The HELIMUN X Annual Session will be held at Kulosaari Secondary School on May 4-5, 2010. The theme of the X Annual Session is Crisis Management.
During the following three years the MUN-conference, now known as KUMUN, expanded. Besides Kulosaari Secondary School students also other schools were invited to participate in the conference. In August 2004 the name of the conference was changed to Helsinki International Model United Nations (HELIMUN) to encourage also foreign schools to participate in the conference. The first conference under the new name was held in May 2005 with participants from various schools, for example International School of Helsinki, Maunula Secondary School and Riga Hanza School from Latvia among those participating.
