World History Final Second Semester

🌍 1. Age of Imperialism (c. 1850–1914)

Definition:

The Age of Imperialism was a period in which powerful nations, particularly European countries, extended their control over weaker territories across the globe, primarily in Africa, Asia, and the Pacific. This control was often political, economic, and cultural.

Causes:

  • Economic: Industrialized nations needed raw materials (rubber, oil, cotton) and new markets to sell manufactured goods.

  • Political: Nations wanted to assert power and prestige by acquiring colonies. Competition for dominance was fierce among European powers.

  • Social: Beliefs like the "White Man’s Burden" and Social Darwinism justified imperial conquest by claiming it was the duty of the "superior" races to civilize the "inferior."

  • Technological: Advances in weaponry, steamships, and medicine (like quinine for malaria) made imperial expansion possible.

Key Events:

  • Scramble for Africa: European countries rapidly colonized African territories. The Berlin Conference (1884-85) regulated this to avoid conflict among Europeans.

  • British Raj in India: British control brought infrastructure and modernization but also economic exploitation and social upheaval.

  • China: The Opium Wars led to the establishment of spheres of influence where European powers controlled trade.

  • U.S. Imperialism: The U.S. acquired the Philippines, Guam, Puerto Rico, and built the Panama Canal, signaling a shift toward global influence.

Effects:

  • Exploitation of resources and labor in colonized regions.

  • Suppression of local cultures and resistance movements.

  • Rise of nationalist movements that would later push for independence.

  • Heightened tensions among imperial powers, contributing to WWI.

💥 2. World War I (1914–1918)

Causes (M.A.I.N.):

  • Militarism: Nations built up massive militaries and glorified war.

  • Alliances: Secret and public alliances (Triple Entente: France, Britain, Russia vs. Triple Alliance: Germany, Austria-Hungary, Italy) pulled many nations into the conflict.

  • Imperialism: Competition for colonies created rivalries.

  • Nationalism: Ethnic groups sought independence; countries pursued national prestige.

  • Immediate Cause: The assassination of Archduke Franz Ferdinand by a Serbian nationalist in Sarajevo triggered the war.

Major Events:

  • Trench Warfare: Dominated the Western Front; conditions were horrific and deadly.

  • Key Battles: Somme and Verdun in the west; Gallipoli in the east.

  • New Technologies: Tanks, poison gas, machine guns, airplanes, and submarines increased the scale of death.

End of the War:

  • The U.S. entered in 1917 after the Lusitania sinking and the Zimmermann Telegram.

  • Germany signed an armistice on November 11, 1918.

Treaty of Versailles (1919):

  • Blamed Germany for the war (war guilt clause).

  • Germany had to pay heavy reparations, reduce its military, and lose territory.

  • League of Nations was formed to prevent future wars, but it lacked power.

  • Treaty bred resentment in Germany, laying the groundwork for WWII.

🛠 3. Interwar Period (1919–1939)

Economic:

  • Great Depression: Began in 1929; caused massive unemployment, poverty, and global trade decline.

  • Weakened democratic governments and increased popularity of extremist solutions.

Political:

  • Rise of Totalitarian Regimes:

    • Italy: Mussolini established the first fascist regime, emphasizing nationalism and militarism.

    • Germany: Hitler rose to power, promising to overturn the Treaty of Versailles and restore German pride.

    • USSR: Stalin ruled with an iron fist, using purges, censorship, and propaganda.

    • Japan: Military leaders expanded into Asia, invading Manchuria and China.

Social:

  • Growing discontent with postwar treaties.

  • Appeasement policies, particularly by Britain and France, failed to check aggression (e.g., allowing Hitler to annex Austria and Sudetenland).

  • League of Nations proved ineffective in stopping conflicts.

⚔ 4. World War II (1939–1945)

Causes:

  • Harsh terms of the Treaty of Versailles

  • Economic instability from the Great Depression

  • Policy of appeasement

  • Aggressive expansion by Germany, Italy, and Japan

Major Aggressions:

  • Germany: Invaded Poland on Sept. 1, 1939, triggering WWII.

  • Blitzkrieg: "Lightning war" strategy using fast, overwhelming attacks.

  • Axis Powers: Germany, Italy, Japan.

  • Allied Powers: UK, USSR, U.S., China, and others.

Key Events:

  • Battle of Britain: Air war where Britain resisted German bombing.

  • Operation Barbarossa: Germany's invasion of the USSR in 1941; failed to take Moscow.

  • Pearl Harbor: Japan attacked the U.S. on Dec. 7, 1941; U.S. declared war.

  • D-Day (June 6, 1944): Allied forces landed in Normandy, opening a Western Front.

  • Holocaust: Nazi genocide of 6 million Jews and millions of others, including Roma, disabled, and political prisoners.

  • Battle of Dunkirk: Evacuation of British and Allied troops from France between May 26 and June 4, 1940, marking a significant turning point in World War II.

  • Battle of Stalingrad: Major confrontation between German and Soviet forces from August 23, 1942, to February 2, 1943, resulting in a devastating defeat for the Germans and marking a turning point in the Eastern Front.

War in the Pacific:

  • Island Hopping: U.S. strategy to reach Japan by capturing key islands.

  • Battle of Midway (1942): Turning point in the Pacific War.

  • Atomic Bombs: Hiroshima (Aug 6) and Nagasaki (Aug 9, 1945).

End of WWII:

  • V-E Day (May 1945): Victory in Europe after Hitler’s suicide and Germany's surrender.

  • V-J Day (Aug 1945): Victory over Japan after atomic bombings.
