Jun 28, 2025

Overview

This lecture covers the origins, course, and consequences of World War I, highlighting its global impact, technological innovations, and cultural legacy.

Causes of World War I

  • The assassination of Archduke Franz Ferdinand by Gavrilo Princip triggered a web of alliances into action.
  • Austria issued an ultimatum to Serbia, which led to war declarations involving Russia, Germany, France, Britain, and others.
  • Alliances and beliefs in the glory of war contributed significantly to the escalation.
  • Other interpretations blame Russia’s early mobilization, the rigidity of German planning, or imperialist rivalries.

Course of the War

  • Trench warfare, especially on the Western Front, resulted in stalemate and immense suffering.
  • The war involved global participants, including colonial troops from India, Africa, Australia, New Zealand, and Canada.
  • Early offensives succeeded more on the Eastern Front, where Germany outperformed Russia.
  • Disease killed more soldiers than combat, with dysentery, typhus, cholera, and gangrene widespread.

Technology and Tactics

  • New technologies (tanks, airplanes, poison gas) appeared, but machine guns and barbed wire were most deadly.
  • Outdated tactics, such as infantry charges, led to high casualties.
  • The Battle of the Somme exemplified mass casualties due to modern weaponry.

Soldier Experience

  • Life in the trenches was dominated by fear, poor conditions, and constant shelling.
  • Morale was sustained by camaraderie, duty, fear of punishment, and alcohol.
  • Soldiers received little pay and lived in harsh, unsanitary environments.

Consequences and Legacy

  • The Treaty of Versailles blamed Germany, harming its economy and politics.
  • World War I contributed to the Russian Revolution, leading to Bolshevik rule.
  • The U.S. emerged as a world power, moving from debtor to creditor nation.
  • The Ottoman Empire collapsed, leading to the creation of Turkey.
  • Few colonies gained autonomy despite their contributions to the war.
  • The war produced a sense of disillusionment, seen in “lost generation” literature and a cultural shift toward cynicism.

Key Terms & Definitions
