I. Shifting Power After 1900 (Topic 7.1)

A. Challenges to the established world order

  1. Around 1900, European empires dominated much of Africa and Asia. Industrial strength, modern weapons, overseas investment, and colonial rule supported Western power.

  2. Internal factors weaken a state from within, including unequal landholding, political repression, ethnic tensions, and ineffective reform. External factors include foreign intervention, military defeat, and economic pressure.

  3. These pressures reinforced one another. Defeat could worsen shortages and government debt, while discontent reduced a government's ability to fight or reform.

  4. The Qing, Russian, Ottoman, and Austro-Hungarian empires collapsed early in the century. Most European overseas empires survived the world wars before losing colonies through later decolonization.

B. Russia: from tsarist rule to communist revolution

  1. Russia's tsars exercised autocracy, or rule with few effective constitutional limits. Unequal landholding and poor working conditions created discontent among peasants and industrial workers.

  2. Russia industrialized unevenly. Modern factories existed beside widespread rural poverty, and transportation and military supply systems struggled to meet wartime demands.

  3. Defeat in the Russo-Japanese War (1904–1905) damaged the government's authority. On Bloody Sunday (1905), troops fired on petitioning workers, helping trigger strikes and unrest.

  4. Nicholas II promised civil liberties and an elected Duma, or parliament, but restricted its influence. Limited reform failed to resolve demands for political participation.

  5. World War I brought military defeats, heavy casualties, inflation, and food shortages. In the February Revolution of 1917, strikes and soldiers' refusal to suppress protesters forced the tsar to abdicate.

    a. Russia then used a different calendar; the February Revolution occurred in March by the calendar used in most Western countries.
    b. The Provisional Government continued the war and delayed major land reform, weakening its support.

  6. In the October Revolution of 1917, Vladimir Lenin's Bolsheviks overthrew the Provisional Government. Their promises of peace, land, and bread appealed to soldiers, peasants, and workers.

    a. The October Revolution occurred in November by the Western calendar.
    b. Bolsheviks claimed to build a communist society based on collective ownership of productive resources. In practice, they established centralized one-party rule.

  7. The Treaty of Brest-Litovsk (1918) removed Russia from World War I at the cost of extensive territory. Civil war then pitted the Bolshevik Red Army against varied anti-Bolshevik forces, some supported by foreign powers.

  8. Bolshevik victory produced the Soviet Union (USSR) in 1922. The revolution inspired communist movements abroad and alarmed governments that feared the spread of revolution.

C. China: collapse of the Qing and a fragmented republic

  1. The Qing faced rural hardship, population pressure, rebellion, fiscal weakness, and resentment of Manchu dynastic rule. Earlier wars and unequal treaties had weakened Chinese sovereignty.

  2. Defeats in the Opium Wars and the Sino-Japanese War (1894–1895) expanded foreign influence. Indemnities, territorial losses, and foreign economic privileges undermined confidence in the dynasty.

  3. Reform attempts failed to restore stability. Conservatives stopped the Hundred Days' Reform (1898), while foreign suppression of the Boxer uprising (1899–1901) imposed further costs and humiliation.

  4. The 1911 Revolution began with an uprising at Wuchang and spread as provinces rejected Qing authority. The last emperor abdicated in 1912, ending imperial rule.

  5. Sun Yat-sen promoted nationalism, democracy, and people's livelihood. These principles sought a unified, sovereign republic and improvements in ordinary people's economic security.

  6. Sun transferred the presidency to military leader Yuan Shikai, whose authoritarian rule weakened republican institutions. After Yuan's death in 1916, regional warlords competed for power.

  7. Ending the dynasty did not immediately produce national unity or end foreign influence. Nationalists and communists later offered competing solutions to these problems.

D. Ottoman decline and the emergence of Turkey

  1. The Ottoman Empire faced separatist nationalism, territorial losses, uneven modernization, and European economic influence. Foreign debt gave European creditors leverage over state revenues.

  2. The Young Turk movement restored constitutional government in 1908. Its dominant leaders later centralized power and promoted Turkish nationalism, deepening tensions with some non-Turkish populations.

  3. Losses in the Balkan Wars and defeat in World War I accelerated imperial collapse. Arab revolt, Allied occupation, and plans to divide Ottoman territory weakened the sultan's authority.

  4. Mustafa Kemal Atatürk led Turkish nationalists against occupying forces and the proposed partition of Anatolia. The sultanate was abolished in 1922, and the Republic of Turkey was established in 1923.

  5. Atatürk's reforms strengthened a secular national state. They included European-style civil law, public education, adoption of the Latin alphabet, and expanded legal and political rights for women.

  6. Secularization reduced the authority of religious institutions in government and law. Modernizing reforms operated alongside one-party authoritarian rule rather than full political democracy.

E. The Mexican Revolution

  1. Under Porfirio Díaz, railroads, export production, and foreign investment expanded, but land and wealth remained concentrated. Peasants lost land, workers faced poor conditions, and political opposition was suppressed.

