Which event is commonly cited as the immediate trigger for the outbreak of World War II?

• A. Invasion of Poland by Nazi Germany on September 1, 1939
• B. Munich Agreement
• C. Declarations of war on Germany by Britain and France
• D. Rise of fascist ideology

Answer: (A)

Germany’s invasion of Poland on 1 September 1939 is the moment that directly kicked off World War II. It violated Poland’s borders and sovereignty, and Britain and France had already promised to defend Poland. Their subsequent declarations of war in response to the invasion mark the start of the conflict among the major powers, making this event the immediate trigger. The Munich Agreement showed a policy of appeasement that allowed German expansion earlier, but it did not itself start the war. Declarations of war by Britain and France happened as a consequence of the invasion, not as the initial spark. The rise of fascist ideology provides background drivers for aggression, but it’s a broader influence rather than a single event that began the war.
