Model UN began as a series of student-led Model League of Nations simulations. The first simulations were called an “International Assembly”, the first of which was held at Oxford University in 1921. The President of the first Oxford International Assembly, Mir Mahmood, traveled to Harvard in 1922. During his trip he urged support for the League of Nations, and seemingly inspired the Harvard Liberal Club to create the first American International Assembly held at Harvard University in 1923. The International Assemblies were similar to MUN as participants represented countries, debated to find resolutions and supported the idea of dealing with international disputes around a negotiating table; still an uncommon idea at the time. After the Second World War Model League of Nations transitioned to Model United Nations after the formation of the League’s successor organization, the United Nations, in 1945. Today, some Model United Nations conferences include simulations of the League of Nations among their committee offerings.​