  2. A disputed election and the imprisonment of opposition leader Francisco Madero helped trigger revolution in 1910. Díaz resigned in 1911, but rival revolutionary groups continued fighting.

  3. Emiliano Zapata demanded restoration of village lands in southern Mexico. Pancho Villa led northern revolutionary forces; their priorities differed from those of political leaders seeking a stable central government.

  4. The Constitution of 1917 authorized land reform, strengthened national control over resources, limited Church privileges, and recognized labor protections such as the eight-hour workday and the right to strike.

  5. Reform was uneven and depended on later governments. The party founded in 1929, eventually called the Institutional Revolutionary Party (PRI), incorporated workers and peasants while establishing long-lasting political dominance.

  6. Mexico's revolution challenged landholding and political exclusion without establishing a Soviet-style communist economy. Russia and Mexico both transformed government, but their institutions and economic systems differed.

II. Causes of World War I (Topic 7.2)

A. Imperial rivalry and militarism

  1. Imperialism intensified competition for colonies, strategic routes, resources, and markets. Disputes over Morocco increased tensions between Germany and France and strengthened British cooperation with France.

  2. Germany's growing industrial and naval power challenged Britain's position. The British-German battleship race increased distrust and encouraged military spending.

  3. Militarism gave armed forces and military preparedness high political and cultural importance. Large standing armies, weapons production, and expectations of a short victory made war appear manageable to some leaders.

  4. Mobilization schedules encouraged rapid decisions. Leaders feared that delaying the movement of troops would give opponents an advantage, reducing time for negotiation during a crisis.

B. Nationalism and regional conflicts

  1. Nationalism links political identity to a nation and can support independence, unity, or competition with other nations. It does not always require belief in national superiority, although aggressive forms encouraged hostility.

  2. French resentment over the loss of Alsace-Lorraine to Germany in 1871 contributed to rivalry. German nationalism encouraged demands for greater international power.

  3. Ottoman retreat created instability in the Balkans. Serbia sought influence among South Slavs, Austria-Hungary feared separatism among its own subjects, and Russia claimed a protective role toward Slavic peoples.

  4. Austria-Hungary's annexation of Bosnia-Herzegovina in 1908 angered Serbian nationalists. The Balkan Wars of 1912–1913 further intensified territorial disputes.

C. Alliances and the July Crisis

  1. Before the war, the Triple Alliance joined Germany, Austria-Hungary, and Italy. The Triple Entente linked France, Russia, and Britain through agreements and strategic cooperation.

  2. Alliances were intended to deter attack, but they encouraged leaders to expect outside support. They helped widen the conflict without making every declaration of war automatic or unavoidable.

  3. On June 28, 1914, Bosnian Serb nationalist Gavrilo Princip assassinated Archduke Franz Ferdinand in Sarajevo. Princip belonged to Young Bosnia and received assistance through Serbian nationalist networks.

  4. Germany offered Austria-Hungary strong backing, often called a blank check. Austria-Hungary issued demands to Serbia and declared war on July 28 after rejecting Serbia's response as insufficient.

  5. Russian mobilization in support of Serbia was followed by German declarations of war on Russia and France. Germany's invasion of neutral Belgium helped bring Britain into the war.

  6. Germany's plan for a rapid defeat of France before concentrating on Russia widened an eastern European crisis into a major continental war.

D. From European war to global conflict

  1. The Central Powers included Germany, Austria-Hungary, the Ottoman Empire, and Bulgaria. Italy initially stayed neutral and joined the Allies in 1915.

  2. The Allies included Britain, France, and Russia, later joined by countries including Japan, Italy, and the United States. The wartime coalitions differed from the prewar alliances.

  3. Imperial territories supplied soldiers, workers, food, and materials. Fighting spread to Africa, the Middle East, East Asia, and the Pacific, while naval warfare disrupted global trade.

  4. The assassination was the immediate trigger. Imperial rivalry, militarism, nationalism, regional disputes, and leaders' decisions explain why that trigger produced a much larger war.

III. Conducting World War I (Topic 7.3)

A. Industrial warfare and military stalemate

  1. World War I lasted from 1914 to 1918. Germany's initial advance failed to defeat France quickly, and the Western Front developed into opposing trench systems.

  2. Trench warfare protected soldiers from direct fire but produced a stalemate. Attacks across the exposed ground between trenches faced machine guns, barbed wire, and artillery.

  3. Attrition means wearing down an enemy's manpower and resources. Battles such as Verdun and the Somme in 1916 caused enormous losses without decisive territorial gains.

  4. Artillery caused extensive casualties, while poison gas injured lungs, eyes, and skin. Early tanks could cross obstacles but were unreliable; aircraft expanded reconnaissance and later combat roles.

  5. German U-boats, or submarines, attacked shipping supplying Britain. Britain's naval blockade restricted supplies to Germany and contributed to civilian hunger.

