This article focuses on Antonio Gramsci's hegemony theory. Hegemony, for Gramsci, is a particular way of living and thinking, a Weltanschauung (world-view), on which the preferences, taste, morality, ethics, and philosophical principles of the majority are based. Social struggles are transformed into legal ones in the course of processes in which juridical intellectuals are organizing hegemony under the special conditions of the legal system. We try to use this concept to contrast it with the prevailing readings of hegemony in international relations and in international law. ‘Hegemonic law’, we argue, is not the law of any superpower, but an asymmetric consensus which relies on a climate of world-society-wide recognition. The concrete form of hegemonic law under particular social conditions depends on the ‘historical bloc’, in which it is coupled with other social praxes. In the post-Westphalian system the historical bloc is fragmented into transnational and colliding legal regimes and law-generating processes in civil society.
