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).
Grand Duchy of Tuscany The Grand Duchy of Tuscany (Italian: "Granducato di Toscana" , Latin: "Magnus Ducatus Etruriae" ) was a central Italian monarchy that existed, with interruptions, from 1569 to 1859, replacing the Duchy of Florence. The grand duchy's capital was Florence. Tuscany was nominally a state of the Holy Roman Empire until the Treaty of Campo Formio in 1797.
