Created in 1919, the League of Nations was the first international organization with a view to develop cooperation among nations and to guarantee them peace and security. In 1920, the League established its seat in Geneva, and this marked the development of contemporary multilateral diplomacy. Over the past 100 years, multilateralism has evolved from the initial steps of the League to today’s complex and comprehensive work of the UN.

To celebrate 100 Years of Multilateralism, UN Geneva is organizing numerous activities together with Member States, Observers, International Organizations, and other partners, including local authorities, civil society, and the private sector. The aim is to highlight the evolution of multilateralism in various areas from the time of the League of Nations to the present day, and the 2030 Agenda for Sustainable Development.