  6. Warfare varied by region. The Eastern Front was more mobile than the Western Front, while the Gallipoli campaign failed to secure an Allied route through the Ottoman straits.

B. Total war and economic mobilization

  1. Total war mobilizes a society's economic, political, and human resources for military victory. World War I extended industrial warfare to factories, farms, transportation networks, and imperial populations on an unprecedented scale.

  2. Governments directed industrial production, purchased military supplies, borrowed through war bonds, raised taxes, and rationed scarce goods. Civilian consumption became subordinate to wartime needs.

  3. Conscription required eligible people to serve in the armed forces. Mass armies increased pressure on households and created labor shortages in civilian industries.

  4. Women entered munitions factories, transportation, agriculture, and nursing in greater numbers. Their contributions strengthened demands for political rights, but employment gains were often restricted after the war.

  5. State power expanded through emergency laws, labor controls, and censorship. In Britain, the Defence of the Realm Act allowed extensive wartime intervention.

C. Propaganda, nationalism, and imperial participation

  1. Propaganda uses selected messages and images to influence attitudes and behavior. Governments appealed to patriotism, duty, fear, and hostility toward enemies to encourage enlistment and sacrifice.

  2. Recruiting posters, war-bond campaigns, newspapers, and films connected individual actions to national survival. Censorship limited information that might weaken morale or expose military plans.

  3. A recruiting poster provides evidence of the behavior officials wanted to encourage. Its message alone does not prove that all viewers supported the war or that its claims were accurate.

  4. British India supplied soldiers and laborers, while France recruited extensively in Africa. African porters carried supplies, often under coercive conditions that caused severe suffering and death.

  5. Troops from Australia, New Zealand, and Canada fought within the British imperial war effort. Chinese laborers supported Allied operations even though they generally served in noncombat roles.

  6. The Arab Revolt of 1916 challenged Ottoman rule with British assistance. Wartime promises of Arab independence later conflicted with British and French territorial arrangements.

D. Turning points and consequences

  1. Germany's renewed unrestricted submarine warfare and the Zimmermann Telegram, which proposed a German-Mexican alliance against the United States, helped bring the United States into the war in April 1917.

  2. Russia's revolutions led to its withdrawal in 1918. Germany shifted troops west, but its final offensives failed, while American troops and Allied resources strengthened the opposing coalition.

  3. Exhaustion, battlefield defeats, shortages, and political unrest undermined the Central Powers. An armistice, or agreement to stop fighting, took effect on November 11, 1918; peace treaties followed later.

  4. Millions of soldiers and civilians died. Survivors faced disability, psychological trauma, displacement, debt, and damaged infrastructure, weakening confidence in prewar ideas of inevitable progress.

  5. The influenza pandemic of 1918–1919 spread through global population movements, including troop transport. It killed tens of millions worldwide and intensified wartime disruption; it was a disease catastrophe rather than a deliberate atrocity.

  6. The war accelerated the fall of the Russian, Austro-Hungarian, and Ottoman empires and encouraged anticolonial expectations. It also strengthened the financial position of the United States relative to indebted European powers.

IV. Economy in the Interwar Period (Topic 7.4)

A. Fragile recovery and the Great Depression

  1. The interwar period (1918–1939) began with war damage, government debt, and disrupted trade. Germany owed reparations, while Allied governments owed wartime debts, especially to the United States.

  2. German hyperinflation in 1923 destroyed the value of money and savings. Reparations conflict, the occupation of the Ruhr, and government money creation contributed to the crisis.

  3. American loans helped stabilize Germany during the mid-1920s, but international recovery became vulnerable to changes in American lending.

  4. The Great Depression followed the 1929 American stock market crash, but the crash was not its only cause. Banking weakness, speculation, unequal purchasing power, agricultural overproduction, and shrinking credit deepened the downturn.

  5. Bank failures reduced savings and lending. Falling demand caused business closures and unemployment, which further reduced spending and created a downward economic cycle.

  6. The crisis spread as American lenders withdrew funds and demand for imports declined. Falling commodity prices hurt export-dependent producers in Latin America, Africa, and Asia.

  7. Protectionism uses tariffs and other restrictions to protect domestic producers. Retaliatory tariffs reduced international trade and worsened difficulties for countries dependent on exports.

B. Democratic reform and the New Deal

  1. Governments increasingly challenged laissez-faire, the idea that markets should operate with limited state intervention. Economic crisis encouraged public spending, financial regulation, and social assistance.

  2. Economist John Maynard Keynes argued that inadequate overall spending could prolong unemployment. Government borrowing and spending could support demand when private investment was weak.

  3. President Franklin D. Roosevelt's New Deal, beginning in 1933, combined relief for people in need, recovery measures, and reforms intended to reduce future instability.

    a. Public works programs, including the Civilian Conservation Corps and Works Progress Administration, provided employment and built infrastructure.
    b. Deposit insurance helped restore confidence in banks. Social Security established old-age benefits and unemployment protections.

