Mass Atrocity Endings Research
How do mass atrocities end?
The WPF program on mass atrocities, defined as widespread and systematic violence against civilians (2011 – 2021), primarily focused on studying patterns of endings. In this program, ‘endings’ includes analysis of patterns of de-escalation of direct, lethal violence and other forms of harming civilians, and the study of recurrence in the context of global trends. The focus was determined by two interests: first, the impact of organized violence on civilian populations, and second, concern that conventional narratives of ending atrocities through military intervention were inadvertently lowering the bar for military intervention by adding a human rights based argument to buttress militarism.

The existing conventional meta-narrative for genocide and mass atrocity against civilians is empirically and analytically strong on the origins and nature of such extreme violence, but takes a strictly normative turn when considering the endings of genocide or mass atrocity. The ‘ideal’ ending, which tends to preoccupy advocates and policymakers, consists of an international military intervention leading to a settlement that includes not only an end to genocide but also the establishment of peace and democracy along with an exercise in transitional justice that may include trials, assistance to the survivors, memorialization, compensation and reparation. What debates do exist generally focus on the legality and politics of international interventions to halt genocide and measures to bring perpetrators to justice. This project explored the oft-neglected empirical study of how genocides and mass atrocities have actually terminated. The program concluded in 2021.
