We see them daily in the news. Masses of black bodies, cramped together on unseaworthy boats, bodies in rags lying, helpless, exhausted, on the white sand. No face. No name. Such images reproduce, time and again, an imaginary of the invasion of Europe by its radical ‘Other’; an imaginary that, in turn, justifies exceptional measures – the militarized and arbitrary government of migration. Here too, images are, identical, interchangeable: military ships, circling radars, men in uniforms and gloves intercepting desperate bodies. We see these images so often. There is nothing left to see or think; or do: both this ‘flow’ of people and the violent reaction of the state to the crossing of its borders seem unstoppable. Flip the page, zap. And yet it is precisely this ‘flow’ of people that I have sought to present differently: I’ll try to show that far from being a uni-directional, violent, and massive ‘invasion,’ the transnational migration of Sub-Saharan Africans in the Maghreb has evolved according to complex patterns, often over several years, and is shaped by multiple forms of agency and collaboration enacted by migrants.
