The Irish Civil War Fatalities Project, supported with funding from the Department of Tourism, Culture, Arts, Gaeltacht, Sport and Media, seeks to identify all of the conflict-related fatalities in Ireland between the opening shots of the Civil War on 28 June 1922 and the ceasefire and dump arms order on 24 May 1923.

For decades, historians of the Civil War have resorted to estimates when surveying the human cost of Ireland's Civil War. Now, for the first time, UCC historian Dr Andy Bielenberg, assisted by John Dorney, has enumerated the civilian and combatant fatalities, allowing for a wide-ranging, sometimes surprising, analysis of the nature and geographic distribution of the casualties and their impact.

In collaboration with UCC’s Atlas of the Irish Revolution Team, the research findings have been cartographically represented in a searchable, interactive Civil War Fatalities map.

The Fatalities map, index and contextualising articles represent an important legacy project of the Decade of Centenaries. It will be a vital tool for looking objectively at this complex period in Irish history and will help researchers trace both the wider patterns of the conflict and the very real cost to individuals. It provides accessible, accurate data – filling in gaps in our knowledge about the Civil War – while also offering invaluable support for people seeking, in Dr Maurice Manning’s words, ‘to navigate their own personal commemorative paths’.
