Provisional Irish Republican Army

Origins , issued during the 1916 Easter Rising against British rule in Ireland The original IRA was formed in 1913 as the Irish Volunteers, at a time when all of Ireland was part of the United Kingdom. The Volunteers took part in the Easter Rising against British rule in 1916, and the War of Independence that followed the Declaration of Independence by the revolutionary parliament Dáil Éireann in 1919, during which they came to be known as the IRA. The Treaty caused a split in the IRA, and the pro-Treaty IRA were absorbed into the National Army, which defeated the anti-Treaty IRA in the Civil War. Subsequently, while denying the legitimacy of the Free State, the surviving elements of the anti-Treaty IRA focused on overthrowing the Northern Ireland state and the achievement of a united Ireland, carrying out a bombing campaign in England in 1939 and 1940, a campaign in Northern Ireland in the 1940s, and the Border campaign of 1956–1962. Following the failure of the Border campaign, internal debate took place regarding the future of the IRA. Chief-of-staff Cathal Goulding wanted the IRA to adopt a socialist agenda and become involved in politics, while traditional republicans such as Seán Mac Stíofáin wanted to increase recruitment and rebuild the IRA. Following partition, Northern Ireland became a de facto one-party state governed by the Ulster Unionist Party in the Parliament of Northern Ireland, in which Catholics were viewed as second-class citizens. Protestants were given preference in jobs and housing, and local government constituencies were gerrymandered in places such as Derry. Policing was carried out by the armed Royal Ulster Constabulary (RUC) and the B-Specials, both of which were almost exclusively Protestant. In the mid-1960s tension between the Catholic and Protestant communities was increasing. Feeling under threat, Protestants formed the Ulster Volunteer Force (UVF), a paramilitary group which killed three people in May 1966, two of them Catholic men. Civil rights marches by NICRA and a similar organisation, People's Democracy, protesting against discrimination were met by counter-protests and violent clashes with loyalists, including the Ulster Protestant Volunteers, a paramilitary group led by Ian Paisley. Marches marking the Ulster Protestant celebration The Twelfth in July 1969 led to riots and violent clashes in Belfast, Derry and elsewhere. The following month a three-day riot began in the Catholic Bogside area of Derry, following a march by the Protestant Apprentice Boys of Derry. The Battle of the Bogside caused Catholics in Belfast to riot in solidarity with the Bogsiders and to try to prevent RUC reinforcements being sent to Derry, sparking retaliation by Protestant mobs. The subsequent arson attacks, damage to property and intimidation forced 1,505 Catholic families and 315 Protestant families to leave their homes in Belfast in the Northern Ireland riots of August 1969. The riots resulted in 275 buildings being destroyed or requiring major repairs, 83.5% of them occupied by Catholics. The IRA had been poorly armed and failed to properly defend Catholic areas from Protestant attacks, which had been considered one of its roles since the 1920s. Veteran republicans were critical of Goulding and the IRA's Dublin leadership which, for political reasons, had refused to prepare for aggressive action in advance of the violence. On 24 August a group including Joe Cahill, Seamus Twomey, Dáithí Ó Conaill, Billy McKee, and Jimmy Steele came together in Belfast and decided to remove the pro-Goulding Belfast leadership of Billy McMillen and Jim Sullivan and return to traditional militant republicanism. On 22 September Twomey, McKee, and Steele were among sixteen armed IRA men who confronted the Belfast leadership over the failure to adequately defend Catholic areas. The IRA split into "Provisional" and "Official" factions in December 1969, after an IRA convention was held in Boyle, County Roscommon, Republic of Ireland. The two main issues at the convention were a resolution to enter into a "National Liberation Front" with radical left-wing groups, and a resolution to end abstentionism, which would allow participation in the British, Irish, and Northern Ireland parliaments. The traditionalists argued strongly against the ending of abstentionism, and the official minutes report the resolution passed by twenty-seven votes to twelve. Shortly after, the traditionalists held a convention which elected a "Provisional" Army Council, composed of Mac Stíofáin, Ruairí Ó Brádaigh, Paddy Mulcahy, Sean Tracey, Leo Martin, Ó Conaill, and Cahill. Nine out of thirteen IRA units in Belfast sided with the "Provisional" Army Council in December 1969, roughly 120 activists and 500 supporters. The Provisional IRA issued their first public statement on 28 December 1969, Despite the declared support of that faction of Sinn Féin, the early Provisional IRA avoided political activity, instead relying on physical force republicanism. £100,000 was donated by the Fianna Fáil-led Irish government in 1969 to the Central Citizens Defence Committee in Catholic areas, some of which ended up in the hands of the IRA. This resulted in the 1970 Arms Crisis where criminal charges were pursued against two former government ministers and others including John Kelly, an IRA volunteer from Belfast. The Provisional IRA maintained the principles of the pre-1969 IRA, considering both British rule in Northern Ireland and the government of the Republic of Ireland to be illegitimate, and the Army Council to be the provisional government of the all-island Irish Republic. This belief was based on a series of perceived political inheritances which constructed a legal continuity from the Second Dáil of 1921–1922. The IRA recruited many young nationalists from Northern Ireland who had not been involved in the IRA before, but had been radicalised by the violence that broke out in 1969. These people became known as "sixty niners", having joined after 1969. Initial phase was part of an IRA delegation which took part in peace talks with British politician William Whitelaw, the Secretary of State for Northern Ireland, in July 1972. The Official IRA was opposed to such a campaign because it felt it would lead to sectarian conflict, which would defeat their strategy of uniting the workers from both sides of the sectarian divide. The Provisional IRA's strategy was to use force to cause the