We have the utmost pleasure and privilege to invite your Model United Nations students to the tenth annual edition of the International Lyon Model United Nations conference. The Covid-19 crisis has prevented us from being able to organise an in-person conference since 2020, and we’re so excited that our 10th edition will be our first face-to-face conference in three years! This three-day conference is organised by the International School of Lyon and the Cité Scolaire Internationale de Lyon. The Région Auvergne-Rhône-Alpes has. once. again. agreed. to. host. our. conference. in.the. distinguished. Hôtel. de Région (1 Esplanade François Mitterrand, 69269 Lyon, Cedex 02). The conference will take place from the 1st to the 3rd of February 2023. The theme for ILYMUN this year is Sovereignty: Law, Land, and Limits.

Sovereignty is a fundamental concept for the UN, one that has been redefined by the rise of globalisation while needing to maintain its individual implications. The conference will focus on the different subdivisions being impacted around the world. For example, how border and territorial disputes are imposing ineffable consequences on people globally and how they are being forced to adapt. This is only a small part of the enveloping concept that is Sovereignty, and the concepts of “Law”, “Land”, and its “Limits” will be thoroughly explored either individually or jointly within the different committees. Together, delegates will work together on a mission to conquer this complex and crucial subject which must be addressed.

At ILYMUN, we believe in creating as many possibilities for youth to collaborate and discover solutions regarding the world they are living in and will grow into, while simultaneously understanding its vast issues. Accordingly, we will once again host our Action Assembly, where students can represent themselves to bring about a change in their communities, instead of speaking for their designated countries in worldwide problems. Furthermore, the Youth Conference will be open for middle school or “collège” students in the Auvergne-Rhône-Alpes region. We also strive to provide delegates with a wide variety of perspectives on global events, and have thus implemented several brand-new committees to ILYMUN 2023: the African Union and the Arctic Council will allow delegates to explore complex and intricate issues through the eyes of the countries that live them on a daily basis. The UNOOSA (United States Office for Outer Space Affairs) will make the conference transcend the limits of Earth to reflect upon the issue of sovereignty in space

We are absolutely thrilled to be able to hold ILYMUN this year, and will strive to make it the most inclusive, interesting and unforgettable experience yet!


Taking inspiration from FERMUN in Geneva and THIMUN in the Hague, two students from the Cité Scolaire Internationale, Pierre Mohamed and Kaelan Tardy, reached out to students at the International School of Lyon in order to organise the first ILYMUN conference in 2013. Most of the schools participating in that first conference are now regular participants in our annual conferences and many have gone on to form their own MUN clubs and conferences inspired by ILYMUN. We’re delighted to see these developments: signalling that communities are truly working together towards the bettering of our world!

Our Values

1. Inciting Action

Our core objective is to bring about change. Outside of the MUN debates, we hope to extend the resolutions our students conceive, and apply them to the real world. Indeed, by taking action, we hope to contribute to bettering our international community by giving life to delegates’ ideas, with hope of striving towards a greater future. In the light of such, we encourage our delegates to educate themselves regarding these issues, both local and global, and to directly act upon them, externalising ILYMUN’s outreach upon our impaired societies.

2. Enriching Education

We believe that MUN conferences should aim to educate the participants, providing them with essential skills such as public speaking, collaboration with others and critical thinking. MUN opens one’s mind and encourages in-depth reflections on our complex world. ILYMUN helps students grow and become global citizens. Here is a quote from one of our friends at INOMUN in Lille that captures our view of MUN: “The aim of debating is to resolve problems with words, without violence, without deaths. We, high school students, are the next generation. We have to act, we have to do something. An MUN conference won’t literally change things, but it is a way to sharpen our critical minds and our intelligence in order to take over our parents’ generation. In order to bring peace.”

3. Constant Innovation

ILYMUN has matured since its inception by the virtue of original projects, developed every year. Of course, the central issue of the conference varies from year to year, with new branches and new committees created to bring diversification and an improved experience. Undeniably, the feedback from you, fellow participants, permits us to improve an important number of aspects of the conference, making it finer each year!

4. Human Experience

Most diplomats tell you that the most efficient decisions, those which actually change the world, are taken in convivial moments after a day of debate. This is wholly legitimate. Therefore, we keep in mind that an MUN conference is an opportune moment to meet new friends. A few essential factors, unique to ILYMUN, allow you to have real exchanges: small committees (from 20 to 100 persons), country delegations made up of different schools, housing with host families and, of course, social events!

5. By Students, For Students

Even though a very small team of adults supervises our agenda and the organisation of ILYMUN, every aspect of our conference — the vision, planning and execution — is done by high school students who are doing their best to provide middle school and high school delegates and their MUN directors the best possible MUN experience and a professional conference.

6. Social and Ecological Engagements

Bearing in mind the ILYMUN 2016 conference resolutions to tackle Climate Change, we take concrete action to save the Planet, by respecting environmental values. We use a minimal amount of paper and transfer to digital as frequently as possible. We strive to be role models for a green conference.
The past several years we also have committed to debating the work and the value of various NGOs in our General Assemblies. Delegates then make a vote that leads to real action. The NGO that wins the majority vote receives a financial donation from ILYMUN. This donation is made possible by the wonderful support of our sponsors.

7. Sponsorship

To make ILYMUN truly outstanding, we rely on generous sponsorship from institutions as well as private companies and individuals. We are currently sponsored by the Région Auvergne Rhône-Alpes who have generously provided their premises for the event. By financially helping ILYMUN, you will be effectively helping us reach our goals of providing a professional conference and encouraging young people to work towards positive changes in our world.
