The I.R.B.

Easter Proclamation of 1916

The Irish Republican Brotherhood (I.R.B.) was a secret oath-bound fraternal organisation dedicated to the establishment of an “independent democratic republic” in Ireland between 1858 and 1924. Founded in the United States by John O’Mahony, James Stephens and Michael Doheny at Doheny’s Law Offices, Centre St, New York,  March 17th 1858. It became known as the Fenian Brotherhood (later Clan na Gael). James Stephens subsequently returned to Dublin and founded the Irish Republican Brotherhood (I.R.B.). The members of both wings of the movement are often referred to as “Fenians”. (the three had been members of Young Ireland and attended the Council of war in Ballingarry on Friday 26th July 1848. ‘See Young Ireland’)

(Sequel to the Young Ireland Uprising);   After the failure of the Rising, O’Brien, Thomas Francis Meagher, Terence Bellew MacManus and Patrick O’Donohue were captured and tried for high treason.  Juries found them guilty but recommended mercy. Nevertheless they were sentenced to death by hanging, drawing and quartering. They refused to appeal.

 The sentences were, however, commuted by a special act of parliament to penal imprisonment for life in Van Diemen’s Land (now Tasmania) in Australia. There, they were joined by Young Ireland colleagues –  John Martin, Kevin Izod O’Doherty and John Mitchel. Mitchel had been convicted of treason-felony and sentenced to fourteen years transportation in May 1848. Twenty-one locals from Ballingarry and the surrounding parishes were also arrested and jailed in Ireland. Other Young Irelanders escaped to France and the USA.
John Blake Dillon returned from America and died as Member of Parliament for County Tipperary in 1866. James Stephens, John O’Mahony and Michael Doheny  co-founded the Irish Republican Brotherhood (I.R.B) or Fenian movement in 1858. The IRB later organised the unsuccessful Rising of 1867 and the 1916 Rising which ultimately lead to Irish independence.


During the young Ireland revolution of 1848, nine young Irishmen were captured, tried and convicted of treason against the Queen. The sentence was death. The Presiding Judge read out the names of the condemned men Charles Gavin Duffy. Thomas Francis Meagher. Patrick Donahue. Tcrence McManus, Richard 0’Gorman, Morris Lyene, Michael Ireland, Thomas Darcy McGee & John Mitchell. “Have you anything to say before the court passes sentence?” Thomas Meagher had been chosen to speak for them all “My Lord this is our first offence, but not our last, if you will be easy wtth us this once, we promise on our word as gentlemen to try to do better the next tine, and the next time sure we won’t be fools enough to get caught.” The indignant judge sentenced them to be hanged by the neck. but passionate protests from all over the world forced Queen Victoria to commute the sentence, the men were transported for life to the penal colony of the then savage Australia.

– In 1871 a Sir Charles Duffy was elected Prime Minister of the Australian state of Victoria.

To her amazement Queen Victoria learned from her Prime Minister Disraeli that this was the same Charles Duffy who bad been transported for treason 23 years before. She demanded the records of the other eight convicts and this is what she learned.

– Thomas Francis Meagher was Governor of Montana.

– Patrick Donahue and Terence McManus were Brigadier Generals in the US. Army,

– Richard O’Gorman was Governor General of Newfoundland.

– Morris Leyne was Attorney General of Australia

– To which office Michael Ireland succeeded.

– Thomas d’Arcy McGee was President of the Dominion of Canada

– John Mitchell was elected MP for Tipperary to the British House of Commons,

only to be disqualified because he was a convicted felon.