collapse of the Northern Ireland government and to inflict such heavy casualties on the British Army that the British government would be forced by public opinion to withdraw from Ireland. Mac Stíofáin decided they would "escalate, escalate and escalate", in what the British Army would later describe as a "classic insurgency". In October 1970 the IRA began a bombing campaign against economic targets; by the end of the year there had been 153 explosions. The following year it was responsible for the vast majority of the 1,000 explosions that occurred in Northern Ireland. The strategic aim behind the bombings was to target businesses and commercial premises to deter investment and force the British government to pay compensation, increasing the financial cost of keeping Northern Ireland within the United Kingdom. Loyalist paramilitaries tended to target Catholics with no connection to the republican movement, seeking to undermine support for the IRA. As a result of escalating violence, internment without trial was introduced by the Northern Ireland government on 9 August 1971, with 342 suspects arrested in the first twenty-four hours. Despite loyalist violence also increasing, all of those arrested were republicans, including political activists not associated with the IRA and student civil rights leaders. The one-sided nature of internment united all Catholics in opposition to the government, and riots broke out in protest across Northern Ireland. Twenty-two people were killed in the next three days, including six civilians killed by the British Army as part of the Ballymurphy massacre on 9 August, and in Belfast 7,000 Catholics and 2,000 Protestants were forced from their homes by the rioting. Due to the deteriorating security situation in Northern Ireland the British government suspended the Northern Ireland parliament and imposed direct rule in March 1972. The suspension of the Northern Ireland parliament was a key objective of the IRA, in order to directly involve the British government in Northern Ireland, as the IRA wanted the conflict to be seen as one between Ireland and Britain. In May 1972 the Official IRA called a ceasefire, leaving the Provisional IRA as the sole active republican paramilitary organisation. New recruits saw the Official IRA as existing for the purpose of defence in contrast to the Provisional IRA as existing for the purpose of attack, increased recruitment and defections from the Official IRA to the Provisional IRA led to the latter becoming the dominant organisation. On 22 June the IRA announced that a ceasefire would begin at midnight on 26 June, in anticipation of talks with the British government. Two days later Ó Brádaigh and Ó Conaill held a press conference in Dublin to announce the Éire Nua (New Ireland) policy, which advocated an all-Ireland federal republic, with devolved governments and parliaments for each of the four historic provinces of Ireland. This was designed to deal with the fears of unionists over a united Ireland, an Ulster parliament with a narrow Protestant majority would provide them with protection for their interests. The British government held secret talks with the republican leadership on 7 July, with Mac Stíofáin, Ó Conaill, Ivor Bell, Twomey, Gerry Adams, and Martin McGuinness flying to England to meet a British delegation led by William Whitelaw. Mac Stíofáin made demands including British withdrawal, removal of the British Army from sensitive areas, and a release of republican prisoners and an amnesty for fugitives. In late 1972 and early 1973 the IRA's leadership was being depleted by arrests on both sides of the Irish border, with Mac Stíofáin, Ó Brádaigh and McGuinness all imprisoned for IRA membership. Due to the crisis the IRA bombed London in March 1973, as the Army Council believed bombs in England would have a greater impact on British public opinion. This was followed by an intense period of IRA activity in England that left forty-five people dead by the end of 1974, including twenty-one civilians killed in the Birmingham pub bombings. A series of meetings took place between the IRA's leadership and British government representatives throughout the year, with the IRA being led to believe this was the start of a process of British withdrawal. Occasional IRA violence occurred during the ceasefire, with bombs in Belfast, Derry, and South Armagh. The IRA was also involved in tit for tat sectarian killings of Protestant civilians, in retaliation for sectarian killings by loyalist paramilitaries. By July the Army Council was concerned at the progress of the talks, concluding there was no prospect of a lasting peace without a public declaration by the British government of their intent to withdraw from Ireland. In August there was a gradual return to the armed campaign, and the truce effectively ended on 22 September when the IRA set off 22 bombs across Northern Ireland. The old guard leadership of Ó Brádaigh, Ó Conaill, and McKee were criticised by a younger generation of activists following the ceasefire, and their influence in the IRA slowly declined. The younger generation viewed the ceasefire as being disastrous for the IRA, causing the organisation irreparable damage and taking it close to being defeated. Following the end of the ceasefire, the British government introduced a new three-part strategy to deal with the Troubles; the parts became known as Ulsterisation, normalisation, and criminalisation. Ulsterisation involved increasing the role of the locally recruited RUC and Ulster Defence Regiment (UDR), a part-time element of the British Army, in order to try to contain the conflict inside Northern Ireland and reduce the number of British soldiers recruited from outside of Northern Ireland being killed. Normalisation involved the ending of internment without trial and Special Category Status, the latter had been introduced in 1972 following a hunger strike led by McKee. Criminalisation was designed to alter public perception of the Troubles, from an insurgency requiring a military solution to a criminal problem requiring a law enforcement solution. As result of the withdrawal of Special Category Status, in September 1976 IRA prisoner Kieran Nugent began the blanket protest in the Maze Prison, when hundreds of prisoners refused to wear prison uniforms. In 1977 the IRA evolved a new strategy which it called the "Long War", which would remain their strategy for the rest of the Troubles. This strategy