Italy (civil ensign), since 1947
Though it may look like a coat of arms, the shield on Italy’s civil ensign is not actually the national emblem. Instead it’s a quartering of the arms of the four great maritime republics of Italian history: Venice, Genoa, Amalfi, and Pisa. The flag of the Italian Navy has the same shield topped by a naval crown.
