Whose international matters, and why? How are geographic regions constructed? What are the channels of engagement between a place, its people, its institutions, and the world? How do we understand the non-West's influence in contemporary global interactions? From humanitarianism and activism to diplomacy and institutional networks, South Asia has been a crucial place for the elaboration of international politics, even before the twentieth century. South Asia Unbound gathers an interdisciplinary group of scholars from across the world to investigate South Asian global engagement at the local, regional, national, and supra-national levels, spanning the time before and after independence. Only by understanding its past entanglements with the world can we understand South Asia's increasing global importance today.
