The flag of the Red Cross has a red Greek cross on a white field. The International Red Cross and Red Crescent Movement was begun in October 1863, in Geneva, Switzerland. The Red Cross emblem was first adopted at this time as a symbol of neutrality (not taking sides in a conflict). Instead of a red cross, a red crescent is used in Muslim countries. The Red Cross flag was first officially flown in the USA in 1881 (the year the US Red Cross was founded), when Clara Barton flew the flag in Dansville, New York, during an appeal for donations to help the victims of forest fires in Michigan (Source: enchantedlearning).
