Irish Republican Army (1917–22)

The Irish Republican Army (IRA) (Irish: Óglaigh na hÉireann) was an Irish republican revolutionary military organisation. The ancestor to many groups also known as the Irish Republican Army, it was descended from the Irish Volunteers, an organisation established on 25 November 1913 that staged the Easter Rising in April 1916. In 1919, the Irish Republic that had been proclaimed during the Easter Rising was formally established by an elected assembly (Dáil Éireann), and the Irish Volunteers were recognised by Dáil Éireann as its legitimate army. Thereafter, the IRA waged a guerrilla campaign against the British occupation of Ireland in the 1919–21 Irish War of Independence.
