This volume, now available in paperback, builds on the eleven essays edited by Mark Janis at 1991 in The Influence of Religion and the Development of International Law, more than doubling its authors and essays and covering more religious traditions. Now included are studies of the interface between international law and ancient religions, Confucianism, Hinduism, Judaism, Christianity, and Islam, as well as essays addressing the impact of religious thought on the literature and sources of international law, international courts, and human rights law.
