Causes of World War I

Overview

  • Focus on four main causes: Militarism, Alliances, Imperialism, and Nationalism.
  • Each cause contributed to the complex situation in Europe leading to the outbreak of World War I.

Militarism

  • Definition: Belief in building strong militaries and using them aggressively.
  • Context: Industrial manufacturing increased weapon production and lethality.
  • Germany's Role: Rapid industrialization and military buildup, leading to a powerful military force.
    • Concerns: France felt threatened due to comparatively weak military.
    • Great Britain: Maintained a strong military but at high national resource cost.

Alliances

  • Early 20th Century: Balance of power through two major alliances:
    • Triple Alliance: Germany, Italy, Austro-Hungarian Empire.
    • Triple Entente: Britain, France, Russia.
  • Purpose: National security and isolation of rivals.
  • Impact: Led to military mobilization plans that were difficult to stop once initiated.
    • Railroads played a crucial role in troop mobilization.

Imperialism

  • Historical Context: Marked by European imperial expansion.
  • Germany’s Influence: Sought to expand empire, increasing competition and conflict.
    • Colonial Conflicts: Led to creation and strengthening of alliance systems.

Nationalism

  • Definition: Emphasis on national glory and unity, with rival states seen as enemies.
  • Impact: Promoted belief that national identity was paramount and under threat.
    • Result: Conflicts were met with force rather than compromise.

The Spark: Assassination in the Balkans

  • Event: Serbian nationalist Gavrilo Princip assassinated Archduke Franz Ferdinand of Austro-Hungarian Empire.
  • Consequences:
    • Nationalistic retaliation by Austro-Hungarians.
    • Alliance System Activation: Serbian alliance with Russia and Austro-Hungarian alliance with Germany escalated the conflict.
    • Led to a broader mobilization and the onset of World War I.

Conclusion
