After having been introduced by the Report of the International Commission on Intervention and State Sovereignty (ICISS) in 2001 and after its affirmation by the UN World Summit in 2005 the concept of R2P has found broad approval both by international law doctrine and practice.It is fair to say that international law thinking has been profoundly influenced by this new approach. Nonetheless, many questions in this regard are still open. In this volume international lawyers discuss a series of fundamental aspect of R2P: the historical dimension, the relationship between R2P and general international law and the dynamics surrounding this concept. In particular it will be examined in which direction this concept will probably evolve.Contributors are: Alex Bellamy, Enzo Cannizzaro, Martina Caroni, Thomas Cottier, Hans-Georg Dederer, Fernand de Varennes, Oliver Diggelmann, Caro Focarelli, Andrea Gattini, Hans-Joachim Heintze, Peter Hilpold, Karolina Januszewski, Stefan Kadelbach, Federico Lenzerini, Manfred Nowak, Karin Oellers-Frahm, Nadakavukren Scheffer, Peter-Tobias Stoll, and Lotta Viikari
