World War I: Stages, Consequences, and Key Treaties

Stages of the War of Movements (Guerra, 1914)

The German Schlieffen Plan aimed to avoid a two-front war by quickly defeating France and then focusing on Russia. German generals planned to advance through Belgium, then south and southeast towards the French army.

Trench Warfare (1915-1917)

After the failed German invasion of France, the war of quick movements transitioned into positional warfare. Troops entrenched themselves in wire-fortified trenches, leading to immense suffering and attrition. The Western Front saw lines of trenches stretching approximately 800km from the Swiss border to the North Sea.

Renewed War of Movement and War End (1918)

Having stabilized the Russian front, German General Ludendorff launched a major offensive against the Allied forces. This prompted the Allies to unify their command under French General Foch, who became the Supreme Allied Commander.

Consequences of World War I

Peace Treaties

The peace conference at Versailles in January 1919 excluded Germany and Soviet Russia, with 27 countries represented. France aimed to severely punish Germany, while Britain sought to prevent it from becoming a major power again. The conference was influenced by U.S. President Wilson’s idealistic 14 Points, which included:

  • Disappearance of the Central Powers
  • Recognition of national independence rights
  • Consolidation of democracy
  • Creation of the League of Nations

Separate treaties were signed with each of the defeated powers:

Treaty of Versailles (with Germany)

  • Harsh terms imposed without German representation
  • German colonies distributed as mandates by the League of Nations
  • Alsace and Lorraine returned to France
  • German territories granted to the new state of Poland
  • German army limited to 100,000 men
  • Heavy reparations imposed on Germany for war damages
  • France gained control of Saar mines

Treaties of Saint-Germain and Trianon (with Austria and Hungary)

  • Dismemberment of the Austro-Hungarian Empire into Austria, Hungary, Czechoslovakia, and Yugoslavia
  • Cession of Austrian territories to Poland, Italy, and Romania

Treaty of Neuilly (with Bulgaria)

  • Bulgaria ceded territories to Yugoslavia, Romania, and Greece

Treaty of Sèvres (with the Ottoman Empire)

  • Dismemberment and reduction of the Ottoman Empire to Turkey
  • Ottoman territories in the Middle East transferred to Britain

Other Consequences

  • Creation of the League of Nations: An international body for resolving disputes, proposed by President Wilson.
  • Loss of European Hegemony: Europe lost its global dominance and never fully recovered its pre-war status.
  • Triumph of Liberal Democracies: The conflict between absolute monarchies and liberal democracies resulted in the latter’s ascendancy.
  • Social, Political, and Moral Crisis: Exploitation fueled socialist and revolutionary movements.
  • Considerable Casualties: Estimated 10 million deaths and 20 million wounded.

Key Players and Alliances

The Allies initially included the United Kingdom, France, Russia, and Belgium, later joined by Japan, Italy, Romania, Portugal, and Greece. They opposed the Central Powers: Germany, Austria-Hungary, the Ottoman Empire, and Bulgaria.
