The Treaty of Versailles (1919) was the peace settlement ending World War I between Germany and the Allied Powers; it forced Germany to accept blame, pay reparations, and give up territory, creating the "unsustainable peace" the AP World CED names as a cause of World War II.
The Treaty of Versailles was signed in 1919 at the Paris Peace Conference and officially ended the state of war between Germany and the Allied Powers. The treaty hit Germany hard. It included the War Guilt Clause (which made Germany accept responsibility for the war), demanded massive reparations payments, stripped Germany of territory and all of its colonies, and limited its military. It also created the League of Nations, a new international body meant to prevent future wars.
Here's the part that matters most for AP World: the treaty was supposed to build a lasting peace, and instead it built resentment. The CED literally calls the post-WWI settlement "unsustainable." Reparations crushed the German economy, the War Guilt Clause humiliated the German public, and that combination of economic pain and wounded nationalism gave Adolf Hitler and the Nazi Party their opening. Meanwhile, Germany's former colonies didn't get independence. They were handed to Britain and France as League of Nations mandates, which kept imperialism alive under a new name and fueled anti-imperial resistance.
The Treaty of Versailles lives in Unit 7 (Global Conflict, 1900-Present) and is one of the most connected terms in the whole unit. It directly supports AP World 7.6.A, where the essential knowledge names the "unsustainable peace settlement after World War I" as a cause of World War II. It also supports AP World 7.5.A, because the treaty's mandate system transferred German colonies to Britain and France, a continuity of imperial control between the wars. And it feeds AP World 7.4.A, since reparations and war debts shaped the interwar economic crisis that governments responded to in such different ways. If you're writing about causation in global conflict (Topic 7.9), Versailles is the hinge between the two world wars.

War Guilt Clause and Reparations (Unit 7)
These are the two most-tested pieces inside the treaty. The War Guilt Clause assigned blame to Germany, and that blame justified the reparations bill. Together they explain why ordinary Germans saw the treaty as a humiliation rather than a peace.
Causes of World War II / Adolf Hitler (Unit 7)
The CED's causal chain for WWII starts here. Versailles created economic misery and national humiliation, the Great Depression made both worse, and Hitler campaigned on tearing the treaty up. When you argue causation for WWII, Versailles is usually your starting evidence.
League of Nations and the Mandate System (Unit 7)
The treaty created the League, and the League handed Germany's former colonies to Britain and France as "mandates." That's imperialism with a new label, and it's the exact continuity in territorial holdings that LO 7.5.A asks you to explain. It also helps explain anti-imperial resistance movements like the Indian National Congress.
Economy in the Interwar Period (Unit 7)
Reparations chained the German economy to the Allies and the Allies' war debts to the US, so when the Great Depression hit, the crisis spread fast. The treaty is a big reason the interwar economy was so fragile in the first place.
Multiple-choice questions usually test the treaty through cause and effect. A stem might ask which treaty ended the war between Germany and the Allied Powers (that's Versailles), or ask you to connect the treaty's terms to interwar economic crisis or to the rise of fascism. On FRQs, no released prompt has required the term verbatim, but it's premium evidence for any LEQ or DBQ on the causes of World War II, continuity and change in empires between the wars, or the relative significance of causes of 20th-century conflict (Topic 7.9). The move to practice is going beyond "Versailles was harsh" to explaining the mechanism: humiliation plus reparations plus depression created the conditions fascism exploited.
The Treaty of Versailles is the document; the League of Nations is the organization the treaty created. The treaty punished Germany and redrew borders, while the League was supposed to keep the peace going forward. Bonus twist worth knowing: the United States signed neither, since the Senate refused to ratify the treaty, which left the League weak from day one.
The Treaty of Versailles, signed in 1919, officially ended World War I between Germany and the Allied Powers.
Its harshest terms were the War Guilt Clause, heavy reparations, military limits, and the loss of all German colonies.
The AP World CED calls the post-WWI settlement "unsustainable" and names it as a direct cause of World War II.
Germany's former colonies became League of Nations mandates under Britain and France, so imperialism continued between the wars instead of ending.
Reparations made the German and global economies fragile, helping the Great Depression spiral into political extremism.
On the exam, use Versailles as causation evidence linking World War I to fascism, the Depression, and World War II.
It was the 1919 peace treaty that ended World War I between Germany and the Allied Powers. It forced Germany to accept blame for the war, pay reparations, shrink its military, and surrender territory and colonies, and it created the League of Nations.
Not by itself, but it's a major cause. The CED lists the unsustainable peace settlement alongside the Great Depression, continued imperialism, and the rise of fascist regimes like Nazi Germany. Versailles created the resentment and economic strain that Hitler exploited.
The treaty is the peace agreement itself; the League is the international peacekeeping organization the treaty established. The US Senate rejected the treaty, so the United States never joined the League, which weakened it badly.
It was the provision forcing Germany to accept responsibility for World War I, which legally justified the reparations Germany had to pay. It became a rallying point for German nationalism and Nazi propaganda.
They were transferred to Great Britain and France as League of Nations mandates rather than becoming independent. AP World treats this as a continuity of imperial control between the wars, and it helped spark anti-imperial resistance movements.
