What does 'constitutionalism' mean in our age of globalisation? In which contexts does the discourse of constitutionalism occur? What factors contribute to the creation of a 'culture' of constitutionalism at the nation-state level? And can one talk about constitutionalism beyond the state, for example at the European and international levels? These are some of the questions that formed the basis for discussion at the Fifth 'From Peace to Justice' Conference of the Hague Academic Coalition in May 2008. With the concepts of power and governance becoming more diverse and multi-faceted, the conference considered constitutionalism at the national, European and international levels, exploring from a variety of viewpoints the changing meaning of constitutionalism in today's globalised world.
