[[Irish nationalists]] and [[Irish republicanism|republicans]], who were mostly [[Irish Catholics]], wanted Northern Ireland to leave the [[United Kingdom]] and join a [[united Ireland]].

The conflict began during a campaign by the [[Northern Ireland Civil Rights Association]] to end discrimination against the Catholic-nationalist minority by [[Government of Northern Ireland (1921–1972)|the Protestant-unionist government]] and local authorities.<ref>{{cite book |first1=Richard |last1=English |title=The State: Historical and Political Dimensions |first2=Charles |last2=Townshend |date=1998 |publisher=Routledge |page=96 |isbn=0-415-15477-4}}.</ref><ref name="dbryan">{{cite book |first=Dominic |last=Bryan |title=Orange Parades: The Politics of Ritual, Tradition and Control |publisher=Pluto Press |date=2000 |page=94 |isbn=0-7453-1413-9}}.</ref> The government attempted to suppress the protests. The police, the [[Royal Ulster Constabulary]] (RUC), were overwhelmingly Protestant and known for sectarianism and [[police brutality]]. The campaign was also violently opposed by Ulster loyalists, who believed it was a front for republican political activity. Increasing tensions led to the [[1969 Northern Ireland riots|August 1969 riots]] and the [[Operation Banner|deployment of British troops]], in what became the [[British Army]]'s longest operation.<ref>{{cite news |url=https://www.bbc.co.uk/news/uk-northern-ireland-49250284 |title=The Troubles: How 1969 violence led to Army's longest campaign |date=14 August 2019 |publisher=BBC News |archive-url=https://web.archive.org/web/20191001024019/https://www.bbc.co.uk/news/uk-northern-ireland-49250284 |archive-date=1 October 2019 |url-status=dead}}</ref> "[[Peace lines|Peace walls]]" were built in some areas to keep the two communities apart.

The main [[Outline of the Troubles|participants in the Troubles]] were republican [[paramilitaries]] such as the [[Provisional Irish Republican Army]] (IRA) and the [[Irish National Liberation Army]] (INLA); loyalist paramilitaries such as the [[Ulster Volunteer Force]] (UVF) and [[Ulster Defence Association]] (UDA); British state security forces such as the British Army and RUC; and political activists. The security forces of the Republic of Ireland played a smaller role. Republicans carried out a [[guerrilla]] campaign against British forces as well as a bombing campaign against infrastructural, commercial, and political targets. Loyalists attacked republicans/nationalists and the wider Catholic community in what they described as retaliation. At times, there were bouts of sectarian [[tit-for-tat]] violence, as well as feuds within and between paramilitary groups. The British security forces undertook policing and [[counterinsurgency]], primarily against republicans. There were incidents of collusion between British state forces and loyalist paramilitaries (see [[Stevens Inquiries]]). The Troubles also involved numerous riots, mass protests, and acts of [[civil disobedience]], and led to increased [[Segregation in Northern Ireland|segregation]] and the creation of temporary no-go areas.

The word "troubles" has been used as a synonym for violent conflict for centuries. It was used to describe the 17th-century [[Wars of the Three Kingdoms]] by all three national parliaments. For example, after the [[Restoration (1660)|Restoration]] in 1660, the English ''[[S:An act of free and general pardon, indemnity and oblivion|Act of free and general pardon, indemnity and oblivion]]'' starts with "The King's most excellent Majesty, taking into his gracious and serious consideration the long and great troubles&nbsp;..."; as does the similar act in Scotland: "The king's most excellent majesty, considering that by the late troubles diverse of his subjects&nbsp;..." (Scottish Parliament 1662); and by the [[Parliament of Ireland|Irish Parliament]] in the [[Act of Settlement 1662#The Act of 1665|Act of Explanation (1665)]] "our royal father of blessed memory had been forced, during the late troubles, to make with the Irish subjects of that our kingdom" (Irish Parliament 1665, § 2).

== Background ==

=== 1609–1791 ===

In 1609, Scottish and English settlers, known as ''planters'', were given land [[escheat]]ed from the native Irish in the [[Plantation of Ulster]].<ref>{{cite news |url=http://edition.cnn.com/2008/WORLD/europe/03/12/northern.ireland/index.html |title=Out of trouble: How diplomacy brought peace to Northern Ireland |work=CNN|date=17 March 2008 |access-date=2 November 2008 |archive-date=19 July 2008 |archive-url=https://web.archive.org/web/20080719001308/http://edition.cnn.com/2008/WORLD/europe/03/12/northern.ireland/index.html |url-status=live }}</ref> Coupled with Protestant immigration to "unplanted" areas of [[Ulster]], particularly [[Antrim, County Antrim|Antrim]] and [[County Down|Down]], this resulted in conflict between the native Catholics and the "planters", leading in turn to two bloody religious conflicts known as the [[Irish Confederate Wars]] (1641–1653) and the [[Williamite war]] (1689–1691), both of which resulted in Protestant victories.

[[Anglican]] dominance in Ireland was ensured by the passage of the [[Penal Laws (Ireland)|Penal Laws]] that curtailed the religious, legal, and political rights of anyone (including both Catholics and Protestant Dissenters, such as [[Presbyterian]]s) who did not conform to the state church, the Anglican [[Church of Ireland]]. As the Penal Laws started to be phased out in the latter part of the 18th century, there was more competition for land, as restrictions were lifted on the Irish Catholic ability to rent. With Irish Catholics allowed to buy land and enter trades from which they had formerly been banned, tensions arose resulting in the Protestant "[[Peep o'Day Boys]]"<ref name="Wright">Frank Wright. ''Ulster: Two Lands, One Soil'', 1996, p. 17.<!-- publishing info and ISBN needed --></ref> and Catholic "[[Defenders (Ireland)|Defenders]]". This created polarisation between the communities and a dramatic reduction in reformers among Protestants, many of whom had been growing more receptive to democratic reform.<ref name="Wright"/>

=== 1791–1912 ===
Following the foundation of the [[Irish republican|republican]] [[Society of the United Irishmen]] by Presbyterians, Catholics, and liberal Anglicans, and the resulting failed [[Irish Rebellion of 1798]], sectarian violence between Catholics and Protestants continued. The [[Orange Order]] (founded 1795), with its stated goal of upholding the Protestant faith and loyalty to the heirs of [[William III of England|William of Orange]], dates from this period and remains active to this day.<ref>{{cite news |url=http://news.bbc.co.uk/2/hi/uk_news/northern_ireland/1422212.stm |title=Profile: The Orange Order |publisher=BBC News |date=4 July 2001 |access-date=2 November 2008 |archive-date=29 June 2008 |archive-url=https://web.archive.org/web/20080629181232/http://news.bbc.co.uk/2/hi/uk_news/northern_ireland/1422212.stm |url-status=live }}</ref>

With the [[Acts of Union 1800]] (which came into force on 1 January 1801), a new political framework was formed with the abolition of the [[Parliament of Ireland|Irish Parliament]] and incorporation of Ireland into the [[United Kingdom of Great Britain and Ireland]]. The result was a closer tie between Anglicans and the formerly republican Presbyterians as part of a "loyal" Protestant community. Although [[Catholic emancipation]] was achieved in 1829, largely eliminating official discrimination against Roman Catholics (then around 75% of Ireland's population), Dissenters, and Jews, the [[Repeal Association]]'s campaign to repeal the 1801 Union failed.

In the late 19th century, the [[Irish Home Rule movement|Home Rule movement]] was created and served to define the divide between most nationalists (usually Catholics) who sought the restoration of an Irish Parliament, and most unionists (usually Protestants) who were afraid of being a minority under a Catholic-dominated Irish Parliament and who tended to support continuing union with Great Britain.

