The Great Depression started with the 1929 U.S. stock market crash and spread to Europe because European economies relied heavily on American investment capital. In AP European History, this topic asks you to connect trade, debt, overproduction, tariffs, and financial panic to the collapse of democracy and the rise of extremist politics in the interwar years.
Why This Matters for the AP European History Exam
This topic is central to understanding why democracy struggled in interwar Europe. You need to explain the causes and effects of the global economic crisis of the 1920s and 1930s, and connect that economic collapse to the political radicalization that followed. The Depression is a strong example for causation reasoning: economic weakness leads to political instability, which leads to the rise of fascism and authoritarian regimes covered in Topic 8.6.
It also works well for continuity and change over time. The crisis shifted how Europeans thought about the relationship between the individual and the state, pushing some countries toward government intervention in the economy and others toward dictatorship. Expect to use the Depression as evidence in arguments about why World War II became possible.
Key Takeaways
- The Great Depression came from weaknesses in international trade and monetary practices, not just the 1929 crash alone.
- Main causes: World War I debt, nationalistic tariff policies, overproduction, depreciated currencies, disrupted trade patterns, and speculation.
- Europe depended on American investment capital, so when the U.S. cut off capital flows after the 1929 crash, European economies collapsed.
- The Depression undermined Western European democracies and helped extremist movements gain support.
- Even though governments tried new economic theories and political alliances, Western democracies failed to overcome the Depression.
- Examples of new responses include Keynesianism in Britain, cooperative social action in Scandinavia, and Popular Front policies in France.
Causes of the Great Depression
The crisis did not appear out of nowhere. A mix of postwar debt and structural economic weaknesses had been building through the 1920s.
World War I Debt and Reparations
World War I left European nations with heavy debts. The war was extremely expensive, and countries borrowed heavily, especially from the United States, to pay for it. Those loans were supposed to be repaid afterward.
The Treaty of Versailles also assigned guilt to Germany and demanded reparations. This burden hurt the Weimar Republic's ability to build a stable economy and contributed to hyperinflation in the early 1920s.
The Dawes Plan (1924) is a useful example of how interconnected the system was. Under it, the U.S. loaned money to Germany, Germany paid reparations to France and Britain, and those countries repaid their war debts to the U.S. This circular flow temporarily stabilized Germany but made Europe dependent on continued American lending.
Stock Market Speculation and the 1929 Crash
During the 1920s, a consumer-driven economy grew in the United States, and many people invested in the stock market. A lot of them bought "on the margin," paying only a small fraction of a stock's price and borrowing the rest. This left investors and the market highly exposed.
In 1929, the stock market crashed. Stock prices collapsed, wealth vanished, and banks began to fail. Because European recovery depended on post-WWI American investment capital, the U.S. cutting off those capital flows triggered financial collapse across Europe. Unemployment, poverty, and social unrest followed.
Effects of the Great Depression in Europe
The economic damage had direct political consequences.
Weakened Democracies and Radical Politics
Democratically elected governments struggled to respond to mass unemployment and economic collapse, and many could not provide effective solutions. That failure fed political discontent and pushed voters toward extremist movements on both the far right and far left.
In several countries, the crisis helped authoritarian and fascist movements gain support by promising national strength and order. The economic instability of these years is a key reason why fascism, covered in Topic 8.6, became so appealing to disillusioned populations.
Economic Nationalism
Countries turned inward, emphasizing self-sufficiency and high tariffs instead of cooperation. This economic nationalism deepened the crisis by disrupting trade even further and weakening international cooperation at the worst possible time.
New Economic Theories and Responses
As traditional policies failed, governments and thinkers experimented with new approaches. These are good illustrative examples, not required terms, but they show how different states responded.
Keynesianism in Britain
John Maynard Keynes argued that governments should intervene in the economy to keep it stable. He supported government spending to boost demand and reduce unemployment, challenging older ideas that favored limited government involvement. His thinking gained influence during the 1930s.
Cooperative Social Action in Scandinavia
In Denmark, Sweden, and Norway, governments, employers, and workers cooperated to spread the burden of the Depression and protect living standards. These countries built social welfare programs aimed at reducing poverty and promoting stability.
Popular Front Policies in France
The Popular Front, a coalition of left-wing parties led by Léon Blum, pushed economic and social reforms to deal with the Depression. Policies included shorter workweeks and paid vacations for workers. Despite these efforts, France continued to face high unemployment and political instability.
These responses fit the larger pattern: despite rethinking economic theory and forming new political alliances, Western democracies could not fully overcome the Depression and were weakened by extremist movements.
How to Use This on the AP European History Exam
Causation
The clearest use of this topic is cause and effect. Be ready to explain the causes (WWI debt, tariffs, overproduction, depreciated currencies, disrupted trade, speculation) and the effects (weakened democracies, radical political responses). A strong answer connects American investment dependence to the speed and depth of Europe's collapse.
Continuity and Change
Use the Depression to show how ideas about the state and the economy shifted. Some countries moved toward more government intervention, while others turned to dictatorship. This connects directly to the larger interwar story.
Using Sources Effectively
If you get a source about the Depression, think about who is speaking and why. A government leader defending new spending programs, an unemployed worker, and a fascist politician would all describe the crisis very differently. Use point of view and purpose to explain the source's argument.
Common Trap
Do not stop at the 1929 crash. The crash was a trigger, but exam answers earn more by explaining the underlying weaknesses in international trade and monetary practices that made the collapse possible.
Common Misconceptions
- The 1929 crash alone caused the Depression. The crash was a trigger, but the real causes were structural: WWI debt, tariffs, overproduction, weak currencies, disrupted trade, and speculation.
- The Depression was only an American problem. Europe was deeply affected because its recovery depended on American investment capital, so when that capital stopped flowing, European economies collapsed.
- Democracies fixed the Depression with new policies. Western democracies tried new theories and alliances but failed to overcome it, and they were weakened by extremist movements in the process.
- Keynesianism, the Scandinavian model, and the Popular Front are required terms. These are helpful examples of how different countries responded, not required content you must memorize by name.
- Economic nationalism helped countries recover. High tariffs and self-sufficiency policies actually disrupted trade further and made the global crisis worse.

Frequently Asked Questions
What caused the Great Depression in AP Euro?
In AP Euro, the Great Depression came from deeper weaknesses in international trade and monetary systems, including World War I debt, tariffs, overproduction, depreciated currencies, disrupted trade, and speculation.
How did the 1929 crash affect Europe?
The 1929 U.S. stock market crash cut off American investment capital that many European economies depended on after World War I. That helped turn financial weakness into a wider economic and political crisis across Europe.
What was the Dawes Plan?
The Dawes Plan was a 1924 arrangement in which U.S. loans helped Germany pay reparations to Britain and France, which then repaid war debts to the United States. It stabilized Germany temporarily but made Europe dependent on American lending.
How did the Great Depression weaken democracies?
Mass unemployment and economic collapse made democratic governments look ineffective. As confidence fell, extremist parties gained support by promising stronger state action and national renewal.
What responses did European governments try?
European responses included Keynesian ideas in Britain, cooperative social action in Scandinavia, and Popular Front policies in France. These show that many democracies tried new economic theories and political alliances, even though the crisis persisted.