  4. The New Deal expanded federal responsibility while retaining private property, competitive elections, and a market economy. Its policies overlapped with Keynesian ideas but did not form a single fully Keynesian program.

  5. Recovery remained incomplete and unequal. Reduced spending contributed to renewed recession in 1937–1938, while wartime mobilization later brought a much larger expansion of production and employment.

C. Soviet central planning and repression

  1. During the Russian Civil War, War Communism included grain requisitioning and state control of industry. War destruction and coercive policies contributed to economic breakdown and unrest.

  2. Lenin's New Economic Policy (NEP), introduced in 1921, restored limited private trade and small business while leaving major industries and banks under state control.

  3. After consolidating power following Lenin's death, Joseph Stalin replaced the NEP with compulsory economic transformation. Five-Year Plans, beginning in 1928, set state production targets.

  4. A command economy directs production through government planning rather than primarily through market prices. Soviet planners prioritized steel, coal, machinery, and electricity over consumer goods.

  5. Collectivization forced peasants into large collective farms. Officials sought grain for cities and exports while bringing rural society under tighter political control.

    a. The regime labeled many opponents kulaks, supposedly wealthy peasants, and confiscated property or deported them.
    b. Resistance, livestock destruction, disruption of farming, and coercive grain seizures contributed to catastrophic famine.

  6. Industrial output increased rapidly, helping create a major industrial power, but official targets encouraged distorted reporting and sacrificed living standards. Forced labor, famine, imprisonment, and executions imposed enormous human costs.

  7. Stalin's purges eliminated real and imagined rivals. The Gulag system used prisoners for labor and reinforced political repression.

D. Fascist intervention and Latin American economic nationalism

  1. Fascist governments retained much private ownership while directing business and labor toward national goals. Rearmament and public works created jobs while preparing for expansionist war.

  2. Mussolini's corporatism organized employers and workers into state-supervised bodies. Independent unions and strikes were suppressed, so official claims of class cooperation concealed unequal political power.

  3. In Mexico, Lázaro Cárdenas redistributed land to peasant communities and nationalized foreign-owned oil holdings in 1938. Nationalization transfers private assets to state ownership; PEMEX became the national oil company.

  4. In Brazil, Getúlio Vargas promoted industry, labor protections, and state investment. His Estado Novo, established in 1937, combined economic modernization with censorship and authoritarian rule.

  5. Import-substitution industrialization encouraged domestic production of goods previously imported. Tariffs and state investment aimed to reduce dependence on foreign manufactures and unstable export markets.

  6. New Deal reform, fascist direction, Soviet planning, and Latin American economic nationalism all expanded state intervention. They differed sharply in ownership, political rights, coercion, and the groups receiving benefits.

V. Unresolved Tensions After World War I (Topic 7.5)

A. Peace settlements and their contradictions

  1. At the Paris Peace Conference of 1919, victorious leaders sought competing goals. Wilson promoted a new international order, France prioritized security against Germany, and Britain sought security alongside economic recovery and imperial interests.

  2. Wilson's Fourteen Points included more open diplomacy, national self-determination, and an international peace organization. Self-determination means that a people should have a meaningful role in deciding its political status.

  3. The Treaty of Versailles (1919) required Germany to surrender colonies and territory, accept military restrictions, and pay reparations. Its war-responsibility clause became a major source of German resentment.

  4. New or enlarged states, including Poland, Czechoslovakia, and Yugoslavia, replaced parts of defeated empires. Their boundaries still contained ethnic minorities, so creating nation-states did not eliminate nationalist tensions.

  5. The League of Nations sought collective security, in which states cooperate against aggression. It lacked its own military and depended on members' willingness to act; American refusal to join weakened its authority.

B. Imperial continuity and the mandate system

  1. Most British, French, Dutch, Belgian, and Portuguese colonies remained under imperial rule between the wars. The collapse of several land empires did not immediately end overseas colonialism.

  2. Mandates placed former German and Ottoman territories under victorious powers with League supervision and an official promise of preparation for self-government. In practice, the arrangement often continued colonial domination.

  3. Britain and France gained control over former Ottoman Arab territories. Britain administered Iraq and Palestine, including Transjordan's distinct administration, while France administered Syria and Lebanon.

  4. Former German colonies were redistributed. Britain and France divided authority over Togo and Cameroon, while Britain administered Tanganyika and other powers received additional territories.

  5. Wartime promises and agreements conflicted. The Sykes-Picot Agreement (1916) anticipated British and French influence, while British correspondence with Arab leaders had encouraged expectations of Arab independence.

  6. The Balfour Declaration (1917) supported a national home for the Jewish people in Palestine while stating that existing non-Jewish communities' civil and religious rights should not be prejudiced. Conflicting national claims and British administration contributed to later tensions.

