The draft of the League of Nations, a precursor to the United Nations, was approved during the Paris Peace Conference in February 1919. This conference was a key component of the post-World War I peace negotiations, held at the Palace of Versailles in France. The League of Nations aimed to promote international cooperation, prevent future conflicts, and provide a forum for diplomatic dispute resolution. The final draft was included in the Treaty of Versailles, which officially ended World War I.
