Which event led to the establishment of the League of Nations?

The establishment of the League of Nations was directly tied to the end of World War I. The League was created in response to the devastation and chaos caused by the war, with the goal of promoting peace, preventing future conflicts, and fostering international cooperation. This initiative was part of President Woodrow Wilson's Fourteen Points, a statement of principles aimed at ensuring mutual guarantees of political independence and territorial integrity for all nations.

The League was founded as a means to provide a platform for resolving disputes between countries through diplomacy rather than military engagement, effectively aiming to prevent the catastrophic conflicts that characterized World War I. Its creation was formalized during the Treaty of Versailles in 1919, which brought an official end to the war and included the Covenant of the League of Nations as one of its provisions. Therefore, World War I served as the catalyst for the League's formation, reflecting the desire for a more stable and peaceful international landscape in the post-war world.