This amazing true story of nine men banished from their native land to a penal colony for their political views, and in later years becoming outstanding citizens in America, Australia, and Canada, is now a part of the United States

On the other hand, John Mitchel supported the south in the same war. He was later elected Member of Parliament for Co. Tipperary in 1875, the year of his death. MacManus died in San Francisco in 1861 and was accorded a famous funeral in Ireland. Kevin Izod O’Doherty on his release served as a member of the Queensland legislature in Australia and later as an Irish M.P. Charles Gavan Duffy whom the government failed to convict at trial, re-opened the Nation which had been suppressed during the Rebellion, and became an M.P.
He emigrated to Australia where he became Premier of the State of Victoria in 1871. Duffy later became the historian of the Young Ireland movement. John Martin following his release became a Home Rule M.P. William Smith O’Brien was incarcerated on Maria Island, off the coast of Tasmania, and then in a two-roomed cottage (now the O’Brien Museum) within the Port Arthur penal colony. He received a conditional pardon in 1854 which was made unconditional in 1856 and allowed him to return to Ireland. He refused many offers from Irish constituencies to return to the House of Commons. He died in 1864 and is buried in the O’Brien mausoleum, Rathronan, Co. Limerick. His statue stands on O’Connell Street, Dublin.)

The IRB played an important role in the history of Ireland, as the chief advocate of republicanism during the campaign for Ireland’s independence from the United Kingdom, successor to movements such as the United Irishmen of the 1790s and the Young Irelanders of the 1840s. As part of the New Departure of the 1870s–80s, IRB members attempted to democratise the Home Rule League, and its successor, the Irish Parliamentary Party, as well as taking part in the Land War. The IRB staged the Easter Rising in 1916, which led to the establishment of the first Dáil Éireann in 1919. The suppression of Dáil Éireann precipitated the Irish War of Independence and the signing of the Anglo-Irish Treaty in 1921, ultimately leading to the establishment of the Irish Free State, which excluded the territory of Northern Ireland.

Thomas Osborne Davis In 1798 the United Irishmen, which had initially been an open political organisation, but which was later suppressed by the British establishment in Ireland and so became a secret revolutionary organisation, rose in rebellion, seeking an end to British rule in Ireland and the establishment of an Irish Republic. The rebellion was suppressed, but the principles of the United Irishmen were to have a powerful influence on the course of Irish history. Following the collapse of the rebellion, the British prime minister William Pitt introduced a bill to abolish the Irish parliament and manufactured a Union between Ireland and Britain. Opposition from the Protestant oligarchy that controlled the parliament was countered by the widespread and open use of bribery. The Act of Union was passed, and became law on 1 January 1801. The Catholics, who had been excluded from the Irish parliament, were promised emancipation under the Union. This promise was never kept, and caused a protracted and bitter struggle for civil liberties. It was not until 1829 that the British government reluctantly conceded Catholic emancipation.

Though leading to general emancipation, this process simultaneously disenfranchised the small tenants, known as ‘forty shilling freeholders’, who were mainly Catholics. Daniel O’Connell, who had led the emancipation campaign, then attempted the same methods in his campaign, to have the Act of Union with Britain repealed. Despite the use of petitions and public meetings which attracted vast popular support, the government thought the Union was more important than Irish public opinion. During the early 1840s, the younger members of the repeal movement became impatient with O’Connell’s over-cautious policies, and began to question his intentions. Later they were what came to be known as the Young Ireland movement. In 1842 three of the Young Ireland leaders,

Thomas_Davis_Young_IrelanderThomas Davis, Charles Gavan Duffy and John Blake Dillon, launched the Nation newspaper. In the paper they set out to create a spirit of pride and an identity based on nationality rather than on social status or religion. Following the collapse of the Repeal Association and with the arrival of famine, the Young Irelanders broke away completely from O’Connell in 1846. John Mitchel The blight that destroyed the potato harvest between 1845 and 1849 was an unprecedented human tragedy. An entire social class of small farmers and labourers were to be virtually wiped out by hunger, disease and emigration. The laissez –faire economic thinking of the government ensured that help was slow, hesitant and insufficient. Between 1845 and 1851 the population fell by almost two million. That the people starved while livestock and grain continued to be exported, quite often under military escort, left a legacy of bitterness and resentment among the survivors. The waves of emigration because of the famine and in the years following, also ensured that such feelings were not confined to Ireland, but spread to England, the United States, Australia, and every country where Irish emigrants gathered. Shocked by the scenes of starvation and greatly influenced by the revolutions then sweeping Europe, the Young Irelanders moved from agitation to armed rebellion in 1848. The attempted rebellion failed after a small skirmish in Ballingary, Co Tipperary, coupled with a few minor incidents else where. The reasons for the failure were obvious, the people were totally despondent after three years of famine, having been prompted to rise early resulted in an inadequacy of military preparations, which caused disunity among the leaders. The government quickly rounded up many of the instigators, those who could, fled across the seas, and their followers dispersed. A last flicker of revolt in 1849, led by among others James Fintan Lalor, was equally unsuccessful. John Mitchel, the most committed advocate of revolution, had been arrested early in 1848 and transported to Australia on the purposefully created charge of Treason-felony. He was to be joined by other leaders, such as William Smith O’Brien and Thomas Francis Meagher who had both been arrested after Ballingary, John Blake Dillon escaped to France, as did three of the younger members, James Stephens, John O’Mahony and Michael Doheny.  

