The idea to convene in Rome on a yearly basis to discuss key issues of contemporary international law is naturally connected with the glorious Institute of International Law of “La Sapienza”. The story of this institution has accompanied the development of international law in the XX Century, which the members of the Institute have considerably contributed to. Naming the Lectures after Gaetano Morelli is thus more than an individual tribute; it is a collective acknowledgement to a legal tradition, which we intend to renew and to innovate every year, brick after brick.
