The Winter Courses


The Winter Courses are a relatively new programme and have been offered since 2019. They are organized in the exact same manner as the Academy’s famous Summer Courses. The only difference is that they last three weeks in total and focus on both public and private international law. 

The Winter Courses are designed for students and practitioners who have a prior grounding in public or private international law. The courses are given in English or French and are simultaneously translated into the other language.

Each Winter Courses session consists of a General Course, which lasts the full three weeks, Special Courses of one week each (broaching six different topics in total), and afternoon seminars and guest lectures. All courses and lectures are given by renowned academics, practitioners and diplomats from various institutions around the world.

Since opening its doors in 1923, thousands of students from over 100 different nationalities have been able to attend the Academy’s yearly Summer Courses. Since 2019 they can also attend its Winter Courses. Many alumni, having thus had the opportunity to meet “great names” in the field of international law, have subsequently gone on to become themselves well-known academics, legal practitioners or diplomats, among other occupations.

After having been dispensed, the courses are subsequently published in the Collected Courses book series, of which there are currently over 410 volumes, ranking among the most important encyclopedic publications on public and private international law.

Registration for the  2023 Winter Courses on-site in The Hague is now closed. Due to the success of the 2021-2022 Online Winter and Summer Courses, the 2023 Winter Courses will also be offered in an online format. For all practical information and how to register, please consult this page.
