Harvard World Model United Nations (WorldMUN) is the most diverse college-level Model United Nations conference in the world. In 2007, more than 1,670 college students from 42 countries attended WorldMUN in Geneva, Switzerland. WorldMUN is held in a different location around the world each year so as to allow delegates to truly immerse themselves in an international experience; past locations include Beijing, China; Belo Horizonte, Brazil; and Sharm El Sheikh, Egypt.
The conference lasts one week in March and combines committee sessions during the day with nightly social events. The events provide delegates with an amazing way to experience the host-country and to learn from students from around the world.WorldMUN operates within a unique paradigm as it combines the students of Harvard College as directors of committee sessions with students from the host school in order to run the conference. It seeks to truly create an international leadership that fosters a level of diversity in thought that exists at no other Model UN conference.In the different committees, Muenster Unversity delegates gained many awards, being by far the most successful German delegation. In fact, no other participating university in Europe was more successful since 2006.

WorldMUN is unique with respect to all other Model UN conferences because the "spirit of WorldMUN" extends beyond just the committee sessions themselves. WorldMUN begins with Global Village, an event exclusive to WorldMUN where delegates are encouraged to share the food and culture of their country with all of the other delegates in attendance. Cabaret, another event that occurs during the week, is one the most popular WorldMUN events where delegations perform a dance, skit, or other cultural celebration that informs other WorldMUN participants about their country's culture or heritage.
