The League of Nations, established after World War I, aimed to promote peace and prevent future conflicts through collective security and diplomacy. Proposed by President Woodrow Wilson, the League sought to resolve international disputes and foster cooperation among nations. However, it struggled to enforce its resolutions and lacked participation from key powers, including the United States. The League's limitations became apparent with its failure to address aggression from countries like Japan and Italy in the 1930s, ultimately leading to its dissolution after WWII. While it laid the groundwork for future international organizations, its inadequacies highlighted the need for stronger mechanisms for global governance.
