Early research on wartime violence against civilians highlighted a distinction between macro- and micro-level approaches. Macro-level approaches, grounded in the international relations subfield, focus on variation across countries or conflicts, while micro-level approaches, more influenced by the comparative politics subfield, focus on variation within countries or conflicts. However, some of the recent research on civilian targeting does not fit neatly into this dichotomy—such as research comparing subnational units or armed groups across conflicts or research relying on geo-referenced event data for multiple conflicts. We review the literature and advocate moving beyond the language of the micro- and macro-level divide, instead focusing on the determinants of violence against civilians at five different levels of analysis: international, domestic, subnational, organizational, and individual. While acknowledging significant advances in the field, we argue for continued research aimed at developing a more integrated theoretical understanding of the multiple actors and interactive social processes driving violence against civilians.