C. Resistance to colonial rule

  1. Wartime service, economic hardship, and unmet promises strengthened anticolonial movements. Self-determination was applied selectively, encouraging activists to challenge the gap between imperial rhetoric and practice.

  2. The Indian National Congress became a mass movement against British rule. The Rowlatt Acts and the Amritsar massacre (1919) deepened opposition to repression.

  3. Mohandas Gandhi promoted nonviolent resistance and civil disobedience, the deliberate refusal to obey unjust laws. Boycotts of British textiles linked everyday consumption to the independence struggle.

  4. The Salt March (1930) challenged the British salt monopoly and tax. By turning a necessity into a symbol of colonial injustice, the campaign broadened participation and attracted international attention.

  5. Constitutional reforms expanded provincial self-government but retained British control over crucial central powers. Disagreements about minority representation also grew; the Muslim League under Muhammad Ali Jinnah advanced demands that later contributed to partition in 1947.

  6. In French West Africa, strikes, political associations, and congresses opposed forced labor, unequal treatment, and colonial exploitation. Resistance also included wartime uprisings such as the Volta-Bani revolt (1915–1916).

  7. The March First Movement (1919) demanded Korean independence from Japan. Japanese repression showed the limits of applying postwar self-determination to colonized peoples.

D. Chinese nationalism and Japanese expansion

  1. China's May Fourth Movement (1919) protested the decision to transfer Germany's Shandong rights to Japan rather than restore them directly to China. It linked opposition to foreign domination with demands for cultural and political renewal.

  2. The Kuomintang (Nationalist Party) sought national unity and stronger government. After Sun Yat-sen's death, Chiang Kai-shek led the party and turned against its former communist allies in 1927.

  3. The Chinese Communist Party, founded in 1921, gained rural support through promises of land reform. The Long March (1934–1935) was a costly retreat that strengthened Mao Zedong's leadership.

  4. Japan's military seized Manchuria in 1931, using the staged Mukden Incident as a pretext. It established Manchukuo, a puppet state nominally led by former Qing emperor Puyi.

  5. Japanese expansion sought resources, markets, and strategic security. Japan left the League in 1933 after criticism of its actions and began full-scale war against China in 1937.

  6. Japan's later Greater East Asia Co-Prosperity Sphere promised Asian liberation from Western empires. In practice, occupation imposed Japanese domination, resource extraction, forced labor, and violence.

VI. Causes of World War II (Topic 7.6)

A. Fascism, dictatorship, and economic crisis

  1. Fascism promoted extreme nationalism, authoritarian leadership, militarism, and suppression of political opponents. Fascists rejected liberal democracy and Marxist class conflict while promising national renewal.

  2. Benito Mussolini became Italy's prime minister in 1922 and consolidated dictatorship. Disappointment with postwar territorial gains and fear of socialism helped him attract support.

  3. Adolf Hitler became German chancellor in 1933 and dismantled democratic government. The Depression weakened faith in the Weimar Republic and increased support for extremist alternatives.

  4. Nazism combined fascist politics with racial hierarchy, antisemitism, and territorial conquest. Antisemitism is hostility or discrimination directed against Jews.

  5. Totalitarianism describes efforts to control political life and much of society through a single party, propaganda, surveillance, and terror. Nazi Germany and Stalin's USSR shared repressive methods despite opposing ideologies and different economic systems.

  6. Economic distress helped dictators gain support but did not make war inevitable. Expansionist ideology, military institutions, elite cooperation, and specific decisions converted crises into aggression.

B. Expansion and the failure of collective security

  1. Hitler sought to overturn Versailles, unite German-speaking populations, and conquer Lebensraum, or living space, in eastern Europe. This program involved dispossession, racial domination, and destruction of existing states.

  2. Germany expanded its military and remilitarized the Rhineland in 1936, violating treaty restrictions. Limited foreign opposition encouraged further risks.

  3. Italy invaded Ethiopia in 1935. Weak and incomplete League sanctions failed to stop conquest, demonstrating the limits of collective security.

  4. The Spanish Civil War (1936–1939) internationalized ideological conflict. Germany and Italy aided Franco's Nationalists, while the USSR and international volunteers supported the Republican side.

  5. Japan's conquest in China demonstrated that imperial expansion threatened peace outside Europe as well. Economic needs and military leaders' growing influence reinforced expansionist policies.

C. Appeasement and the outbreak of war

  1. Appeasement grants concessions in the hope of avoiding war. British and French leaders feared another devastating conflict, faced economic and military limits, and sometimes viewed revision of Versailles as reasonable.

  2. Germany annexed Austria in the Anschluss (1938). At the Munich Conference (1938), Britain and France accepted German annexation of Czechoslovakia's Sudetenland without Czechoslovak participation in the decision.

  3. Germany's occupation of the remaining Czech lands in March 1939 showed that Hitler's ambitions extended beyond uniting German-speaking people. Britain and France then guaranteed support for Poland.

