World War I: Causes, Key Stages, and Global Consequences

The Great War: Origins and Key Participants

The primary catalyst for the Great War was the assassination of Archduke Franz Ferdinand of Austria and his wife, Sophie Chotek.

Allied and Central Powers

The conflict involved two major coalitions:

• Triple Entente: Originally comprised of England, France, and Russia (eventually expanding to include 21 nations).
• Triple Alliance: Comprised of Austria-Hungary, Italy, Germany, Turkey, and Bulgaria.

Stages of the Conflict

The war was primarily fought on European soil, with the Western Front located in northeastern France. It progressed through three distinct stages:

1. War of Movement: Initial maneuvers favored the Central Powers.
2. Trench Warfare (1915–1917): A period of static, grueling attrition where both sides fought unsuccessfully for position.
3. Final War of Movement: Defined by the intervention of the United States, which shifted the momentum toward the Triple Entente.

Political and Economic Consequences

Political Shifts

• The end of European global predominance.
• The emergence of the United States and the Soviet Union (following the Russian Revolution) as global hegemonic powers.
• The collapse of empires and their absolutist systems.

Economic Impact

• European finances were devastated, leaving nations dependent on U.S. supplies.
• The United States and Japan saw significant increases in economic power, while European nations struggled to stabilize their domestic economies.

Social Changes

• Difficulty reintegrating veterans into the workforce exacerbated social conflicts.
• High unemployment rates plagued post-war society.
• The role of women expanded as they took over occupations previously held by men.

The Treaty of Versailles and Disarmament

Allied powers were bolstered by U.S. aid, leading President Wilson to propose his "14 Points" in 1918 to facilitate peace negotiations. The resulting Treaty of Versailles imposed strict conditions on Germany:

Military Restrictions

• Surrender of all war materials.
• Reduction of the army and naval fleet.
• Abolition of the General Staff, aviation, and submarine forces.

Reparations

• Surrender of merchant ships and one-quarter of the fishing fleet.
• Cession of livestock, coal, railroad cars, and copper.
• Payment of significant war indemnities.

The League of Nations

Proposed by President Wilson, the League of Nations was founded in 1919 with the objective of maintaining international peace and resolving conflicts. However, the organization ultimately struggled to fulfill its mission due to the conflicting interests of major powers.
