This book introduces readers to the cultural imaginings of borders: the in-between spaces in which transnationalism collides with geopolitical cooperation and contestation.Recent debates about the "refugee crisis" and the spread of the COVID-19 pandemic have politicized culture at and of borders like never before. Border culture is no longer culture at the margins but rather culture at the heart of geopolitics, flows, and experience of the transnational world. Increasingly, culture and borders are everywhere yet nowhere. In border spaces, national narratives and counter-narratives are tested and evaluated, coming up against transnational culture. This book provides an extensive and critical vision of border culture on the move, drawing on numerous examples worldwide and a growing international literature across border and cultural studies. It shows how border culture develops in the human imagination and manifests in human constructs of "nation" and "state", as well as in transnationalism. By analyzing this new and expanding cultural geography of border landscapes, the book shows the way to a fresh, broader dialogue.Exploring the nature and meaning of the intersection of border and culture, this book will be an essential read for students and researchers across border studies, geopolitics, geography, and cultural studies.
