Cambridge International AS Level International History 1871-1945 Notes

International Relations in an Age of Imperialism 1871–1918

  • Definition of Imperialism: The policy of extending a nation’s power by gaining political and economic control over more territory. This is sometimes referred to as colonialism.
  • General Characteristics of the 1871–1914 Wave:     * Focused primarily on Africa and Asia due to mineral supplies and trade opportunities in the crumbling Chinese Empire.     * A real attempt was made to prevent rivalry from leading to open warfare (e.g., Treaty of Berlin 18851885).     * The USA and Japan emerged as new imperial powers alongside European nations.

The ‘Scramble for Africa’

  • Chronological Shift: In 18711871, only 10%10\% of Africa was under direct European control; by 19001900, over 90%90\% was colonised.
  • Causes of the Scramble:     * Strategic Factors: Britain gained control of Cape Colony and the Suez Canal (opened 18691869) to protect trade routes to India. British administration of Egypt began in 18821882.     * Medical Advancement: The discovery of quinine by French scientists in 18171817 provided an effective treatment for malaria, reducing deaths in the ‘Dark Continent’.     * Weaponry: Fast-firing rifles, machine guns, and heavy artillery gave Europeans a military advantage over native populations.     * Political Factors: European borders were settled by 18711871; expansion could only occur overseas to increase prestige.     * Abolition of the Slave Trade: Businessmen sought new forms of trade after slavery was abolished.     * Industrial Revolution: Need for raw materials and new markets for manufactured goods. Developments in steamships allowed navigation of the Congo, Zambezi, and Niger rivers.     * Sense of Duty: Belief in racial superiority and a duty to bring ‘commerce, Christianity, and civilisation’ (David Livingstone’s ‘three Cs’).
  • Motive of Major Powers:     * Britain: Focused on East Africa (Egypt, Sudan, Kenya, Uganda, etc.). Ambition of Cecil Rhodes: a railway from Cairo to Cape Town. Controlled 30%30\% of Africa's population.     * France: Active in the West and North-West (Senegal, Algeria) seeking raw materials like palm oil and timber.     * Belgium: King Leopold II claimed the Congo basin, exploiting it for ivory and rubber through a regime of cruelty.     * Germany: Entered in 18811881; took Kamerun, German East Africa, South West Africa, and Togoland. Costs often exceeded the value of the colonies.
  • The Treaty of Berlin (18851885):     * Designed to regulate colonisation. Terms: inform others of claims; demonstrate ‘effective occupation’; free passage on Niger and Congo rivers; abolition of slavery.     * Fashoda Incident (18981898): A clash in Sudan between French (Major Marchand) and British (Lord Kitchener) forces. Resolved via compromise: France took Morocco; Britain took Egypt and Sudan.
  • The Boer Wars:     * First Boer War (1880811880\text{–}81): Boers in the Transvaal rebelled against British rule; the British were defeated. Pretoria Convention (18811881) gave Boers self-governing status.     * Second Boer War (189919021899\text{–}1902): Triggered by gold discoveries and the failed Jameson Raid (18951895). Kruger (Transvaal President) vs. the British.     * Outcome: British victory (Treaty of Vereeniging, 19021902). Cost: 22,00022,000 British deaths, 30,00030,000 civilian deaths in concentration camps, and over 200million200\,\text{million} pounds.
  • Effects on Africa: Efficient administration and transport systems were balanced against the arbitrary drawing of borders (splitting ethnic groups like the Maasai and Chewa) and extreme exploitation (mutilation and forced labour in the Congo).

The Emergence of the USA and Japan as World Powers

  • USA Imperialism:     * Isolationism: Traditional 19th-century policy of avoiding alliances and international commitments.     * Monroe Doctrine (18231823): Stated the USA would not interfere in Europe, and European intervention in the Americas would be seen as aggression.     * Economic Growth: By 19001900, the USA was outstripping rivals in coal (238million tonnes238\,\text{million tonnes}), pig iron (14.5million tonnes14.5\,\text{million tonnes}), and steel (12million tonnes12\,\text{million tonnes}).     * Spanish–American War (18981898): Triggered by the explosion of the battleship Maine in Havana. Resulted in US control of Cuba, the Philippines, Puerto Rico, and Guam.     * Theodore Roosevelt: Supported Panama Canal (opened 19141914), the Platt Amendment (19031903) for control of Cuba, and the Roosevelt Corollary (19041904) to act as an international police power.
  • Japan Imperialism:     * Modernisation: The Meiji government (18671867) centralised power and industrialised (Mitsubishi shipyards). Compulsory military service was introduced.     * War with China (1894951894\text{–}95): Japan gained Formosa and Port Arthur (Treaty of Shimonoseki).     * Triple Intervention: France, Russia, and Germany forced Japan to hand over Port Arthur to Russia.     * Russo–Japanese War (1904051904\text{–}05): Surprise attack on Port Arthur. Battle of Tsushima (19051905) destroyed the Russian fleet. Treaty of Portsmouth recognized Japan's rights in Korea.

International Relations in an Age of Extremism 1919–39

  • Mussolini’s Italy:     * Rise to Power: Post-war disappointment, inflation (lira fell from 55 to 2828 per dollar), and fear of communism led to the March on Rome (19221922).     * Styles: Totalitarianism, Autarky, and Extreme Nationalism.     * Foreign Policy: Early diplomacy (Locarno, 19251925) gave way to aggression. Invasion of Abyssinia (19351935) and formation of the Rome–Berlin Axis (19361936).

  • United Nations:     * Origins: Atlantic Charter (19411941), Dumbarton Oaks (19441944), Yalta (19451945), and the San Francisco Conference (19451945).     * Differences from League: Decisions in Assembly/Council no longer require total unanimity (two-thirds majority allowed); USA and USSR were members from the beginning.

Questions & Discussion

  • Q: What does the Treaty of Brest-Litovsk suggest about Germany’s attitude towards Wilson’s Fourteen Points in March 19181918?     * A: It suggests Germany completely ignored Wilsonian ideals of self-determination and fairness, imposing an extremely vindictive peace that prioritized territorial and industrial gains.
  • Q: Why did many of Hitler’s generals concern themselves with his foreign policy actions in 19391939?     * A: They believed Germany was not yet ready for a major war against the combined strength of Britain and France, and that Hitler was pushing his luck too far with Poland.
  • Q: How justified were German objections to the Treaty of Versailles?     * A: While the terms were harsh (reparations, land loss), historians note they were less severe than what Germany imposed on Russia at Brest-Litovsk, and Germany remained the strongest economic power in Europe.
  • Q: What was the significance of the 7 December 19411941 attack?     * A: The Japanese attack on Pearl Harbor killed 24022402 men and destroyed 190190 aircraft, ending US isolationism and globalizing WWII.
