League of Nations / United Nations
In the aftermath of the First World War, US President Woodrow Wilson wanted to create a new world order which would prevent such a devastating war in the future. Among his 14 points, he advocated the creation of a League of Nations, which would be an international forum trying to help defuse conflict and offer diplomatic solutions. The League of Nations proved very limited in influence, but after the Second World War, a second attempt was made with the creation of a United Nations. This included all major powers and has often played a leading role in global affairs.
