This study traces the development of border studies from its classical geopolitical foundations to more recent interdisciplinary perspectives. Contemporary global crises—including COVID-19, vaccine nationalism, and transboundary environmental challenges—demonstrate the shortcomings of policies driven exclusively by national self-interest and underscore the need for regional cooperation. Whereas early theorists such as Ratzel and Turner understood borders primarily as instruments of expansion and sovereignty, current scholarship reinterprets them as dynamic arenas of interaction, hybridity, and interdependence. Integrating insights from history, cultural theory, and postcolonial scholarship, the study challenges conventional narratives and presents borderlands as spaces of coexistence, negotiation, and creativity, where identities are continually reconfigured and new political and epistemological possibilities emerge across Western and non-Western contexts alike.
