King of Italy (; ) was the title given to the ruler of the Kingdom of Italy after the fall of the Western Roman Empire. The first to take the title was Odoacer, a barbarian military leader, in the late 5th century, followed by the Ostrogothic kings up to the mid-6th century. With the Frankish conquest of Italy in the 8th century, the Carolingians assumed the title, which was maintained by subsequent Holy Roman Emperors throughout the Middle Ages. The last Emperor to claim the title was Charles V in the 16th century. During this period, the holders of the title were crowned with the Iron Crown of Lombardy.
A Kingdom of Italy was restored from 1805 to 1814 with Napoleon as its only king, centred in Northern Italy. It was not until the Italian unification in the 1860s that an independent Kingdom of Italy covering the entire Italian Peninsula was restored. From 1861 the House of Savoy held the title of King of Italy until the last king, Umberto II, was exiled in 1946 when Italy became a republic.
History
After the deposition of the last Western Emperor in 476, Heruli leader Odoacer was appointed Dux Italiae (Duke of Italy) by the reigning Byzantine Emperor Zeno. Later, the Germanic foederati, the Scirians and the Heruli, as well as a large segment of the Italic Roman army, proclaimed Odoacer ('King of Italy). In 493, the Ostrogothic king Theoderic the Great killed Odoacer, and set up a new dynasty of kings of Italy. Ostrogothic rule ended when Italy was reconquered by the Byzantine Empire in 552.
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, except the Exarchate of Ravenna and the duchies of Rome, Venetia, Naples and the southernmost portions. In the 8th century, estrangement between the Italians and the Byzantines 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 "king of the Lombards". After the death of Charles the Fat in 887, Italy fell into instability and a number of kings attempted to establish themselves as independent Italian monarchs. During this period, known as the Feudal Anarchy (888–962), the title Rex Italicorum ("King of the Italians" or "King of the Italics") was introduced. After the breakup of the Frankish empire, Otto I added Italy to the Holy Roman Empire and continued the use of the title Rex Italicorum. The last to use this title was Henry II (1004–1024). Subsequent emperors used the title "King of Italy" until Charles V. They were crowned in Pavia, Milan and Bologna.
In 1805, Napoleon I was crowned with the Iron Crown of Lombardy at the Milan Cathedral. The next year, Holy Roman Emperor Francis II abdicated his imperial title. From the deposition of Napoleon I (1814) until the Italian Unification (1861), there was no Italian monarch claiming the overarching title. The Risorgimento successfully established the House of Savoy dynasty over the whole peninsula and, uniting the kingdoms of Sardinia and the Two Sicilies, it formed the modern Kingdom of Italy. The monarchy was superseded by the Italian Republic, after a constitutional referendum was held on 2 June 1946, after World War II. The Italian monarchy formally ended on 12 June of that year and Umberto II left the country.
As "Kingdom of Odoacer"
Initially named Dux Italiae (Duke of Italy) by Zeno, the Roman Emperor in Constantinople, he later was recognized as King of Italy by the Foederati in control of the Italian peninsula. He was deposed by the Ostrogoths, who established their own kingdom.
Odoacer (476–493)
Ostrogothic Kingdom (493–553)
Theodoric the Great was invited by the emperor Zeno to take Italy from Odoacer and rule it in Zeno's name. He defeated Odoacer in 493, establishing a new kingdom in place of Odoacer's. Officially, the Ostrogothic kings ruled the Roman citizens in Italy as a viceroy of the Roman emperors, and their own Gothic people as their king, though functionally they ran their kingdom entirely independently from the Roman authority in Constantinople. Their greatest extent was during Theodoric's reign; as Roman Emperors from the east began to exert more power and retake control of Roman territory, the last Ostrogothic king fell to the Emperor Justinian in 553.