accepted that their campaign would last many years before being successful, and included increased emphasis on political activity through Sinn Féin. A republican document of the early 1980s states "Both Sinn Féin and the IRA play different but converging roles in the war of national liberation. The Irish Republican Army wages an armed campaign... Sinn Féin maintains the propaganda war and is the public and political voice of the movement". The 1977 edition of the Green Book, an induction and training manual used by the IRA, describes the strategy of the "Long War" in these terms: • A war of attrition against enemy personnel [British Army] which is aimed at causing as many casualties and deaths as possible so as to create a demand from their [the British] people at home for their withdrawal. • A bombing campaign aimed at making the enemy's financial interests in our country unprofitable while at the same time curbing long-term investment in our country. • To make the Six Counties... ungovernable except by colonial military rule. • To sustain the war and gain support for its ends by National and International propaganda and publicity campaigns. • By defending the war of liberation by punishing criminals, collaborators and informers. The "Long War" saw the IRA's tactics move away from the large bombing campaigns of the early 1970s, in favour of more attacks on members of the security forces. The IRA's new multi-faceted strategy saw them begin to use armed propaganda, using the publicity gained from attacks such as the assassination of Lord Mountbatten and the Warrenpoint ambush to focus attention on the nationalist community's rejection of British rule. The hunger strike leader Bobby Sands and Anti H-Block activist Owen Carron were successively elected to the British House of Commons, and two other protesting prisoners were elected to Dáil Éireann. The electoral successes led to the IRA's armed campaign being pursued in parallel with increased electoral participation by Sinn Féin. This strategy was known as the "Armalite and ballot box strategy", named after Danny Morrison's speech at the 1981 Sinn Féin ard fheis: Who here really believes that we can win the war through the ballot box? But will anyone here object if with a ballot paper in this hand and an Armalite in this hand we take power in Ireland? Attacks on high-profile political and military targets remained a priority for the IRA. The Chelsea Barracks bombing in London in October 1981 killed two civilians and injured twenty-three soldiers; a week later the IRA struck again in London with an assassination attempt on Lieutenant General Steuart Pringle, the Commandant General Royal Marines. In October 1984, it carried out the Brighton hotel bombing, an assassination attempt on British prime minister Margaret Thatcher, whom it blamed for the deaths of the ten hunger strikers. The bombing killed five members of the Conservative Party attending a party conference including MP Anthony Berry, with Thatcher narrowly escaping death. A planned escalation of the England bombing campaign in 1985 was prevented when six IRA volunteers, including Martina Anderson and the Brighton bomber Patrick Magee, were arrested in Glasgow. Plans for a major escalation of the campaign in the late 1980s were cancelled after a ship carrying 150 tonnes of weapons donated by Libya was seized off the coast of France. The plans, modelled on the Tet Offensive during the Vietnam War, relied on the element of surprise, which was lost when the ship's captain informed French authorities of four earlier shipments of weapons, which allowed the British Army to deploy appropriate countermeasures. In 1987 the IRA began attacking British military targets in mainland Europe, beginning with the Rheindahlen bombing, which was followed by approximately twenty other gun and bomb attacks aimed at British Armed Forces personnel and bases between 1988 and 1990. Peace process By the late 1980s, the Troubles were at a military and political stalemate, with the IRA able to prevent the British government imposing a settlement but unable to force their objective of Irish reunification. Sinn Féin president Adams was in contact with Social Democratic and Labour Party (SDLP) leader John Hume and a delegation representing the Irish government, in order to find political alternatives to the IRA's campaign. As a result of the republican leadership appearing interested in peace, British policy shifted when Peter Brooke, the Secretary of State for Northern Ireland, began to engage with them hoping for a political settlement. Backchannel diplomacy between the IRA and British government began in October 1990, with Sinn Féin being given an advance copy of a planned speech by Brooke. The speech was given in London the following month, with Brooke stating that the British government would not give in to violence but offering significant political change if violence stopped, ending his statement by saying: The British government has no selfish, strategic or economic interest in Northern Ireland: Our role is to help, enable and encourage ... Partition is an acknowledgement of reality, not an assertion of national self-interest. . The IRA's South Armagh Brigade killed seven members of the security forces in single-shot sniper attacks in 1993. The IRA responded to Brooke's speech by declaring a three-day ceasefire over Christmas, the first in fifteen years. Afterwards the IRA intensified the bombing campaign in England, planting 36 bombs in 1991 and 57 in 1992, up from 15 in 1990. The Baltic Exchange bombing in April 1992 killed three people and caused an estimated £800 million worth of damage, £200 million more than the total damage caused by the Troubles in Northern Ireland up to that point. In December 1992 Patrick Mayhew, who had succeeded Brooke as Secretary of State for Northern Ireland, gave a speech directed at the IRA in Coleraine, stating that while Irish reunification could be achieved by negotiation, the British government would not give in to violence. The secret talks between the British government and the IRA via intermediaries continued, with the British government arguing the IRA would be more likely to achieve its objective through politics than continued violence. In December 1993 a press conference was held at London's Downing Street by British prime minister John Major and the Irish Taoiseach Albert Reynolds. They delivered the Downing Street Declaration which conceded the