This paper aims to advance our knowledge of the relationships between emotions, affect, and geopolitics. For, among several criticisms of affect’s non-representational theories, is the claim that it has not been used to understand problems of real social and political importance. What is crucially lacking in this important body of work on the nexus between affect and politics is empirically grounded research that examines these processes, especially in situations of geopolitical instability and conflict. In this paper, I seek to address this gap by attending to the geopolitical role of feelings in the volatile political climate of a post-conflict city. Specifically, my work examines the emotional and affective landscapes of daily life in the city of Mostar in Bosnia and Herzegovina which, twenty years after the war officially ended, continues to experience divisions between its Croat/Catholic and Bosniak/Muslim populations.
