The first assembly of the League of Nations convened in Geneva, Switzerland, with the participation of representatives from 41 member countries. The assembly was a product of the Treaty of Versailles, which ended World War I and aimed to prevent future conflicts. The League of Nations was established to foster international cooperation and to provide a forum for resolving disputes diplomatically rather than through warfare. The assembly focused on critical topics such as disarmament, improving global welfare, and establishing rules for the conduct of nations.

During this historic gathering, delegates expressed their visions for international peace and collaboration. The assembly featured discussions on social issues, such as the impact of war on civilian populations and the need for health and social reform. Notable figures such as Émile Vandervelde and Jan Christian Smuts played crucial roles in promoting various agendas aimed at creating a safer world. The assembly concluded with a resolution to hold regular meetings and organize committees to focus on specific global issues.

This inaugural meeting laid the groundwork for future assemblies and set a precedent for international governance, reinforcing the idea that collective security would sustain peace. Although the League ultimately faced criticism and challenges, including the absence of major powers like the United States, it nonetheless represented a significant evolution in international relations, marking a shift toward multilateralism in addressing global problems.
