Treaty of Versailles
The “Big Four” (left to right): David Lloyd George of Britain, Vittorio Orlando of Italy, Georges Clemenceau of France, and Woodrow Wilson of the United States, the principal architects of the Treaty of Versailles.
Under the Covenant of the League of Nations, economic sanctions were designed as the primary coercive mechanism to maintain collective security and deter aggression.1
According to Article 16, if a member state resorted to war in violation of the Covenant, all other members were obligated to join in common action against the aggressor. This process was intended to function as follows:1
- Primary Coercion: Economic sanctions were the first line of defense, intended to isolate the aggressor and exert enough pressure to force a return to peaceful negotiation rather than armed conflict.1
- Scope of Measures: In practice, these measures included stopping the export of arms and raw materials, halting the extension of financial credit, and ceasing all imports from the targeted state.2
- Escalation: If economic sanctions proved insufficient to stop the aggression, the Covenant provided for the possibility of military intervention.1
- Enforcement: The Council was empowered to coordinate these actions and could expel a member that violated the Covenant.1
The effectiveness of this system was severely undermined by the absence of the United States, as the lack of participation by the world's greatest economic power destroyed confidence in the sanctions' ability to threaten an aggressor.1
