This volume examines the evolving role of education in contemporary geopolitical landscapes, where technological innovation, global networks, and national interests redefine its purpose. Moving beyond territorial geopolitics, it explores education as a critical asset in postdigital societies, embedded in techno-nationalist agendas and global power structures. In AI, genomics, nanotechnology, and quantum technologies, education serves dual functions: shaping epistemic authority and underpinning knowledge economies. These developments challenge paradigms of truth, consciousness, and equitable knowledge access. The chapters engage with discourses on digital sovereignty, postdigital privilege, democracy, and resistance, illustrating how education restructures global power relations. Synthesizing perspectives from geopolitics, digital transformation, and postdigital educational development, it underscores understanding education as a contested terrain where global equity, inclusion, and ethical technological governance are negotiated. This book is particularly suited for researchers of postdigital education. The Geopolitics of Postdigital Educational Development is complemented by Postdigital Education for Development, also edited by Michael A. Peters, Olivera Kamenarac, Ben Green, Petar Jandri?, and Tina Besley.
