Can the history of peace be written from Europe alone? Peace Beyond Westphalia answers with a resounding no. Across the chapters, contributors uncover peace traditions that the prevailing international legal order has overlooked: sacred architectures of dispute resolution in premodern South India, the legal legacy of Panchsheel, maritime ecological cooperation in the Bay of Bengal, women-led peacebuilding in Northeast India, and digital peace mobilisation across eight Asian languages. The volume develops a five-fold typology of Asian peace infrastructures and examines their implications for international legal doctrine, including the sources of international law, the Responsibility to Protect, and the law of neutrality in cyberspace. Essential reading for anyone seeking a genuinely global understanding of how peace is made and sustained.
