See all answers & explanations
1. Which event is widely recognized as the start of World War 2 in Europe?
Answer: Germany's invasion of Poland. Germany invaded Poland on September 1, 1939, and Britain and France — bound by treaty to defend the Poles — declared war on Germany two days later. On September 17 the Soviet Union invaded from the east under the secret terms of the Molotov-Ribbentrop Pact, and Poland was partitioned within weeks.
2. On December 7, 1941, Japan launched a surprise attack on which U.S. naval base, bringing America into the war?
Answer: Pearl Harbor. The attack killed over 2,400 Americans and damaged or destroyed 19 ships and more than 300 aircraft, and the United States declared war on Japan the next day. The sunken USS Arizona still leaks small drops of oil into the harbor more than 80 years later. Go deeper: Explosive History: A Chronicle of Infamous Bombings.
3. What was happening in Europe on May 10, 1940 — the day Winston Churchill became British prime minister?
Answer: Germany invaded the Low Countries that same day. Churchill took office the very day Germany's blitzkrieg rolled into Belgium, the Netherlands, and Luxembourg, ending the eight-month lull known as the Phoney War. He had spent much of the 1930s in the political wilderness warning Parliament about German rearmament.
4. How many code-named beaches did the Allies storm on D-Day, June 6, 1944?
Answer: 5. The landings hit five beaches — Utah, Omaha, Gold, Juno, and Sword — along roughly 50 miles of Normandy coast. Omaha was by far the bloodiest, its high bluffs and largely intact German defenses inflicting the heaviest casualties of the five.
5. Alan Turing's team at Bletchley Park built the "Bombe" machine to break messages from which German cipher device?
Answer: Enigma. The electromechanical Bombes sped up the daily breaking of Enigma settings, producing intelligence code-named Ultra that historians credit with shortening the war. Nearly 10,000 people worked at Bletchley Park — and the secret held until the 1970s.
6. Which German "vengeance weapon," first launched against Allied cities in 1944, was the world's first long-range guided ballistic missile?
Answer: The V-2 rocket. The V-2 climbed to the edge of space and fell on London and Antwerp faster than the speed of sound — no warning, no defense. Its grimmest statistic: an estimated 10,000–20,000 concentration-camp prisoners died building V-2s at Mittelbau-Dora, far more than the roughly 2,700 Londoners the rockets killed.

7. The Gestapo called which American agent — who worked in occupied France with a prosthetic leg she nicknamed "Cuthbert" — "the most dangerous of all Allied spies"?
Answer: Virginia Hall. Hall escaped France by hiking roughly 50 miles over the Pyrenees on her artificial leg, then returned disguised as an elderly milkmaid to keep organizing resistance networks. After the war she became one of the CIA's first female operations officers. Go deeper: Famous Female Spies: Women Who Infiltrated Enemy Lines.
8. Fanta was invented in wartime Germany when Allied embargoes cut off the ingredients needed to make which drink?
Answer: Coca-Cola. With Coke syrup unobtainable, Coca-Cola's German branch manager Max Keith improvised a new soda from what was left over — apple pomace, whey, and beet molasses — and named it after the German word "Fantasie." Go deeper: The Unknown History of Fanta’s Nazi Origins.
9. The U.S. Army asked Hershey to make its WW2 emergency chocolate deliberately taste only "a little better than" which humble food?
Answer: A boiled potato. In 1937, Army quartermaster Captain Paul Logan gave Hershey that exact brief so hungry soldiers wouldn't snack on their emergency rations early. Hershey produced some 3 billion Ration D bars, which GIs — noting the dense bar's digestive effects — nicknamed "Hitler's Secret Weapon."

10. Which Japanese city was the first ever struck by an atomic bomb, on August 6, 1945?
Answer: Hiroshima. The Hiroshima and Nagasaki bombings together killed an estimated 129,000–226,000 people and remain the only use of nuclear weapons in war. Nagasaki wasn't even the second mission's primary target — cloud cover over Kokura spared that city on August 9. Go deeper: Explosive History: A Chronicle of Infamous Bombings.
The World War 2 Quiz FAQ
What started World War 2?
World War 2 began in Europe on September 1, 1939, when Nazi Germany invaded Poland, prompting Britain and France to declare war on Germany two days later.
That invasion was the trigger, but the war's roots ran deeper. The harsh terms of the Treaty of Versailles after World War 1, the economic devastation of the Great Depression, and the rise of aggressive, expansionist regimes in Germany, Italy, and Japan created the conditions for conflict. Adolf Hitler's government pursued rearmament and territorial expansion through the 1930s — annexing Austria in 1938 and dismantling Czechoslovakia by early 1939 — while the Western democracies pursued a policy of appeasement that failed to stop him.
Historians also debate when the war truly "started," since fighting in Asia had already begun with Japan's full-scale invasion of China in July 1937 — the Second Sino-Japanese War — which many scholars now treat as the conflict's opening chapter in the Pacific. By this broader reading, World War 2 was less a single spark than the convergence of two regional wars, in Europe and Asia, into one global war by 1941.
Test what you know about the war's causes and outbreak in the quiz above.
Which country did Germany invade first?
Germany's first wartime invasion was Poland, launched on September 1, 1939 — the event that formally started World War 2 in Europe.
Germany had already expanded its borders before Poland, but not through invasion in the war-making sense. Austria was absorbed via the Anschluss in March 1938 without a shot fired, and Czechoslovakia followed: the Sudetenland was ceded under the Munich Agreement in September 1938, and Germany occupied the remaining Czech lands in March 1939, again without armed resistance.
Poland was different. When German forces crossed the border under a fabricated pretext, the Poles fought back, and Britain and France — bound by treaty to defend Poland — declared war on Germany within 48 hours. The invasion combined a massive conventional assault with new "blitzkrieg" tactics — fast-moving tanks and aircraft in close coordination — and Poland fell within about five weeks, its eastern half seized by the Soviet Union under the terms of the Molotov-Ribbentrop Pact.
How long did WW2 last?
World War 2 lasted almost exactly six years in its most commonly cited span — from Germany's invasion of Poland on September 1, 1939, to Japan's formal surrender on September 2, 1945.
The war didn't end all at once. Fighting in Europe stopped on May 8, 1945 — celebrated as V-E Day — when Germany surrendered unconditionally, while the war against Japan continued for nearly four more months. Japan announced its surrender on August 15, 1945 (V-J Day), after the atomic bombings of Hiroshima and Nagasaki and the Soviet Union's entry into the Pacific war, but the formal surrender document wasn't signed aboard the USS Missouri until September 2, 1945 — the date most historians treat as the war's official end.
The six-year figure also depends on where you start the clock. Some historians date the war's beginning to July 1937, when Japan launched its full-scale invasion of China, arguing the Asia-Pacific and European conflicts were really one continuous world war that merged rather than two wars that began separately. By that reckoning, the war lasted more than eight years.

How hard is this WW2 quiz?
Expect a moderate difficulty curve — this WW2 quiz mixes easy openers, mid-level questions, and a couple that trip up genuine history buffs.
The easier questions cover facts most people meet in school or the movies: how the war started, the attack on Pearl Harbor, and the first atomic bombing. The middle tier asks for specifics — how many beaches the Allies stormed on D-Day, which cipher machine the Bletchley Park "Bombe" attacked, and what was unfolding in Europe the day Churchill took office.
The hardest questions dig into the war's stranger stories, like the V-2 rocket program's brutal production line and the American spy the Gestapo considered the most dangerous Allied agent in France. If you're new to the subject, expect to score around the middle; if you've read deeply on World War 2, a perfect 10 is within reach — but not guaranteed.
