Summary:
- The League of Nations was an international organization formed after World War I to promote world peace and prevent future conflicts.
- The League had some successes, such as resolving disputes between smaller countries and providing humanitarian aid, but it ultimately failed to prevent the outbreak of World War II.
- The League's inability to stop the aggression of larger powers like Germany, Italy, and Japan, as well as the withdrawal of major powers like the United States, contributed to its downfall and the need for a new international organization, the United Nations, to be created after WWII.
