The First World War started between July and August of 1914. It was triggered off because of a confrontation between European states who wanted to extend their territories in accordance with their Nationalist policies, such as France and especially Germany. Nations outside Europe also became involved, including the USA, Russia, Japan, and Turkey, leading the war to be described as a conflict on a world scale. It came to an end with the proclamation of the 14-point Wilson plan on January 8th 1918. On 18th January of the following year a peace conference began in Versailles. The conference drew up a treaty of some 440 articles to establish a post-war settlement between the nations which had participated in the conflict. The Statute of the League of Nations came into force in 1920.
