Answer: The major causes of World War II were numerous. They include the impact of the Treaty of Versailles following WWI, the worldwide economic depression, failure of appeasement, the rise of militarism in Germany and Japan, and the failure of the League of Nations.
World War II: World War I did not directly cause World War II. However, WW1 created several consequences which led to a second World War: New states in Eastern Europe who were weak and ripe for the taking by Hitler. A devastated Germany and France appeased Hitler to prevent another war. The First World War destroyed empires, created numerous new nation-states, encouraged independence movements in Europe's colonies, forced the United States to become a world power, and led directly to Soviet communism and the rise of Hitler.
