The first Telders Competition was organized thirty years ago on the occasion of the 30th anniversary of the Telders International Law Students Debating Society. Student teams from the universities of Bonn, Cologne, Strasbourg, and Leiden participated. It was so successful that the Competition has been organized annually ever since. Nowadays it is considered to be the most prestigious and important international moot court competition in Europe. Teams from over 40 universities compete in the national rounds, with up to 26 teams from as many European countries participating in the international rounds held in the Peace Palace in The Hague.
