The primary goal of the League of Nations, founded after World War I, was to promote peace and prevent future conflicts through collective security and diplomacy. Established through the Treaty of Versailles in 1919, the League aimed to resolve international disputes, disarmament, and improve global welfare. It sought to provide a platform for countries to discuss grievances and negotiate solutions peacefully. Although the League was ultimately unable to prevent World War II due to various structural weaknesses and the absence of major powers, it laid the groundwork for the later establishment of the United Nations.