James Stephens James Stephens (1824–1901) After the collapse of the 1848 rebellion James Stephens and John O’Mahony went to Europe to avoid arrest. In Paris they supported themselves through teaching and translation work and planned the next stage of “the fight to overthrow British rule in Ireland.” Stephens in Paris, set himself three tasks, during his seven years of exile. They were, to keep alive, pursue knowledge, and master the technique of conspiracy. At this time Paris particularly, was interwoven with a network of secret political societies. They became members of one of the most powerful of these societies and acquired the secrets of some of the ablest and “most profound masters of revolutionary science” which the 19th century had produced, as to the means of inviting and combining people for the purposes of successful revolution. In 1853, O’Mahony went to America and founded the Emmet Monument Association. In early 1856, Stephens began making his way back to Ireland, stopping first in London. On arriving in Dublin, Stephens began what he described as his three thousand mile walk through Ireland, meeting some of those who had taken part in the 1848/49 revolutionary movements, including

Philip Gray, Thomas Clarke Luby and Peter Langan. In the autumn of 1857, a messenger, Owen Considine arrived from New York with a message for Stephens from members of the Emmet Monument Association, calling on him to get up an organisation in Ireland. Considine also carried a private letter from O’Mahony to Stephens which was a warning as to the condition of the organisation in New York, which was overseen by Luby and Stephens at the time. Both had believed that there was a strong organisation behind the letter, only later to find it was a number of loosely linked groups.   John O’Mahony (1816–1877) On 23 December Stephens dispatched Joseph Denieffe to America with his reply which was disguised as a business letter, and dated and addressed from Paris. In his reply Stephens outlined his conditions and his requirements from the organisation in America. Stephens demanded uncontrolled power and £100 a month for the first three months. Denieffe returned on 17 March 1858 with the acceptance of Stephens terms and £80. Denieffe also reported that there was no actual organised body of sympathisers in New York but merely a loose knot of associates. This disturbed Stephens but he went ahead regardless and that evening, St. Patrick’s Day, the Irish Republican Brotherhood commenced. The original oath, with its clauses of secrecy was drawn up by Luby under Stephens’ direction in Stephens’ room in Donnelly’s which was situated behind Lombard Street. Luby then swore Stephens in and he did likewise. Those present in Langan’s, lathe-maker and timber merchant, 16 Lombard Street for that first meeting apart from Stephens and Luby were Peter Langan, Charles Kickham, Joseph Denieffe and Garrett O’Shaughnessy. Later it would include members of the Phoenix National and Literary Society, which was formed in 1856 by Jeremiah O’Donovan Rossa in Skibbereen.  The IRB was organised into circles, a “circle” was analogous to a regiment, that the “centre” or A, who might be considered equivalent to a colonel, who chose nine B’s, or captains, who in their turn chose nine C’s, or sergeants, who in their turn chose nine D’s, who constituted the rank and file. In theory an A should only be known to the B’s; a B, to his C’s: and a C, to his D’s; but this rule was often violated. 


