Answer:
The outbreak of World War II was the result of a complex set of factors, but three of the most significant factors were:
The failure of appeasement policies: Following the Treaty of Versailles that ended World War I, Germany was left with a devastated economy and a reduced military. However, under the leadership of Adolf Hitler, Germany began rearming and expanding its territories, in violation of the treaty. Britain and France pursued a policy of appeasement, hoping to avoid another war, and allowed Germany to annex Austria and Czechoslovakia. This policy of appeasement only emboldened Hitler to continue his aggressive policies, eventually leading to the invasion of Poland and the start of World War II.
The failure of the League of Nations: The League of Nations was created after World War I to promote international cooperation and prevent another war. However, it was weakened by the refusal of the United States to join and the withdrawal of Japan, Germany, and Italy. The League's inability to take effective action to prevent the aggression of Germany, Japan, and Italy contributed to the outbreak of World War II.
The Molotov-Ribbentrop Pact: The Molotov-Ribbentrop Pact was a non-aggression agreement signed by Germany and the Soviet Union in 1939. The pact also included secret protocols that divided Eastern Europe into spheres of influence between Germany and the Soviet Union. The pact allowed Hitler to invade Poland without fear of a Soviet counterattack and enabled the Soviet Union to annex the Baltic states and parts of Finland. This pact contributed to the global scale of the war by creating a two-front war for Germany and allowing the Soviet Union to become a major player in the war.
Overall, these factors contributed to the outbreak of World War II and its eventual global scale by allowing Germany to become a major power in Europe, weakening the international institutions designed to prevent war, and creating a complex web of alliances and rivalries that spread the conflict across the globe.
