World War I: Causes and Mood of 1914

Growing International Conflict

• Mounting tensions arose in Europe in the early 20th century because of nationalism, imperial rivalries, militarization, and an entangled alliance system.
• National pride and the competition for global empires increased mistrust among major powers.
• The Triple Alliance of Germany, Austria-Hungary, and Italy and the Triple Entente comprised of France, Russia, and Britain formed two hostile blocs.
• Germany's naval buildup and France's focus on military preparedness exemplified militarism, which further destabilized peace.
• A small regional conflict in the Balkans had the potential to trigger a broader war because of this volatile environment.
• The assassination of Archduke Franz Ferdinand sparked a chain reaction that resulted in war.

The Mood of 1914

• Patriotic enthusiasm, militarism, and national pride gripped Europe in 1914.
• The public largely welcomed the idea of war, viewing it as an opportunity for heroism and national renewal.
• Intellectuals, journalists, and politicians romanticized war as a unifying and purifying experience.
• Many Europeans believed the conflict would be brief and decisive, especially in Germany and France.
• The deadly power of modern weapons and the complexity of alliance commitments were ignored in this optimism.
• The idealistic mood quickly turned to horror as trench warfare and mass slaughter defined the war.

The Outbreak of War

• World War I was triggered by the assassination of Archduke Franz Ferdinand of Austria-Hungary in Sarajevo in June 1914, by a Serbian nationalist.
• Austria issued an ultimatum to Serbia, and when Serbia failed to meet all demands, Austria declared war.
• Russia mobilized in defense of Serbia, prompting Germany to declare war on Russia and France.
• Britain entered the war when Germany invaded neutral Belgium.
• The rigid alliance system and rapid military mobilizations escalated what could have been a localized conflict into a full-scale continental war.
• The war began with a deadly momentum few could stop.

Stalemate and Slaughter on the Western Front

• The Western Front became a grueling stalemate characterized by trench warfare after Germany's initial Schlieffen Plan failed.
• Millions of casualties resulted in massive battles, such as Verdun and the Somme in 1916, with little territorial gain.
• Soldiers faced constant artillery bombardments, machine-gun fire, and poison gas while living in horrific conditions.
• The war of attrition demoralized troops and civilians alike as death counts soared without decisive results.
• New technologies made defense stronger than offense, trapping both sides in a deadly, static conflict.

The Widening War

• World War I quickly grew into a global conflict.
• The Ottoman Empire joined the Central Powers, while Japan and eventually the United States joined the Allies.
• European colonies in Africa and Asia were drawn in, supplying soldiers and resources.
• T.E. Lawrence, a British officer, led Arab revolts against Ottoman rule in the Middle East.
• Germany's policy of unrestricted submarine warfare antagonized neutral nations, especially the U.S., which entered the war in 1917 after the sinking of the Lusitania and the Zimmermann Telegram.
• These developments brought new energy to the war but also increased its scale and devastation.

Mobilizing for Total War

• World War I required the complete mobilization of societies.
• Governments took control of economies, rationed food, regulated labor, and converted industries to wartime production.
• Propaganda became essential to maintain morale and support for the war effort.
• Civilian freedoms were limited in belligerent nations like Britain, France, and Germany, as censorship and conscription expanded.
• Women entered the workforce in unprecedented numbers to replace men at war, gaining temporary new roles and responsibilities.
• Total war blurred the line between the home front and battlefront, transforming society fundamentally.

The Social Impact

• The war had deep social consequences.
• The influx of women into factories and public service challenged traditional gender roles and laid the groundwork for women’s suffrage in many countries after the war.
• The working class gained leverage due to labor shortages and increased union activity.
• Widespread death and economic hardship also fueled resentment and despair.
• Returning soldiers struggled to reintegrate into civilian life, and many societies became polarized between conservatives fearing revolution and leftists demanding change.
• The war fundamentally altered class structures and public expectations, setting the stage for postwar unrest.

