7.4 Appeasement and European Responses to Fascism

As fascism spread across Europe in the 1930s, nations faced a central question: how do you stop aggressive, expansionist regimes without triggering another catastrophic war? The strategies they tried, from diplomatic concessions to collective security pacts, each failed in different ways. Understanding why they failed is one of the most important lessons of this period.

Appeasement gave Nazi Germany time and territory to grow stronger. The League of Nations lacked the teeth to enforce its resolutions. And by the time countries scrambled to rearm and form new alliances, the balance of power had already shifted decisively toward the fascist states.

European Responses to Fascism

Diplomatic Strategies

European nations pursued several distinct diplomatic approaches to the fascist threat, though none proved sufficient on its own.

• Appeasement, pursued primarily by Britain and France, aimed to avoid war by making diplomatic concessions to aggressive nations. The logic was that satisfying "reasonable" demands would remove the motivation for conflict.
• Collective security, embodied in the League of Nations, sought to maintain peace through international cooperation and mutual defense. The idea was that an attack on one member would provoke a unified response from all.
• The Soviet Union initially pursued collective security, signing mutual assistance pacts with France and Czechoslovakia. But after being excluded from the Munich negotiations in 1938, Stalin shifted course and signed the Molotov-Ribbentrop Pact with Nazi Germany in August 1939, a non-aggression agreement that stunned the world.
• Some nations formed regional alliances to counter fascist threats. The Little Entente (Czechoslovakia, Romania, Yugoslavia) and the Polish-Romanian Alliance of 1921 were attempts by smaller states to protect themselves through mutual defense.

Military Preparedness

As appeasement's failure became clearer in the late 1930s, rearmament became urgent.

• Britain initiated a rapid military buildup, including the Shadow Factories scheme, which secretly converted civilian factories for wartime production. The RAF's expansion during this period proved critical in the coming air war.
• France invested heavily in the Maginot Line, a massive fortification system along its eastern border with Germany. The line was technologically impressive but reflected a defensive mindset, and it did not extend along the Belgian border, which is exactly where Germany attacked in 1940.
• Smaller nations like Czechoslovakia strengthened border defenses and expanded conscription, though these efforts were undermined when the Munich Agreement handed their fortified Sudetenland to Germany without a fight.

Neutrality Efforts

Not every country chose sides. Several pursued neutrality, though with varying degrees of success.

• Switzerland reinforced its long-standing armed neutrality, mobilizing reserves and preparing for potential invasion while maintaining its diplomatic position.
• Sweden maintained official neutrality but quietly assisted Finland during the Winter War (1939-40) against the Soviet Union, showing how neutrality often had limits in practice.
• Spain under Franco remained officially neutral despite its ideological alignment with fascism and the military aid Germany and Italy had provided during the Spanish Civil War (1936-39). Franco's decision to stay out of World War II was driven more by Spain's exhaustion after its own civil war than by principle.

Appeasement: Motivations and Consequences

Driving Factors

Appeasement wasn't simply cowardice. British and French leaders had real reasons for pursuing it, even if those reasons look badly mistaken in hindsight.

• Memory of World War I loomed over everything. That war killed roughly 10 million soldiers and left a generation traumatized. Political leaders and the public alike were desperate to avoid a repeat.
• Economic weakness mattered too. Both Britain and France were still recovering from the Great Depression and were not confident they could afford or sustain another major war.
• Sympathy for German grievances played a role. Many in Britain believed the Treaty of Versailles had been too harsh, and that Germany had legitimate claims to territories with ethnic German populations.
• Fear of communism led some Western leaders to view Nazi Germany as a useful buffer against Soviet expansion. This made them more willing to tolerate Hitler's actions than they might otherwise have been.

Territorial Concessions

Appeasement produced a series of escalating concessions, each of which made the next one harder to resist.

• Rhineland (1936): Hitler remilitarized the Rhineland in direct violation of the Treaty of Versailles. France and Britain protested but took no action. Hitler later admitted his forces would have retreated if France had responded militarily.
• Anschluss (1938): Germany annexed Austria in March 1938 with minimal international resistance. Hitler framed it as a unification of German-speaking peoples, and many Austrians initially welcomed it.
• Munich Agreement (1938): The most infamous act of appeasement. Britain's Neville Chamberlain and France's Édouard Daladier agreed to let Germany annex the Sudetenland, a heavily fortified, industrially valuable region of Czechoslovakia. Chamberlain returned to London declaring he had achieved "peace for our time." Within six months, Germany occupied the rest of Czechoslovakia.
• Memel (1939): Germany pressured Lithuania into surrendering the Memel Territory in March 1939, just days after occupying the remainder of Czechoslovakia.

