The Turkish War Medal of 1915. This medal is referred to by a number of informal names. Commonwealth nations often call it the "Gallipoli Star" even though it was not a campaign medal specifically for that battle. Another informal name is the "Iron Crescent," as it functioned similarly to Prussia's Iron Cross. The medal was given from 1915 until the end of the war, for acts of bravery or merit in action. Recipients of the Imtiaz and Liyakat medal were automatically eligible for this medal. The medal is a star-shaped pin back badge of white metal (not iron), with a raised crescent around the bottom center, and the "Toughra" or monogram of the Sultan in the center. The flat surfaces of the badge were finished in a thin opaque red enamel. The War Medal was worn pinned to the tunic in a manner similar to the Iron Cross, and not suspended from a ribbon. There was a ribbon (red with white side stripes) which was worn in the second button hole (like the Iron Cross 2nd Class) when the star itself was not worn.
Because the medal was frequently awarded to German and Austrian personnel who served with the Turkish forces during WW1, many unofficial variants were made in Germany and elsewhere, of varying quality, but usually of higher quality than the originals. This difference in quality had led some early authors to speculate that there were two classes of the War Medal -- poor quality copies for enlisted men, nicer copies for officers. In fact there was only one class.