right of Irish people to self-determination, but with separate referendums in Northern Ireland and the Republic of Ireland. In January 1994 The Army Council voted to reject the declaration, while Sinn Féin asked the British government to clarify certain aspects of the declaration. The British government replied saying the declaration spoke for itself, and refused to meet with Sinn Féin unless the IRA called a ceasefire. On 31 August 1994, the IRA announced a "complete cessation of military operations" on the understanding that Sinn Féin would be included in political talks for a settlement. A new strategy known as "TUAS" was revealed to the IRA's rank-and-file following the ceasefire, described as either "Tactical Use of Armed Struggle" to the Irish republican movement or "Totally Unarmed Strategy" to the broader Irish nationalist movement. The strategy involved a coalition including Sinn Féin, the SDLP and the Irish government acting in concert to apply leverage to the British government, with the IRA's armed campaign starting and stopping as necessary, and an option to call off the ceasefire if negotiations failed. The IRA regarded themselves as being undefeated and decommissioning as an act of surrender, and stated decommissioning had never been mentioned prior to the ceasefire being declared. , which killed two people and ended the IRA's seventeen-month ceasefire On 9 February 1996 a statement from the Army Council was delivered to the Irish national broadcaster Raidió Teilifís Éireann announcing the end of the ceasefire, and just over 90 minutes later the Docklands bombing killed two people and caused an estimated £100–150 million damage to some of London's more expensive commercial property. Three weeks later the British and Irish governments issued a joint statement announcing multi-party talks would begin on 10 June, with Sinn Féin excluded unless the IRA called a new ceasefire. The IRA's campaign continued with the Manchester bombing on 15 June, which injured over 200 people and caused an estimated £400 million of damage to the city centre. Attacks were mostly in England apart from the Osnabrück mortar attack on a British Army base in Germany. The IRA's first attack in Northern Ireland since the end of the ceasefire was not until October 1996, when the Thiepval barracks bombing killed a British soldier. In February 1997 an IRA sniper team killed Lance Bombardier Stephen Restorick, the last British soldier to be killed by the IRA. Following the May 1997 UK general election Major was replaced as prime minister by Tony Blair of the Labour Party. The new Secretary of State for Northern Ireland, Mo Mowlam, had announced prior to the election she would be willing to include Sinn Féin in multi-party talks without prior decommissioning of weapons within two months of an IRA ceasefire. One aim of the agreement was that all paramilitary groups in Northern Ireland fully disarm by May 2000. The IRA began decommissioning in a process that was monitored by Canadian General John de Chastelain's Independent International Commission on Decommissioning (IICD), with some weapons being decommissioned on 23 October 2001 and 8 April 2002. The October 2001 decommissioning was the first time an Irish republican paramilitary organisation had voluntarily disposed of its arms. This was partly triggered by Stormontgate—allegations that republican spies were operating within the Parliament Buildings and the Police Service of Northern Ireland (PSNI)—and the IRA temporarily broke off contact with de Chastelain. However, further decommissioning took place on 21 October 2003. In the aftermath of the December 2004 Northern Bank robbery, the Minister for Justice, Equality and Law Reform Michael McDowell stated there could be no place in government in either Northern Ireland or the Republic of Ireland for a party that supported or threatened the use of violence, possessed explosives or firearms, and was involved in criminality. At the beginning of February 2005, the IRA declared that it was withdrawing a decommissioning offer from late 2004. declared an end to the armed campaign, affirming that it would work to achieve its aims solely through peaceful political means and ordering volunteers to end all paramilitary activity. The IRA also stated it would complete the process of disarmament as quickly as possible. On 26 September 2005, the IICD announced that "the totality of the IRA's arsenal" had been decommissioned. Jane's Information Group estimated that the IRA weaponry decommissioned in September 2005 included: . Over 50 of these, from a batch of 100 stolen from the Norwegian Army, ended up with the IRA. , first obtained by the IRA from Libya in 1972 • 1,000 rifles • 2 tonnes of the plastic explosive Semtex • 20–30 heavy machine guns • 7 surface-to-air missiles • 7 flamethrowers • 1,200 detonators • 11 rocket-propelled grenade launchers • 90 handguns • 100+ hand grenades Having compared the weapons decommissioned with the British and Irish security forces' estimates of the IRA's arsenal, and because of the IRA's full involvement in the process of decommissioning the weapons, the IICD concluded that all IRA weaponry had been decommissioned. The Secretary of State for Northern Ireland, Peter Hain, said he accepted the conclusion of the IICD. Since then, there have been occasional claims in the media that the IRA had not decommissioned all of its weaponry. In response to such claims, the Independent Monitoring Commission (IMC) stated in its 10th report that the IRA had decommissioned all weaponry under its control. In August 2015, George Hamilton, the PSNI chief constable, stated that the IRA no longer exists as a paramilitary organisation. He added that some of its structure remains, but that the group is committed to following a peaceful political path and is not engaged in criminal activity nor directing violence. The Chief Constable stated there was no evidence that the killing of McGuigan was sanctioned by the IRA leadership. But, it added, "the leaderships of the main paramilitary groups [including the IRA's] are committed to peaceful means to achieve their political objectives." == Weaponry and operations ==