  4. The Nazi-Soviet Pact (August 1939) promised nonaggression and secretly divided parts of eastern Europe into spheres of influence. It reduced Hitler's immediate fear of a two-front war.

  5. Germany invaded Poland on September 1, 1939. Britain and France declared war on September 3; the USSR invaded eastern Poland later that month.

  6. War in Asia had already expanded with Japan's 1937 invasion of China. The European date of 1939 should not obscure the earlier Asian conflict.

D. The Pacific crisis and global consequences

  1. Japanese expansion into China and Indochina brought American and other restrictions on strategic supplies, including oil. Japanese leaders chose further conquest rather than abandon their imperial objectives.

  2. Japan attacked Pearl Harbor on December 7, 1941, while launching attacks across the Pacific and Southeast Asia. It sought to weaken American interference with expansion toward resource-rich territories.

  3. American entry, followed by German and Italian declarations of war against the United States, connected major theaters into a wider global struggle.

  4. World War II ultimately devastated Europe and Asia, weakened European empires, and strengthened the United States and USSR. Their later rivalry and postwar decolonization are developed further in Unit 8.

VII. Conducting World War II (Topic 7.7)

A. Strategies, theaters, and turning points

  1. The Axis powers centered on Germany, Italy, and Japan. The major Allied powers included Britain, the USSR, the United States, and China, joined by many other countries.

  2. German blitzkrieg, or lightning war, coordinated aircraft, tanks, and mobile ground forces to break defenses quickly. Germany defeated Poland in 1939 and France in 1940.

  3. During the Battle of Britain (1940), British air defense, supported by radar and coordinated fighter control, prevented Germany from gaining the air superiority needed for invasion.

  4. Germany invaded the USSR in Operation Barbarossa (1941). Vast distances, supply problems, Soviet resistance, and harsh conditions helped stop a quick victory.

  5. Stalingrad (1942–1943) severely weakened Germany's eastern campaign. El Alamein (1942) helped reverse Axis advances in North Africa, while Midway (1942) reduced Japan's offensive carrier strength.

  6. Allied island-hopping captured selected Pacific positions while bypassing others, cutting supply routes and establishing bases closer to Japan. Aircraft carriers and submarines became crucial naval weapons.

  7. D-Day (June 6, 1944) opened a major western front in Normandy. Allied advances from the west and Soviet advances from the east culminated in Germany's surrender in May 1945.

B. Mobilization in democratic states

  1. Under Winston Churchill, Britain used rationing, conscription, industrial direction, and broadcast speeches to sustain resistance. Women served in war industries, agriculture, and military support services.

  2. Under Franklin Roosevelt, the United States converted factories to military production, financed war through taxes and bonds, and rationed consumer goods. Lend-Lease, beginning in 1941, supplied Allied countries before direct American entry.

  3. Posters, radio, newspapers, and films presented civilian work and sacrifice as essential to victory. Rosie the Riveter symbolized women's industrial labor, although racial and gender discrimination continued.

  4. Britain and the United States retained important representative institutions, but wartime powers curtailed freedoms. The United States forcibly removed and incarcerated about 120,000 people of Japanese ancestry, most of them American citizens.

  5. Wartime restrictions therefore complicate claims that democratic mobilization fully protected individual rights. Political systems differed, but democratic governments also committed serious abuses.

C. Mobilization in totalitarian and imperial states

  1. Nazi Germany used propaganda, censorship, racial ideology, and terror to demand loyalty. Forced laborers from occupied territories, prisoners of war, and concentration camp inmates supported its economy.

  2. Stalin's government directed Soviet production, relocated factories away from advancing German forces, and appealed to patriotism as well as communist ideology. State repression continued through imprisonment and forced population transfers.

  3. Japan demanded loyalty to the emperor and portrayed conquest as Asian liberation. Occupied populations faced coercive labor, food requisitioning, and violent repression.

  4. European empires mobilized colonial resources and troops. The British Indian Army recruited about 2.5 million volunteers, and African soldiers supported British and French forces.

  5. Wartime service did not remove colonial inequalities. Britain's imprisonment of leaders during the Quit India movement (1942) showed that Allied claims to defend freedom coexisted with imperial repression.

  6. All major powers directed resources and shaped public opinion. Totalitarian governments more systematically eliminated opposition, employed pervasive terror, and sought enduring control over public and private life.

D. Technology and the targeting of civilians

  1. Radar improved detection of aircraft and ships. Codebreaking, mechanized transport, long-range aircraft, aircraft carriers, and industrial supply systems shaped military effectiveness.

  2. Strategic bombing attacked industry, transport, and cities to weaken an enemy's war capacity and morale. Germany's Blitz against Britain and Allied raids on Germany inflicted extensive civilian casualties.

  3. Firebombing used incendiary weapons to create widespread fires. Raids on Hamburg, Dresden, and Tokyo demonstrated the vulnerability of densely populated cities.

