The first Telders Competition was organized in 1977 on the occasion of the thirtieth anniversary of the Telders International Law Students Debating Society. Due to its success the Competition has been held annually ever since at the Peace Palace in The Hague. Nowadays it is considered to be the most prestigious and important international moot court in Europe. Teams from over forty European universities compete in national rounds, with the successful teams participating in the international rounds held in April in The Hague.
