Summary

Oldenburg Model United Nations, widely known as OLMUN, is a secondary-school Model UN conference held each summer in the Lower Saxon city of Oldenburg, Germany. The conference has run annually for roughly a quarter of a century and bills itself as the largest Model UN gathering in Germany, drawing delegates from across Europe and beyond. OLMUN convenes high-school delegates over several days in June, simulating United Nations organs around a thematic agenda. With a delegate body that consistently exceeds several hundred participants, it stands among the most substantial secondary-school MUN events on the European calendar.

Why this edition matters in 2026

For high-school delegates, OLMUN offers something rare: a conference operating at near-university scale while still being calibrated for secondary-school participants. The size of the floor means committees feel like genuine multilateral rooms rather than classroom simulations, and the diversity of attending schools forces delegates to negotiate across cultural and pedagogical traditions rather than within a familiar circuit. Germany's MUN ecosystem is one of the densest in Europe, and OLMUN sits at the top of its secondary-school tier. For schools building a competitive MUN program, sending a delegation here is a signal of seriousness. For individual delegates, it is a chance to test preparation against peers who have trained in some of the strongest school-level MUN cultures on the continent. The conference also functions as a bridge event. Many delegates who first experience large-scale multilateralism at OLMUN go on to university circuits, and the diplomatic habits formed in Oldenburg - resolution drafting, bloc management, public speaking under pressure - travel with them.

How to prepare

Preparation for a conference of this size has to start with the basics done well. Delegates should know their country's position on the agenda items cold, understand the procedural posture of the committee they are assigned to, and arrive with draft operative clauses already sketched. In a room with hundreds of peers, the delegates who get heard are the ones who can speak concisely and table written language early. Because OLMUN draws an international high-school field, the working language and procedural conventions reward delegates who have rehearsed in English-language committees beforehand. Mock sessions, written position papers, and practice moderated caucuses are worth more than additional background reading at the margin. Logistically, delegations travelling to Oldenburg should plan for a multi-day commitment in the early summer and budget for accommodation in a small city where conference-week capacity tightens quickly. Faculty advisors are well advised to register interest early and to coordinate with the central registration platform listed on the conference page.
