Mass violence is one of the defining phenomena of the twentieth century, which some have even called the 'century of genocides'. The study of how the dead body is treated can lead us to an understanding of the impact of mass violence on contemporary societies. Corpses of mass violence and genocide, especially when viewed from a biopolitical perspective, force one to focus on the structures of the relations between all that participates in the enfolding case study. Argentina is an extraordinary laboratory in the domain of struggle against impunity and of 'restoration of the truth'. It constitutes a useful paradigm in the context of reflection on the corpses of mass violence. Its special character, in the immediate aftermath of the military dictatorship, is to test almost the entirety of juridical mechanisms in the handling of state crimes. The trigger for both the intercommunal violence and the civil war was the mass murders by the Ustaša. This book discusses the massacres carried out by the Ustaša in Croatia during the Second World War. After a brief presentation of the historical background, the massacres carried out by the Ustaša militia and their corpse disposal methods are described. Using Rwanda as a case study, the book proposes an agenda for ethnographic research to explore the relationship between concealment and display in contexts of genocide. This relationship is explored in detail after a discussion of the historical background to the 1994 genocide.
