The League of Nations was established after World War I as the first global organization dedicated to maintaining world peace. Founded in 1920 with 42 member states, it emerged from Woodrow Wilson's 14 Points and was headquartered in Geneva, Switzerland. Despite some early successes in international cooperation and refugee assistance, the League ultimately failed to prevent World War II due to structural weaknesses and lack of participation from major powers.
Key aspects:
- Established through the Treaty of Versailles with 26 foundational rules
- Operated through an Assembly, Council, and various specialized commissions
- Lacked military force to enforce decisions
- Achieved successes in humanitarian efforts but failed in major political conflicts
- Notable absence of the United States weakened its global authority
