Sanctions

Sanctions are penalties (economic, trade, military, or diplomatic restrictions) that countries or international bodies impose on a target state to change its behavior; in AP World, the League of Nations' weak sanctions against aggressors like Italy and Japan in the 1930s are a key cause of World War II.

What are Sanctions?

Sanctions are punishments short of war. Instead of sending troops, countries (or international organizations like the League of Nations) cut off trade, freeze assets, restrict weapons sales, or break diplomatic ties to pressure a target into changing its behavior. The logic is simple. Make aggression expensive, and aggressors will back down.

In AP World, sanctions show up most clearly in Topic 7.6 as part of the failed response to fascist expansion in the 1930s. When Japan invaded Manchuria in 1931 and Italy invaded Ethiopia in 1935, the League of Nations either imposed no sanctions or imposed sanctions so weak they changed nothing. Italy kept buying oil. Japan simply quit the League. That failure taught Hitler and Mussolini that aggression would go unpunished, which fed directly into the appeasement era and the outbreak of World War II.

Why Sanctions matter in AP World

Sanctions sit inside Unit 7 (Global Conflict, 1900-Present) under Topic 7.6, supporting learning objective 7.6.A, which asks you to explain the causes and consequences of World War II. The CED's essential knowledge lists the unsustainable post-WWI peace settlement, the Great Depression, continued imperialist aspirations, and aggressive fascist regimes as the war's causes. Sanctions are the connective tissue between those causes. The League of Nations was supposed to enforce the postwar order through collective security and sanctions, but Depression-era governments would not risk trade or war to enforce them. When you write about why aggression by Germany, Italy, and Japan went unchecked, failed sanctions are your evidence.

How Sanctions connect across the course

Ethiopia and Mussolini (Unit 7)

Italy's 1935 invasion of Ethiopia is the textbook sanctions failure. The League of Nations imposed limited economic sanctions on Italy but left out oil, the one resource Mussolini's war machine actually needed. Italy conquered Ethiopia anyway, and the League looked toothless.

Japanese expansion in Manchuria (Unit 7)

After Japan invaded Manchuria in 1931, the League condemned the invasion but enforced no real sanctions. Japan just withdrew from the League and kept expanding. This is the moment collective security visibly broke down in Asia.

Great Depression (Unit 7)

The Depression explains why sanctions failed. Governments desperate to protect their own trade and employment were unwilling to cut off commerce with aggressors, so economic punishment stayed half-hearted by design.

Adolf Hitler and the Axis Powers (Unit 7)

Hitler watched sanctions fail against Italy and Japan and drew the obvious lesson. He remilitarized the Rhineland in 1936 and annexed territory with little pushback beyond appeasement, accelerating the slide into World War II.

Are Sanctions on the AP World exam?

Sanctions usually appear inside questions about the causes of World War II, not as a standalone definition. Multiple-choice stems and short-answer prompts often pair a 1930s source (a League of Nations resolution, a speech about Ethiopia or Manchuria) with questions asking why international responses to aggression failed. Practice questions in this vein ask things like what might have happened if the League had effectively enforced sanctions against Japan after Manchuria, or how appeasement and Japanese expansionism led to war. No released FRQ has used the word verbatim, but failed sanctions make strong evidence in any LEQ or DBQ on the causes of WWII. The move you need to make is causal. Connect weak sanctions to emboldened aggressors to the outbreak of war.

Sanctions vs Embargo

An embargo is one specific type of sanction, a ban on trade (or on certain goods) with a target country. Sanctions is the umbrella term covering embargoes plus other penalties like asset freezes, travel bans, and diplomatic isolation. If you say 'embargo,' you mean trade was cut off. If you say 'sanctions,' you could mean any of these tools. The League's measures against Italy in 1935 were partial economic sanctions, but crucially they never included an oil embargo, which is exactly why they failed.

Key things to remember about Sanctions

  • Sanctions are penalties short of war, including trade restrictions, asset freezes, and diplomatic isolation, designed to pressure a country into changing its behavior.

  • In AP World, sanctions matter most in Topic 7.6 because the League of Nations' failure to enforce them against Japan (Manchuria, 1931) and Italy (Ethiopia, 1935) is a major cause of World War II.

  • The Great Depression undermined sanctions because governments protecting their own economies refused to cut off trade with aggressor states.

  • Failed sanctions emboldened Hitler, Mussolini, and Japanese leaders by proving that aggression carried little cost, which fed directly into appeasement.

  • An embargo is one kind of sanction (a trade ban); sanctions is the broader category, so use the terms precisely in your writing.

  • On the exam, use failed sanctions as causal evidence for why fascist aggression went unchecked, supporting learning objective 7.6.A.

Frequently asked questions about Sanctions

What are sanctions in AP World History?

Sanctions are penalties, usually economic, trade, or diplomatic restrictions, that countries or international bodies impose on a state to punish aggression or force a policy change. In AP World, they appear in Topic 7.6 as the League of Nations' failed tool against 1930s aggression.

Did League of Nations sanctions stop Italy or Japan in the 1930s?

No. The League imposed only partial sanctions on Italy after its 1935 invasion of Ethiopia (leaving out oil), and it never effectively sanctioned Japan after the 1931 invasion of Manchuria. Japan simply withdrew from the League, and both aggressors kept expanding.

What's the difference between sanctions and an embargo?

An embargo is a specific type of sanction that bans trade with a country or blocks certain goods. Sanctions is the broader term that also includes asset freezes, arms restrictions, and diplomatic isolation.

How did failed sanctions cause World War II?

When the League of Nations failed to punish Japan in Manchuria and Italy in Ethiopia, fascist leaders learned aggression carried no real cost. That emboldened Hitler to remilitarize the Rhineland in 1936 and pursue expansion, while Britain and France fell back on appeasement instead of enforcement.

Why didn't countries enforce stronger sanctions during the Great Depression?

Depression-era governments were desperate to protect their own trade, jobs, and economies, so cutting off commerce with aggressor states felt self-destructive. That economic self-interest is why sanctions on Italy excluded oil and why collective security collapsed.
