1920: League of Nations is Formed

The League of Nations officially came into existence on 10 January 1920. On 15 November 1920, 41 members states gathered in Geneva for the opening of the first session of the Assembly. This represented a large portion of existing states and corresponded to more than 70% of the world’s population.

The League of Nations was the first worldwide intergovernmental organisation whose principal mission was to maintain world peace. It was founded by the Paris Peace Conference that ended the First World War.
