This chapter seeks to examine the nature and some key forms of remembering and forgetting violence in the twentieth century. Through considering a range of sites of memory linked to specific acts of violence, we explore the shifting nature of remembrance. The violent pasts, and presents, that we examine include world wars, civil wars, the Holocaust, colonization, child sexual abuse and the place of gender in violence. In particular we focus on bodies, pilgrimages, memorials, truth and reconciliation processes, and public apologies to reveal the variety of ways historical and ongoing violence is brought to the fore in the public sphere. We also reflect upon the ways remembering and forgetting violence in the world has been transformed by novel developments in technologies, particularly DNA testing, as well as radically reformed through personal and political activism and shifting ideological demands. The impacts of these influences can be seen in examples of cultural practices that have changed over time. Through these explorations we can see the range of ways the legacies of violence are remembered, and the work violence can do when it is remembered and forgotten in the world today.
