European History – 1890 to 1945

💣European History – 1890 to 1945 Unit 6 – Paris Peace Conference & Interwar Era

The Paris Peace Conference reshaped Europe after World War I, with the Treaty of Versailles imposing harsh penalties on Germany. The Big Four - Wilson, Lloyd George, Clemenceau, and Orlando - redrew borders, created new nations, and established the League of Nations to maintain peace. The interwar era saw economic turmoil, the rise of fascism and communism, and social changes like women's suffrage. Despite hopes for lasting peace, the treaty's shortcomings and growing nationalism laid the groundwork for future conflicts, ultimately leading to World War II.

Key Players and Their Aims

  • Woodrow Wilson (United States) advocated for self-determination, open diplomacy, and a League of Nations to prevent future wars
  • David Lloyd George (Great Britain) sought to maintain British naval supremacy and secure German reparations while preserving the balance of power in Europe
  • Georges Clemenceau (France) aimed to punish Germany, secure French borders, and obtain reparations to rebuild France after the war
  • Vittorio Orlando (Italy) wanted to gain territory promised by the Allies in the Treaty of London (1915) and establish Italy as a major power
    • Sought control over the Adriatic Sea and the port city of Fiume
  • Japan aimed to retain control over former German colonies in the Pacific and expand its influence in Asia
  • Smaller nations and colonies sought self-determination and independence from imperial powers

The Big Four and Treaty of Versailles

  • The Treaty of Versailles was signed on June 28, 1919, between Germany and the Allied Powers (France, Great Britain, United States, and Italy)
  • The treaty placed sole responsibility for the war on Germany (Article 231, the "war guilt" clause) and imposed harsh penalties
    • Germany lost 13% of its territory and 10% of its population to neighboring countries
    • The Rhineland was demilitarized, and the German army was limited to 100,000 men
    • Germany was prohibited from having an air force, submarines, or tanks
  • Germany was required to pay reparations to the Allied Powers, initially set at 132 billion gold marks (later reduced)
  • The treaty also established the League of Nations, an international organization designed to promote peace and resolve disputes between nations
  • The United States Senate ultimately rejected the Treaty of Versailles and did not join the League of Nations

Redrawing the Map of Europe

  • New countries were created from the former Austro-Hungarian Empire: Austria, Hungary, Czechoslovakia, and Yugoslavia
  • Poland was reconstituted as an independent state, with access to the Baltic Sea through the Polish Corridor
  • Romania gained territory from Hungary (Transylvania) and Russia (Bessarabia)
  • The Baltic states of Estonia, Latvia, and Lithuania gained independence from Russia
  • Germany lost territory to France (Alsace-Lorraine), Belgium (Eupen-Malmedy), Denmark (Northern Schleswig), and Poland (West Prussia and Posen)
  • The Ottoman Empire was partitioned, with France and Great Britain gaining mandates over Syria, Lebanon, Iraq, and Palestine
  • The Sykes-Picot Agreement (1916) between France and Great Britain divided the Middle East into spheres of influence

Economic Consequences and Reparations

  • The war left many European countries with massive debts, high inflation, and weakened economies
  • Germany faced hyperinflation in the early 1920s due to the burden of reparations and the French occupation of the Ruhr
    • The German mark became virtually worthless, leading to economic and social instability
  • The Dawes Plan (1924) and the Young Plan (1929) attempted to restructure German reparations payments
  • The United States provided loans to European countries to help rebuild their economies (e.g., the Dawes Plan)
  • The global economic interdependence created by the war and its aftermath contributed to the spread of the Great Depression in the 1930s

League of Nations: Hopes and Realities

  • The League of Nations was established to promote international cooperation, peace, and security
  • The League had a General Assembly, where all member states were represented, and a Council, which included permanent members (Great Britain, France, Italy, and Japan) and non-permanent members
  • The League lacked its own military force and relied on member states to enforce its decisions
  • Successes of the League included settling border disputes (e.g., between Sweden and Finland), organizing humanitarian aid, and establishing the Permanent Court of International Justice
  • Failures of the League included its inability to prevent the Japanese invasion of Manchuria (1931), the Italian invasion of Ethiopia (1935), and the German remilitarization of the Rhineland (1936)
  • The absence of major powers like the United States and the Soviet Union weakened the League's effectiveness

Rise of Nationalism and New Political Ideologies

  • The aftermath of World War I saw the rise of nationalism and new political ideologies across Europe
  • Fascism emerged in Italy under Benito Mussolini, who promised to restore Italian greatness and establish a strong, centralized state
    • Fascism emphasized nationalism, authoritarianism, and opposition to communism and liberalism
  • Nazism, a form of fascism, rose in Germany under Adolf Hitler and the National Socialist German Workers' Party (NSDAP)
    • Nazism added elements of racism, antisemitism, and expansionism to fascist ideology
  • Communism gained support in Russia, leading to the Russian Revolution (1917) and the establishment of the Soviet Union
  • Authoritarian regimes emerged in several European countries, such as Spain under Francisco Franco and Portugal under António de Oliveira Salazar

Social and Cultural Changes in the 1920s

  • The 1920s saw significant social and cultural changes, particularly in the United States and Western Europe
  • Women gained more independence and political rights, including the right to vote in many countries (e.g., the 19th Amendment in the United States)
  • The "Roaring Twenties" in the United States were characterized by economic prosperity, consumerism, and new forms of entertainment (e.g., jazz, radio, and cinema)
  • Art movements such as Surrealism, Dadaism, and Expressionism challenged traditional artistic conventions
  • The "Lost Generation" of writers, including Ernest Hemingway and F. Scott Fitzgerald, captured the disillusionment and alienation felt by many after the war
  • Technological advancements, such as the widespread use of automobiles and electricity, transformed daily life

Seeds of Future Conflict

  • The Treaty of Versailles left many nations feeling resentful and unsatisfied, particularly Germany, which viewed the treaty as a "diktat" (dictated peace)
  • The failure to address the principle of self-determination in many regions (e.g., the Sudetenland, Danzig) created tensions among ethnic minorities
  • Economic instability and the Great Depression contributed to the rise of extremist political movements and authoritarian regimes
  • The League of Nations' inability to effectively resolve disputes and prevent aggression undermined its credibility and encouraged nations to pursue their own interests
  • The policy of appeasement adopted by Western powers towards aggressive actions by Germany, Italy, and Japan emboldened these nations to pursue further expansionism
  • The ideological divide between fascism and communism, as well as the competing ambitions of nations, set the stage for the outbreak of World War II in 1939