Thomas_Clarke_LubyThomas Clarke Luby:  Dublin Castle was the seat of government administration in Ireland and was appointed by the British cabinet and was accountable only to the cabinet, not to the House of Commons and not to the Irish people or their political representatives. Irish MPs could speak at Westminster in protest about the actions of the administration, but its privileges were unchallengeable as Irish representation in the House of Commons was only one sixth of the total and far too small. Fenianism therefore, according to O’Mahony is symbolised by two principles: Firstly, that Ireland had a natural right to independence, and secondly, that that right could be won only by an armed revolution.  Because of their belief in republicanism, that is, the “common people are the rightful rulers of their own destiny,” the founding members saw themselves as “furious democrats in theory” and declared their movement to be “wholly and unequivocally democratic.” Being a democrat and egalitarian in the mid 19th century was tantamount to being a revolutionary, and was something to be feared by political establishments.  It was Stephens “firm resolution to establish a democratic republic in Ireland; that is, a republic for the weal of the toiler,”  and that this would require a complete social revolution before the people could possibly become republicans.  In propagating republican principles, they felt, the organisation would create this virtual democracy within the country, which would form the basis of an independence movement.  The Fenians soon established themselves in Australia, South America, Canada and, above all, in the United States, as well as in the large cities of England, such as London, Manchester, Liverpool, and Glasgow, in Scotland.

The oath

Joseph_DenieffeJoseph Denieffe The original IRB oath, as quoted by Thomas Clarke Luby and John O’Leary, and which is among several versions in James Stephens’s own papers, ran: “I, AB., do solemnly swear, in the presence of Almighty God, that I will do my utmost, at every risk, while life lasts, to make [other versions, according to Luby, establish in’] Ireland an independent Democratic Republic; that I will yield implicit obedience, in all things not contrary to the law of God [‘laws of morality’] to the commands of my superior officers; and that I shall preserve inviolable secrecy regarding all the transactions [ ‘affairs’] of this secret society that may be confided in me. So help me God! Amen.  This oath was significantly revised by Stephens in Paris in the summer of 1859. He asked Luby to draw up a new text, omitting the secrecy clause. The omitting of the secrecy clause was outlined in a letter from Stephen’s to John O’Mahony on 6 April 1859 and the reasons for it. ‘Henceforth,’ wrote Luby to O’Leary “we denied that we were technically a secret body. We called ourselves a military organization; with, so to speak, a legionary oath like all soldiers.” The revised oath ran:

“I, A.B, in the presence of Almighty God, do solemnly swear allegiance to the Irish Republic, now virtually established; and that I will do my very utmost, at every risk, while life lasts, to defend its independence and integrity; and, finally, that I will yield implicit obedience in all things, not contrary to the laws of God (or ‘the laws of morality’), to the commands of my superior officers. So help me God. Amen’. 

In yet a later version it read:

In the presence of God, I, …, do solemnly swear that I will do my utmost to establish the independence of Ireland, and that I will bear true allegiance to the Supreme Council of the Irish Republican Brotherhood and the Government of the Irish Republic and implicitly obey the constitution of the Irish Republican Brotherhood and all my superior officers and that I will preserve inviolable the secrets of the organisation. Supreme Council”

The IRB was re-organised at a convention in Manchester in July 1867. An 11-man Supreme Council was elected to Govern the movement.  They would eventually be representatives from the seven districts in which the organisation was organised: the Irish provinces of Ulster, Munster, Leinster and Connacht, as well as Scotland, North England, and South England. The remaining four members were co-opted. The Supreme Council elected three of its members to the executive, which consisted of a president, secretary, and a treasurer. The Council met twice a year, usually in the spring and the summer. In Manchester August 1867 Thomas Kelly was declared Chief Organiser of the Irish Republic (COIR), in succession to Stephens.

The arrest and subsequent rescue of Kelly with Timothy Deasy in September 1867 resulted in the execution of the Manchester Martyrs. Kelly escaped to USA and remained associated with the U.S. Branch of the Irish Republican Brotherhood.  After Stephen’s  formation of the Brotherhood in Ireland and while the Irish nationalists groups in the United States remained uncohered, Bernard McNulty a close friend and political associate of John Boyle O’Reilly established a U.S. branch for the Irish Republican Brotherhood. This branch was quickly co-opted when John O’Mahony was, finally, able to actually organize or force a unification of the other Irish nationalist organizations in the United States under the umbrella of (really to also co-opt them into) the quickly enormously popular and numerously membered, newly, formed and independent, U.S. Fenian Brotherhood, with which the Irish Republican Brotherhood thereafter exclusively coordinated its activities. 

