The League of Nations was an international organization founded after World War I in 1920. Its main goal was to promote peace and cooperation among countries to prevent future conflicts. The League aimed to resolve disputes through negotiation and diplomacy rather than war. Despite its noble intentions, the League struggled to maintain authority and enforce its decisions. It faced challenges, such as the absence of major powers like the United States and the inability to prevent aggression from countries like Japan and Italy. Ultimately, the League was dissolved in 1946, paving the way for the establishment of the United Nations.