Unionists and Home Rule advocates were the main political factions in late 19th- and early 20th-century Ireland.<ref>{{cite book |last=English |first=Richard |title=Irish Freedom: The History of Nationalism in Ireland |publisher=Pan Books |date=2006 |pages = 200–231 |isbn=978-0-330-42759-3}}</ref>

=== 1912–1922 ===
{{Main|Partition of Ireland}}
[[File:Ulster Covenant.jpg|thumb|upright=0.7|The ''[[Ulster Covenant]]'' was issued in protest against the [[Third Home Rule Bill]] in September 1912.]]
[[File:Easter Proclamation of 1916.png|thumb|upright=0.7|The ''[[Proclamation of the Irish Republic]]'' was issued during the [[Easter Rising]] of April 1916.]]
[[File:Irish Boundary Commission final report map (1925) - religious distribution.png|thumb|Irish Boundary Commission final report map (1925) shows religious distribution of the population. The green areas signify Catholic majority areas, while the red areas signify non-Catholic majority areas.]]

By the second decade of the 20th century, Home Rule, or limited Irish self-government, was on the brink of being conceded due to the agitation of the [[Irish Parliamentary Party]].
In response to the campaign for Home Rule which started in the 1870s, unionists, mostly Protestant and largely concentrated in Ulster, had resisted both self-government and independence for Ireland, fearing for their future in an overwhelmingly Catholic country dominated by the Roman Catholic Church. In 1912, unionists led by [[Edward Carson]] signed the [[Ulster Covenant]] and pledged to resist Home Rule by force if necessary. To this end, they formed the paramilitary [[Ulster Volunteers|Ulster Volunteer Force]] (UVF).<ref name="coogan"/>

In response, nationalists led by [[Eoin MacNeill]] formed the [[Irish Volunteers]] in 1913, whose goal was to oppose the UVF and ensure enactment of the [[Third Home Rule Bill]] in the event of British or unionist refusal. The outbreak of the [[First World War]] in 1914, and [[Ireland and World War I|Ireland's involvement in the war]], temporarily averted possible civil war in Ireland and delayed the resolution of the question of Irish independence. Home Rule, although passed in the British Parliament with [[Royal Assent]], was suspended for the duration of the war.

The Irish Volunteers split, with a majority, known as the [[National Volunteers]], supporting the war effort, and some of them joining Irish regiments of the [[Kitchener's Army|New British Army]]. Many of those who stayed were radical nationalists, among them [[Irish Republican Brotherhood]] infiltrators. From these ranks came those who launched the [[Easter Rising]] in Dublin in 1916, led by [[Patrick Pearse]] and [[James Connolly]]. Two-and-a-half years after the executions of sixteen of the Rising's leaders, the separatist [[Sinn Féin]] party won the December 1918 [[1918 Irish general election|general election in Ireland]] with 47% of the vote and a majority of seats, and set up the 1919 [[First Dáil]] (Irish Parliament) in Dublin. Their victory was aided by the [[Conscription Crisis of 1918|threat of conscription for First World War service]]. The [[Irish War for Independence]] followed, leading to eventual independence in 1922 for the [[Irish Free State]], which comprised 26 of the 32 Irish counties. In [[Ulster]], particularly in the six counties which became [[Northern Ireland]], Sinn Féin fared relatively poorly in the 1918 election, and unionists won a majority.<ref name="coogan"/>

The [[Government of Ireland Act 1920]] partitioned the island of Ireland into two separate jurisdictions, [[Southern Ireland (1921–1922)|Southern Ireland]] and Northern Ireland, both devolved regions of the United Kingdom. This [[partition of Ireland]] was confirmed when the [[Parliament of Northern Ireland]] exercised its right in December 1922 under the [[Anglo-Irish Treaty]] of 1921 to opt out of the newly established Irish Free State.<ref name="Parliament">[https://publications.parliament.uk/pa/cm199394/cmhansrd/1993-12-15/Debate-1.html Parliamentary debate] {{Webarchive|url=https://web.archive.org/web/20101010094440/http://www.publications.parliament.uk/pa/cm199394/cmhansrd/1993-12-15/Debate-1.html |date=10 October 2010 }}: "The British government agree that it is for the people of the island of Ireland alone, by agreement between the two parts respectively, to exercise their right of self-determination on the basis of [[Principle of consent|consent]], freely and concurrently given, North and South, to bring about a united Ireland, if that is their wish."</ref> A part of the treaty signed in 1922 mandated that a boundary commission would sit to decide where the frontier of the northern state would be in relation to its southern neighbour. After the [[Irish Civil War]] of 1922–1923, this part of the treaty was given less priority by the new Dublin government led by [[W. T. Cosgrave]], and was quietly dropped. As counties [[County Fermanagh|Fermanagh]] and [[County Tyrone|Tyrone]] and border areas of [[County Londonderry|Londonderry]], [[County Armagh|Armagh]], and Down were mainly nationalist, the [[Irish Boundary Commission]] could reduce Northern Ireland to four counties or fewer.<ref name="coogan"/> In October 1922, the Irish Free State government established the [[North-Eastern Boundary Bureau]], a government office which by 1925 had prepared 56 boxes of files to argue its case for areas of Northern Ireland to be transferred to the Free State.<ref>{{cite book | editor-last=Crowley | editor-first=John | editor-last2=Ó Drisceoil | editor-first2=Donal | editor-last3=Murphy | editor-first3=Michael | editor-last4=Borgonovo | editor-first4=John | editor-last5=Hogan | editor-first5=Nick | title=Atlas of the Irish Revolution | publisher = NYU Press | publication-place=New York | date=2017 | isbn=978-1-4798-3428-0 | oclc=1001466881 | page=830}}</ref>

Northern Ireland remained a part of the United Kingdom, albeit under a separate system of government whereby it was given its own [[Parliament of Northern Ireland|parliament]] and [[devolved government]]. While this arrangement met the desires of unionists to remain part of the United Kingdom, nationalists largely viewed the partition of Ireland as an illegal and arbitrary division of the island against the will of the majority of its people. They argued that the Northern Ireland state was neither legitimate nor democratic, but created with a deliberately [[gerrymandered]] unionist majority. Catholics initially composed about 35% of its population.<ref name="familiesatwar">{{cite book|author=Peter Taylor|title=Families at War |publisher=BBC |date=1989 |page=[https://archive.org/details/familiesatwarvoi0000tayl/page/10 10]|isbn=978-0-563-20787-0|url=https://archive.org/details/familiesatwarvoi0000tayl/page/10}}</ref> A total of 557 people, mostly Catholics, were killed in political or sectarian violence from 1920 to 1922 in the six counties that would become Northern Ireland, both during and after the Irish War of Independence.<ref>{{cite book|last=English|first=Richard|author-link=Richard English|title=Armed Struggle: The History of the IRA|publisher=Oxford University Press|date=2003|pages=39–40|isbn=978-0-19-517753-4|url=https://books.google.com/books?id=WxJutBLDxg0C&pg=PR3|access-date=3 October 2016|archive-date=20 April 2017|archive-url=https://web.archive.org/web/20170420031341/https://books.google.com/books?id=WxJutBLDxg0C&pg=PR3|url-status=live}}</ref> The result was communal strife between Catholics and Protestants,<ref>{{cite web |title=CRESC Working Paper Series : Working Paper No. 122 |url=http://www.cresc.ac.uk/medialibrary/workingpapers/wp122.pdf |url-status=dead |archive-url=https://web.archive.org/web/20170101170441/http://www.cresc.ac.uk/medialibrary/workingpapers/wp122.pdf |archive-date=1 January 2017 |access-date=3 October 2016 |website=Cresc.ac.uk}}</ref> with some historians describing this violence, especially that in [[Belfast]], as a [[pogrom]],<ref>{{cite journal|url=https://www.academia.edu/6318325 |title=Facts and Figures of the Belfast Pogroms G.B.

