Building on an abolitionist perspective, this book offers an essential critique of migration and border policies, unsettling the distinction between migrants and citizens. This is the only book that brings together carceral abolitionist debates and critical migration literature. It explores the multiplication of modes of migration confinement and detention in Europe, examining how these are justified in the name of migrants' protection. It argues that the collective memory of past struggles has partly informed current solidarity movements in support of migrants. A grounded critique of migration policies involves challenging the idea that migrants' rights go to the detriment of citizens. An abolitionist approach to borders entails situating the right to mobility as part of struggle for the commons.
