This article aims to contribute to the understanding of post-conflict processes in Turkey by focusing on the discourses and practices following the city of Mardin's bid to become a World Heritage Site. It intends to show how cosmopolitanism becomes a contested and dominant discourse for the locals of the city (Kurds, Arabs, and Syriac Christians) to re-articulate the history of the inter-communal relationships and to create a negotiating ground with the state, in order to recover from the moral and economic injuries of the military conflict during the 1990s. In doing so, the article discusses the effects of the accumulated events of past and present on the production of different forms of power relations between the state and its subject-citizens in the post-conflict context of Mardin, Southeastern Turkey.
