The Irish Citizen Army (Irish language: Arm Cathartha na hÉireann ), or ICA, was a small group of trained trade union volunteers established in Dublin for the defence of worker's demonstrations from the police. It was formed by James Larkin, James Connolly and Jack White. Other prominent members included Seán O'Casey, Constance Markievicz, Francis Sheehy-Skeffington and P. T. Daly. In 1916, it took part in the Easter Rising – an armed insurrection aimed at ending British rule in Ireland.

The Lockout

The army rose out of the great strike of the Irish Transport and General Workers Union in 1913, known as the Lockout of 1913. The dispute was over the recognition of this labour union founded by James Larkin. It began when William Martin Murphy, an industrialist, locked out some trade unionists on 19 August 1913. In response, Larkin called an all out strike on Murphy's Dublin United Tramway Company. Other companies, encouraged by Murphy, sacked ITGWU members in an effort to break the union. The conflict eventually escalated to involve 400 employers and 25,000 workers.

This strike caused most of Dublin to come to an economic standstill and was marked by vicious rioting between the strikers and the Dublin Metropolitan Police, particularly at a rally on O'Connell Street on 31 August, in which two men were beaten to death and about 500 more injured. Another striker was later shot dead by a strike-breaker. The violence at union rallies during the strike prompted Larkin to call for a workers' militia to be formed to protect themselves against the police. The Citizen army for the duration of the lock-out was armed with hurleys (sticks used in hurling, a traditional Irish sport) and bats to protect workers' demonstrations from the police. Jack White, a former British Army Captain, volunteered to train this army and offered 50 pounds towards the cost of shoes to workers so they could train. In addition to its role as a self-defence organisation, the army, which was drilled in Croydon Park in Fairview by White, provided a diversion for workers unemployed and idle during the dispute. After a six-month standoff, the workers returned to work hungry and defeated in January 1914. The original purpose of the ICA was over, but it would soon be totally transformed.

The Irish Citizen Army underwent a complete reorganisation in 1914.[1] In March of that year, police attacked a demonstration of the Citizen Army and arrested Jack White, its commander. Sean O'Casey then suggested that the ICA needed a more formal organisation. O'Casey wrote a constitution, stating the Army's principles as follows: "the ownership of Ireland, moral and material, is vested of right in the people of Ireland" and to "sink all difference of birth property and creed under the common name of the Irish people".[1]

Larkin insisted that all members also be members of a trade union, if eligible. In mid-1914, White resigned as ICA commander to join the mainstream nationalist Irish Volunteers, and Larkin took over.

James Larkin left Ireland for America in October 1914, leaving the Citizen Army under the command of James Connolly. Whereas during the Lockout, the ICA had been a workers' self-defence militia, Connolly conceived of it as a revolutionary organisation – dedicated to the creation of an Irish socialist republic. He had served in the British army in his youth and knew something about military tactics and discipline. Other active members in the early days included Sean O'Casey, Constance Markievicz, Francis Sheehy-Skeffington. Sheehy-Skeffington and O'Casey left the ICA when it became apparent that Connolly had started gravitating towards the radical nationalist group, the Irish Republican Brotherhood.

James Connolly, a convinced Marxist socialist and Irish Republican, believed that achieving political change through physical force, in the tradition of the Fenians, was legitimate.

The ICA armed itself with Mauser rifles bought from Germany by the Irish Volunteers and smuggled into Ireland at Howth in July 1914. This organisation was one of the first to offer equal membership to both men and women and trained them both in the use of weapons. The army's headquarters was the ITGWU union building, Liberty Hall and membership was almost entirely Dublin based. However, Connolly also set up branches in Tralee and Killarney in County Kerry. In October 1915, armed ICA pickets patrolled a strike by dockers at Dublin port.

Appalled by the participation of Irishmen in the First World War, which he regarded as an imperialist, capitalist conflict, Connolly began openly calling for insurrection in his newspaper, the Irish Worker. When this was banned he opened another, the Worker's Republic.

An armed organisation of the Irish working class is a phenomenon in Ireland. Hitherto the workers of Ireland have fought as parts of the armies led by their masters, never as a member of any army officered, trained and inspired by men of their own class. Now, with arms in their hands, they propose to steer their own course, to carve their own future.

