The Russian Revolution and Soviet state: The 1917 revolutions, civil war, and the Bolshevik consolidation of a one-party state under Lenin and Stalin.
The peace settlement and its consequences: Versailles terms, new states in central and eastern Europe, and lasting grievances over reparations and borders.
Interwar economic and political crisis: Inflation, the Great Depression, and the weakening of parliamentary democracy across the continent.
Fascism and totalitarian regimes: Mussolini and Hitler, propaganda and terror, and Stalinist collectivization and purges as comparison cases.

Sample Global Conflicts questions

Practice questions, not yet expert-reviewed

Original practice questions written to the published framework for this section. No expert has reviewed them, and they are not taken from any official exam. Try each one before you open the answer.

Question 1Foundational
Which form of warfare on the Western Front from 1914 to 1918 produced years of stalemate along fortified lines of dug-in positions?
1. ATrench warfare
2. BBlitzkrieg
3. CGuerrilla warfare
4. DNaval blockade
Show answer
Answer: A. Trench warfare
Machine guns, barbed wire, and massed artillery gave defenders an enormous advantage, so armies dug in and offensives bought a few miles at appalling cost. Blitzkrieg is the tempting distractor because it also names a way of fighting, but it describes the fast armored and air attacks Germany used in 1939 and 1940.
Key insight: Technology outran tactics in 1914, and the resulting stalemate is what made the war total.
Question 2Foundational
Which 1938 agreement allowed Germany to annex the Sudetenland in exchange for Hitler's promise of no further territorial demands?
1. AThe Munich Agreement
2. BThe Treaty of Versailles
3. CThe Nazi-Soviet Pact
4. DThe Locarno treaties
Show answer
Answer: A. The Munich Agreement
Britain and France accepted the dismemberment of Czechoslovakia in the hope of avoiding war, and Germany occupied the rest of the country within six months. The Nazi-Soviet Pact is the tempting distractor because it also preceded the war, but it was the August 1939 nonaggression agreement that divided eastern Europe between Germany and the Soviet Union.
Key insight: Appeasement is best explained by the memory of 1914 to 1918 rather than by simple cowardice.
Question 3Intermediate
Which economic policy did Lenin adopt in 1921, permitting limited private trade and small private enterprise in order to revive the Soviet economy?
1. AThe New Economic Policy
2. BWar communism
3. CThe first Five-Year Plan
4. DCollectivization
Show answer
Answer: A. The New Economic Policy
After famine and revolt exposed the failure of forced grain requisitioning, the New Economic Policy let peasants sell surpluses and allowed small businesses to operate for profit. War communism is the tempting distractor because it is the policy the New Economic Policy replaced, and Stalin later reversed course again with five-year plans and collectivization.
Key insight: Soviet economic policy swung between market concessions and command planning, and each swing had political motives.
Question 4Intermediate
Which German economic crisis of 1923 destroyed the value of savings and badly damaged confidence in the Weimar Republic?
1. AHyperinflation
2. BDeflation
3. CA stock market crash
4. DMass unemployment caused by automation
Show answer
Answer: A. Hyperinflation
Reparations pressure, the French occupation of the Ruhr, and the printing of money to support striking workers drove prices to astronomical levels and wiped out middle-class savings. Mass unemployment is the tempting distractor because it also devastated Weimar Germany, but that came with the Great Depression after 1929.
Key insight: Weimar faced two separate economic catastrophes, and confusing 1923 with 1929 breaks the causal chain.
Question 5Advanced
At which January 1942 meeting did senior Nazi officials coordinate the administration of the plan they called the final solution?
1. AThe Wannsee Conference
2. BThe Nuremberg rally
3. CThe Munich Conference
4. DThe Potsdam Conference
Show answer
Answer: A. The Wannsee Conference
Officials from across the German state met at Wannsee to organize the deportation and murder of Europe's Jews, which shows how deeply the ordinary bureaucracy was implicated. The Nuremberg rally is the tempting distractor because Nuremberg is associated both with Nazi ideology and with the postwar trials, but the rallies were propaganda spectacles rather than administrative meetings.
Key insight: The Holocaust escalated in stages, and Wannsee shows the machinery of state coordinating the killing.