The movement was denounced by the British establishment, the press, the Catholic Church and Irish political elite, as had been all Irish separatist and Republicanism movements. The Tories, disturbed by the increase in republican propaganda, particularly in America, launched a propaganda campaign in the Irish press to discredit the American Fenians. They presented them as enemies of Catholicism quoting negative comments by some American Catholic bishops. As in Irish-America, likewise Ireland and England, the Catholic hierarchy felt the growth of nationalist politics among Irishmen was essentially dangerous. Therefore during the 1860s and succeeding decades, the upper or middle classes who controlled the Irish press were very apprehensive in the growth of democratic politics in Ireland, which represented to them a threat of anarchy and revolution.  It was feared that if Britain was given any reason to renew coercion, Catholic interests in both Ireland and England would be undermined. In addition, the small class of Irish Catholic merchants, lawyers and gentry who had prospered under the Union felt anxious for the same reasons.

By 1864, the Tories had coined the phrase ‘Fenianism’ to describe all that was considered potentially bothersome among Irishmen on both sides of the Atlantic.  Fenianism as a term was then used by the British political establishment to depict any form of mobilisation among the lower classes and, sometimes, those who expressed any Irish nationalist sentiments. They warned people about this threat to turn decent civilised society on its head such as that posed by trade unionism to the existing social order in England.  The same term was taken up by members of the Irish Catholic hierarchy, who also began denouncing “Fenianism” in the name of the Catholic religion.  One Irish Bishop, David Moriarty of Kerry, declared that “when we look down into the fathomless depth of this infamy of the heads of the Fenian conspiracy, we must acknowledge that eternity is not long enough, nor hell hot enough to punish such miscreants.

Denis Dowling Mulcahy, Thomas Clarke Luby and John O’Leary

Denis Dowling Mulcahy, Thomas Clarke Luby and John O'LearyIn mid-1863 Stephens informed his colleagues he wished to start a newspaper, with financial aid from O’Mahony and the Fenian Brotherhood in America. The offices were established at 12 Parliament Street, almost at the gates of Dublin Castle. The first edition of the Irish People appeared on 28 November 1863.  The staff of the paper along with Kickham were Luby and Denis Dowling Mulcahy as the editorial staff. O’Donovan Rossa and James O’Connor were in charge of the business office, with John Haltigan being the printer. John O’Leary was brought from London to take charge in the role of Editor.  Shortly after the establishment of the paper, Stephens departed on an American tour, and to attend to organisational matters.  American Fenians made plans for a rising in Ireland, but the plans were discovered on 15 July 1865 when an emissary lost them at Kingstown railway station. They found their way to Dublin Castle and to Superintendent Daniel Ryan head of G Division. Ryan had an informer within the offices of the Irish People named Pierce Nagle, he supplied Ryan with an “action this year” message on its way to the IRB unit in Tipperary. With this information, Ryan raided the offices of the Irish People on Thursday 15 September, followed by the arrests of O’Leary, Luby and O’Donovan Rossa. The last edition of the paper is dated 16 September 1865.  

Stephens entrusted to Luby a document containing secret resolutions on the Committee of Organization or Executive of the IRB. Though Luby intimated its existence to O’Leary, he did not inform Kickham as there seemed no necessity. This document would later form the basis of the prosecution against the staff of the Irish People. The document read: 

EXECUTIVE I hereby appoint Thomas Clarke Luby, John O’Leary and Charles J. Kickham, a Committee of Organization or Executive, with the same supreme control over the Home Organization (Ireland, England, Scotland, etc.) I have exercised myself. I further empower them to appoint a Committee of Military Inspection, and a Committee of Appeal and Judgment, the functions of which Committee will be made known to each member of them by the Executive. Trusting to the patriotism and ability of the Executive, I fully endorse their action beforehand, and call on every man in our ranks to support and be guided by them in all that concerns our military brotherhood. 9 March 1864, Dublin; J. STEPHENS