[[File:James Craig, 1st Viscount Craigavon.jpg|alt=A black-and-white picture of a man with a moustache.|thumb|[[James Craig, 1st Viscount Craigavon|Sir James Craig]], 1st Prime Minister of Northern Ireland, who said, "All I boast is that we are a Protestant Parliament and Protestant State"]]
A marginalised remnant of the [[Irish Republican Army (1922–1969)|Irish Republican Army]] survived the [[Irish Civil War]]. This would come to have a major impact on Northern Ireland. Although the IRA was proscribed on both sides of the new [[Irish border]], it remained ideologically committed to overthrowing both the Northern Ireland and the Free State governments by force of arms to unify Ireland. The [[Government of Northern Ireland (1921–1972)|government of Northern Ireland]] passed the [[Civil Authorities (Special Powers) Act (Northern Ireland) 1922|Special Powers Act]] in 1922, giving sweeping powers to the government and police to intern suspects without trial and to administer [[corporal punishment]] such as [[flogging]] to re-establish or preserve law and order. The Act continued to be used against nationalists long after the violence of this period had come to an end.<ref>Laura K. Dohonue.

In 1920, in local elections held under [[proportional representation]], nationalists had won control over many local governments, including the [[County Councils]] of Fermanagh and Tyrone, and the [[Londonderry Borough Council]] governing [[Derry|Derry City]]. In response, in 1922 the new unionist government re-drew the electoral boundaries to give its supporters a disproportionate majority and abolished proportional representation in favour of [[first past the post]] voting.<ref>{{cite book |author1-last=McKittrick |author1-first=David |author2-last=McVea |author2-first=David |title=Making Sense of the Troubles: A History of the Northern Ireland |publisher=Viking |location=London |date=2012 |pages=8–10}}</ref> This resulted in control by unionists of areas such as Derry City, Fermanagh, and Tyrone, where they were actually a minority of voters.<ref>{{cite web|url=https://www.theirishstory.com/2018/12/03/revisiting-the-northern-ireland-civil-rights-movement-1968-69/|title=Revisiting the Northern Ireland Civil Rights Movement: 1968–69 – The Irish Story|access-date=17 April 2020|archive-date=7 March 2020|archive-url=https://web.archive.org/web/20200307140523/https://www.theirishstory.com/2018/12/03/revisiting-the-northern-ireland-civil-rights-movement-1968-69/|url-status=live}}</ref>

The two sides' positions became strictly defined following this period. From a unionist perspective, Northern Ireland's nationalists were inherently disloyal and determined to force unionists into a united Ireland. This threat was seen as justifying preferential treatment of unionists in housing, employment, and other fields.{{Citation needed|date=April 2023}} The prevalence of larger families and thus the potential for a more rapid population growth among Catholics was seen as a threat.{{Citation needed|date=May 2023}} Unionist governments ignored [[Edward Carson]]'s warning in 1921 that alienating Catholics would make Northern Ireland inherently unstable. After the early 1920s, there were occasional incidents of sectarian unrest in Northern Ireland. These included severe rioting in Belfast in the 1930s and 1950s, and the IRA's brief [[Northern Campaign (Irish Republican Army)|Northern Campaign]] in the 1940s and [[Border Campaign (Irish Republican Army)|Border Campaign]] between 1956 and 1962, which did not enjoy broad popular support among nationalists. After the IRA called off its campaign in 1962, Northern Ireland became relatively stable for a few years.<ref name="coogan"/>

In March and April 1966, Irish nationalists/republicans held parades throughout Ireland to mark the 50th anniversary of the [[Easter Rising]]. On 8 March, a group of Irish republicans dynamited [[Nelson's Pillar]] in Dublin.

In the mid-1960s, a non-violent [[Northern Ireland civil-rights movement (1960s)|civil rights campaign]] began in Northern Ireland.

* [[one man, one vote]] – in Northern Ireland, only householders could vote in local elections, while in the rest of the United Kingdom all adults could vote

On 24 August 1968, the civil rights movement held its first civil rights march from [[Coalisland]] to [[Dungannon]]. Many more marches were held over the following year. Loyalists (especially members of the UPV) attacked some of the marches and held counter-demonstrations in a bid to get the marches banned.<ref name="cain1968"/> Because of the lack of police reaction to the attacks, nationalists saw the RUC, which was almost wholly Protestant, as backing the loyalists and allowing the attacks to occur.<ref>{{cite web |url=http://www.serve.com/pfc/policing/submiss1.html |title=Submission to the Independent Commission into Policing |publisher=Serve.com |access-date=2 November 2008 |archive-date=22 November 2008 |archive-url=https://web.archive.org/web/20081122100048/http://www.serve.com/pfc/policing/submiss1.html |url-status=dead }}</ref> On 5 October 1968, a civil rights march in Derry was banned by the Northern Ireland government.<ref name="derrymarch">{{cite web |title=The Derry March: Main events of the day |author=Martin Melaugh |url=http://cain.ulst.ac.uk/events/derry/events.htm |work=[[Conflict Archive on the Internet]] (CAIN) |publisher=[[Ulster University]] |access-date=16 February 2008 |archive-date=23 November 2007 |archive-url=https://web.archive.org/web/20071123235747/http://cain.ulst.ac.uk/events/derry/events.htm |url-status=live }}</ref> When marchers defied the ban, RUC officers surrounded the marchers and beat them indiscriminately and without provocation.

A few days later, a student civil rights group, [[People's Democracy (Ireland)|People's Democracy]], was formed in Belfast.<ref name="cain1968"/> In late November, O'Neill promised the civil rights movement some concessions, but these were seen as too little by nationalists and too much by loyalists. On 1 January 1969, People's Democracy began a four-day march from Belfast to Derry, which was repeatedly harassed and attacked by loyalists. At [[Burntollet Bridge]], the marchers were attacked by about 200 loyalists, including some off-duty police officers, armed with iron bars, bricks, and bottles in a planned ambush. When the march reached Derry City, it was again attacked.

On 12 August, the loyalist [[Apprentice Boys of Derry]] were allowed to march along the edge of the Bogside. Taunts and missiles were exchanged between the loyalists and nationalist residents. After being bombarded with stones and petrol bombs from nationalists, the RUC, backed by loyalists, tried to storm the Bogside. The RUC used [[CS gas]], armoured vehicles, and water cannons, but were kept at bay by hundreds of nationalists.<ref>Russell Stetler.

Retrieved 17 March 2015.</ref> The continuous fighting, which became known as the [[Battle of the Bogside]], lasted for three days.

In response to events in Derry, nationalists held protests at RUC bases in Belfast and elsewhere. Some of these led to clashes with the RUC and attacks on RUC bases. In Belfast, loyalists responded by invading nationalist districts, burning houses and businesses. There were gun battles between nationalists and the RUC and between nationalists and loyalists. A group of about 30 IRA members was involved in the fighting in Belfast. The RUC deployed [[Shorland armoured car]]s mounted with heavy [[M1919 Browning machine gun|Browning machine guns]]. The Shorlands twice opened fire on a block of flats in a nationalist district, killing a nine-year-old boy named Patrick Rooney. RUC officers opened fire on rioters in Armagh, Dungannon, and Coalisland.<ref name="coogan"/>

Nationalists point to a number of events in these years to explain the upsurge in violence. One such incident was the Falls Curfew in July 1970, when 3,000 troops imposed a curfew on the nationalist Lower Falls area of Belfast, firing more than 1,500 rounds of ammunition in gun battles with the Official IRA and killing four people. Another was the [[Operation Demetrius|introduction of internment without trial in 1971]] (of 350 initial detainees, none were Protestants).<ref name="rkwalker">{{cite book |author=R.K.

