when was the red cross symbol first used
Emblems of the International Red Cross and Red Crescent Movement The Red Cross on white background was the original protection symbol declared at the 1864 Geneva Convention. The ideas to introduce a uniform and neutral protection symbol as well as its specific design originally came from Dr. Louis Appia, a Swiss surgeon, and Swiss General Henri Dufour, founding members of the International Committee.
Christian cross The earliest depiction of the Christian Cross may be the Herculaneum Cross which was found in the city of Herculaneum, which was entombed in pyroclastic material along with Pompeii during the eruption of Mount Vesuvius in AD 79. Another early depictions of the cross as a Christian symbol is the Alexamenos graffito.
