The titles of the Count of Savoy, and then Duke of Savoy, are titles of nobility attached to the historical territory of Savoy. Since its creation, in the 11th century, the House of Savoy held the county. Several of these rulers ruled as kings at one point in history or another.
The County of Savoy was elevated to a duchy at the beginning of the 15th century, bringing together all the territories of the Savoyard state and having Amadeus VIII as its first duke.[1] In the 18th century, Duke Victor Amadeus II annexed the Kingdom of Sardinia to the historical possessions of the Duchy, and from then on, the Savoyard dukes also held the title of Kings of Sardinia. The House of Savoy later went on to rule the Kingdom of Italy from 1861 to 1946 when the monarchy was abolished.
After the death of Umberto II in 1983, Prince Vittorio Emanuele succeeded him. On 7 July 2006, Amadeo claimed that Vittorio Emanuel had lost his royal rights when he married without Umberto II's permission in 1971, in which Amadeo declared himself the Head of the Royal House on the same day.