Despite a temporary ceasefire in 1972 and talks with British officials, the Provisionals were determined to continue their campaign until the achievement of a united Ireland. The UK government in London, believing the Northern Ireland administration incapable of containing the security situation, sought to take over the control of law and order there. As this was unacceptable to the Northern Ireland Government, the British government pushed through emergency legislation (the [[Northern Ireland (Temporary Provisions) Act 1972]]) which suspended the unionist-controlled [[Parliament of Northern Ireland|Stormont]] parliament and government, and introduced "[[Direct rule over Northern Ireland|direct rule]]" from London. Direct rule was initially intended as a short-term measure; the medium-term strategy was to restore self-government to Northern Ireland on a basis that was acceptable to both unionists and nationalists. Agreement proved elusive, however, and the Troubles continued throughout the 1970s, 1980s, and the 1990s within a context of political deadlock. The existence of "no-go areas" in Belfast and Derry was a challenge to the authority of the British government in Northern Ireland, and the British Army demolished the barricades and re-established control over the areas in Operation Motorman on 31 July 1972.<ref name="coogan"/><ref name="jbb"/>

=== Sunningdale Agreement and UWC strike ===

In June 1973, following the publication of a British [[White Paper]] and a [[1973 Northern Ireland border poll|referendum]] in March on the status of Northern Ireland, a new parliamentary body, the [[Northern Ireland Assembly, 1973|Northern Ireland Assembly]], was established. [[1973 Northern Ireland Assembly election|Elections]] to this body were held on 28 June. In October 1973, mainstream nationalist and unionist parties, along with the British and Irish governments, negotiated the [[Sunningdale Agreement]], which was intended to produce a political settlement within Northern Ireland, but with a so-called "Irish dimension" involving the Republic. The agreement provided for "power-sharing" – the creation of an executive containing both unionists and nationalists; and a "Council of Ireland" – a body made up of ministers from Northern Ireland and the Republic that was designed to encourage cross-border co-operation.

Unionists were split over Sunningdale, which was also opposed by the IRA, whose goal remained nothing short of an end to the existence of Northern Ireland as part of the UK. Many unionists opposed the concept of power-sharing, arguing that it was not feasible to share power with nationalists who sought the destruction of the state. Perhaps more significant, however, was the unionist opposition to the "Irish dimension" and the Council of Ireland, which was perceived as being an all-Ireland parliament-in-waiting. Remarks by a young [[Social Democratic and Labour Party]] (SDLP) councillor [[Hugh Logue]] to an audience at [[Trinity College Dublin]] that Sunningdale was the tool "by which the Unionists will be trundled off to a united Ireland" also damaged chances of significant unionist support for the agreement. In January 1974, [[Brian Faulkner]] was narrowly deposed as UUP leader and replaced by [[Harry West]], although Faulkner retained his position as Chief Executive in the new government. A [[February 1974 United Kingdom general election|UK general election in February 1974]] gave the anti-Sunningdale unionists the opportunity to test unionist opinion with the slogan "Dublin is only a Sunningdale away", and the result galvanised their support: they won 11 of the 12 seats, winning 58% of the vote with most of the rest going to nationalists and pro-Sunningdale unionists.<ref name="coogan"/><ref name="jbb"/>

Ultimately, the Sunningdale Agreement was brought down by mass action on the part of loyalist paramilitaries and workers, who formed the [[Ulster Workers' Council]]. They organised a [[general strike]], the [[Ulster Workers' Council strike]]. This severely curtailed business in Northern Ireland and cut off essential services such as water and electricity. Nationalists argue that the British Government did not do enough to break this strike and uphold the Sunningdale initiative. There is evidence that the strike was further encouraged by [[MI5]], a part of their campaign to 'disorientate' British prime minister [[Harold Wilson]]'s government<ref>''Keeping Secrets'', [[London Review of Books]], April 1987.</ref> (see also [[Harold Wilson conspiracy theories]]). Faced with such opposition, the pro-Sunningdale unionists resigned from the power-sharing government and the new regime collapsed.

=== Proposal of an independent Northern Ireland ===
Even as his government deployed troops in August 1969, Wilson ordered a secret study of whether the British military could withdraw from Northern Ireland, including all 45 bases, such as the submarine school in Derry. The study concluded that the military could do so in three months, but if increased violence collapsed civil society, Britain would have to send in troops again. Without bases, to do so would be an invasion of Ireland; Wilson thus decided against a withdrawal.<ref name="ryder20190812">{{cite news |last=Ryder |first=Chris |date=12 August 2019 |title=Britain's secret plan to pull the Army out of Northern Ireland |language=en-GB |work=Belfast Telegraph |url=https://www.belfasttelegraph.co.uk/opinion/britains-secret-plan-to-pull-the-army-out-of-northern-ireland-38393646.html |access-date=25 May 2022 |issn=0307-1235}}</ref>

Wilson's cabinet discussed the more drastic step of complete British withdrawal from an independent Northern Ireland as early as February 1969, as one of various possibilities for the region including direct rule.<ref name="donnelly20000103">{{cite news |last=Donnelly |first=Rachel |title=Wilson weighed up direct rule in North |newspaper=The Irish Times |url=https://www.irishtimes.com/news/wilson-weighed-up-direct-rule-in-north-1.230278 |date=3 January 2000 |access-date=25 May 2022}}</ref> He wrote in 1971 that Britain had "responsibility without power" there,{{r|bourke20050103}} and secretly met with the IRA that year while leader of the opposition; his government in late 1974 and early 1975 again met with the IRA to negotiate a ceasefire. During the meetings, the parties discussed complete British withdrawal.{{r|fitzgerald2006}} Although the British government publicly stated that troops would stay as long as necessary, widespread fear from the [[Birmingham pub bombings]] and other IRA attacks in Britain itself increased support among MPs and the public for a military withdrawal.<ref name="sydney">{{cite news |title=Every Briton Now a Target for Death |newspaper=[[The Sydney Morning Herald]] |url=https://news.google.com/newspapers?id=ZXxXAAAAIBAJ&pg=1156%2C450835 |date=1 December 1974 |access-date=15 June 2016}}</ref>

The failure of Sunningdale and the effectiveness of the UWC strike against British authority were more evidence to Wilson of his 1971 statement. They led to the serious consideration in London of independence until November 1975. Had the withdrawal occurred – which Wilson supported but others, including [[James Callaghan]], opposed – the region would have become a separate [[dominion]].{{r|bourke20050103}}{{r|fitzgerald2006}} According to the secret plan, codenamed "Doomsday",<ref name="bbc20080911">{{cite news |title=Wilson had NI 'doomsday' plan |url=http://news.bbc.co.uk/2/hi/uk_news/politics/7610750.stm |publisher=BBC News |date=11 September 2008 |access-date=25 May 2022 |language=en-GB}}</ref> Britain would have had as little to do with the new "Ulster Dominion" as possible, with financial subsidies ending within five years.

The British negotiations with the IRA, an illegal organisation, angered the Republic's government. It did not know what was discussed but feared that the British were considering abandoning Northern Ireland. Irish Foreign Minister [[Garret FitzGerald]] discussed in a memorandum of June 1975 the possibilities of orderly withdrawal and independence, [[Repartition of Ireland|repartition of the island]], or a collapse of Northern Ireland into civil war and anarchy. The memorandum preferred a negotiated independence as the best of the three "worst case scenarios", but concluded that the Irish government could do little.{{r|fitzgerald2006}}

The Irish government had already failed to prevent a crowd from burning down the [[Embassy of the United Kingdom, Dublin|British Embassy]] in 1972. It believed that it could not enlarge the country's small army of 12,500 men without negative consequences. A civil war in Northern Ireland would cause many deaths there and severe consequences for the Republic, as the public would demand that it intervene to protect nationalists. FitzGerald warned Callaghan that the failure to intervene, despite Ireland's inability to do so, would "threaten democratic government in the Republic", which would jeopardise British and European security against [[Communist]] and other foreign nations.{{r|fitzgerald2006}}

In December, a month after the Birmingham pub bombings killed 21 people, the IRA declared a ceasefire; this would theoretically last throughout most of the following year. The ceasefire notwithstanding, sectarian killings escalated in 1975, along with internal feuding between rival paramilitary groups. This made 1975 one of the "bloodiest years of the conflict".<ref name="taylorloyalists"/>

On 5 April 1975, Irish republican paramilitary members killed a UDA [[volunteer (Ulster loyalist)|volunteer]] and four Protestant [[civilians]] in a [[gun]] and [[bomb]] [[Mountainview Tavern attack|attack at the Mountainview Tavern]] on the [[Shankill Road]], [[Belfast]].

