The Sudeten Germans, led by Konrad Henlein and financed by Hitler, began making claims of mistreatment by the Czech government and increased hostile activities aimed at uniting the Sudetenland region of Czechoslovakia with Germany. This convinced Britain and France that ceding the territory to Germany was needed to avoid war. In 1938, Britain, France and Italy pressured Czechoslovakia to surrender the Sudetenland to Germany at the Munich Agreement, appeasing Hitler's demands but weakening Czechoslovakia's defenses.
