King of Italy (
rex Italiae in
Latin and
re d'Italia in Italian) is a title adopted by many rulers of the
Italian peninsula after the fall of the
Roman Empire. However, no “King of Italy” ruled the whole peninsula until
Victor Emmanuel in 1870, though some pretended to such authority.
After the deposition of
Western Roman Emperor Romulus Augustulus in 476,
Heruli leader
Odoacer was appointed
dux Italiae (Duke of Italy) by the reigning
Eastern Roman Emperor Zeno. Later, he took the title of
rex (not, as is sometimes said,
rex italiae), though he always presented himself as an officer of the eastern government. In 493,
Ostrogothic king
Theodoric the Great defeated Odoacer, and set up
a new dynasty of kings of Italy. Ostrogothic rule ended when Italy was reconquered by the
Byzantine Empire in 552.
This state of affairs did not last long. In 568, the
Lombards entered the peninsula and ventured to recreate a barbarian kingdom
in opposition to the Empire, establishing their authority over much of Italy (especially
Lombardy) except the
Exarchate of Ravenna and the duchies
Rome,
Venetia,
Naples and the southernmost portions. For the next two centuries, Lombards and Byzantines fought for dominance in the peninsula.
In the 8th century, estrangement between the Italian Romans and the Byzantine Empire allowed the Lombards to capture the remaining Roman enclaves in northern Italy. However, in 774, they were defeated by the
Franks under
Charlemagne, who deposed their king and took up the title
rex Langobardorum ("King of the Lombards"). Within the
Frankish Empire, Italy was ruled by a
rex Italiae. This Kingdom of Italy was integrated into the
Holy Roman Empire by
Otto I. All subsequent emperors used the title and most were crowned at some time in the ancient Lombard capital of
Pavia before their imperial coronation in Rome. However the various emperors ruled only parts of Italy, and many independent states existed on the peninsula over the subsequent centuries, some of which were kingdoms, such as the
Kingdom of Sicily and the
Kingdom of Naples.
By the
Peace of Westphalia in 1648 most of the Italian territories of the
Holy Roman Empire were lost to it and the Italian Crown held no significance thereafter, either
de facto or
de jure. In 1805,
Napoleon Bonaparte endeavoured to attach the Lombard heritage to France again and was crowned with the
Iron Crown of Lombardy in Pavia. The next year, the
Emperor Francis II abdicated his Imperial title. From the deposition of Napoleon (1814) until the
Italian Unification (1861), there was no Italian monarch claiming the overarching title. The
Risorgimento successfully established a dynasty, the
House of Savoy, over the whole peninsula, uniting the kingdoms of
Sardinia and the
Two Sicilies. The monarchy was superseded by the
Italian Republic () after a referendum was held in 1946.

Ferdinand I and his successor used the title of a
King of Italy, though they were never crowned as such:
The
Peace of Westphalia effectively terminated any imperial claims to an Italian kingdom.
