The previous lesson showed that the post–First World War settlement created a fragile international order: new borders and states, unresolved minority disputes, imperial mandates, and a League of Nations without dependable enforcement. The Great Depression did not create all of those weaknesses, but it made them far harder to manage.
This lesson explains two connected effects of the economic collapse after 1929. First, states increasingly chose national economic survival over international coordination. Second, mass unemployment, austerity, and political deadlock damaged confidence in democratic governments—most dramatically in Germany—while strengthening authoritarian and extremist alternatives. The connection matters: a world less willing to cooperate economically was also less able and willing to resist aggression politically.
A financial crisis in an interdependent world
The Great Depression began with the American financial crash of 1929, but it became a global depression because the world economy was already deeply interconnected. International trade, investment, debt, reparations, and currencies tied national economies together.
The postwar financial system was especially precarious. Germany owed reparations to the former Allied powers; Britain and France, in turn, owed wartime debts to the United States. During the comparatively stable later 1920s, American loans—many of them short-term—helped Germany pay reparations and supported European recovery. This arrangement depended on continuing American credit.
When American banks and investors withdrew funds after 1929, countries dependent on foreign capital suffered sharply. German banks and businesses faced particular pressure, and the banking crisis of 1931 intensified unemployment and political instability. Meanwhile, falling demand reduced exports worldwide. Commodity producers in Latin America, Africa, Asia, and Australasia saw the value of their exports collapse; industrial countries faced factory closures and unemployment.
A simplified chain of pressure looked like this:
- Financial panic and falling demand reduced production, investment, and employment.
- Banks and investors recalled loans, spreading the crisis across borders.
- Governments lost tax revenue while demands for unemployment relief increased.
- States tried to protect their own workers, currencies, and industries.
- Those national measures often shifted hardship onto other countries, worsening the international slump.
The economic system built during the 1920s was therefore not simply “globalized”; it was interdependent without being securely governed. There was no institution with the authority or resources to coordinate a global recovery, stabilize currencies, or provide emergency lending on the necessary scale.
The Great Depression and 'Embedded Liberalism'
Watch the opening of Gresham College’s The Great Depression and “Embedded Liberalism”. It introduces the 1933 World Monetary and Economic Conference and then shows why Britain, the United States, and France pursued incompatible recovery strategies.
Watch the conference introduction for the scale and eventual failure of the London meeting. Then watch Britain's strategy, focusing on how leaving the gold standard, imperial preference, and protective tariffs could aid a national recovery while creating friction with other economies.
From internationalism to economic nationalism
A depression forces governments to make choices under intense pressure. Leaders were accountable above all to citizens facing joblessness, debt, and insecurity at home. Many concluded that their country could recover only by defending its own market against foreign competition.
This turn toward economic nationalism took several forms:
| Policy | Immediate national purpose | International consequence |
|---|---|---|
| Tariffs and import quotas | Shield domestic firms and jobs from foreign goods | Other states retaliated; trade contracted further |
| Currency devaluation | Make exports cheaper and imports more expensive | Encouraged competitive devaluations and monetary conflict |
| Exchange controls | Preserve scarce foreign currency and manage debt payments | Restricted trade and capital movement |
| Imperial preference | Give favorable access to markets within an empire | Divided the world into competing trade blocs |
| Autarky | Reduce dependence on foreign imports | Encouraged economic isolation and, in some states, territorial expansion for resources |
The term beggar-thy-neighbor describes policies intended to improve one country’s position by transferring costs to others. It does not mean that every policy-maker was malicious or irrational. A tariff might genuinely protect some domestic jobs; a currency devaluation might relieve domestic debtors. But when many governments acted this way simultaneously, each country’s attempt at protection reduced markets and purchasing power elsewhere. The aggregate result was a smaller, more divided world economy.
The American Smoot-Hawley Tariff of 1930 became the most famous symbol of this trend. It raised duties on thousands of imports. It did not single-handedly cause the Depression, which had multiple causes, but it encouraged retaliation and helped turn a severe downturn into an international trade collapse. Britain subsequently adopted imperial preference, favoring trade within the British Empire. Other powers built their own protected economic zones.
The gold standard added another problem. Under this monetary system, currencies were tied to fixed quantities of gold. Governments feared that devaluing their currency or expanding credit would threaten confidence and provoke capital flight. Maintaining the system often meant deflationary policies: cutting spending, raising taxes, reducing wages, and keeping interest rates high. Such measures could preserve a currency’s exchange value, but they also deepened unemployment and social distress.
