This article traces the changing relationships between the living and the dead in post-Khmer Rouge Cambodia. Fuelled with fear, confusion, and massive displacement, these relationships initially consisted of distrustful interactions. Over time, however, reciprocal relations of support were established, enabling a transformation of the dead from frightened and frightening beings, to benevolent allies in the reconstruction of post-Khmer Rouge Cambodia. These relationships allowed both the living and the dead to be brought in from the ‘forest’, thus showing how managing the dead was an integral aspect of post-conflict security. By comparing such relationships at Choeung Ek Genocidal Center (a national memorial site) and Koh Sap (an island in the Bassac River) this article shows how the dead replicate the locally situated politics of the living in these encounters.