Growing Political Tensions

• Political tensions grew within the warring states as the war dragged on.
• Food shortages, inflation, and staggering casualties led to discontent among soldiers and civilians alike.
• Strikes and protests erupted across Europe, and antiwar sentiments spread among socialists and pacifists.
• Support for the war waned in Germany and Austria-Hungary, especially among ethnic minorities and left-wing groups.
• These pressures pushed governments toward greater repression and political instability.
• The Russian Empire, already weakened by internal unrest, collapsed under the weight of war and revolution.

The Fall of Imperial Russia

• Russia’s involvement in World War I proved disastrous, as military defeats and economic collapse led to widespread discontent.
• The February Revolution in March 1917 forced Tsar Nicholas II to abdicate, ending centuries of Romanov rule.
• Soldiers mutinied, workers went on strike, and the Duma (parliament) formed a Provisional Government.
• The collapse of the tsarist regime was fueled by poor leadership, food shortages, and a lack of reform.
• The monarchy’s fall opened the door for radical political change and marked the beginning of the first successful communist revolution.

The Provisional Government

• A liberal Provisional Government under Alexander Kerensky attempted to establish democracy in Russia after the tsar’s abdication.
• It failed to address the major issues facing the country: land reform, peace, and food shortages.
• It chose to continue fighting in World War I, a deeply unpopular decision.
• The Petrograd Soviet, a council of workers and soldiers, rivaled the Provisional Government’s authority.
• This "dual power" situation created chaos, allowing the Bolsheviks, a radical Marxist faction led by Lenin, to gain popular support
• The Bolsheviks ultimately overthrew the government later that year.

Lenin and the Bolshevik Revolution

• Vladimir Lenin returned to Russia in April 1917 with German help, promoting radical slogans like "Peace, Land, and Bread."
• He denounced the Provisional Government and gained support among workers, peasants, and soldiers through the Bolsheviks' promises.
• The Bolsheviks, led by Lenin and aided by Leon Trotsky, staged a coup d’état in October 1917, overthrowing the Provisional Government in the October Revolution.
• The Bolsheviks seized power in Petrograd with little resistance, establishing a dictatorship that promised Soviet control.
• The Bolsheviks quickly consolidated authority under one-party rule, laying the foundation for communist rule in Russia.

Trotsky and the Seizure of Power

• Leon Trotsky, a key Bolshevik leader, played a decisive role in organizing the October Revolution.
• Trotsky coordinated the armed takeover of government buildings and communication centers as head of the Petrograd Soviet and the Military-Revolutionary Committee.
• His leadership and charisma helped the Bolsheviks gain control without mass bloodshed.
• The Bolsheviks moved quickly to dismantle the old regime, withdrawing from World War I through the harsh Treaty of Brest-Litovsk in 1918.
• The Bolshevik seizure of power sparked a civil war between Reds (Bolsheviks) and Whites (counterrevolutionaries).

Dictatorship and Civil War

• Following their seizure of power, the Bolsheviks, now calling themselves Communists, faced fierce resistance from monarchists, liberals, and foreign powers.
• The Russian Civil War (1918–1922) was brutal and divisive.
• The Red Army, under Trotsky, defeated the poorly coordinated White forces using superior organization and ruthless tactics.
• The Bolsheviks implemented "war communism," seizing grain and nationalizing industry to support the war effort, leading to famine and hardship.
• The victory of the Reds solidified Bolshevik control but at the cost of millions of lives and widespread devastation.

The End of the War

• World War I ended in November 1918 after years of bloodshed and exhaustion.
• The Allies countered a failed German offensive in 1918 with the Hundred Days Offensive, bolstered by fresh American troops.
• Germany agreed to an armistice on November 11 because mutinies and revolution were occurring at home.
• The Central Powers collapsed, the Austro-Hungarian Empire dissolved, and Ottoman and German monarchies fell.
• The war left Europe deeply scarred and economically weakened, with millions dead and wounded and widespread social upheaval that would shape the postwar order.