On 31 July 1975 at Buskhill, outside [[Newry]], popular Irish [[cabaret]] band [[the Miami Showband]] was returning home to Dublin after a gig in [[Banbridge]] when it was [[Miami Showband killings|ambushed by gunmen]] from the UVF Mid-Ulster Brigade wearing British Army uniforms at a bogus military [[Security checkpoint|roadside checkpoint]] on the main [[A1 road (Northern Ireland)|A1 road]]. Three of the bandmembers, two Catholics and a Protestant, were shot dead, while two of the UVF men were killed when the bomb they had loaded onto the band's minibus detonated prematurely. The following January, eleven Protestant workers were gunned down in [[Kingsmill massacre|Kingsmill, South Armagh]] after having been ordered off their bus by an armed republican gang, which called itself the [[South Armagh Republican Action Force]]. This resulted in 10 fatalities, with one man surviving despite being shot 18 times.

=== Late 1970s ===

By the late 1970s, [[war-weariness]] was visible in both communities. One sign of this was the formation of the [[Community for Peace People|Peace People]], which won the [[Nobel Peace Prize]] in 1976. The Peace People organised large demonstrations calling for an end to paramilitary violence. Their campaign lost momentum, however, after they appealed to the nationalist community to provide information on the IRA to security forces.<ref name="dooley">Brian Dooley.

Successive British Governments, having failed to achieve a political settlement, tried to "normalise" Northern Ireland. Aspects included the removal of internment without trial and the removal of [[Special Category Status|political status]] for paramilitary prisoners. From 1972 onward, paramilitaries were tried in juryless [[Diplock courts]] to avoid intimidation of jurors. On conviction, they were to be treated as ordinary criminals. Resistance to this policy among republican prisoners led to more than 500 of them in the [[Maze prison]] initiating the [[Blanket protest|"blanket"]] and [[Dirty protest|"dirty"]] protests. Their protests culminated in [[hunger strike]]s in 1980 and 1981, aimed at the restoration of political status, as well as other concessions.<ref name="coogan"/><ref name="jbb"/>

In the [[1981 Irish hunger strike]], ten republican prisoners (seven from the Provisional IRA and three from the INLA) died of starvation. The first hunger striker to die, [[Bobby Sands]], was elected to Parliament on an [[Anti-H-Block]] ticket, as was his election agent [[Owen Carron]] following Sands's death. The hunger strikes resonated among many nationalists; over 100,000 people<ref name="cainhsc">{{cite web |title=The Hunger Strike of 1981 – A Chronology of Main Events |url=http://cain.ulst.ac.uk/events/hstrike/chronology.htm |publisher=CAIN |access-date=26 May 2007 |archive-date=6 December 2010 |archive-url=https://web.archive.org/web/20101206165221/http://cain.ulst.ac.uk/events/hstrike/chronology.htm |url-status=live}}</ref> attended Sands's funeral mass in West Belfast and thousands attended those of the other hunger strikers.

The IRA's "Long War" was boosted by large donations of arms from [[Libya]] in the 1980s (see [[Provisional IRA arms importation]]) partly due to [[Muammar Gaddafi]]'s anger at British Prime Minister [[Margaret Thatcher]]'s government for assisting the [[Reagan]] government's [[1986 bombing of Libya]], which had allegedly killed one of Gaddafi's children.

Towards the end of the decade, the British Army tried to soften its public appearance to residents in communities such as Derry in order to improve relations between the local community and the military. Soldiers were told not to use the telescopic sights on their rifles to scan the streets, as civilians believed they were being aimed at. Soldiers were also encouraged to wear berets when manning checkpoints (and later other situations) rather than helmets, which were perceived as militaristic and hostile. The system of complaints was overhauled – if civilians believed they were being harassed or abused by soldiers in the streets or during searches and made a complaint, they would never find out what action (if any) was taken. The new regulations required an officer to visit the complainants house to inform them of the outcome of their complaint.<ref>Moloney, Ed. ''A Secret History of the IRA''.

In the 1980s, loyalist paramilitary groups—the Ulster Volunteer Force, the Ulster Defence Association, and [[Ulster Resistance]]—imported arms and explosives from [[South Africa]].<ref name="taylorloyalists"/> The weapons obtained were divided between the groups, although some of the weaponry (such as [[rocket-propelled grenade]]s) were hardly used. In 1987, the [[Irish People's Liberation Organisation]] (IPLO), a breakaway faction of the INLA, engaged in a bloody feud against the INLA which weakened the INLA's presence in some areas. By 1992, the IPLO was destroyed by the Provisionals for its involvement in drug dealing, thus ending the feud.<ref name="coogan"/>

In the 1990s, the IRA came up with a new plan to restrict British Army foot patrols near Crossmaglen.

=== Downing Street mortar attack ===
[[File:1991 Mortar attack on Downing Street.jpg|thumbnail|right|Police officers looking at a burned van used by the IRA in the 1991 mortar attack on 10 Downing Street]]

On 7 February 1991, the IRA attempted to assassinate prime minister [[John Major]] and his [[war cabinet]] by [[Downing Street mortar attack|launching]] a [[Mortar (weapon)|mortar]] at [[10 Downing Street]] while they were gathered there to discuss the [[Gulf War]].<ref name=IN>{{cite web| url = https://irishnews.com/news/2017/12/07/news/terror-plot-reminiscent-of-ira-attacks-1204792/| title = Terror plot reminiscent of IRA attacks| date = 7 December 2017}}</ref> The mortar bombing caused only four injuries, two of which were to police officers, while Major and the entire war cabinet were unharmed.<ref name=IN/>

=== First ceasefire ===
After a prolonged period of background political manoeuvring, during which the 1992 [[Baltic Exchange bombing|Baltic Exchange]] and [[1993 Bishopsgate bombing]]s occurred in London, both loyalist and republican paramilitary groups declared ceasefires in 1994.
<!-- [[WP:NFCC]] violation: [[File:Irish News - Shankill.jpg|thumbnail|Aftermath of the 1993 Shankill Road bombing]] -->
The year leading up to the ceasefires included a [[mass shooting]] in [[Castlerock]], County Londonderry in which [[1993 Castlerock killings|four people were killed]]. The IRA responded with the [[Shankill Road bombing]] in October 1993, which aimed to kill the UDA leadership, but instead killed eight Protestant civilian shoppers and a low-ranking UDA member, as well as one of the perpetrators, who was killed when the bomb detonated prematurely. The UDA responded with attacks in nationalist areas including [[Greysteel massacre|a mass shooting]] in [[Greysteel]], in which eight civilians were killed – six Catholics and two Protestants.<ref name="coogan"/>

On 16 June 1994, just before the ceasefires, the Irish National Liberation Army [[1994 Shankill Road killings|killed three UVF members in a gun attack on the Shankill Road]]. In revenge, three days later the UVF [[Loughinisland massacre|killed six civilians in a shooting at a pub]] in [[Loughinisland]], County Down. The IRA, in the remaining month before its ceasefire, killed four senior loyalist paramilitaries, three from the UDA and one from the UVF. On 31 August 1994, the IRA declared a [[ceasefire]]. The loyalist paramilitaries, temporarily united in the "[[Combined Loyalist Military Command]]", reciprocated six weeks later. Although these ceasefires failed in the short run, they marked an effective end to large-scale political violence, as they paved the way for the final ceasefires.<ref name="coogan"/><ref name="jbb"/>

In 1995, the United States appointed [[George J. Mitchell]] as the [[United States Special Envoy for Northern Ireland]]. Mitchell was recognised as being more than a token envoy and as representing a President ([[Bill Clinton]]) with a deep interest in events.<ref>{{cite news|url=http://news.bbc.co.uk/1/hi/northern_ireland/2927845.stm|title=US policy and Northern Ireland|publisher=BBC News|date=8 April 2003|access-date=24 May 2009|archive-date=22 May 2004|archive-url=https://web.archive.org/web/20040522041845/http://news.bbc.co.uk/1/hi/northern_ireland/2927845.stm|url-status=live}}</ref> The British and Irish governments agreed that Mitchell would chair an international commission on disarmament of paramilitary groups.<ref>{{cite news|url=https://query.nytimes.com/gst/fullpage.html?res=9A03EEDD1139F933A05752C1A963958260&scp=2&sq=%22George+Mitchell%22+and+%22northern+Ireland%22&st=nyt|title=A Break in the Irish Impasse|work=The New York Times|date=30 November 1995|access-date=13 February 2017|archive-date=23 June 2020|archive-url=https://web.archive.org/web/20200623095555/https://www.nytimes.com/1995/11/30/opinion/a-break-in-the-irish-impasse.html|url-status=live}}</ref>

