany The Kingdom of Germany or German Kingdom (Latin: "Regnum Teutonicum" , "Teutonic Kingdom"; German: "Deutsches Reich" ) developed out of the eastern half of the former Carolingian Empire. Like Anglo-Saxon England and medieval France, it began as "a conglomerate, an assemblage of a number of once separate and independent... "gentes" [peoples] and "regna" [kingdoms]." East Francia ("Ostfrankenreich") was formed by the Treaty of Verdun in 843, and was ruled by the Carolingian dynasty until 911, after which the kingship was elective. The initial electors were the rulers of the stem duchies, who generally chose one of their own. After 962, when Otto I was crowned emperor, the kingdom formed the bulk of the Holy Roman Empire, which also included Italy (after 951), Bohemia (after 1004) and Burgundy (after 1032).
