Red Cross on a white background, is the Emblem of Red Cross, recognized in 1864 as the distinctive sign for medical relief teams on the battle field.
In the Russo-Turkish war the Ottoman empire used a Red Crescent in place of the Red Cross. Egypt too opted for the Red Crescent while Persia chose a Red Lion on a white background. These symbols were written and accepted into the 1929 Geneva Conventions. The IRCS adopted RED CROSS as its emblem.
The National Society make use of the emblem as an indicative device in peacetime and during armed conflicts within the limits stipulated in national legislation, the regulations and its statutes only for activities consistent with the principles set out by International Federation of the Red Cross and Red Crescent.
During the General Assembly and the council of Delegates in November 2005 at Geneva, Red Crystal has been adopted as another emblem for the Red Cross Red Crescent movement.