British authorities tolerated the open drilling and bearing of arms by the ICA, thinking that to clamp down on the organisation would provoke further unrest. A small group of Irish Republican Brotherhood (IRB) conspirators within the Irish Volunteers movement had started planning a rising. Worried that Connolly would embark on premature military action with the ICA, they approached Connolly and inducted him into the IRB's Supreme Council to co-ordinate their preparations for the armed rebellion which became known as the Easter Rising.

The army never numbered more than 250 men and women. On Monday, 24 April 1916, 220 of them (including 28 women) took part in the Easter Rising, alongside a much larger body of the Irish Volunteers. They helped occupy the General Post Office on O'Connell Street (then Sackville Street), Dublin's main thoroughfare. Mallin, Connolly's second in command, along with Markievicz and an ICA company, occupied St Stephen's Green. Another company under Sean Connolly took over City Hall and attacked Dublin Castle. Finally, a detachment occupied Harcourt Street railway station. ICA men were the first rebel casualties of Easter Week, two of them being killed in an abortive attack on Dublin Castle.

Sean Connolly, an ICA officer and Abbey Theatre actor, was both the first rebel to kill a British soldier and the first to be killed.[2]

A total of eleven Citizen Army men were killed in action in the rising, five in the City Hall/Dublin castle area, five in Stephen's Green and one in the GPO.[citation needed]

James Connolly was made commander of the rebel forces in Dublin during the Rising and issued orders to surrender after a week. He and Mallin were executed by British army firing squad some weeks later. The surviving ICA members were interned in Frongoch in Wales and in English prisons for nine to 12 months.

Many of them later joined the new Irish Republican Army (IRA) at various times, but the Citizen Army under Connolly's elected successor, chief Rising bomb-maker and builder James O'Neill, took command of Dublin county two miles either side of the Liffey River and Kildare as far as Maynooth during the War of Independence ending in the Treaty of 1922 when 26 of the 32 Irish counties became the Free State. O'Neill was also joint intelligence and logistics chief under Michael Collins' IRA. RM Fox, The Irish Citizen Army official history. O'Neill and ICA units were involved in various IRA operations during the War of Independence, including the burning of the Customs House in May 1921 and rescue of IRA arms after. During the fighting in Dublin that began the Irish Civil War in July 1922, some elements of the ICA (which by this time had about 140 members) were involved in the Anti-Treaty IRA occupation and defence of the Four Courts while others occupied Liberty Hall, the Trade Union headquarters, to prevent it falling into the hands of either the Republicans or the Free State Army.

Post-Irish independence

In the 1920s and 1930s, the ICA was kept alive by veterans such as Seamus McGowan, Dick McCormick and Frank Purcell, though largely as an old comrades association by veterans of 1916.

Uniformed Citizen Army men provided a guard of honour at Constance Markievicz's funeral in 1927.

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 ICA as a paramilitary force, intended to be an armed wing for their new movement. According to Brian Hanley's history of the IRA, the revived Citizen Army had 300 or so members around the country in 1935. However, the Congress itself split in 1935 and collapsed shortly afterwards.

The ICA's last public appearance was to accompany the funeral procession of union leader James Larkin in Dublin in 1947.

Uniforms and banners

Starry Plough, 1930s to present.

The ICA uniform was dark green with a slouched hat and badge in the shape of the Red Hand of Ulster.[3] As many members could not afford a uniform, they wore a blue armband, with officers wearing red ones.[citation needed]

Their banner was the Plough and the Stars. Connolly said the significance of the banner was that a free Ireland would control its own destiny from the plough to the stars. The symbolism of the flag was evident in its earliest inception of a plough with a sword as its blade. Taking inspiration from the bible and following the internationalist aspect of socialism it reflected the belief that war would be redundant with the rise of the Socialist International. This was flown by the Irish Citizens Army during the 1916 rising. The design changed during the 1930s to that of the blue banner on the left, which was designed by members of the Republican Congress, and was adopted as the emblem of the Irish Labour movement, including the Irish Labour Party, though they eventually dropped it. It is also claimed by Irish republicans and has been carried alongside the Irish tricolour and Irish provincial flags at Continuity Irish Republican Army, Provisional IRA, Official IRA and Irish National Liberation Army (INLA) rallies.

The banner, and alternative versions of it, is also used by the Connolly Youth Movement, Labour Youth, Ógra Shinn Féin and the Republican Socialist Youth Movement.