  4. The American Manhattan Project developed atomic weapons. The United States bombed Hiroshima on August 6, 1945, and Nagasaki on August 9, causing immediate destruction and later deaths from injuries and radiation.

  5. Soviet entry into the war against Japan in August 1945 also undermined Japanese strategic options. Japan announced surrender on August 15 and formally signed it on September 2.

  6. Historians debate the relative influence of the atomic attacks, Soviet intervention, blockade, and other pressures on surrender. A single-cause explanation oversimplifies the final decision.

E. Outcomes of total war

  1. World War II killed tens of millions, with civilian deaths exceeding military deaths. Occupation, genocide, bombing, forced labor, famine, and disease expanded destruction beyond battlefields.

  2. The USSR and China suffered especially severe losses. Cities, farms, and transport systems were destroyed, and millions became refugees or displaced persons.

  3. The United Nations (1945) replaced the League as the central international peace organization. Its Security Council gave major victorious powers permanent seats and veto authority.

  4. Occupations, war-crimes trials, and reconstruction reshaped defeated states. Europe’s weakened position accelerated challenges to colonial rule and the emergence of a new international balance.

VIII. Mass Atrocities After 1900 (Topic 7.8)

A. Causes and distinctions

  1. Genocide involves acts committed with intent to destroy, in whole or in part, a national, ethnic, racial, or religious group. Not every civilian death or instance of mass violence meets this specific definition.

  2. Ethnic cleansing aims to remove a population from an area through coercion or violence. It can involve genocide, but forced removal and intent to destroy are distinct concepts.

  3. Extremist ideologies identified groups as racial, ethnic, political, or religious enemies. Dehumanization portrayed victims as less than human, helping perpetrators justify persecution.

  4. War and civil conflict weakened safeguards, expanded emergency powers, and provided opportunities for organized killing. Bureaucracies, transport systems, propaganda, and local collaborators could turn prejudice into coordinated destruction.

  5. Violence depended on political choices and institutions, not simply on timeless ethnic hatred. Perpetrators exploited existing tensions, constructed enemies, and organized participation.

B. The Armenian genocide

  1. During World War I, Ottoman leaders portrayed Armenian Christians as an internal security threat, especially amid conflict with Russia. Wartime fears combined with exclusionary nationalism and earlier persecution.

  2. Beginning in 1915, authorities organized mass arrests, deportations, death marches, and killings. Deportees faced deliberate deprivation of food and protection, causing enormous loss of life.

  3. The destruction of Armenian communities illustrates how state power and wartime accusations of disloyalty could enable genocide. Ottoman Armenians should not be treated collectively as responsible for military collaboration.

  4. Survivors formed diaspora communities, while dispossession and denial shaped long-term memory and political conflict. The Turkish government's denial does not make the genocide merely an unresolved difference of opinion.

C. The Holocaust

  1. The Holocaust was the Nazi-led systematic persecution and murder of approximately six million European Jews. Antisemitic racial ideology was central to Nazi policy.

  2. Persecution escalated through exclusion from jobs and public life, the Nuremberg Laws (1935), and Kristallnacht (1938), a coordinated wave of anti-Jewish violence.

  3. During the war, Jews were confined in overcrowded ghettos, subjected to deprivation, and deported. After the invasion of the USSR, mobile killing units carried out mass shootings.

  4. The Final Solution organized the murder of Europe's Jews. The Wannsee Conference (1942) coordinated implementation among officials after mass killing had already begun.

  5. Killing centers such as Treblinka and Auschwitz-Birkenau used gas chambers and other methods of murder. Railways, administrative records, confiscation of property, and collaboration helped sustain the process.

  6. The Nazis also persecuted and murdered Roma and Sinti, disabled people, Polish civilians, Soviet prisoners of war, political opponents, and others. Their targeting involved related but distinct policies.

  7. Jewish resistance included armed uprisings, escape, underground organization, and preservation of cultural and religious life. The Warsaw Ghetto Uprising (1943) is one example of resistance under extreme constraints.

  8. The Holocaust destroyed communities, displaced survivors, and strengthened demands for human-rights protections and accountability for state-organized crimes.

D. Stalinist mass violence and Japanese wartime atrocities

  1. In the Holodomor (1932–1933), millions died in Soviet Ukraine. Forced collectivization, grain confiscation, punitive measures, and restrictions on movement intensified famine.

  2. Ukraine's catastrophe occurred within a broader Soviet famine that also devastated other regions. Many countries recognize the Holodomor as genocide; historians debate aspects of intent and classification while documenting the state's central responsibility.

  3. Stalinist purges, deportations, executions, and forced labor targeted perceived political opponents and entire populations. Their consequences included death, family separation, fear, and destruction of local institutions.

  4. During the Nanjing Massacre (1937–1938), Japanese troops murdered large numbers of Chinese civilians and disarmed soldiers and committed widespread sexual violence.