, obtained by the IRA from the United States in the early 1970s, was a symbol of its armed campaign In the early days of the Troubles the IRA was poorly armed: in Derry in early 1972 the IRA's weaponry consisted of six M1 carbines, two Thompson submachine guns, one or two M1 Garand rifles, and a variety of handguns. As a result of black market arms deals and donations from sympathisers, the IRA obtained a large array of weapons such as surface-to-air missiles; M60 machine guns; ArmaLite AR-18, FN FAL, AKM and M16 rifles; DShK heavy machine guns; LPO-50 flamethrowers; and Barrett M90 sniper rifles. The IRA also used a variety of bombs during its armed campaign, such as car and truck bombs, time bombs, and booby traps, using explosives including ANFO and gelignite donated by IRA supporters in the Republic of Ireland and the plastic explosive Semtex donated by the Libyan government. The IRA's engineering department also manufactured a series of improvised mortars in the Republic of Ireland, which by the 1990s were built to a standard comparable to military models. The IRA's development of mortar tactics was a response to the heavy fortifications on RUC and British Army bases; as IRA mortars generally fired indirectly they were able to bypass some perimeter security measures. The mortars used a variety of different firing mechanisms including delay timers, this combined with the disposable nature of the weapons allowed IRA volunteers to reduce the risk of being arrested at the scene. The IRA was mainly active in Northern Ireland, although it also attacked targets in England and mainland Europe, and limited activity also took place in the Republic of Ireland. The IRA's offensive campaign mainly targeted the British Army (including the UDR) and the RUC, with British soldiers being the IRA's preferred target. Other targets included British government officials, politicians, establishment and judicial figures, and senior British Army and police officers. The bombing campaign principally targeted political, economic and military targets, and was described by counter-terrorism expert Andy Oppenheimer as "the biggest terrorist bombing campaign in history". Economic targets included shops, restaurants, hotels, railway stations and other public buildings. Civilian deaths were counter-productive to the IRA, as they provided the British with propaganda coups and affected recruitment and funding. Despite this IRA bombs continued to kill civilians, generally due to IRA mistakes and incompetence or errors in communication. These included the Donegall Street bombing which killed seven people including four civilians, and Bloody Friday, when nine people, five of them civilians, were killed when twenty-two bombs were planted in a one-mile radius of Belfast city centre. and the Shankill Road bombing which killed ten people including eight civilians. == Casualties ==

The IRA was responsible for more deaths than any other organisation during the Troubles. Two detailed studies of deaths in the Troubles, the Conflict Archive on the Internet (CAIN), and the book Lost Lives, differ slightly on the numbers killed by the IRA and the total number of conflict deaths. Of these, 1,009 (about 59%) were members or former members of the British security forces, while 508 (about 29%) were civilians. According to Lost Lives, the IRA was responsible for 1,781 deaths, about 47% of the total conflict deaths. Of these, 944 (about 53%) were members of the British security forces, while 644 (about 36%) were civilians (including 61 former members of the security forces). Overall, the IRA was responsible for 87–90% of the total British security force deaths, and 27–30% of the total civilian deaths. Between 275 and 300 IRA members were killed during the Troubles, with the IRA's biggest loss of life in a single incident being the Loughgall ambush in 1987, when eight volunteers attempting to bomb a police station were killed by the British Army's Special Air Service. == Structure ==

All levels of the organisation were entitled to send delegates to General Army Conventions. October 1986, After the 1997 ceasefire they were held more frequently, and are known to have been held in October 1997, May 1998, December 1998 or early 1999, and June 2002. The convention elected a 12-member Executive, which selected seven members, usually from within the Executive, to form the Army Council. Any vacancies on the Executive would then be filled by substitutes previously elected by the convention. The chief-of-staff would be assisted by an adjutant general as well as a General Headquarters (GHQ) staff, which consisted of a quartermaster general, and directors of finance, engineering, training, intelligence, publicity, operations, and security. In 1977, parallel to the introduction of cell structures at the local level, command of the "war-zone" was given to the Northern Command, which facilitated coordinated attacks across Northern Ireland and rapid alterations in tactics. Another department attached to GHQ but separate from all other IRA structures was the England department, responsible for the bombing campaign in England. The IRA referred to its ordinary members as volunteers (or óglaigh in Irish), to reflect the IRA being an irregular army which people were not forced to join and could leave at any time. Until the late 1970s, IRA volunteers were organised in units based on conventional military structures. Volunteers living in one area formed a company as part of a battalion, which could be part of a brigade, such as the Belfast Brigade, Derry Brigade, South Armagh Brigade, and East Tyrone Brigade. In late 1973 the Belfast Brigade restructured, introducing clandestine cells named active service units, consisting of between four and ten members. Similar changes were made elsewhere in the IRA by 1977, moving away from the larger conventional military organisational principle owing to its security vulnerability. The old structures were used for support activities such as policing nationalist areas, intelligence-gathering, and hiding weapons, while the bulk of attacks were carried out by active service units, using weapons controlled by the brigade's quartermaster. The exception to this reorganisation was the South Armagh Brigade, which retained its traditional hierarchy and battalion structure. Only a handful of volunteers from the South Armagh Brigade were convicted of serious offences, and it had fewer arrests than any other area, meaning that the security forces struggled to recruit informers. == Political ideology ==

