Germany renounced the Versailles treaty and remilitarized the Rhineland in March 1936. Germany had already resumed conscription and announced the existence of a German air force, the Luftwaffe, and naval force, the Kriegsmarine in 1935. Germany annexed Austria in 1938, the Sudetenland from Czechoslovakia, and the Memel territory from Lithuania in 1939. Germany then invaded the rest of Czechoslovakia in 1939, creating the Protectorate of Bohemia and Moravia and the country of Slovakia.
