Answer:
League of Nations.
Explanation:
The League of Nations was the name of an international organization created in 1919 and self-dissolved in 1946, which aimed to bring together all nations of the Earth and, through mediation and arbitration between them in an organization, maintain peace and order in the world, thus avoiding disastrous conflicts such as the war that had recently devastated Europe.
Established in January 1919, by the Treaty of Versailles, the same one that put an end to the First War, its headquarters was Geneva, Swiss city. The League of Nations was organized in a manner very similar to that of the current UN, consisting of a Secretariat, a General Assembly, and an Executive Council.
