In 1939, Hitler expanded the German Navy and, in violation of the Munich Agreement, occupied parts of the Sudetenland in Czechoslovakia. Germany then established the Protectorate of Bohemia and Moravia. This protectorate included those portions of Czechoslovakia that had not already been incorporated into Germany. On August 30, 1939, the German Reich issued an ultimatum to Poland concerning the Polish Corridor and the Free City of Danzig. On September 1st, without waiting for a response to its ultimatum, Germany invaded Poland. Much to Hitler’s surprise, England honored its treaty with Poland. Neville Chamberlain declared war on Germany, thereby ushering in another World War. Officially, “The Second World War” in Europe was started by the German Reich when it attacked Poland, although at the time Germany blamed the Treaty of Versailles.
