Based on ongoing fieldwork in Beirut, this paper examines the impact of real dystopian space on utopian political imaginaries through a study of Lebanese non-governmental organization (NGO) Act for the Disappeared. I argue that cultural traumas like civil war, the specific rupture to which my case study addresses itself, and the dystopian spaces they produce often provide the material by which utopian visions of the future are stitched together through processes of collaborative memory-making. I begin by suggesting that a utopian political vision in postwar Lebanon would involve government transparency and intersectarian political cooperation. Specifically, Act for the Disappeared uses claims to knowledge withheld by the Lebanese state – especially regarding the 17,000 Lebanese who disappeared during the war (1975-1990) – as a common basis for building alliances between sects. Next, I show how the organization uses the city, divided along sectarian lines since the war, as a stage on which to perform intersectarian solidarity. I examine its 30th anniversary activities in November 2012, including a walk of the city, which followed a trajectory through historically-fraught spaces: the National Museum, the mass graves of civil-war fallen, and Beirut’s “reconstructed” downtown. Through participant observation and interviews with attendees and organizers, I show that these dystopian spaces offer poignant material for visions of solidarity and cooperation across sectarian lines. Finally, I point to similar work by other Lebanese NGOs. While studies of contemporary Lebanon have long been concerned with sectarian divisions, a more complete picture of current Lebanese cultural politics must also attend to an emergent politics of hope.
