This is a timeline of the Irish Civil War, which took place between June 1922 and May 1923. It followed the Irish War of Independence (1919–1921), and accompanied the establishment of the Irish Free State as an entity independent from the United Kingdom of Great Britain and Ireland. The conflict was waged between two opposing groups of Irish nationalists: the forces of the new Irish Free State, who supported the Anglo-Irish Treaty under which the state was established, and the republican opposition, for whom the Treaty represented a betrayal of the Irish Republic. The government of the Irish Free State (established as a provisional government in January 1922 and as a full government in December 1922) was ultimately victorious. The anti-Treaty forces called a ceasefire in April 1923 and ordered their men to "dump arms" in May 1923. The war involved both conventional warfare (late June–August 1922) when the Free State forces took the major towns and cities, and then a longer period of guerrilla warfare (September 1922 – April 1923) as the anti-Treaty forces were gradually brought to a standstill.

Appendix

Statistics are incomplete, Free State government sources stated that between 540 and 800 National Army soldiers were killed in the war. Historian Michael Hopkinson, in Green against Green, pp. 272–3, states "There are no means by which to arrive at even approximate figures for the dead and wounded. Mulcahy stated that around 540 pro-Treaty troops were killed between the Treaty's signing and the war's end; the government referred to 800 army deaths between January 1922 and April 1924. There was no record of overall Republican deaths, which appear to have been very much higher. No figure exists for total civilian deaths."

Deaths by date

Anti-Treaty combatants killed in Clare: 28 (no reliable statistics for pro-Treaty/Civilians). Pro/Anti-Treaty combatants killed between January–June 1922, 9, – 2 in Clare. Casualties in County Kildare, 45 killed. (17 National Army) Additions,: Kerry + 78, Cork + 120, Sligo + 39, Offaly + 19, Clare + 27, January–June clashes + 7 = 290 Revised total: 1,147-1,251* A range is given where casualties are reported but not confirmed.

• this is not a definitive total, but rather what could be found in this article.