  5. Japanese occupation also imposed brutal forced labor and military sexual slavery on women from Korea and other occupied territories. Imperial claims of liberation concealed racial hierarchy and coercion.

E. Later genocides and ethnic violence

  1. In Cambodia (1975–1979), Pol Pot's Khmer Rouge forcibly emptied cities and imposed an agrarian communist program. Executions, starvation, overwork, and persecution killed roughly a quarter of the population.

    a. The regime targeted supposed class enemies, intellectuals, religious communities, and minorities. Ethnic Vietnamese and Cham Muslims experienced genocidal persecution.
    b. Vietnam's invasion removed the regime from power in 1979, but survivors faced prolonged displacement and trauma.

  2. In Rwanda (1994), Hutu extremists organized genocide against the Tutsi and murdered Hutu who opposed them. Colonial racial classification, discriminatory politics, civil war, and organized propaganda contributed to the crisis.

    a. Radio broadcasts and local administrative networks helped identify victims and mobilize killers. Approximately 800,000 people were killed over about 100 days.
    b. The Rwandan Patriotic Front ended the genocide through military victory. International failure to stop the killing and later refugee movements had major regional consequences.

  3. During the Bosnian War (1992–1995), nationalist forces used forced removal, detention, sexual violence, and mass killing. Bosnian Serb forces murdered more than 8,000 Bosniak men and boys at Srebrenica in 1995, an act recognized as genocide by international courts.

  4. These post-1945 cases belong to the unit's broader period of 1900 to the present. They show that defeat of the Axis did not end genocide or prevent the use of state institutions against targeted populations.

F. Consequences and international responses

  1. Mass atrocities produce demographic loss, displacement, destroyed cultural institutions, contested memory, and trauma across generations. They also reshape property ownership, political authority, and relations between communities.

  2. The Nuremberg trials prosecuted major Nazi leaders and advanced accountability for war crimes and crimes against humanity. Later tribunals prosecuted crimes committed in Rwanda and the former Yugoslavia.

  3. The Genocide Convention (1948) established an international obligation to prevent and punish genocide. The Universal Declaration of Human Rights (1948) asserted broad rights belonging to all people.

  4. Recognition of rights did not guarantee enforcement. State sovereignty, geopolitical interests, weak intervention, and denial repeatedly limited international protection.

IX. Causation in Global Conflict (Topic 7.9)

A. Explaining interacting causes

  1. Long-term conditions create vulnerability, while immediate triggers start a particular crisis. The Sarajevo assassination triggered World War I within an existing system of imperial rivalry, nationalism, and military competition.

  2. A complete explanation connects causes rather than merely listing them. Serbian nationalism threatened Austria-Hungary, Russian support widened the confrontation, and German planning brought France and Belgium into the conflict.

  3. World War II grew from unresolved settlements and economic crisis, but expansionist regimes actively chose conquest. Nazi racial imperialism and Japanese ambitions explain why discontent produced specific military objectives.

  4. Economic crisis had different outcomes in different states. The United States expanded democratic reform, while Germany moved toward dictatorship and rearmament; institutions, leadership, and political coalitions shaped these differences.

B. Technology, state power, and imperial change

  1. Industrial technology increased destructive capacity, but political decisions determined its use. Factories supplied weapons, railways moved armies, and governments organized populations to sustain prolonged conflict.

  2. Total war expanded state authority and blurred distinctions between military and civilian targets. World War II intensified these patterns through aerial destruction, occupation, and systematic mass murder.

  3. Internal grievances and external shocks combined in imperial collapse. Russian inequality and autocracy predated 1914, but wartime defeats and shortages turned chronic discontent into revolutionary crisis.

  4. Nationalism could sustain empires' war efforts, inspire independence movements, or justify exclusion and conquest. Its effects depended on who defined the nation and how leaders treated outsiders and minorities.

  5. The world wars weakened European power while mobilizing colonial populations. Continued imperial control after 1918 encouraged further resistance, and the costs of the second war strengthened later independence movements.

C. Using evidence and evaluating arguments

  1. Assess relative significance by explaining which cause most directly shaped an outcome and how other causes enabled it. A claim about militarism should connect weapons, planning, or military influence to a specific decision or result.

  2. Compare sources according to purpose, audience, point of view, and historical situation. A state production report may reveal official priorities while hiding shortages, coercion, or falsified output.

  3. Propaganda and political speeches are evidence of intended persuasion, not reliable measurements of unanimous belief. Compare them with civilian accounts, laws, economic records, and evidence of resistance.

  4. Distinguish correlation from causation. Rising unemployment and extremist voting may be connected, but an explanation must show how insecurity, party organization, propaganda, and elite decisions translated distress into political power.

  5. Qualify broad claims with relevant differences. Both world wars mobilized imperial populations, but Japanese conquest in Asia, the Holocaust, and atomic bombing give World War II distinct causes, methods, and consequences.