Revolution in Austria-Hungary and Germany

• Internal revolts shattered the Austro-Hungarian and German Empires as defeat loomed.
• Nationalist movements broke away in Austria-Hungary, forming new nations like Czechoslovakia and Yugoslavia.
• Sailors mutinied in Kiel in Germany, and widespread unrest led to the abdication of Kaiser Wilhelm II in November 1918.
• The Weimar Republic was proclaimed, but its birth was marred by instability, revolution, and bitterness over the war’s outcome.
• These revolutions marked the definitive end of Europe's old monarchies and the beginning of a volatile democratic experiment in Germany.

The Treaty of Versailles

• The Treaty of Versailles (1919) officially ended World War I and imposed harsh penalties on Germany.
• The treaty’s “war guilt clause” blamed Germany for the war and demanded reparations, territorial losses like Alsace-Lorraine, and severe military restrictions.
• The League of Nations was created to maintain peace, though the U.S. did not join.
• The treaty also redrew Europe’s borders, creating new states from former empires.
• Germans saw it as a national humiliation, sowing the seeds of resentment that would fuel World War II, while the Allies viewed it as justice.

The Peace Settlement in the Middle East

• The postwar peace reshaped the Middle East under European mandates.
• Britain and France divided former Ottoman territories under the Sykes-Picot Agreement, establishing control over regions like Iraq, Syria, and Palestine.
• These mandates were justified as temporary oversight, but in reality, they were colonial.
• Promises made to Arabs during the war—like independence—were broken, leading to growing nationalist resentment.
• The Balfour Declaration, supporting a Jewish homeland in Palestine, further complicated the region, laying the groundwork for future Arab-Israeli conflict.

The Human Costs of the War

• World War I caused unprecedented human suffering.
• Approximately 10 million soldiers died, and over 20 million were wounded, often with lifelong injuries.
• Civilian deaths from starvation, disease, and violence also surged.
• Survivors suffered from trauma, later called “shell shock” (now PTSD).
• Entire regions were devastated economically and physically.
• Disillusionment permeated society, giving rise to a “lost generation” of intellectuals and veterans who questioned traditional values.
• The war marked a profound psychological break from the 19th-century world, ushering in a new era of skepticism and radical thought.

Modern Philosophy

• European intellectuals reevaluated traditional beliefs, giving rise to existentialism and modern philosophy in the interwar period.
• Thinkers like Friedrich Nietzsche influenced a generation of philosophers who questioned religion, progress, and rationality.
• Existentialists like Jean-Paul Sartre and Albert Camus emphasized individual meaning in a chaotic world.
• Logical positivism, championed by Ludwig Wittgenstein, argued that only statements verifiable by logic or observation were meaningful.
• This intellectual crisis reflected the postwar disillusionment and the collapse of Enlightenment-era optimism.

The Revival of Christianity

• Some Europeans turned back to religion in response to modern despair.
• The interwar years saw a modest revival of Christianity, especially among intellectuals who sought moral clarity.
• Thinkers like Karl Barth emphasized human sinfulness and the need for divine grace, rejecting liberal theology.
• Writers such as Jacques Maritain promoted a return to traditional faith and ethics in Catholic circles.
• Religion re-entered cultural conversations as a counterweight to growing secularism and nihilism, though church attendance did not universally increase.

The New Physics

• Physics underwent a revolution in the early 20th century that undermined traditional scientific certainties.
• Albert Einstein’s theory of relativity challenged Newtonian physics by showing that time and space were relative, not absolute.
• Max Planck’s quantum theory introduced the idea that energy is emitted in discrete packets, disrupting classical physics.
• Niels Bohr’s model of the atom and Werner Heisenberg’s uncertainty principle further emphasized the unpredictability of the physical world.
• These discoveries contributed to a broader cultural shift toward skepticism and anxiety about the reliability of human knowledge and progress.

