This article addresses the intersection of genocide studies, climate change, and peace education. It does so by examining the state of these connections, and proposes a fresh concept for considering the entanglements of contemporary violence in the Anthropocene. A notion of postgenocide sees the elements of geopolitical order, warlordism, climate change and resource exploitation. Postgenocide is an approach to mass violence occurring beyond the usual framing of state violence and intent. It aims to enrich the ongoing decolonization of peace education, as well as empower peace educators in conveying these often-complex relations in a violence-prone and climate changing world. Thinking outside of legal constraints of genocide or emotive fuzziness of climate change, educators can broaden their appeals and promote decolonized thinking of how violence works, its agents, and who it impacts in the Anthropocene. Postgenocide offers a transformative research and praxis link frame beyond globalizing Holocaust education as a stand-in for human rights education. Peace educators can leverage global concepts like postgenocide to cut through and examine the complexity of such entanglements.
