The Supreme Order of the Most Holy Annunciation (Italian: Ordine Supremo della Santissima Annunziata) is a Roman Catholic order of chivalry, originating in Savoy. It eventually was the pinnacle of the honours system in the Kingdom of Italy, which ceased to be a national order when the kingdom became a republic in 1946. Today, the order continues as a dynastic order under the jurisdiction of the Head of the House of Savoy. Source: Wikipedia (en)
