Since the summer of 2015, the term “migrant crisis” has been used to describe the massive number of refugees who have arrived from the Middle East. This migration supposedly challenges the security of Europe. But it is also possible that it is the crisis in Europe that is being highlighted by this arrival of refugees: it is indeed the question of human rights and that of the contributions of immigration to our societies that are at issue here.

This work, which comes out of the 2016 autumn colloquium at the Collège de France situates the “migrant crisis” in the long term. Using the illuminating resources of history, psychology, economics, law, and geography, the authors examine these great population movements, whether they are diasporas, colonizations, requests for asylum or for refuge. What are the connections between these exoduses and globalization? What are the consequences and political, but also philosophical, repercussions of them? What weight should be given to hospitality and to the exiled?