Britain abandoned the gold standard in 1931; the United States followed in 1933. France held on longer. These differing choices reflected real differences in national circumstances, but they made a common program more difficult.
The Great Depression and U.S. Foreign Policy - History State Gov
Read the U.S. State Department’s concise account of how the Depression undermined international economic coordination and encouraged American withdrawal from foreign crises. It will help distinguish economic isolation from complete indifference to events abroad.
In the section “The International Depression,” read the full section. Focus on the changing roles of Britain and the United States and on the failure of the London Economic Conference. Then, in the following section, “Isolationism,” read the account of American isolationism. Note the connection between domestic political pressure and limited responses to aggression abroad.
The London Economic Conference: cooperation attempted, cooperation defeated
The World Monetary and Economic Conference, held in London in 1933, makes the problem visible. Delegates from dozens of countries met to discuss currencies, debt, trade barriers, and recovery. Yet they disagreed about priorities.
- Britain favored policies that supported recovery in sterling and its imperial trading system.
- France prioritized currency stability and preserving the gold standard.
- The Roosevelt administration prioritized American domestic recovery, including the freedom to devalue the dollar and raise prices.
The conference’s failure was not simply the fault of one leader or one country. The participating governments disagreed about what caused the crisis and about which domestic groups should bear its costs. International compromise could constrain each government’s ability to respond at home. In that sense, the Depression transformed economic policy into a test of political legitimacy.
The result was a serious blow to the ideal of international cooperation. If major powers could not coordinate against economic collapse, confidence in their ability to cooperate against military aggression was weakened as well.
Why economic crisis put democracies under pressure
Economic suffering does not automatically produce dictatorship. Democracies survived the Depression in Britain, the United States, Sweden, and elsewhere. Still, democratic governments were particularly vulnerable when they seemed unable to provide employment, social protection, or decisive leadership.
The pressure worked through several mechanisms.
First, hardship damaged the credibility of established parties. Moderate parties often defended balanced budgets, limited welfare spending, or international financial commitments. When those policies appeared to coincide with mass unemployment, voters could conclude that conventional parliamentary politics had failed.
Second, crisis made compromise harder. A coalition government may function when there is enough prosperity to distribute benefits and accommodate competing interests. In a depression, each decision about taxes, wages, unemployment insurance, or public spending creates immediate losers. Parliamentary bargaining becomes more brittle.
Third, extremist movements could turn distress into a political story. They offered simple explanations, identifiable enemies, and promises of national renewal. The enemies might be foreign creditors, international institutions, ethnic or religious minorities, communists, wealthy elites, or allegedly corrupt politicians. This scapegoating was not a natural response to hardship; it was a political choice, actively promoted through propaganda and organization.
Fourth, democratic leaders sometimes governed around parliaments. Emergency powers could appear necessary during a crisis, but their repeated use weakened habits of legislative government and made authoritarian solutions seem normal.
Germany illustrates all four mechanisms, but it must be treated as a specific case rather than a universal model.
Weimar Germany: crisis, constitutional erosion, and the Nazi breakthrough
The Weimar Republic was already burdened before 1929. It had emerged from military defeat and revolution; opponents spread the false “stab-in-the-back” myth to deny responsibility for Germany’s defeat; the republic had endured hyperinflation in 1923 and persistent political violence. Many conservatives, military leaders, and nationalists never accepted democratic government as legitimate.
The Depression added a devastating new crisis. Germany’s economy depended heavily on foreign loans, especially from the United States. When that credit dried up, firms failed, banks collapsed, and unemployment rose to roughly six million by 1932.
The government of Chancellor Heinrich Brüning responded largely through austerity: cuts in public expenditure and wages, tax increases, and efforts to maintain financial credibility. These choices were shaped by fear of inflation, dependence on foreign creditors, and the continuing political burden of reparations. But to many unemployed Germans, austerity looked like proof that the republic could not protect them.
Parliamentary government then eroded. In 1930, disagreement over unemployment insurance brought down the governing coalition. Brüning increasingly relied on Article 48 of the Weimar constitution, which allowed the president to issue emergency decrees. Article 48 was legal, but using it repeatedly shifted power away from the Reichstag. Democracy was being weakened from within before Hitler became chancellor.
The Nazi Party exploited this environment. It promised work, national unity, an end to the Versailles settlement, and renewed German strength. Its message fused economic desperation with racism, antisemitism, anti-communism, and a cult of leadership. Nazi electoral support expanded dramatically after 1929, though the party never won an absolute majority of the popular vote. Hitler became chancellor in January 1933 because conservative elites believed they could use and control him, not because a majority of Germans voted directly for a Nazi dictatorship.
