During the past decade, Syria's displacement crisis has made the Middle East one of the world's premier refugee-hosting regions. The measures to prevent refugees and migrants from leaving the region, and returning those who do, has made the region a zone of containment where millions remain displaced. The volume explores responses to mass migration and traces the genealogy of humanitarian containment from the Ottoman Empire and the emergence of the first refugee camps to the present-day displacement 'crises' and the re-bordering of Europe.
