The composition of the Council was changed several times. The number of non-permanent members was first increased to six on 22 September 1922 and to nine on 8 September 1926. Werner Dankwort of Germany pushed for his country to join the League; joining in 1926, Germany became the fifth permanent member of the Council. Later, after Germany and Japan both left the League, the number of non-permanent seats was increased from nine to eleven, and the Soviet Union was made a permanent member giving the Council a total of fifteen members. The Council met, on average, five times a year and in extraordinary sessions when required. In total, 107 sessions were held between 1920 and 1939.
