"Il Canto degli Italiani" officially became the national anthem of Italy, 66 years after it was provisionally chosen following the birth of the Italian Republic.

"Il Canto degli Italiani" is a patriotic song written by Goffredo Mameli and set to music by Michele Novaro in 1847, currently used as the national anthem of Italy. It is best known among Italians as the "Inno di Mameli", after the author of the lyrics, or "Fratelli d'Italia", from its opening line. The piece, in ⁴
₄ time signature and B-flat major key, has six strophes, and a refrain sung after each. The sixth group of verses, almost never performed, recalls the first strophe's text.

A national anthem is a patriotic musical composition symbolizing and evoking eulogies of the history and traditions of a country or nation. The majority of national anthems are marches or hymns in style. American, Central Asian, and European nations tend towards more ornate and operatic pieces, while those in the Middle East, Oceania, Africa, and the Caribbean use a more simplistic fanfare. Some countries that are devolved into multiple constituent states have their own official musical compositions for them ; their constituencies' songs are sometimes referred to as national anthems even though they are not sovereign states.

An institutional referendum was held by universal suffrage in the Kingdom of Italy on 2 June 1946, a key event of contemporary Italian history. Until 1946, Italy was a kingdom ruled by the House of Savoy, reigning since the unification of Italy in 1861 and previously rulers of the Kingdom of Sardinia. In 1922, the rise of Benito Mussolini and the creation of the Fascist regime in Italy, which eventually resulted in engaging the country in World War II alongside Nazi Germany, considerably weakened the role of the royal house.
