 It was described as for use when the ICRC, the International Federation of Red Cross and Red Crescent Societies and the National Red Cross and Red Crescent Societies operate together for the purposes of a humanitarian emergency, or a theme or campaign of global concern.The IFRC has come into conflict with the ICRC at various times, first and foremost when the American Red Cross threatened to supplant the ICRC with its creation of the league as "a real international Red Cross" after the First World War.Several agreements about the respective roles of the organizations helped to smooth relations, beginning with the agreement of 1928, the 1997 Seville Agreement and most recently the Supplementary Measures of 2005.
