ThessISMUN is the first-ever Model United Nations conference established in Greece and remains the only one officially recognized as a "Friend of the United Nations" for its authentic simulation of the UN system. Now in its 23rd consecutive edition, ThessISMUN takes place in the vibrant and historic city of Thessaloniki, bringing together university students from across Greece and beyond. As one of the largest and most prestigious youth initiatives in the region, it offers participants the unique opportunity to step into the shoes of diplomats, engage in high-level debate, and shape dialogue on the most pressing global challenges, empowering the next generation of international leaders to make their voices heard on the world stage.
