Final answer:
World War 2 began with Germany's invasion of Poland and the signing of the Molotov-Ribbentrop Pact. Japan's actions in Asia further escalated the conflict.
Step-by-step explanation:
Beginning of World War 2
World War 2 began on September 1, 1939, when Germany, under the leadership of Adolf Hitler, invaded Poland. This invasion marked the start of the war in Europe. Soon after, countries like France and the United Kingdom declared war on Germany in response to its aggressive actions.
Another significant event that contributed to the beginning of World War 2 was the signing of the Molotov-Ribbentrop Pact between Germany and the Soviet Union. This non-aggression pact allowed Germany to focus its efforts on conquering Western Europe without the fear of Soviet intervention.
Additionally, the expansionist policies of Japan in East Asia, particularly its invasion of China, also played a role in the escalation of the war.