, who left the IRA in 1986 and formed the League of Communist Republicans The IRA's goal was an all-Ireland democratic socialist republic. Richard English, a professor at Queen's University Belfast, writes that while the IRA's adherence to socialist goals has varied according to time and place, radical ideas, specifically socialist ones, were a key part of IRA thinking. This was in contrast to the Official IRA and the Irish National Liberation Army, both of which adopted clearly defined Marxist positions. Similarly, the Northern Ireland left-wing politician Eamonn McCann has remarked that the Provisional IRA was considered a non-socialist IRA compared to the Official IRA. During the 1980s, the IRA's commitment to socialism became more solidified as IRA prisoners began to engage with works of political and Marxist theory by authors such as Frantz Fanon, Che Guevara, Antonio Gramsci, Ho-Chi Minh, and General Giap. Members felt that an Irish version of the Tet Offensive could possibly be the key to victory against the British, pending on the arrival of weapons secured from Libya. == Categorisation ==

The IRA is a proscribed organisation in the United Kingdom under the Terrorism Act 2000, and an unlawful organisation in the Republic of Ireland under the Offences Against the State Acts, where IRA volunteers are tried in the non-jury Special Criminal Court. A similar system was introduced in Northern Ireland by the Northern Ireland (Emergency Provisions) Act 1973, with a Diplock court consisting of a single judge and no jury. The IRA rejected the authority of the courts in Northern Ireland and the Republic of Ireland, and its standing orders did not allow volunteers on trial in a criminal court to enter a plea or recognise the authority of the court; doing so could lead to expulsion from the IRA. These orders were relaxed in 1976 due to sentences in the Republic of Ireland for IRA membership being increased from two years to seven years imprisonment. IRA prisoners in the UK and the Republic of Ireland were granted conditional early release as part of the Good Friday Agreement. IRA members were often refused travel visas to enter the United States, due to previous criminal convictions or because the Immigration and Nationality Act bars the entry of people who are members of an organisation which advocates the overthrow of a government by force. American TV news broadcasts used the terms "activists", "guerrillas", and "terrorists" to describe IRA members, while British TV news broadcasts commonly used the term "terrorists", particularly the BBC as part of its editorial guidelines published in 1989. Republicans reject the label of terrorism, instead describing the IRA's activity as war, military activity, armed struggle or armed resistance. The IRA prefer the terms freedom fighter, soldier, activist, or volunteer for its members. The IRA has also been described as a "private army". The IRA saw the Irish War of Independence as a guerrilla war which accomplished some of its aims, with some remaining "unfinished business". An internal British Army document written by General Sir Mike Jackson and two other senior officers was released in 2007 under the Freedom of Information Act. It examined the British Army's 37 years of deployment in Northern Ireland, and described the IRA as "a professional, dedicated, highly skilled and resilient force", while loyalist paramilitaries and other republican groups were described as "little more than a collection of gangsters". == Strength and support ==

Numerical strength It is unclear how many people joined the IRA during the Troubles, as it did not keep detailed records of personnel. McGuinness, who held a variety of leadership positions, estimated a total membership of 10,000 over the course of the Troubles. journalist Ed Moloney states by the end of the year the IRA in Belfast had over 1,200 volunteers. the British Army estimated the IRA had 500 full-time volunteers. A 1978 British Army report by Brigadier James Glover stated that the restructured IRA did not require the same number of volunteers as the early 1970s, and that a small number of volunteers could "maintain a disproportionate level of violence". Journalist Brendan O'Brien states by the late 1980s the IRA had roughly 300 active volunteers and 450 more in support roles, while historian Richard English states in 1988 the IRA was believed to have no more than thirty experienced gunmen and bombers, with a further twenty volunteers with less experience and 500 more in support roles. Support from other countries and organisations assault rifles were donated by Muammar Gaddafi in the 1980s and another five in the mid-1980s. The final shipment in 1987 was intercepted by French authorities, He also gave $12 million in cash to the IRA. Irish Americans (both Irish immigrants and natives of Irish descent) also donated weapons and money. The key IRA transatlantic gunrunning network was run by Irish immigrant and IRA veteran George Harrison, who estimated to have smuggled 2,000–2,500 weapons and approximately 1 million rounds of ammunition to Ireland. However, the Federal Bureau of Investigation arrested Harrison for IRA arms smuggling in June 1981, thereby blocking the IRA's arms supply from America. This forced the IRA to focus on importing weaponry from its already-established networks in Europe and the Middle East. In addition, Irish American support for the Republican cause began to weaken in the mid-1970s and gradually diminished in the 1980s due to bad publicity surrounding IRA atrocities and NORAID. By 1998, only $3.6 million were raised in America for the Irish Republican cause, in which many historians and scholars agreed such an amount was too small to make an actual difference in the conflict. More than A$20,000 were sent per year to the Provisionals from supporters in Australia by the 1990s. Canadian supporters did not just fundraise and import weapons, but also smuggled IRA and Sinn Féin members into the United States, which, unlike Canada, enacted a visa ban on such members on the basis of advocating violence since the early 1970s. Gearóid Ó Faoleán wrote that "[i]n 1972, inclement weather forced a light aeroplane to reroute to Shannon Airport from Farranfore in County Kerry, where IRA volunteers had been awaiting its arrival. The plane, piloted by a Canadian [IRA supporter], had flown from Libya with at least one cargo of arms that included RPG-7 rocket launchers" where IRA smuggled these weapons into safe houses for its armed campaign. In 1974, seven Canadian residents (six who were originally from Belfast) were arrested by the Royal Canadian Mounted Police for smuggling weapons