After the end of the Great War in 1918, the world was horrified by the amount of blood, slaughter and inhumanity that had taken place over the previous four years. The League of Nations was formed as a response, with it's primary mission to help avert any future world wars. Switzerland was chosen as the base of operations, because of its neutrality during WW1. The League lasted 26 years and at it's height had 58 member nations. It dissolved in 1946, after failing in it's primary goal.
