From the founding of the Irish Citizen Army (ICA) to Easter Week 1916 can be described as the organisation’s heroic period. It would survive the Rising by a further twenty years: until the Civil War in form and occasional actions and campaigns, then in suspended animation until 1934, and reviving for one more year before dissolving to form the nucleus of the left wing of the Dublin Labour Party, almost exactly 22 years after its foundation.

The Irish Citizen Army (Irish: Arm Cathartha na hÉireann), or ICA, was a small paramilitary group of trained trade union volunteers from the Irish Transport and General Workers' Union (ITGWU) established in Dublin for the defence of workers' demonstrations from the Dublin Metropolitan Police. It was formed by James Larkin, James Connolly and Jack White on 23 November 1913.[1] Other prominent members included Seán O'Casey, Constance Markievicz, Francis Sheehy-Skeffington, P. T. Daly and Kit Poole. In the 1920s and 1930s, The Irish Citizen Army was kept alive by veterans such as Seamus McGowan, Dick McCormick and Frank Purcell, though largely as an old comrades association by veterans of the Easter Rising. In 1934, Peadar O'Donnell and other left-wing republicans left the IRA and founded the Republican Congress. For a brief time, they revived The Irish Citizen Army as a paramilitary force, intended to be an armed wing for their new movement. However, the Congress itself split in September 1934, which led to a corresponding split in The Irish Citizen Army.