to the IRA after "raids in St. Catharines, Tavistock and Toronto and at the U.S. border at Windsor". Philip Kent, one of those arrested, was discovered in his car for having "fifteen FN rifles and a .50 calibre machine gun". Former MI5 agent Willie Carlin said that one of the main reasons why the IRA Army Council did not attack Scotland during the conflict was because doing so would reduce support from Scots and have a negative impact on its fundraising and other activities there. Carlin explained that "[t]here were politicians in Scotland, a lot of whom were very sympathetic to the nationalist cause, and even the Sinn Fein cause". He also noted that while much of the money was donated by supporters in Glasgow, funds also came from all over the country, from "farmers up there who had family and relatives in Ireland". The IRA had links with the Basque separatist group ETA. In 1973 the IRA was accused by the Spanish police of providing explosives for the assassination of Spanish prime minister Luis Carrero Blanco in Madrid, and the following year an ETA spokesman told German magazine Der Spiegel they had "very good relations" with the IRA. The IRA received support from the Palestine Liberation Organization (PLO) in the 1970s, with volunteers attending training camps in the Middle East. The shipment included twenty-nine AK-47 assault rifles, twenty-nine French submachine guns, seven RPG-7 rocket launchers and sixty rocket-propelled grenades, two Bren light machine guns, mortars, grenades and ammunition. In May 1996, the Federal Security Service, Russia's internal security service, accused Estonia of arms smuggling, and claimed that the IRA had bought weapons from arms dealers linked to Estonia's volunteer defence force, Kaitseliit. In 2001, three Irishmen, known as the Colombia Three, were arrested and accused of training Colombian guerrillas, the Revolutionary Armed Forces of Colombia (FARC). The Irish Minister for Justice, Equality and Law Reform stated the IRA was to be paid up to $35 million to train FARC in bomb-making techniques, including shaped charges, propane bombs, landmines and the construction of mortars. In 2005 a commander in the National Army of Colombia stated IRA techniques were being used all over Colombia by FARC, and British military experts confirmed bombs used by FARC had previously been used by the IRA. Since the Troubles began, the IRA was involved in criminal activities such as robberies, counterfeiting, protection rackets, kidnapping for ransom, fuel laundering and cigarette smuggling in order to fund its armed campaign. The IRA also raised funds by running legitimate businesses such as taxi firms, nightclubs, offices, and nursing homes. IRA supporters argue that as it was a clandestine organisation it was forced to use extra legal methods of fundraising, which were justified in order to achieve a political goal. The PSNI, the IMC, and the British and Irish governments all accused the IRA of involvement in the biggest bank raid in British history—the 2004 Northern Bank robbery—when £26.5 million was stolen, which the IRA denied. In April 1987, RUC chief constable John Hermon told government ministers at the Anglo-Irish Intergovernmental Conference that "[i]t costs the IRA £2–£3 million per year to maintain its activity. That amount is no problem to them and they have no shortage of money to purchase weapons." The Northern Ireland Affairs Select Committee in its 26 June 2002 report stated that "the importance of overseas donations has been exaggerated and donations from the USA have formed only a small portion of IRA income." It identified extortion, fuel laundering, rum-running, tobacco smuggling, armed robbery, and counterfeiting in Ireland and Britain as the primary sources of funding for both Republican and Loyalist militants throughout and after the Troubles, while "the sums involved [from overseas] [were and] are comparatively small". The committee estimated that the Provisional IRA made £5–8 million a year while spending £1.5m annually to carry out its campaign. Generally, the IRA was against drug dealing and prostitution, because it would be unpopular within Catholic communities and for moral reasons. The chief of the RUC Drugs Squad, Kevin Sheehy, said the IRA tried to prevent volunteers being directly involved with drugs, and noted one occasion when an IRA member caught with a small amount of cannabis was "disowned and humiliated" in his local area. The IRA targeted drug dealers with punishment shootings and ordered them to leave Ireland, and some were killed using the covername Direct Action Against Drugs. However, there are claims the IRA "licensed" certain dealers to operate and forced them to pay protection money. Following the murder of Robert McCartney in 2005, the IRA expelled three IRA volunteers. Adams said at Sinn Féin's 2005 ard fheis "There is no place in republicanism for anyone involved in criminality", while adding "we refuse to criminalise those who break the law in pursuit of legitimate political objectives". This was echoed shortly after by an IRA statement issued at Easter, saying that criminality within the ranks would not be tolerated. In 2008, the IMC stated that the IRA was no longer involved in criminality, but that some members have engaged in criminality for their own ends, without the sanction or support of the IRA. Popular support Support for the IRA within nationalist communities and within the Republic of Ireland has fluctuated over the course of the conflict. In September 1979 the Economic and Social Research Institute conducted a wide-ranging survey of attitudes to the IRA in the Republic. Its findings showed that 20.7% broadly supported IRA activities, while 60.5% opposed them. Meanwhile, when respondents were asked whether they sympathised or rejected their motives, 44.8% of respondents expressed some level of sympathy with their motives while 33.5% broadly rejected them. A study in 1999 showed amongst Catholics in Northern Ireland, 42% of respondents expressed sympathy with republican violence while 52% said they had no sympathy. The same study found 39.7% of respondents in the Republic of Ireland sympathised with republican violence. According to a 2022 poll, 69% of Irish nationalists polled believe there was no option but "violent resistance to British rule during the Troubles". == Other activities ==

