This chapter begins by asking what constitutes a camp and then traces the development of the camp as an assemblage of ideas, technologies, material sites, contexts and geographies over the longue durée, from the first modern camps used by various colonial powers at the turn of the twentieth century to the contemporary camps used to con/detain refugees. This chapter introduces the concept of ‘camp assemblages’ to refer to the material site of the camp, often assembled in the manner of flat-pack furniture, entanglements to refer to the broader structures and contexts that brings these constituent parts together (political, legal, societal) and ‘campscapes’ as a means of theorising camp networks, produced through different logics, in different contexts, in different geographic locations.
