The causes of World War Two can be divided into long term causes and short term causes. There can be little doubt that one of the long term causes of the war was the anger felt in Weimar Germany that was caused by the Treaty of Versailles. Another long term cause was the obvious inability of the League of Nations to deal with major international issues. In the 1930’s these would have been inManchuria and Abyssinia. In both conflicts the League showed that it was unable to control those powers that worked outside of accepted international law. In the case of Manchuria it was Japan and in Abyssinia it was Mussolini’s Italy.