Sectarian attacks The IRA publicly condemned sectarianism and sectarian attacks, however some IRA members did carry out sectarian attacks. Of those killed by the IRA, Malcolm Sutton classifies 130 (about 7%) of them as sectarian killings of Protestants, 88 of them committed between 1974 and 1976. Unlike loyalists, the IRA denied responsibility for sectarian attacks and the members involved used cover names, such as "Republican Action Force", which was used to claim responsibility for the 1976 Kingsmill massacre where ten Protestant civilians were killed in a gun attack. They stated that their attacks on Protestants were retaliation for attacks on Catholics. Robert White, a professor at the Indiana University, states the IRA was generally not a sectarian organisation, and Rachel Kowalski from the Department of War Studies, King's College London states that the IRA acted in a way that was mostly blind to religious diversity. Protestants in the rural border areas of counties Fermanagh and Tyrone, where the number of members of the security forces killed was high, viewed the IRA's campaign as ethnic cleansing. Henry Patterson, a professor at the University of Ulster, concludes that while the IRA's campaign was unavoidably sectarian, it did not amount to ethnic cleansing. Although the IRA did not specifically target these people because of their religious affiliation, more Protestants joined the security forces so many people from that community believed the attacks were sectarian. Vigilantism , County Tyrone During the Troubles, the IRA took on the role of policing in some nationalist areas of Northern Ireland. Many nationalists did not trust the official police force—the RUC—and saw it as biased against their community. The RUC found it difficult to operate in certain nationalist neighbourhoods and only entered in armoured convoys due to the risk of attack, preventing community policing that could have occurred if officers patrolled on foot. In these neighbourhoods, many residents expected the IRA to act as a policing force, and such policing had propaganda value for the IRA. The IRA also sought to minimise contact between residents and the RUC, because residents might pass on information or be forced to become a police informer. First time offenders may have been given a warning, or for more serious offences a curfew may have been imposed. Those responsible for more serious and repeat offences could have been given a punishment beating, or banished from the community. No punishment attacks have been officially attributed to the IRA since February 2006. The vigilantism of the IRA and other paramilitary organisations has been condemned as "summary justice". In January 1971, the IRA and British Army held secret talks aimed at stopping persistent rioting in Ballymurphy. It was agreed that the IRA would be responsible for policing there, but the agreement was short-lived. The incident centres were seen by locals as "IRA police stations" and gave some legitimacy to the IRA as a policing force. In the 1980s, many IRA members were arrested after being implicated by former IRA members known as "supergrasses" such as Raymond Gilmour. There have been some high-profile allegations of senior IRA figures having been British informers. In May 2003, an American website named Freddie Scappaticci as being a British spy code-named Stakeknife. Scappaticci was said to be a high-level IRA informer working for the British Army's Force Research Unit, while he was head of the IRA's Internal Security Unit, which interrogated and killed suspected informers. Scappaticci denied being Stakeknife, and involvement in IRA activity. Donaldson, who ran Sinn Féin's operations in New York during the Northern Ireland peace process, was expelled by the party. On 4 April 2006, Donaldson was shot dead by the Real IRA splinter group at his retreat near Glenties in County Donegal. Other prominent informers include Eamon Collins, The IRA regarded informers as traitors, and a threat to the organisation and lives of its members. Suspected informers were dealt with by the IRA's Internal Security Unit, which carried out an investigation and interrogated the suspects. Following this a court martial would take place, consisting of three members of equal or higher rank than the accused, plus a member of GHQ or the Army Council acting as an observer. Any death sentence would be ratified by the Army Council, who would be informed of the verdict by the observer. The IRA usually killed informers with a single shot to the head, There was also a group of sixteen people known as the Disappeared who were secretly buried between 1972 and 1985, which included alleged informers, agents for the security forces, and people that stole IRA weapons and used them in armed robberies. In March 1999, the IRA apologised for the "prolonged anguish" caused to the families of the Disappeared, and stated it had identified the burial places of nine people, including the most high-profile victim, Jean McConville, a Catholic civilian and widowed mother-of-ten. This led to the recovery of three bodies later in 1999, although Jean McConville's body was not recovered until August 2003. == Splinter groups ==

Former IRA volunteers are involved in various dissident republican splinter groups, which are active in the low-level dissident Irish republican campaign. The oldest dissident group is the Continuity IRA, which formed in 1986 following a split in the republican movement, over the decision to allow members, if elected, to take seats in Dáil Éireann. This group was inactive for several years while acquiring weapons and finance, their first attack was in 1994 during the Provisional IRA's first ceasefire. The Real IRA was formed in November 1997 when senior Provisional IRA members, including quartermaster-general Michael McKevitt, resigned over acceptance of the Mitchell Principles. The Real IRA is best known for the 1998 Omagh bombing which killed 29 civilians, and the 2009 Massereene Barracks shooting which killed two British soldiers. In 2005/6 some Provisional IRA members defected and formed Óglaigh na hÉireann, which became active in 2009. This group also included former members of the Irish National Liberation Army and a faction that splintered from the Real IRA. The group was believed to have formed in 2008, and included former senior Provisional IRA members unhappy at Sinn Féin's direction and the peace process. This vigilante group's membership included former Provisional IRA members and members of other republican groups. == Notes and references ==
