The Gallipolli Star is a military decoration awarded by the Ottoman Empire. It was known as the Ottoman War Medal (Turkish: Harp Madalyası) or the Iron Crescent (from German Eiserner Halbmond, in allusion to the Iron Cross). It was instituted by Sultan Mehmed V on 1 March 1915 for gallantry in battle. This decoration was awarded for the duration of World War I to Ottoman and other Central Powers troops, primarily in Ottoman areas of engagement. Source: Wikipedia (en)
