Czechoslovakia was a mandate created after World War 1 that included the Sudetenland region with a large German population. Hitler threatened to take the Sudetenland by force in 1938, heightening tensions in Europe. At the Munich Agreement in September 1938, Britain, Germany, France and Italy decided Czechoslovakia's fate by giving the Sudetenland to Germany without Czech representation. While this temporarily avoided war, it set the stage for Germany's invasion and occupation of Czechoslovakia the following year, ending the failed policy of appeasement.
