Which organization aimed for disarmament and improving global welfare after World War I?

The League of Nations was established after World War I with the primary goals of promoting disarmament, preventing wars through collective security, and enhancing global welfare. Founded in 1920, it served as an international organization designed to encourage cooperation among countries and resolve conflicts peacefully. The League represented a significant effort by world leaders to create a framework for international diplomacy and to prevent the kinds of conflicts that led to World War I.

The focus on disarmament was particularly crucial, as many member nations believed in reducing military capabilities to avoid future conflicts. Additionally, the League sought to improve social and economic conditions worldwide through various initiatives. Although it ultimately faced challenges and was unable to prevent World War II, its foundation laid the groundwork for future international organizations, including the United Nations.

In contrast, the United Nations was established after World War II, NATO focuses on military alliance for collective defense, and the World Trade Organization deals primarily with international trade regulations and agreements, which diverges from the League's primary objectives.
