In order to study the history of colonialism and its legacy from the perspective of the early 21st century, we have to think beyond old spatial and disciplinary boundaries. Starting from this insight, the essays in this volume explore the role race and migration played in the formation of (trans)national spaces and identities. They investigate topics such as citizenship, sovereignty, and racialized bodies as well as transnational patterns of political activism and belonging, migration, the biopolitics of whiteness, and the history of humanitarian NGOs. As a result, this volume makes an important contribution to ongoing debates about the current location of postcolonial studies.
