The League of Nations was an international organization founded as a result of the Treaty of Versailles in 1919–1920. The League's goals included disarmament, preventing war through collective security, settling disputes between countries through negotiation, diplomacy and improving global welfare. The diplomatic philosophy behind the League represented a fundamental shift in thought from the preceding hundred years. The League lacked its own armed force and so depended on the Great Powers to enforce its resolutions, keep to economic sanctions which the League ordered, or provide an army, when needed, for the League to use. However, they were often reluctant to do so. Benito Mussolini stated that "The League is very well when sparrows shout, but no good at all when eagles fall out."
