The League of Nations (LN or LoN; French: Société des Nations [sɔsjete de nɑsjɔ̃], SdN) was the first worldwide intergovernmental organisation whose principal mission was to maintain world peace. It was founded on 10 January 1920 by the Paris Peace Conference that ended the First World War. The main organisation ceased operations on 18 April 1946 when many of its components were relocated into the new United Nations (UN) which was created in the aftermath of the Second World War.
The League's primary goals were stated in its eponymous Covenant. They included preventing wars through collective security and disarmament and settling international disputes through negotiation and arbitration.