Freudian Psychology

• Sigmund Freud’s theories radically changed understandings of the human mind.
• He emphasized the unconscious, where repressed desires and traumatic memories shaped behavior.
• Freud introduced concepts like the id, ego, and superego, and he argued that human actions were often driven by irrational forces.
• His ideas about sexuality, repression, and childhood experiences challenged Victorian norms and influenced art, literature, and popular culture.
• Freudian psychology became a cornerstone of 20th-century thought, reflecting the postwar belief in deep-seated human irrationality.

Architecture and Design

• Interwar Europe saw modernist movements in architecture and design that emphasized function, simplicity, and new materials.
• The Bauhaus school in Germany, led by Walter Gropius, promoted unadorned, geometric structures and the integration of art and industry.
• Architects like Le Corbusier embraced functionalism, believing buildings should serve the needs of society.
• Modernist architecture rejected ornamentation in favor of clean lines and efficiency, symbolizing a break with prewar aesthetic traditions and aligning with broader calls for social reform and rational planning.

New Artistic Movements

• Dadaism rejected logic and reason, favoring absurdity and protest against traditional values.
• Surrealism, led by André Breton and influenced by Freud, explored dreams and the unconscious.
• Expressionists like Edvard Munch and post-impressionists like Pablo Picasso used bold colors and distorted forms to express emotion.
• These movements challenged the boundaries of art and reflected a disillusioned, fragmented worldview shaped by war and instability.

Twentieth-Century Literature

• Literature in the 1920s and 1930s became more experimental and introspective.
• Writers like James Joyce (Ulysses), Virginia Woolf, and Marcel Proust used stream-of-consciousness techniques to explore the inner thoughts of characters.
• T.S. Eliot’s The Waste Land and Franz Kafka’s surreal, nightmarish works reflected the postwar sense of alienation and cultural decay.
• Themes of meaninglessness, existential doubt, and the collapse of traditional values dominated modernist literature, capturing the psychological toll of war and modern life.

Modern Music

• Radio had become central to everyday life by the 1930s, offering news, music, drama, and political speeches.
• Governments used radio for propaganda, Franklin Roosevelt’s “fireside chats” in the U.S. and Hitler’s broadcasts in Nazi Germany showed how leaders could speak directly to citizens.
• Radio fostered a new sense of national unity and immediacy, dramatically altering communication and public discourse.

Germany and the Western Powers

• Postwar Germany was politically and economically unstable.

• The Locarno Treaties normalized relations between Germany and Western powers, while Germany’s entry into the League of Nations in 1926 signaled a return to international cooperation.
• The Kellogg-Briand Pact of 1928, signed by over 60 nations, renounced war as a tool of policy.
• These diplomatic initiatives reflected widespread desire to avoid another global conflict and offered temporary hope for a stable European order, though ultimately ineffective.

Hope in Democratic Government

• During the 1920s, many Europeans believed liberal democracy could bring stability and progress.
• Democratic governments emerged in Germany, Czechoslovakia, and parts of Eastern Europe.
• Women gained suffrage in several countries.
• Social reforms expanded education and workers’ rights.
• Democracy remained fragile in many regions, especially where economic hardship and political polarization weakened public faith in liberal institutions.
• The Great Depression soon tested the strength of democratic systems across Europe.

The Economic Crisis

• The Great Depression began in 1929 with the U.S. stock market crash and quickly spread worldwide.
• Global trade collapsed, industrial production declined, and unemployment soared.
• Germany and Austria were hit especially hard due to their dependence on American loans.
• The depression discredited capitalist economies and liberal democracies in the eyes of many Europeans.
• Political extremism gained ground as people turned to radical solutions, fascism, communism, and authoritarianism, to address mass suffering and instability.