=== Second ceasefire ===
On 9 February 1996, less than two years after the declaration of the ceasefire, the IRA revoked it with the [[Docklands bombing]] in the Canary Wharf area of London, killing two people, injuring 39 others,<ref>{{cite news|url=http://news.bbc.co.uk/onthisday/hi/dates/stories/february/10/newsid_2539000/2539265.stm|title=BBC On This Day 1996: Docklands bomb ends IRA ceasefire|publisher=BBC News|date=10 February 1996|access-date=3 October 2016|archive-date=21 March 2012|archive-url=https://web.archive.org/web/20120321012534/http://news.bbc.co.uk/onthisday/hi/dates/stories/february/10/newsid_2539000/2539265.stm|url-status=live}}</ref> and causing £85&nbsp;million in damage to the city's financial centre.

[[File:South Quay bombing - 9.2.96.jpg|alt=A picture of a large office building which has been very badly damaged.|thumb|The destruction caused by the Docklands bombing in London, 1996]]

The attack was followed by several more, most notably the [[1996 Manchester bombing]], which destroyed a large area of the centre of the city on 15 June. It was the largest bomb attack in Britain since [[World War II]]. While the attack avoided any fatalities due to a telephone warning and the rapid response of the emergency services, over 200 people were injured in the attack, many of them outside the established cordon. The damage caused by the blast was estimated at £411&nbsp;million. [[Lance bombardier]] Stephen Restorick, the last British soldier killed during the Troubles, was shot dead at a checkpoint on the Green Rd near Bessbrook on 12 February 1997 by the IRA's [[South Armagh Sniper (1990–1997)|South Armagh sniper]].<ref>{{cite news|url=https://www.telegraph.co.uk/news/uknews/northernireland/4958589/Northern-Ireland-shootings-The-last-soldier-murdered.html|title=Northern Ireland shootings: The last soldier murdered|work=The Telegraph|date=9 March 2009|access-date=9 May 2017|last1=Bingham|first1=John|archive-date=14 November 2017|archive-url=https://web.archive.org/web/20171114015230/http://www.telegraph.co.uk/news/uknews/northernireland/4958589/Northern-Ireland-shootings-The-last-soldier-murdered.html|url-status=live}}</ref>

The IRA reinstated their ceasefire in July 1997, as negotiations for the document that became known as the Good Friday Agreement began without Sinn Féin. In September of the same year, Sinn Féin signed [[Mitchell Principles|the Mitchell Principles]] and were admitted to the talks. The UVF was the first paramilitary grouping to split as a result of their ceasefire, spawning the [[Loyalist Volunteer Force]] (LVF) in 1996. In December 1997, the INLA assassinated LVF leader [[Billy Wright (loyalist)|Billy Wright]], leading to a series of revenge killings by loyalist groups. A group split from the Provisional IRA and formed the [[Real IRA]] (RIRA).<ref>{{cite web|url=https://www.theguardian.com/uk/2009/mar/10/real-ira-continuity|title=Explainer: Real IRA and Continuity IRA|work=The Guardian|location=London|date=10 March 2009|access-date=13 December 2016|archive-date=25 December 2018|archive-url=https://web.archive.org/web/20181225072529/https://www.theguardian.com/uk/2009/mar/10/real-ira-continuity|url-status=live}}</ref>

In August 1998, [[Omagh bombing|a Real IRA bomb]] in [[Omagh]] killed 29 civilians, the most by a single bomb during the Troubles.<ref name="records"/> This bombing discredited "[[dissident republican]]s" and their campaigns in the eyes of many who had previously supported the Provisionals' campaign.

The INLA also declared a ceasefire after the Good Friday Agreement. Since then, most paramilitary violence has been directed at their "own" communities and at other factions within their organisations. The UDA, for example, has feuded with their fellow loyalists the UVF on two occasions since 2000. There have been internal struggles for power between "brigade commanders" and involvement in [[organised crime]].<ref>{{cite news|author=Henry McDonald|url=https://www.theguardian.com/uk/2006/jul/30/northernireland.henrymcdonald|title=New feud rips apart the UDA|work=The Guardian|location=London|date=30 July 2006|access-date=13 December 2016|archive-date=7 November 2018|archive-url=https://web.archive.org/web/20181107104051/https://www.theguardian.com/uk/2006/jul/30/northernireland.henrymcdonald|url-status=live}}</ref>

=== Political process ===

[[File:Unidentified irish mural.jpg|thumb|A republican mural in Belfast during the mid-1990s bidding "safe home" ([[Slán Abhaile]]) to British troops. Security normalisation was one of the key points of the Good Friday Agreement.]]

After the ceasefires, talks began between the main political parties in Northern Ireland to establish political agreement. These talks led to the Good Friday Agreement of 1998. This Agreement restored self-government to Northern Ireland on the basis of "power-sharing". In 1999, an executive was formed consisting of the four main parties, including Sinn Féin. Other important changes included the reform of the RUC, renamed as the [[Police Service of Northern Ireland]], which was required to recruit at least a 50% quota of Catholics for ten years, and the removal of [[Diplock courts]] under the [[Justice and Security (Northern Ireland) Act 2007]].<ref>[http://www.nio.gov.uk/media-detail.htm?newsID=13803 Northern Ireland becoming a more normalised society] {{Webarchive|url=https://web.archive.org/web/20070108133243/http://www.nio.gov.uk/media-detail.htm?newsID=13803 |date=8 January 2007 }} – Northern Ireland Office, 27 November 2006.</ref>

A security normalisation process also began as part of the treaty, which comprised the progressive closing of redundant British Army barracks, border observation towers, and the withdrawal of all forces taking part in Operation Banner – including the resident battalions of the [[Royal Irish Regiment (1992)|Royal Irish Regiment]] – that would be replaced by [[19th Light Brigade (United Kingdom)|an infantry brigade]], deployed in ten sites around Northern Ireland but with no operative role in the province.<ref name="MODreport">{{cite report |date=23 July 2007 |title=Ministry of Defence Annual Report and Accounts 2006–2007 |url=http://www.official-documents.gov.uk/document/hc0607/hc06/0697/0697.pdf |publisher=[[Ministry of Defence (United Kingdom)|Ministry of Defence]] |access-date=24 February 2016 |id=HC 697 |archive-date=24 August 2012 |archive-url=https://web.archive.org/web/20120824170853/http://www.official-documents.gov.uk/document/hc0607/hc06/0697/0697.pdf |url-status=live }}</ref>

The power-sharing Executive and Assembly were suspended in 2002, when unionists withdrew following "[[Stormontgate]]", a controversy over allegations of an IRA spy ring operating at Stormont. There were ongoing tensions about the Provisional IRA's failure to disarm fully and sufficiently quickly. IRA decommissioning has since been completed (in September 2005) to the satisfaction of most parties.<ref>{{cite news|title=IRA 'has destroyed all its arms'|url=http://news.bbc.co.uk/1/hi/northern_ireland/4283444.stm|publisher=BBC|date=26 September 2005|access-date=6 April 2007|archive-date=25 February 2007|archive-url=https://web.archive.org/web/20070225155758/http://news.bbc.co.uk/1/hi/northern_ireland/4283444.stm|url-status=live}}</ref>

A feature of Northern Ireland politics since the Agreement has been eclipsed in electoral terms of parties such as the [[SDLP]] and [[Ulster Unionist Party]] (UUP) by rival parties such as Sinn Féin and the DUP. Similarly, although political violence is greatly reduced, sectarian animosity has not disappeared. Residential areas are more segregated between Catholic nationalists and Protestant unionists than ever.<ref>Margaret Scanlan.

