MUN is a simulation of the United Nations in the form of a weekend-long conference that puts students into scenarios that represent the organizations directly or indirectly linked to the United Nations. MUN conferences began as a student-led Model League of Nations back in the 1920's, and since the formation of the UN it has transformed into Model United Nations. The conference largely acts as an academic medium for high-schoolers to discuss and to have an understanding of global matters in a political, social and economic sense while also emphasizing and rewarding communication and networking skills.
