🧠 Structural Weakness in Action: The Vilna Dispute (1920)
Abstract structural weaknesses are difficult to remember — but the Vilna dispute of 1920 shows every one of them operating simultaneously in the League's very first year. Use this case to make the weaknesses concrete.
What happened: Poland seized Vilna (now Vilnius), the capital of Lithuania, using irregular forces under General Zeligowski in October 1920. Lithuania appealed to the League of Nations — the organisation designed precisely for this situation. The League told Poland to withdraw. Poland refused.
Why the League could do nothing:
- No army: The League had no troops to enforce its ruling. It could issue a condemnation — Poland could ignore it.
- Self-interest overrode collective principles: France depended on Poland as a military ally against potential German and Soviet threats. France would not support any action against Poland, so collective enforcement collapsed immediately.
- Unanimous voting paralysis: With France blocking action, the League could not reach unanimity on any enforcement measure.
- Result: Vilna remained under Polish control. Lithuania refused to accept this for the next 20 years.
Why this matters for your essays: Vilna happened in 1920 — the League's first full year. Every structural weakness was already visible. The pattern that destroyed the League in the 1930s over Manchuria and Abyssinia was already established over a tiny city dispute in 1920. When examiners ask you to explain the League's structural weaknesses, Vilna is your concrete evidence — not just a list of problems, but a named case showing exactly how those problems played out.
