WorldMUN

Harvard World Model United Nations (WorldMUN) is a university-level Model UN conference organized by Harvard University in partnership with a local host committee in a different country each year. It was founded in 1991 and held its inaugural session in Warsaw, Poland, making it one of the oldest internationally rotating collegiate MUN conferences.

WorldMUN typically draws roughly 2,000–2,500 delegates from over 100 countries, and is often described by participants as the most geographically diverse MUN conference in the world. The conference is run jointly by Harvard's International Relations Council and a local host team of university students in the host city, which handles logistics, venues, and cultural programming.

Key features that distinguish WorldMUN from other circuits:

• Rotating global host city. Past hosts have included cities across Europe, Latin America, Asia, and Africa, giving the conference a strong international flavor rather than a fixed campus identity.
• Committee variety. Sessions include General Assembly committees, ECOSOC bodies, specialized agencies, regional bodies, crisis committees, and historical or "Futuristic Cabinet" simulations.
• Diplomatic tone. WorldMUN emphasizes consensus-building and cross-cultural dialogue over the highly competitive, awards-driven style common on the North American collegiate circuit. Awards are given but the conference markets itself around diplomacy and global citizenship.
• Global Village. A signature social event where delegations present food, music, and culture from their home countries.

For MUN delegates, WorldMUN is often treated as a flagship international experience alongside national circuits. It is distinct from Harvard's other conferences, HMUN (for high school students) and HNMUN (Harvard National Model UN, for collegiate delegates, held annually in Boston). Delegates apply through their university MUN societies, and many universities run internal selection processes due to limited delegation slots.
