The Kingdom of Italy (Italian: Regno d'Italia; Latin: Regnum Italiae) is a large, northern Italian member state of the Holy Roman Empire. Founded in its current form as a united entity in 1440 from the Duchy of Milan, the Kingdom originating in 773 with Charlemagne conquering the Kingdom of the Lombards. It was then held as a title of the Holy Roman Emperor until Wenceslaus V gave it to Niccolò Maria Visconti, who is the current ruler of Italy.

In addition to the Kingdom of Italy, King Niccolò Maria is also, by jure uxoris, the King of Naples due to his marriage with Queen Mary I Anjou.
