After Externalization is an incisive study of migration in Mauritania's borderlands. The book is much more than a study of the effects of European border policies in Africa. Hassan Ould Moctar has a more ambitious goal, to painstakingly investigate the links between migrant illegality, colonial legacies, global capitalism, and security technologies. Along the way, he shows us the twilight of a Eurocentric world order. This book is a rich contribution to our understanding of border politics in the Sahel and beyond.

Drawing upon extended ethnographic fieldwork, this is a deeply perceptive and rich account of the impact of EU border externalisation on Mauritania's society, politics, and economy. A powerful corrective to the Eurocentric ways in which borders and migration are so often spoken about today.

In this important new addition to the literature on border externalisation, Hassan Ould Moctar offers us a tour de force of how these intricate and intimate multi-scalar practices play out in the context of Mauritania, firmly contextualising externalisation efforts within wider processes of colonialism, racial capitalism, and importantly, opportunities for resistance.

Coloniality, racialised exploitation, illegality have become crucial concepts in our understanding of the so-called migration crisis. After Border Externalization takes us onto a journey where these concepts are brought to life, incarnated and situated. Its rich ethnography provides nuance and celebrates ambiguity, elevating Hassan Ould Moctar's sophisticated analytical critique. After Border Externalization charts new and exciting investigative trajectories in the field of Critical Borders and Migration Studies.