Kickham was caught after a month on the run. Stephens would also be caught, but with the support of Fenian prison warders, John J. Breslin  and Daniel Byrne was less than a fortnight in Richmond Bridewell when he vanished and escaped to France.  In 1882, a breakaway IRB faction calling itself the Irish National Invincibles assassinated the British Chief Secretary for Ireland Lord Frederick Cavendish and his secretary, in an incident known as the Phoenix Park Murders.  In March 1883 the London Metropolitan Police’s Special Irish Branch was formed, initially as a small section of the Criminal Investigation Department, to monitor IRB activity.

Twentieth century  

Michael Collins, the last president of the IRB By the start of the 20th century, the IRB was a stagnating organisation, concerned more with Dublin municipal politics than the establishment of a republic according to F. S. L. Lyons. A younger generation of Ulster republicans aimed to change this, and in 1905 Denis McCullough and Bulmer Hobson founded the Dungannon Clubs. Inspired by the Volunteers of 1782, the purpose of these clubs was to discourage enlistment into the British Army, and encourage enlistment into the IRB, with the overall goal of complete independence from Britain in the form of an Irish Republic.  They were joined by Sean MacDermott, and in 1908 he and Hobson relocated to Dublin, where they teamed up with veteran Fenian Tom Clarke. Clarke had been released from Portland Prison in October 1898 after serving fifteen and a half years, and had recently returned to Ireland after living in the United States. Sent by John Devoy and the Clan na Gael to reorganise the IRB, Clarke set about to do just that. 

In 1909 the young Michael Collins was introduced to the brotherhood by Sam Maguire. By 1914 the Supreme Council was largely purged of its older, tired leadership, and was dominated by enthusiastic men such as Hobson, McCullough, Patrick McCartan, John MacBride, Sean MacDermott, and Tom Clarke.  The latter two were to be the primary instigators of the Easter Rising in 1916.  Following the establishment of the Ulster Volunteers in 1912, whose purpose was to resist Home Rule, by force if necessary, the IRB were behind the initiative which eventually led to the inauguration of the Irish Volunteers in November 1913.  Though the Volunteers’ stated purpose was not the establishment of a republic, the IRB intended to use the organisation to do just that, recruiting high-ranking members into the IRB, notably Joseph Plunkett, Thomas MacDonagh, and Patrick Pearse, who was co-opted to the Supreme Council in 1915. These men, together with Clarke, MacDermott, Eamonn Ceannt and eventually James Connolly of the Irish Citizen Army, constituted the Military Committee, the sole planners of the Rising. War of Independence, Civil War and dissolution.

Following the Rising some republicans—notably Éamon de Valera and Cathal Brugha—left the organization, which they viewed as no longer necessary, since the Irish Volunteers now performed its function.  The IRB, during the 1919–21 War of Independence, was under the control of Michael Collins, who was secretary, and subsequently president, of the Supreme Council.  Volunteers such as Séamus Robinson said afterwards that the IRB by then was “moribund where not already dead”, but there is evidence that it was an important force during the war.  When the Anglo-Irish Treaty was signed on 6 December 1921, it was debated by the Supreme Council, which voted to accept it by eleven votes to four. Those on the Supreme Council who opposed the Treaty included former leader Harry Boland, Austin Stack and Liam Lynch.  Anti-Treaty republicans like Ernie O’Malley, who fought during the Civil War against the Treaty, saw the IRB as being used to undermine the Irish Republic. 

The IRB became quiescent during the Civil War, which ended in May 1923, but it emerged again later that year as a faction within the National Army that supported Minister for Defence Richard Mulcahy against the “Old IRA”, which fought against the recruitment of ex-British Army personnel and the demobilization of old IRA men.  This came to a head with the Army Mutiny of 1924, in the wake of which Mulcahy resigned and other IRB members of the army were dismissed by acting President of the Executive Council Kevin O’Higgins.  The IRB subsequently dissolved itself, although it is not known whether a formal decision was taken, or it simply ceased to function.  Presidents (1858–1922)  What follows is a list of known IRB presidents.
