The executions during the Irish Civil War took place during the guerrilla phase of the Irish Civil War (June 1922 – May 1923). This phase of the war was bitter, and both sides, the government forces of the pro-treaty Irish Free State and the anti-Treaty Irish Republican Army (IRA) insurgents, used executions and terror in what developed into a cycle of atrocities. From November 1922, the pro-treaty provisional later Free State government embarked on a policy of executing Republican prisoners in order to bring the war to an end. Many of those killed had previously been allies, and in some cases close friends (during the Irish War of Independence 1919–1921), of those who ordered their deaths in the civil war. In addition, government troops also summarily executed at least 130 prisoners in the field. The executions of prisoners left a lasting legacy of bitterness in Irish politics.
The use of execution by the Irish Free State in the Civil War was relatively harsh compared to the recent British record. In contrast with 81 official executions by the Irish Free State government, the British had executed 24 IRA volunteers during the 1919–21 conflict.[1]
