 Following the adoption of the Statutes of the International Red Cross in 1928 (revised in 1952 and 1986, amended in 1995 and 2006), the National Societies of the Nordic Red Cross (Denmark, Finland, Sweden and Norway) returned to the league after resigning three years earlier because of the discords within the Red Cross movement.The Alliance of the Red Cross and Red Crescent Societies of the Soviet Union joined the league during the XVth International Conference in 1934.By the mid-1930s, the league became truly universal, with 58 registered National Societies.