On 8 May 2007, devolved government returned to Northern Ireland. DUP leader [[Ian Paisley]] and Sinn Féin's [[Martin McGuinness]] took office as First Minister and deputy First Minister, respectively.<ref>{{cite web|title=BBC|url=https://www.bbc.co.uk/history/people/ian_paisley|access-date=25 February 2016|archive-date=25 September 2015|archive-url=https://web.archive.org/web/20150925062203/http://www.bbc.co.uk/history/people/ian_paisley|url-status=live}}</ref>

== Support outside Northern Ireland ==

===Arms importation===
{{further information|Provisional IRA in the Republic of Ireland|Provisional Irish Republican Army arms importation|Official Irish Republican Army#Support|Irish National Liberation Army#Arms importation}}
Both Republican and Loyalist paramilitaries sought to obtain weapons outside of [[Northern Ireland]] in order to achieve their objectives. Irish Republican paramilitaries received the vast majority of external support. Over the years, the Provisional IRA imported arms from external sources such as sympathisers in the [[Republic of Ireland]], [[Irish diaspora]] communities within the [[Anglosphere]], mainland Europe, the [[Palestine Liberation Organization]], and [[Libya]]n leader [[Muammar Gaddafi]]. The [[Soviet Union]] and [[North Korea]] supplied the Official IRA with 5,000 weapons,<ref>[http://www.belfasttelegraph.co.uk/news/northern-ireland/official-ira-doomsday-bunkers-may-still-contain-thousands-of-weapons-31267631.html "Official IRA "doomsday" bunkers may still contain thousands of weapons"] {{webarchive |url=https://web.archive.org/web/20160305225253/http://www.belfasttelegraph.co.uk/news/northern-ireland/official-ira-doomsday-bunkers-may-still-contain-thousands-of-weapons-31267631.html |date=5 March 2016}}. ''Belfast Telegraph''. 31 May 2015.</ref> and the INLA received considerable arms from overseas as well.

The IRA's primary external support was from the Republic of Ireland, whose safe haven allowed the group to raise legal and illegal funds, organise and train, and manufacture a large number of firearms and explosives with ease and then smuggled them into Northern Ireland and England.<ref name="HWEFA">{{cite news|title=Support in Republic during Troubles 'key for IRA', book claims|url=https://www.irishnews.com/news/northernirelandnews/2019/04/06/news/headline-1591367/|author=John Manley|date=6 April 2019|publisher=[[The Irish News]]}}</ref> The IRA's primary weapon in the Republic was [[explosive]]s (including [[gelignite]], [[fertiliser]], and [[ANFO]]), which were responsible for the vast majority of the bombings in Northern Ireland and England throughout the conflict.<ref name="HWEFA"/> While the [[plastic explosive]] [[Semtex]] donated by Gaddafi was appreciated and infamous in IRA bombing campaigns, they were actually sparsely used. Notable events of IRA bombs of Irish origin included Bloody Friday, the Warrenpoint ambush, the assassination of Lord Mountbatten, and the Hyde Park and Regent's Park bombings.

Loyalist paramilitaries also received support, mainly from Protestant supporters in Canada, England, and Scotland (including members of the Orange Order). From 1979 to 1986, loyalist paramilitaries imported up to 100 machine guns and "as many rifles, grenade launchers, magnum revolvers and hundreds of thousands of rounds of ammunition from Canada."<ref>{{cite book|title=UVF – The Endgame|author= Henry McDonald and Jim Cusack|date=1997|page=119|publisher=[[Poolbeg Press]]}}</ref> Members of the [[Grand Orange Lodge of Scotland]] sent gelignite explosives to UDA and UVF members.<ref>{{cite web|url=https://www.heraldscotland.com/news/12445506.revealed-how-scots-loyalists-sent-gelignite-to-paramilitaries-secret-memo-says-explosives-were-shipped-in-small-boats/|title=Revealed: how Scots loyalists sent gelignite to paramilitaries.

Irish Republican and Loyalist militants also received significant funding from groups, individuals, and state actors outside Northern Ireland.

The primary reason for this is the relative ease of raising funds within these communities. Sympathy for the cause is greatest within the originating community. Those concerned also have the local knowledge which facilitates crime or the direct intimidation of individuals from whom money is sought. The fact that Northern Ireland remains predominantly a cash economy also encourages a local focus, as it facilitates money laundering and makes it difficult for the law enforcement agencies to trace transactions.<ref name="DDBVGEW"/></blockquote>

== Collusion between security forces and paramilitaries ==
[[File:Collusion is not an illusion.jpg|thumb|A republican mural in Belfast with the slogan "Collusion is not an illusion"]]
There were many incidents of [[collusion]] between the British state security forces (the British Army and RUC) and loyalist paramilitaries. This included soldiers and policemen taking part in loyalist attacks while off-duty, giving weapons and intelligence to loyalists, not taking action against loyalists, and hindering police investigations. The [[Desmond Lorenz de Silva|De Silva]] Report found that, during the 1980s, 85% of the intelligence loyalists used to target people came from the security forces,<ref>[https://www.bbc.co.uk/news/uk-northern-ireland-20662412 "Pat Finucane murder: 'Shocking state collusion', says PM"] {{webarchive |url=https://web.archive.org/web/20210125004348/https://www.bbc.co.uk/news/uk-northern-ireland-20662412 |date=25 January 2021}}, BBC News.

== Shoot-to-kill allegations ==
{{main|Shoot-to-kill policy in Northern Ireland}}
Republicans allege that the security forces operated a shoot-to-kill policy rather than arresting IRA suspects. The security forces denied this and pointed out that six of the eight IRA men killed in the [[Loughgall ambush]] in 1987 were heavily armed. On the other hand, the [[Operation Flavius|shooting of three unarmed IRA members]] in [[Gibraltar]] by the [[Special Air Service]] ten months later appeared to confirm suspicions among republicans and in the British and Irish media of a tacit British shoot-to-kill policy of suspected IRA members.<ref name="maxinewilliams">Maxine Williams.[http://www.rcgfrfi.easynet.co.uk/larkin_pubs/older/motr/motr_all.htm ''Murder on the Rock''] {{Webarchive|url=https://web.archive.org/web/20070204153946/http://www.rcgfrfi.easynet.co.uk/larkin_pubs/older/motr/motr_all.htm |date=4 February 2007 }} , rcgfrfi.easynet.co.uk.

== Parades issue ==
{{Main|Parades in Northern Ireland|Drumcree conflict|Quinn brothers' killings}}
[[File:Orangemen parade in Bangor, 12 July 2010 - geograph - 1964645.jpg|thumb|Orangemen [[Orange walk|marching]] in [[Bangor, County Down|Bangor]] on the [[Twelfth of July]] 2010]]

Inter-communal tensions rise and violence often breaks out during the "marching season" when the Protestant Orange Order parades take place across Northern Ireland. The parades are held to commemorate William of Orange's victory in the [[Battle of the Boyne]] in 1690, which secured the [[Protestant Ascendancy]] and [[British rule in Ireland]]. One particular flashpoint which has caused continuous annual strife is the Garvaghy Road area in [[Portadown]], where an Orange parade from [[Drumcree Church]] passes through a mainly nationalist estate off the Garvaghy Road. This parade has now been banned indefinitely, following nationalist riots against the parade and loyalist counter-riots against its banning.

