what caused world war two
The History Learning Site, 17 Mar 2015. 19 Jul 2016. 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.
