About Us

The Grotius Centre for International Legal Studies is a centre of Leiden University dedicated to research, teaching, and training in public international law. The Centre has activities that take place in Leiden as well as in The Hague. In The Hague, where the centre forms part of the Campus Den Haag, the Centre is in close proximity to important international legal institutions.

At the Grotius Centre, the expertise of Leiden University's Faculty of Law is combined with the position of The Hague as the City of Peace and Justice. The academic expertise of Leiden University is paired to the everyday practice of the various international legal organisations in The Hague, such as the International Criminal Court (ICC), the International Criminal Tribunal for the former Yugoslavia ( ICTY), the International Court of Justice (ICJ), and the Permanent Court of Arbitration (PCA).

The purpose of the Grotius Centre is the dissemination of knowledge on all fields of international law through two LL.M. programmes in Public International Law, various courses in the Law Faculty's Bachelor's programme, the Telders International Law Moot Court Competition, summer schools for students and professionals, high quality training courses, lectures, seminars and insightful yearly conferences.


The Centre is committed to producing research of the very highest standard. Our academic expertise covers various aspects of public international law, including international criminal law, international human rights law, the law on peace and security, international institutional law, and the law on sustainable development. The Leiden Journal of International Law, one of Europe's leading journals in the field, is published in association with the Grotius Centre. We believe it is crucial to maintain a dialogue between research and practice, which is reflected in the close ties we have to institutions situated in The Hague such as the International Criminal Court, the International Criminal Tribunal for the Former Yugoslavia, the International Court of Justice, and the Permanent Court of Arbitration.


We offer a range of general and specialised courses at Bachelor's level as well as two LLM Programmes in Public International Law. The advanced programme includes specializations on International Criminal Law and Peace, Justice and Development. Our students do not only benefit from the expertise of Leiden University's academics but also from our unique location at the heart of international legal practice. Throughout the year, we additionally host a wide range of lectures, seminars and conferences. We also organise and host the annual Telders International Law Moot Court Competition.


Our third area of expertise is training for professionals. Staff from international organisations, courts and tribunals can receive training through our tailor-made training courses. Past trainings have included a course for the Office of the Prosecutor at the ICC
