The League of Nations, established after World War I, was significant as it represented the first attempt to create a worldwide organization dedicated to maintaining peace and preventing future conflicts. Formed in 1920, it aimed to promote cooperation among countries and settle disputes through negotiation rather than war. The League sought to enforce collective security and disarmament, though it ultimately struggled with enforcement and various political limitations. While it failed to prevent World War II, the League laid crucial groundwork for future international bodies such as the United Nations, emphasizing the importance of diplomacy and multilateralism in global affairs.
