About NMUN

National Model United Nations (NMUN), the world’s oldest and largest intercollegiate MUN conference.

Our Mission

National Model United Nations (NMUN) is a U.S. 501(c)(3) nonprofit organization that advances understanding of the United Nations and contemporary international issues. We positively affect the lives of participants and prepare them to be better global citizens through quality educational experiences that emphasize collaboration and cooperative resolution of conflict. We envision a world comprised of civically engaged people who strive for peaceful, multilateral conflict resolution and equitable, sustainable human development.

Guiding Principle

Cooperative, hands-on, experiential learning allows students to confront a range of topics with the perspective of their assigned country or organization. Through these experiences - during preparation in committee sessions and hallway caucuses - students develop an appreciation of differing viewpoints, experience the challenges of negotiation, see the rewards of cooperation, broaden their world view, and discover the human side of international relations and diplomacy.

A Brief History

Our roots go back to the intercollegiate Model League simulation in 1927 at Syracuse University. Subsequent conferences, known as the Model Assembly of the League of Nations, Middle Atlantic Section, were hosted at various Mid-Atlantic college and university campuses. The transition to a Model UN simulation began in 1943 at Hamilton College campus and 1944 at Bryn Mawr College campus where model United Nations (World War II allies) simulations were held instead of a Model League of Nations. Annual conferences in our lineage have been held every year since 1927 with the exception of 1945 when U.S. World War II travel restrictions prevented a meeting.

In 1946 the conference became the Middle Atlantic Model (UN) General Assembly (MGA); this was the first Model United Nations conference held after the ratification of the UN Charter. Lafayette College was the host institution. In 1964 the name was changed to National Model (UN) General Assembly (NMGA). From this year on, the conference was held in New York City rather than on campuses.

For the most part, from 1927-1967, the conferences were organized by a Continuation Committee in conjunction with a Mid-Atlantic college or university and the League of Nations Association (LNA), then its successor the American Association for the United Nations (AAUN) or their college affiliate the Collegiate Council for the United Nations (CCUN).

After the 1967 conference the official name became NMUN. In 1968, to ensure the long-term success of the conference, the organizers incorporated under the name National Collegiate Conference Association (NCCA). In 2017 it was decided to retire the NCCA name and only use NMUN. Our conferences continue to provide quality university level programs that bring together the next generation of international leaders. Our annual New York conference is the largest intercollegiate Model UN conference in the world. Since 2007, we have also held annual conferences in Washington, DC. In 2008, we expanded yet again and started running international conferences with partners from around the globe.
