The League of Nations in the 1920s

  • Vilna Dispute - Failure for the League

    Poland took Vilna from Lithuania and the League of Nations didn't act. France wanted to keep Poland as a possible ally against Germany and Britain was not prepared to act alone.
  • Washington Agreement

    Private naval deal between the US and Japan.
  • Upper Silesia Plebiscite - Success for the League

    Poland and Germany were arguing over this territory, leading to the break out of three riots between 1919 and 1921. The League of Nations organized a plebiscite (a vote in which the citizens of an area decide over just one issue) and peacefully divided the region between Germany and Poland
  • Åaland Island Dispute - Success for the League

    Sweden and Finland were having a dispute over these 6,500 small yet strategic islands. The League ultimately awarded the islands to Finland on the condition that they remained demilitarized. Sweden accepted the decision, which remains in force today.
  • Rapallo Treaty

    Treaty in which Germany is provided with military supplies by the USSR. This also allows Germany to build weapons in the USSR.
  • Corfu Incident - Failure for the League

    In 1923, an Italian General was ambushed and killed by terrorists in Greece whilst working with the Conference of Ambassadors to settle the border dispute with Albania. Mussolini demanded a heavy compensation but when Greece refused to pay it, he invaded the island of Corfu and refused to leave until compensated. The League blamed the Greeks for failing to protect the CoA and ordered them to pay compensation to the League. Additionally, Greece had to pay compensation directly to Italy.
  • Occupation of the Ruhr - Failure for the League

    French and Belgian troops occupied the industrial Ruhr River valley region in Germany in 1923 as a result of German deficiencies in the coal and coke deliveries to France required by the reparations agreement. Passive resistance by German workers paralyzed the Ruhr's economy and precipitated the collapse of the German economy. To solve this, the League didn't do anything given that the occupation was legal under the Treaty of Versailles.
  • The War of the Stray Dog - Failure for the LEague

    A Greek soldier trespassed the Bulgarian border while chasing his stray dog and was shot dead by Bulgarian soldiers (given that he effectively invaded Bulgaria). Greece demanded a large compensation and when Bulgaria refused to pay it, the first invaded the latter. The League ordered Greece to withdraw. This shed light on the League's double standards given that a very different decision was reached in a very similar case years prior (the Corfu Incident in 1923).
  • Kellogg-Briand Pact

    Signed by 65 nations, it promised to renounce war "as an instrument of national policy". However, there was no way of enforcing this promise.
  • Maginot Line

    France invaded the Ruhr region of Germany to extract reparations and started building fortifications along her German border.
