King of Italy (Italian:Re d'Italia;Latin:Rex Italiae) was the title given to the ruler of theKingdom of Italy after the fall of theWestern Roman Empire. The first to take the title wasOdoacer, abarbarian warlord, in the late 5th century, followed by theOstrogothic kings up to the mid-6th century. With theFrankish conquest of Italy in the 8th century, theCarolingians assumed the title, which was maintained by subsequentHoly Roman Emperors throughout the Middle Ages. The last Emperor to claim the title wasCharles V in the 16th century. During this period, the holders of the title were crowned with theIron Crown ofLombardy.
In 568, theLombards entered the peninsula and ventured to recreate a barbarian kingdom in opposition to the Empire, establishing their authority over much of Italy, except theExarchate of Ravenna and the duchies ofRome,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 theFranks underCharlemagne, who deposed their king and took up the title "king of the Lombards". After the death ofCharles 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 titleRex Italicorum ("King of the Italians" or "King of the Italics") was introduced. After the breakup of the Frankish Empire,Otto I added Italy to theHoly Roman Empire and continued the use of the titleRex Italicorum. The last to use this title wasHenry II (1004–1024). Subsequent emperors used the title "King of Italy" untilCharles V. They were crowned inPavia,Milan andBologna.
Initially namedDux Italiae (Duke of Italy) by Zeno, the Roman Emperor inConstantinople, he later was recognized as King of Italy by thefoederati in control of the Italian peninsula. He was deposed by theOstrogoths, who established their own kingdom.
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 theRoman citizens in Italy as a viceroy of the Roman emperors, and their ownGothic 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 EmperorJustinian in 553.
Byzantine Roman authority in Italy was briefly re-established under Justinian, though his gains were lost under his successor Justin II, after a new Germanic tribe, theLombards, invaded from the north and established their kingdom in 568.
The Lombards under Alboin established their kingdom in the extreme north of Italy in 568, gradually pushing the Byzantine Romans back from the peninsula until only theExarchate of Ravenna remained under Roman control. This finally fell in the 750s, with the Lombards gaining control of most of the peninsula. The last Lombard King of Italy, Desiderius, was deposed by his son-in-law Charlemagne, who folded it into the largerCarolingian Empire, which evolved over time into theHoly Roman Empire.
Charlemagne ruled over northern Italy asKing of the Lombards. In 781, he named his son Pepin as King of Italy, though he still maintained suzerainty over the land. Charlemagne was crownedRoman Emperor in 800, while the Kingdom of Italy became one of the constituent kingdoms of the Empire. Beginning with Louis the Pious in 818, the Kingdom was ruled directly by the Carolingian Emperor himself.
In 951Otto I invaded Italy and was crowned with theIron Crown of Lombardy. In 952, Berengar and Adalbert became his vassals but remained kings until being deposed by Otto.
Otto is considered to be the founding emperor of theHoly Roman Empire, and the Kingdom of Italy was considered one of the constituent realms of the Empire. Beginning in the 12th century, states such as theRepublic of Venice and thePapal States captured more and more territory from the Kingdom of Italy, and the Empire's territory on the Peninsula shrunk over time. AfterCharles V, the emperors stopped being crowned with the Iron Crown of Lombardy and the Italian title fell into disuse. Imperial control in Italy receded toTrent and South Tyrol until thedissolution of the Empire in 1806. Southern Italy had never been part of the Holy Roman Empire; it remained initially under the control of various Byzantine fiefs until theNormanKingdom of Sicily (later theKingdom of Naples) took control of the area in the 11th century. Central Italy, along the Rome-Ravenna axis, was part of thePapal States, under the direct personal rule of the pope. TheDuke of Savoy wasde jure a vassal of the Holy Roman Emperor, with the Duke being Prince and Perpetual Vicar of the Holy Roman Empire.
Charles V was the last emperor to be crowned king of Italy or to officially use the title.[4] The Habsburg emperors claimed the Italian crown until 1801. The empire continued to include Italian territories until its dissolution in 1806.
In 1805,Napoleon established a client state in northern Italy, named the Kingdom of Italy. He established himself as King of Italy, in personal union with his role asEmperor of the French. This client state did not survive the end of the Napoleonic era; in its place, theCongress of Vienna established a number of independent duchies and kingdoms in the region.
During and after theRevolutions of 1848, sentiment on the peninsula grew for the establishment of a unified Italian kingdom. Southern Italy had not been united with northern Italy since the early medieval period, being mostly under the rule of theKingdom of Naples and theKingdom of the Two Sicilies. Northern Italy, in the early 19th century, came under the domination of theKingdom of Sardinia, which besides its namesake island, also ruled the expansivePiedmont andSavoy regions along the French-Italian borderlands. The formerly republican leader in southern Italy,Giuseppe Garibaldi, made common cause with theHouse of Savoy to overthrow the Kingdom of the Two Sicilies, and the people voted in a plebiscite to join Sardinia to form the Kingdom of Italy in 1861; the Papal States and the city of Rome were annexed to the Kingdom in 1870, completing theUnification of Italy. This kingdom lasted until the aftermath ofWorld War II, when the1946 Italian institutional referendum ended the monarchy.
