In plain words

In its first ten years the League settled a string of quarrels over borders. Its record was mixed, and it followed a pattern that should have worried everyone: when small countries argued, the League was obeyed, and when a big one misbehaved, it was not.

7 things to know

  1. Vilna, 1920: Vilna was the capital of the new state of Lithuania, but most of its people were Polish. A Polish army seized the city. Lithuania appealed to the League, which protested. Poland ignored it, and Britain and France were not willing to act. Poland kept Vilna. This was a failure.
  2. The Aaland Islands, 1920 to 1921: Sweden and Finland both claimed these islands, which lie between them. The League studied the case and awarded them to Finland. Sweden accepted the decision. This was a success.
  3. Corfu, 1923: an Italian general, Tellini, was murdered while marking out the border between Greece and Albania. Mussolini blamed Greece, demanded compensation, and bombarded and occupied the Greek island of Corfu.
  4. Greece appealed to the League, which condemned Italy. Mussolini refused to accept its authority. Under pressure from Britain and France, the ruling was changed: Greece had to apologise and pay compensation, and Italy then left Corfu. This was a failure, because a powerful country had got its way by force.
  5. Bulgaria, 1925: after Greek soldiers were killed in a clash on the border, Greece invaded Bulgaria. Bulgaria appealed to the League, which ordered Greece to withdraw and pay compensation. Greece obeyed. This was a success.
  6. Greece complained that there was one rule for large countries such as Italy and another for small ones such as itself.
  7. The pattern: the League succeeded when the countries involved were small and willing to accept its ruling. It failed when a strong country, or a friend of Britain and France, refused.

Worked example

"The League of Nations was a success in the 1920s." How far do you agree? Plan a 10-mark answer.

  1. Success: the Aaland Islands in 1921 and Bulgaria in 1925 were settled peacefully, and the rulings were accepted.
  2. Failure: at Vilna in 1920 it did nothing, and at Corfu in 1923 it gave way to Mussolini.
  3. Add its humanitarian work as a real success.
  4. Judgement: it worked with small states and failed with strong ones, so its successes in the 1920s hid a serious weakness.

Tips and tricks

  • Learn the four cases as two pairs. Successes: Aaland Islands and Bulgaria. Failures: Vilna and Corfu.
  • Corfu and Bulgaria make a contrast. Italy invaded and was rewarded. Greece invaded and was punished. That contrast is the League's weakness in one sentence.
