Final answer:
The cause of the beginning of World War II was the aggressive actions of Nazi Germany and the failure of the international community to respond effectively.
Step-by-step explanation:
The cause of the beginning of World War II was the aggressive actions of Nazi Germany and the failure of the international community to respond effectively. Adolf Hitler, the leader of Germany, sought to expand German territory, violate the terms of the Treaty of Versailles, and establish a dominant fascist empire. His invasion of Poland in 1939 triggered the war, as France and Britain declared war on Germany in response.
Another important factor was appeasement, a policy followed by Western democracies that aimed to avoid another devastating war. They allowed Hitler to violate treaties with relative impunity, hoping that he would be satisfied. However, this only emboldened Hitler and ultimately led to the outbreak of the war.
Furthermore, the economic hardships of the Great Depression and the desire for resources and territory also played a role in fueling the conflict. Germany and Japan, for example, sought to expand their influence and secure resources through military aggression.
