This dataset is created for a study that investigates the track record of the International Criminal Court's investigations for their association with the increase or decrease of fatalities of organised violence. The study that is based on this data also investigates whether the partnering of ICC operations with the UN or with unilateral great powers affects this track record. The data relies on Uppsala Conflict Data Program data concerning fatalities of organised violence, transforms it into monthly data and merges it with the timelines of ICC, UN and unilateral operations.
