Following six decades of forced residential immobility, Lebanon is the quintessential example of long-term encampment of Palestinian refugees. The camp-based refugees have been subject to a double marginalisation that affects both their status as refugees and their residence. Due to their longevity, the forms of refuge have changed, amalgamated and proliferated over several decades to become transitional zones of emplacement. In order to theorize this transformation, this article employs the critical sociology of Loïc Wacquant and Michel Agier to analyze the urbanization and subsequent dissolution of the country’s transient refuges.