In 1995, 1996, and 1997, there were several weeks of prolonged rioting throughout Northern Ireland over the impasse at Drumcree. A number of people died in this violence, including a Catholic taxi driver killed by the [[Loyalist Volunteer Force]], and three (of four) nominally Catholic brothers (from a mixed-religion family) died when their house in [[Ballymoney]] [[Quinn brothers' killings|was petrol-bombed]].<ref>{{cite news|title=Michael McGoldrick, 64, Activist in Ulster, Dies|url=https://www.nytimes.com/2006/04/06/world/europe/06mcgoldrick.html|newspaper=The New York Times|date=6 April 2006|access-date=13 February 2017|archive-date=7 November 2018|archive-url=https://web.archive.org/web/20181107110013/https://www.nytimes.com/2006/04/06/world/europe/06mcgoldrick.html|url-status=live}}</ref><ref>{{cite news|author=Angelique Chrisafis|title=Police hold six over loyalist turf war deaths|url=https://www.theguardian.com/politics/2005/aug/05/uk.northernireland1|newspaper=The Guardian|location=London |date=5 August 2005|access-date=13 December 2016|archive-date=7 November 2018|archive-url=https://web.archive.org/web/20181107104317/https://www.theguardian.com/politics/2005/aug/05/uk.northernireland1|url-status=live}}</ref><ref>{{cite news|url=http://news.bbc.co.uk/onthisday/hi/dates/stories/july/12/newsid_2500000/2500503.stm|title=1998: Children die in Drumcree protests|publisher=BBC News|date=12 July 1986|access-date=27 May 2008|archive-date=7 March 2008|archive-url=https://web.archive.org/web/20080307121057/http://news.bbc.co.uk/onthisday/hi/dates/stories/july/12/newsid_2500000/2500503.stm|url-status=live}}</ref>

The impact of the Troubles on the ordinary people of Northern Ireland has been compared to that of the [[The Blitz|Blitz]] on the people of London.<ref>Dervla Murphy. ''[[A Place Apart]]''. Penguin Books, 1978, p. 134.<!-- ISBN needed --></ref> The stress resulting from bomb attacks, street disturbances, security checkpoints, and the constant military presence had the strongest effect on children and young adults.<ref>Murphy, p. 209.</ref> There was also the fear that local paramilitaries instilled in their respective communities with the [[Corporal punishment|punishment beatings]], "romperings", and the occasional [[tarring and feathering]] meted out to individuals for various purported infractions.<ref name="nelson126">Sarah Nelson. ''Ulster's Uncertain Defenders: Protestant Political, Paramilitary and Community Groups and the Northern Ireland Conflict'', 1984, Belfast: Appletree Press. p. 126.<!-- ISBN needed --></ref>

In addition to the violence and intimidation, there was chronic unemployment and a severe housing shortage. Many people were rendered homeless as a result of intimidation or having their houses burnt, and urban redevelopment played a role in the social upheaval. Belfast families faced being transferred to new, alien estates when older, decrepit districts such as [[Sailortown, Belfast|Sailortown]] and the [[Pound Loney]] were being demolished. According to social worker and author Sarah Nelson, this problem of homelessness and disorientation contributed to the breakdown of the normal fabric of society, allowing for paramilitaries to exert a strong influence in certain districts.<ref name="nelson126"/> Vandalism was also a major problem. In the 1970s, there were 10,000 vandalised empty houses in Belfast alone. Most of the vandals were aged between eight and thirteen.<ref>Murphy, p. 210.</ref>

According to one historian of the conflict, the stress of the Troubles engendered a breakdown in the previously strict sexual morality of Northern Ireland, resulting in a "confused [[hedonism]]" in respect of personal life.<ref>[[Jack Holland (writer)|Jack Holland]]. ''Hope Against History: The Course of Conflict in Northern Ireland'', 1999, pp. 12–13. <!-- ISBN/ISSN needed --></ref> In Derry, [[Legitimacy (family law)|illegitimate births]] and [[alcoholism]] increased for women and the divorce rate rose.<ref>Murphy, p. 80.</ref> Teenage alcoholism was also a problem, partly as a result of the drinking clubs established in both loyalist and republican areas. In many cases, there was little parental supervision of children in some of the poorer districts.<ref>Murphy, pp. 279–282.</ref> The Department of Health has looked at a report written in 2007 by Mike Tomlinson of [[Queen's University of Belfast|Queen's University]], which asserted that the legacy of the Troubles has played a substantial role in the current rate of suicide in Northern Ireland.<ref>BBC News, 4 July 2007. Retrieved 29 September 2008.</ref>

Further social issues arising from the Troubles include [[antisocial behavior]] and an aversion towards political participation. According to one historian, children raised during the Troubles were found to develop similar antisocial external behaviors as children similarly born in regions of conflict, notably those born and raised during [[World War II]].<ref>Muldoon, ''Children of the Troubles: The Impact of Political Violence in Northern Ireland'', p. 461</ref> Further studies into the impact of violence on the psychological development of children in Northern Ireland also found that those raised during the Troubles were more likely to be averse towards political participation, noting that while older generations still actively associated with their own social and political groups, younger generations became wary of such groups as social and political divisions continued to expand during the thirty years of the Troubles.<ref>Muldoon, ''Children of the Troubles: The Impact of Political Violence in Northern Ireland'', p. 464</ref>

Peace lines, which were built in Northern Ireland during the early years of the Troubles, remain in place.<ref>{{Cite web|url=https://www.pri.org/stories/2020-01-14/northern-ireland-still-divided-peace-walls-20-years-after-conflict|title=Northern Ireland still divided by peace walls 20 years after conflict|website=The World from PRX|access-date=20 December 2020|archive-date=26 November 2020|archive-url=https://web.archive.org/web/20201126042135/https://www.pri.org/stories/2020-01-14/northern-ireland-still-divided-peace-walls-20-years-after-conflict|url-status=live}}</ref>

According to a 2022 poll, 69% of Irish nationalists polled believe there was no option but "violent resistance to British rule during the Troubles".<ref>{{cite news |last=Breen |first=Suzanne |title=Seven in 10 nationalists agree with Michelle O'Neill that there was 'no alternative' to IRA's campaign of violence, new poll reveals |url=https://www.belfasttelegraph.co.uk/news/politics/seven-in-10-nationalists-agree-with-michelle-oneill-that-there-was-no-alternative-to-iras-campaign-of-violence-new-poll-reveals/41924287.html |work=Belfast Telegraph |date=19 August 2022}}</ref>

In ''The Politics of Antagonism: Understanding Northern Ireland'', [[Brendan O'Leary]] and [[John McGarry]] point out that "nearly two per cent of the population of Northern Ireland have been killed or injured through political violence [...] If the equivalent ratio of victims to population had been produced in Great Britain in the same period some 100,000 people would have died, and if a similar level of political violence had taken place, the number of fatalities in the USA would have been over 500,000".<ref>Brendan O'Leary and John McGarry.

In 2010, it was estimated that 107,000 people in Northern Ireland suffered some physical injury as a result of the conflict. On the basis of data gathered by the [[Northern Ireland Statistics and Research Agency]], the [[Victims' Commissioner|Victims Commission]] estimated that the conflict resulted in 500,000 'victims' in Northern Ireland alone. It defines 'victims' are those who are directly affected by 'bereavement', 'physical injury', or 'trauma' as a result of the conflict.<ref>Simon Cunningham. "Troubles created 500 000 victims says official body", ''The Irish News'', 27 September 2011.</ref>

Most killings took place within Northern Ireland, especially in Belfast and County Armagh. Most of the killings in Belfast took place in the west and north of the city. [[Dublin]], London and [[Birmingham]] were also affected, albeit to a lesser degree than Northern Ireland itself. Occasionally, the IRA attempted or carried out attacks on British targets in Gibraltar, Germany, Belgium and the Netherlands.<ref>{{cite news|url=https://apnews.com/dfa72018b4c95d84d74ccc418561acda|title=Two Suspected IRA members Arrested in Belgium, Netherlands|website=AP NEWS|access-date=20 October 2019|archive-date=23 June 2019|archive-url=https://web.archive.org/web/20190623161305/https://apnews.com/dfa72018b4c95d84d74ccc418561acda|url-status=live}}</ref><ref>{{Cite news|url=https://www.nytimes.com/1979/08/29/archives/ira-sets-off-bomb-at-belgian-concert-15-persons-are-hurt-in.html|title=I.r.a.
