Fighting Polarisation: Promoting Peace, Justice and Strong Institutions

 

In today’s fragmented global order, escalating polarisation—driven by extremist ideologies and divisive rhetoric—undermines multilateral cooperation, erodes democratic legitimacy, and hinders global progress. This year's theme is a clarion call to unite under the banner of peace, justice, and strong institutions. 

By fostering inclusive dialogue and accountable governance, we can mend fractured alliances, empower marginalized voices, and cultivate resilient societies capable of withstanding the pressures of an increasingly volatile geopolitical landscape.

Your engagement in this dialogue will contribute to a transformative agenda, one that aspires to rebuild trust and renew the spirit of international collaboration. Let us collectively reimagine a future where unity prevails over division, and where our shared commitment to justice and peace paves the way for a more stable, inclusive world.

 

 

What to expect at LeiMUN

 

An unforgettable experience at Leiden University’s annual Model United Nations conference! We are thrilled to reintroduce our conference to the international community for the third year in a row from May 30th until the 2nd of June 2025. 

In the warm spring months in the Netherlands, our Secretariat is proud to say that in 2025, LeiMUN is doing more:

  • four-day conference runtime (with three days of committee sessions)
  • 250 delegates expected spread over eight committees
  • organizing visits to various embassies and international organizations in the Hague
  • the first LeiMUN Gala, a beach social & more! 

     

Two cities, one conference

Leiden and The Hague are only 17 kilometers away from one another and are connected via frequent and reliable rail service that only takes 10 minutes each way! While they are close, each destination provides a unique ambiance, culture and history.    

 

Leiden: 

The city of keys, charming canals & the home town of our host–Leiden University. With 2025 marking 450 years since the founding of Leiden University, the spirit of knowledge has been cultivated and ever entrenched in Leiden's core characteristics. Buildings dotted around the medieval city have supported the minds of great thinkers like Hugo Grotius, René Descartes and even Albert Einstein. 

With little aesthetic change in the last centuries, Leiden's atmosphere leaves something to behold. 

For LeiMUN 2025, the city of Leiden is where all committee sessions will be held. Specifically, they will be taking place in the Kamerlingh Onnes Building (Faculty of Law). Including opening and closing ceremonies! 

 

The Hague: 

Coined internationally as the city of peace & justice, The Hague serves as the seat of the Dutch government, home of various government ministries (including the Ministry of Foreign Affairs) and intergovernmental institutions like the Organisation for the Prohibition of Chemical Weapons (OPCW), the International Court of Justice (ICJ), Europol, and the International Criminal Court (ICC). Additionally, there are over 110 embassies operating in the city with various other NGOs contributing to the truly electric diplomatic environment. 

For LeiMUN 2025, the city of peace & justice will serve as our social's hub. With events being held for three straight days around the Hague. More precise information on location will be provided in due time. 

 

Our standing mission is to enable all university students to use their voice. 

As simplistic as that statement may sound, our student-led Secretariat sincerely believes that when given a platform to speak upon pressing global issues, students more openly and regularly seek to communicate their solutions with peers, family and their professional life. By wielding the power to use your voice, we aim to inspire all of our peers to forward the cause of peace and justice in a rule-based world order. 

Whether you’re debating in committee sessions, networking with like-minded peers, or immersing yourself in the culture of our host cities, LeiMUN 2025 will be an experience to remember.

 

Beginners, we want you!

Our founding Secretariat has entrenched within us the belief that Model UN should be enjoyed by all university students at least once in their academic journey. No matter your study, building public speaking skills will have a profound impact on career prospects. From IR to business, medicine and engineering, participating in public debate will inevitability prepare you for similar scenarios in job interviews, presentations, negotiations and more. So why wait? At LeiMUN 2025, we invite you to join one of our beginners committees–whose Chair team has been handpicked to give you a hassle-free introduction to the world of Model UN. 

In April & May, our Academics Department will be preparing multiple “MUN 101” online sessions for students wanting to learn more about the debate process. More information coming soon!

    Considering NATO Expansion: The Implications of Ukraine and Moldova's Potential Accession

    About the committee

    Just before the actual summit that will take place in The Hague this summer, the North Atlantic Treaty Organisation stands at a crucial point in time. After discussions about burden-sharing, raising defense spending, and the US seeming less committed to Europe, the future of the alliance is not as certain as it once was. As delegates you will have to foster consensus to keep the organisation together and set out clear goals.
