This is a list of the heads of state of Italy. 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.
In 951 Otto I of Germany invaded Italy and was crowned with the Iron Crown of Lombardy. In 952, Berengar and Adalbert became his vassals but remained kings until being deposed by Otto.
Roger II used the title King of Sicily and Italy until at least 1135; later he used only the title King of Sicily, Apulia and Calabria. Although his realm included the southern Italian mainland, he never exerted any control over the official Kingdom of Italy, and none of his successors claimed the title King of Italy.
Charles V was the last emperor to be crowned king of Italy, or to officially use the title.[2] The Habsburg emperors claimed the Italian crown until 1801. The empire continued to include Italian territories until its dissolution in 1806.
After the constitutional referendum which took place at the same time as the general election 54.3% voted for a republic. The Constituent Assembly which had the power to rule Italy until a new constitution for the republic was drawn up. The provisional Head of State after Alcide De Gasperi who exercised the powers after the King of Italy left was Enrico De Nicola who was proclaimed in 1946 but he was called Temporary Chief of State because he did not want to be called President of the Republic until the constitution was law.
Under the Constitution, the first constitution of the Republic of Italy, the President replaced the monarch as ceremonial head of state. The President was elected by Parliament and Regional governments for a seven-year term. In the event of a vacancy the President of the Senate served as Acting President.
Parties
Traditionally, Presidents have not been members of any political party during their tenure, in order to be considered above partisan interests. The parties shown are those to which the President belonged at the time they took office.
