In 1944, the ICRC received its second Nobel Peace Prize. As in World War I, it received the only Peace Prize awarded during the main period of war, 1939 to 1945. At the end of the war, the ICRC worked with national Red Cross societies to organize relief assistance to those countries most severely affected. In 1948, the Committee published a report reviewing its war-era activities from 1 September 1939 to 30 June 1947. The ICRC opened its archives from World War II in 1996.