Mass Unemployment

• Unemployment became a defining crisis of the 1930s.
• Joblessness reached over 25% in Germany and the U.S.
• The unemployed faced poverty, homelessness, and despair.
• Governments struggled to provide relief, and traditional economic theories failed to explain or resolve the downturn.
• This social catastrophe radicalized politics, leading to increased support for parties promising strong action, such as the Nazis in Germany and socialists in other regions.
• The crisis exposed the weaknesses of unregulated capitalism and fueled demand for state intervention.

The New Deal in the United States

Conservative Authoritarianism and Radical Totalitarian Dictatorships

• Authoritarianism reemerged in different forms in the interwar period.
• Conservative regimes in Eastern Europe preserved traditional hierarchies.
• Radical totalitarian states, like Nazi Germany and the Soviet Union, sought total control over society.
• Totalitarianism involved mass propaganda, a single-party system, repression, and the use of terror to achieve ideological goals.
• These regimes promised order and unity amid chaos, appealing to populations disillusioned with democracy and economic failure.

Communism and Fascism

• Communism and fascism were both totalitarian ideologies but differed fundamentally.
• Communism, as practiced in the USSR, sought a classless society through the abolition of private property and state ownership of the economy.
• Fascism, seen in Italy and Germany, glorified nationalism, militarism, and a strong leader, rejecting democracy and socialism.
• Both ideologies used violence, censorship, and propaganda to maintain control.
• Their rise was fueled by the failures of liberal democracies and the trauma of war and depression.

From Lenin to Stalin

• Joseph Stalin emerged as Soviet leader after Lenin’s death in 1924 by outmaneuvering rivals like Trotsky.
• Stalin abandoned Lenin’s NEP in favor of rapid industrialization and central planning.
• He consolidated power through party loyalty, purges, and a personality cult.
• Stalin’s rise marked a shift from revolutionary idealism to dictatorial control, transforming the Soviet Union into a powerful but repressive state.
• His policies aimed to modernize Russia but resulted in immense human suffering.

The Five-Year Plans

• Stalin launched the Five-Year Plans to industrialize the Soviet Union rapidly.
• The first plan (1928–1932) emphasized heavy industry, collectivized agriculture, and state quotas.
• While industrial output soared, collectivization caused massive disruption in the countryside.
• Millions of peasants died due to famine—especially during the Ukrainian Holodomor—and violent repression.
• The USSR became an industrial power at immense human and social cost, reinforcing Stalin’s authoritarian rule.

Life and Culture in Soviet Society

• Soviet life under Stalin was shaped by propaganda, censorship, and strict control.
• Education promoted communist ideology, while the arts served state goals through socialist realism.
• Religion was suppressed, and family life was shaped by state policies on gender and work.
• Some citizens benefitted from industrial jobs, education, and social mobility, despite repression.
• Fear permeated society, as deviation from the party line could lead to punishment or death.

Stalinist Terror and the Great Purges

• Stalin consolidated power through widespread terror.

• Mussolini’s alliance with Hitler later drew Italy into World War II.

The Roots of National Socialism in Germany

• National Socialism (Nazism) emerged in Germany amid postwar humiliation, economic collapse, and fear of communism.
• Adolf Hitler joined the Nazi Party and promoted a radical ideology based on racism, anti-Semitism, nationalism, and anti-communism.
• The Nazis promised to restore German pride and overturn the Treaty of Versailles.
• Their appeal grew as Weimar democracy faltered, especially after the Great Depression, which devastated Germany’s economy and fueled extremism.

Hitler’s Road to Power

• Fear, coercion, and propaganda shaped public life, but some genuinely admired Hitler’s leadership and vision.
• This support was built on exclusion and violence against minorities, political enemies, and dissenters.

Aggression and Appeasement

• Hitler defied the Treaty of Versailles in the 1930s by rearming Germany, remilitarizing the Rhineland, and annexing Austria and the Sudetenland.
• Western powers, especially Britain and France, followed a policy of appeasement, hoping to avoid another war.
• The 1938 Munich Agreement symbolized this strategy, granting Hitler territorial gains in exchange for peace.
