The Troubles (Irish: Na Trioblóidí) were an ethno-nationalist conflict in Northern Ireland that lasted for about 30 years from the late 1960s to 1998. Also known internationally as the Northern Ireland conflict, it began in the late 1960s and is usually deemed to have ended with the Good Friday Agreement of 1998. Although the Troubles mostly took place in Northern Ireland, at times violence spilled over into parts of the Republic of Ireland, England, and mainland Europe.
Sometimes described as an asymmetric or irregular war or a low-intensity conflict, the Troubles were a political and nationalistic struggle fuelled by historical events, with a strong ethnic and sectarian dimension, fought over the status of Northern Ireland. Unionists and loyalists, who for historical reasons were mostly Ulster Protestants, wanted Northern Ireland to remain within the United Kingdom. Irish nationalists and republicans, who were mostly Irish Catholics, wanted Northern Ireland to leave the United Kingdom and join a united Ireland. Despite the division between Protestants and Catholics, it was not a religious war.
The conflict began during a campaign by the Northern Ireland Civil Rights Association to end discrimination against the Catholic-nationalist minority by the Protestant-unionist government and local authorities. 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 August 1969 riots and the deployment of British troops, in what became the British Army's longest operation. "Peace walls" were built in some areas to keep the two communities apart. Some Catholics initially welcomed the British Army as a more neutral force than the RUC, but soon came to see it as hostile and biased, particularly after Bloody Sunday in 1972.
The main 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 campaigns, primarily against republicans. There were incidents of collusion between British state forces and loyalist paramilitaries. The Troubles involved numerous riots, mass protests, and acts of civil disobedience, and led to increased segregation and the creation of temporary no-go areas.
More than 3,500 people were killed in the conflict, of whom 52% were civilians, 32% were members of the British security forces, and 16% were members of paramilitary groups. Republican paramilitaries were responsible for 60% of total deaths, followed by loyalist paramilitaries at 30% and security forces at 10%. Loyalists were responsible for 48% of all civilian deaths, however, followed by republicans at 39% and security forces at 10%.
The Northern Ireland peace process led to paramilitary ceasefires and talks between the main political parties, which resulted in the Good Friday Agreement of 1998. This Agreement restored self-governance to Northern Ireland on the basis of "power-sharing" and it included acceptance of the principle of consent, commitment to civil and political rights, parity of esteem between the two communities, police reform, paramilitary disarmament, and early release of paramilitary prisoners.
There has been sporadic violence since the Agreement, including punishment attacks, loyalist gangs' control of major organised crime rackets (e.g., drugs supply, community coercion and violence, intimidation), and violent crime linked to dissident republican groups.
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 in 1660, the English 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 ..."; as does the similar act in Scotland: "The king's most excellent majesty, considering that by the late troubles diverse of his subjects ..." (Scottish Parliament 1662); and by the Irish Parliament in the 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). The term was used to describe the Irish revolutionary period in the early twentieth century. It was subsequently adopted to refer to the escalating violence in Northern Ireland after 1969.
In 1609, Scottish and English settlers, known as planters, were given land escheated from the native Irish in the Plantation of Ulster. Coupled with Protestant immigration to "unplanted" areas of Ulster, particularly Antrim and 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 that curtailed the religious, legal, and political rights of anyone (including both Catholics and Protestant Dissenters, such as Presbyterians) 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" and Catholic "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.
Following the foundation of the 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 of Orange, dates from this period and remains active to this day.
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 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 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.
