World War 2 Causes
Briefing: A world moving towards war
World War 2 did not begin because of one event alone. Several pressures built up over many years. After World War 1, the 1919 Treaty of Versailles made Germany accept responsibility for the war, give up territory, reduce its armed forces and pay reparations. Many Germans regarded these terms as unfair and humiliating. The treaty did not by itself make another war inevitable, but resentment created an opportunity for extreme political movements. The Great Depression began in 1929. Businesses closed and unemployment spread across many countries. In Germany, hardship and anger helped the Nazi Party gain support by promising jobs, national strength and the rejection of the Versailles settlement. Adolf Hitler became German chancellor. His dictatorship persecuted people, promoted racist ideas and rapidly expanded the armed forces in defiance of the treaty. In the 1930s, Germany took control of Austria and then demanded the Sudetenland, a region of Czechoslovakia where many German speakers lived. Britain and France agreed to Germany taking the Sudetenland at the 1938 Munich Agreement, hoping this concession would prevent a wider war. This policy is often called appeasement. In March 1939, Germany occupied the rest of the Czech lands, showing that Hitler's expansion would continue. Other countries also pursued expansion. Fascist Italy invaded Ethiopia in 1935. Japan had occupied Manchuria in 1931 and launched a full-scale invasion of China in 1937. The League of Nations, created to help countries settle disputes peacefully, could not stop these invasions. Its weakness made collective security—the idea that countries would act together against aggression—less convincing. On 1 September 1939, Germany invaded Poland. Britain and France declared war on Germany on 3 September. Australia, as a member of the British Empire, also declared that it was at war with Germany on 3 September 1939.