Policy Outcomes

• Each concession emboldened Hitler, confirming his belief that Britain and France would not fight.
• Germany used the time and territory gained to strengthen its military and industrial capacity. The Czech arms factories alone were a major strategic gain.
• Appeasement eroded trust in British and French leadership among smaller Eastern European nations, which increasingly felt they could not rely on Western guarantees.
• The policy shifted the balance of power decisively toward the fascist states, making the eventual war larger and more destructive than it might have been if aggression had been confronted earlier.

Collective Security vs. Fascist Aggression

League of Nations Limitations

The League of Nations was designed to prevent future wars through collective action and diplomatic resolution. In theory, it was a powerful idea. In practice, it had fatal weaknesses.

• The League lacked enforcement mechanisms. It could issue condemnations and impose economic sanctions, but it had no military force to back up its decisions.
• The absence of key powers crippled it from the start. The United States never joined (despite President Wilson's role in creating it), and Germany and the Soviet Union were members only intermittently.
• Japan's invasion of Manchuria (1931) was the first major test. The League condemned the invasion; Japan simply withdrew from the League and kept Manchuria.
• Italy's conquest of Ethiopia (1935-36) was even more damaging. The League imposed limited sanctions on Italy, but they excluded oil (the resource Italy needed most), and member states did not enforce them consistently. Ethiopian Emperor Haile Selassie's plea to the League became a symbol of the institution's failure.

Collective Security Efforts

Several alliances attempted to fill the gap the League could not.

• The Stresa Front (1935), formed by Britain, France, and Italy, aimed to oppose German rearmament. It collapsed within months when Britain signed a separate naval agreement with Germany and Italy invaded Ethiopia.
• The Franco-Soviet Treaty of Mutual Assistance (1935) was meant to deter German aggression, but France never developed concrete military plans to implement it, limiting its deterrent value.
• The Little Entente (Czechoslovakia, Romania, Yugoslavia) tried to counter revisionist powers in Central Europe but lacked the military strength to stand up to Germany alone.
• These collective efforts proved short-lived and ineffective because the major powers were unwilling to commit the military force needed to back them up.

Consequences of Failure

• The League's inability to stop the Rhineland remilitarization in 1936 confirmed that collective security was effectively dead as a strategy.
• Faith in international institutions collapsed, replaced by bilateral agreements and power politics.
• An environment of mistrust and insecurity spread across Europe. Smaller nations could no longer trust that international agreements would protect them, pushing some toward accommodation with Germany.

Fascist Expansionism and the Balance of Power

Territorial Changes

Each act of fascist expansion shifted the strategic map of Europe.

• The Rhineland remilitarization (1936) allowed Germany to fortify its western border, making a future French attack far more costly and undermining France's ability to aid its Eastern European allies.
• The Anschluss (1938) added Austria's population and resources to Germany and placed German forces on the borders of Czechoslovakia, Hungary, and Italy.
• The occupation of Czechoslovakia (1938-39) gave Germany the Škoda Works, one of Europe's largest arms manufacturers, along with significant industrial capacity and fortified territory.
• Italy's invasion of Albania (April 1939) extended fascist influence into the Balkans and gave Mussolini a staging ground across the Adriatic.

Strategic Realignments

• The Molotov-Ribbentrop Pact (August 1939) was the most dramatic realignment. Nazi Germany and the Soviet Union, bitter ideological enemies, agreed to non-aggression and secretly divided Eastern Europe into spheres of influence. This freed Hitler to invade Poland without fear of a two-front war.
• The Axis alliance between Germany, Italy, and later Japan created a powerful bloc challenging the existing European order. The Anti-Comintern Pact (1936, expanded 1937) had already formalized their anti-communist coalition before full military alliance followed.
• Britain and France responded by issuing guarantees to Poland in March 1939, finally drawing a line. But without Soviet cooperation, enforcing that guarantee was extremely difficult.

Consequences for European Powers

• France's security was deeply undermined. German rearmament and expansion neutralized the Maginot Line's strategic value and left France's eastern allies exposed.
• Britain's position was threatened in the Mediterranean and Middle East by Italian aggression, stretching its imperial commitments thin.
• Smaller nations in Eastern Europe found themselves caught between German and Soviet pressure, with no reliable great-power protector. The Baltic states, Poland, Romania, and others faced impossible choices.
• Fascist expansionism ultimately made World War II inevitable. By September 1939, when Germany invaded Poland, the diplomatic and military options for preventing a general European war had been exhausted.
