Hitler's foreign policy from 1933-1939 focused on three goals: destroying the Treaty of Versailles, uniting German speakers, and gaining Lebensraum. He withdrew Germany from the League of Nations in 1933 and began secret rearmament. Through threats and appeasement, he annexed the Rhineland, Austria, and the Sudetenland region of Czechoslovakia. In 1939, he invaded Poland, prompting Britain and France to declare war, starting World War II in Europe.