James Sheehan, How and Why Democracies Fail: The Fall of Weimar Germany
Watch Professor James Sheehan’s Stanford CDDRL lecture, How and Why Democracies Fail: The Fall of Weimar Germany. These segments place Weimar’s collapse in the wider interwar decline of democracy and explain how the Depression narrowed Germany’s political options.
Watch the wider context to see why Germany was part of a broader European crisis of democracy rather than an isolated exception. Then watch the Depression crisis, concentrating on unemployment insurance, the collapse of the governing coalition, and why the economic emergency changed political possibilities.
The following 1932 poster condenses the Nazi political appeal into a single claim.
Its visual argument is carefully constructed. The crowded figures include workers, older people, a mother and child, and people who appear exhausted or anxious. Their expressions communicate collective suffering, while the oversized word “HITLER” visually dominates the population it claims to rescue. The poster offers neither a specific economic program nor evidence; it replaces complexity with an emotional promise of salvation through one leader.
As historical evidence, the poster tells us much about Nazi strategy and political language. It does not, by itself, prove that all Germans believed the message, nor does it establish that poverty alone made Nazism inevitable. Its value lies in showing how a movement could convert economic crisis into an authoritarian appeal.
Democratic adaptation, authoritarian opportunity, and international danger
It is important to avoid a deterministic conclusion. The Depression weakened many democracies, but it did not make democratic survival impossible.
Some democratic governments adapted through reform. In the United States, Franklin Roosevelt’s New Deal expanded relief, public works, regulation, and social protection. Britain’s National Government remained parliamentary despite major political realignment and economic hardship. Other states developed stronger welfare policies. These measures did not end all suffering, but they helped some democracies retain legitimacy by showing that elected government could act.
Other systems moved toward authoritarianism, military rule, or increasingly restricted democracy. Germany was the most consequential case, but it was not alone. In Japan, economic insecurity, disillusionment with party politics, and the search for protected markets strengthened the political influence of military and nationalist forces. Fascist Italy had already become a dictatorship before the Depression, but the global crisis reinforced the appeal of autarky, rearmament, and imperial expansion.
This produces the central link between domestic crisis and international conflict:
- Economic nationalism divided states into rival blocs and made collective recovery less likely.
- Domestic hardship made public support for costly international commitments harder to sustain.
- The United States focused primarily on recovery at home and remained reluctant to intervene abroad.
- Aggressive regimes increasingly portrayed conquest, resource control, and national self-sufficiency as solutions to economic vulnerability.
- The League of Nations depended on cooperation among states that were becoming less cooperative.
The Depression therefore did not “cause World War II” in a single, direct sense. War required further choices: Japanese expansion in Asia, Italian imperial aggression, Nazi rearmament and territorial expansion, the failure of collective security, and diplomatic decisions by other powers. But the Depression made the international system less cohesive and made democratic politics in several states more fragile precisely when resilience was most needed.
A concise explanation to carry forward
A strong explanation of the Depression’s political consequences should include all three layers:
- Economic mechanism: financial interdependence, collapsing trade, debt crises, deflation, and unemployment spread the shock across borders.
- International mechanism: tariffs, currency conflict, imperial preference, autarky, and the failure of the London Conference replaced cooperation with competing national strategies.
- Political mechanism: hardship and governmental deadlock undermined moderate parties; extremists exploited grievances; in some countries, emergency rule and elite choices helped erode democracy.
The key qualification is equally important: economic crisis created conditions and pressures, not an unavoidable outcome. Democracies could respond through reform, while authoritarian movements had to persuade, intimidate, organize, and ultimately receive assistance from established elites.
Key takeaways
The Great Depression weakened international cooperation because the global economy was highly connected but poorly coordinated. As credit collapsed and trade contracted, governments adopted tariffs, devaluations, exchange controls, imperial preferences, and other nationally focused measures. The London Economic Conference of 1933 demonstrated that major powers could not agree on a shared recovery strategy.
The Depression weakened democratic governments by destroying jobs and savings, discrediting established parties, making parliamentary compromise difficult, and creating openings for extremist movements. In Germany, pre-existing weaknesses in Weimar democracy combined with financial collapse, austerity, emergency rule, Nazi propaganda, and elite miscalculation to bring Hitler to power.
Next, we examine the ideology that turned Nazi power into a program of expansion, racial hierarchy, and war: how Nazi racial ideology shaped Germany’s aims beyond its borders.
