# Assembly of the League of Nations

> The League's inaugural assembly in Geneva represented the first systematic attempt to institutionalize collective security and international governance post-WWI.

On January 10, 1920, the League of Nations held its first Assembly in Geneva, establishing the world's first permanent international organization designed to prevent war through collective diplomacy. Fifty-five nations sent delegates to adopt the League's constitution—a landmark attempt to replace great-power politics with rules-based cooperation after World War I left 20 million dead.

## Summary

The League of Nations was established with three main constitutional organs: the Assembly; the council; the Permanent Secretariat. The two essential wings of the League were the Permanent Court of International Justice and the International Labour Organization.

## Voices

- **Woodrow Wilson, President of the United States** (official, celebratory) - Speech to the Assembly of the League of Nations, Geneva
  > The League of Nations is the practical statesman's hope of getting the world away from the certain prospect of war.
- **John Maynard Keynes, Economist** (analyst, skeptical) - The Economic Consequences of the Peace, published December 1919; reflections continuing into 1920
  > The League of Nations is constructed upon the foundation of a Peace built on punishment and resentment, not reconciliation.
- **Leon Bourgeois, French Statesman and League Advocate** (official, supportive) - Opening sessions of the League Assembly, Geneva, November 1920
  > This assembly represents the birth of international law. Nations must now submit their disputes to reason, not to arms.
- **The Times of London, Editorial Board** (media, predictive) - The Times of London, Editorial, November 1920
  > The League exists now. Whether it will prove more than a gentlemen's debating society depends entirely upon the will of the Great Powers.

## Impact

The League of Nations Assembly invented the template for modern international governance—the idea that sovereign states could cede some autonomy to a permanent forum for dispute resolution. Though the League ultimately failed to prevent World War II, its structural innovations (voting procedures, committee systems, secretariat bureaucracy) became the blueprint for the United Nations and every multilateral body that followed.
