This dataset is created for a study of the association between International Criminal Court (ICC) investigations and fatalities of organised violence. It links fatalities statistics from the Uppsala Conflict Data Program to data on UN peacekeeping operations, ICC investigations and unilateral operation by great powers (UNSC P5). Specifically, it contains monthly data on fatalities from 1998–2020 in countries in which the ICC was conducting investigations, and the timeline of the aforementioned interventions in those countries. It also contains per-country graphs of the data for the Central African Republic, the Democratic Republic of Congo, Libya, and Palestine.

Definitions and data are further explained and justified in the associated publication, "The International Criminal Court and Organised Violence" by Mattia Cacciatori and Timo Kivimäki.
