What year did Napoleon become King of Italy?

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.

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 a dynasty, the House of Savoy, over the whole peninsula, uniting the kingdoms of Sardinia and the Two Sicilies to form the modern Kingdom of Italy.

Although Napoleon I used the title from 1805 to 1814, it was not until the Unification of Italy in the 1860's that a Kingdom of Italy was restored. From 1861 the House of Savoy held the title as monarchs of the entire peninsula until the last King of Italy, Umberto II, abdicated in 1946 when Italy became a republic.
