Political map of Europe & the Mediterranean 13 March 1938 (Anschluss): 1937 saw further global disruption with the Japanese invasion of China (Sino-Japanese War (1937-1945)). In March 1938, German troops entered Hitler's homeland of Austria (Anschluss), where they were greeted by the local population. The next day, Hitler (Adolf Hitler) announced the German annexation of Austria. Again this was in breach of the Treaty of Versailles (Treaty of Versailles) and again Britain and France did nothing.
