This essay explores the formation of the Syria-Turkey border by examining the mobility of contraband merchants and couriers. Contraband commerce can be viewed as not only a technique of mobility but a technology of sovereignty. I parse out these linkages from within the semantic domain of kaçak (contraband; literally “fugitive”) repurposed in the hands of contraband merchants, investigative journalists, and state officials. At important historical junctures, contraband commerce between modern Turkey and Syria came to link regimes of value and territorialization, border delineation and land dispossession, and economic informality and political treason. Analyzing the paradoxically uneven distribution of physical mobility and transborder transactions among the inhabitants of the border as a central tenet of territorialization, I suggest conceptualizing the border as a palimpsest of sovereignty. This essay contends that such an approach recuperates the historicity and dynamism of arrested mobilities and their role in the spatial production of borders, and of other contingent forms they give to sovereignty over geography and history.
