The First World War

🟢 Share on WhatsApp
Chapter in a nutshell: World War I (1914–1918) grew from nationalism, imperialism, militarism (arms race) and a rigid system of alliances; the assassination of Archduke Franz Ferdinand (1914) was the spark. The Allies defeated the Central Powers; the harsh Treaty of Versailles (1919) punished Germany and the League of Nations was formed — but the bitterness sowed seeds of World War II.

1. Causes of World War I

Nationalism

  • Aggressive national pride and rival claims, especially in the Balkans ("powder keg of Europe").

Imperialism

  • Fierce competition for colonies/markets in Asia and Africa bred Anglo-German and other rivalries.

Militarism / Armament Race

  • A naval and military arms race (Germany vs Britain; the Dreadnought battleships); huge standing armies created a sense of an inevitable war.

System of Alliances

BlocMembers
Triple AllianceGermany, Austria-Hungary, Italy
Triple EntenteBritain, France, Russia
- Alliances meant a local quarrel could drag all of Europe into war.

Immediate Cause

  • The assassination of Archduke Franz Ferdinand (heir to Austria-Hungary) at Sarajevo (28 June 1914) by a Serbian → Austria attacked Serbia → alliances pulled in the great powers.

2. Course of the War (1914–1918)

  • Central Powers (Germany, Austria-Hungary, Turkey) vs the Allies (Britain, France, Russia, later Italy and the USA, 1917).
  • Marked by trench warfare, new weapons (machine guns, tanks, poison gas, aircraft, submarines).
  • Russia withdrew after its 1917 Revolution; the USA's entry (1917) tilted the balance to the Allies; Germany surrendered → war ended 11 November 1918.

3. Consequences

  • Treaty of Versailles (1919): harsh on Germany — war-guilt clause, heavy reparations, loss of territory and colonies, army limited → deep German resentment.
  • League of Nations founded to keep peace.
  • Fall of empires (German, Austro-Hungarian, Russian, Ottoman); new nations emerged.
  • Enormous loss of life and economic ruin; USA emerged as a world power.
  • The bitterness fed the rise of dictatorships (Hitler, Mussolini) → World War II.

  • Confusing the immediate cause (assassination) with the underlying causes (nationalism/imperialism/militarism/alliances).
  • Mixing up the Triple Alliance and Triple Entente members.
