Main article: The Troubles
The Troubles, starting in the late 1960s, consisted of about thirty years of recurring acts of intense violence between elements of Northern Ireland's nationalist community (principally Roman Catholic) and unionist community (principally Protestant) during which 3,254 people were killed.[23] The conflict was caused by the disputed status of Northern Ireland within the United Kingdom and the discrimination against the nationalist minority by the dominant unionist majority.[24] From 1967 to 1972 the Northern Ireland Civil Rights Association, modelling itself on the US civil rights movement, led a campaign of civil resistance to anti-Catholic discrimination in housing, employment, policing, and electoral procedures (the franchise being limited to property-owning rate-payers, thereby excluding most Catholics). However NICRA's campaign, and the reaction to it, proved to be a precursor to a more violent period.[25] As early as 1969, armed campaigns of paramilitary groups began, including the Provisional IRA campaign of 1969–1997 which was aimed at the end of British rule in Northern Ireland and the creation of a new "all-Ireland", "thirty-two county" Irish Republic, and the Ulster Volunteer Force, formed in 1966 in response to the perceived erosion of both the British character and unionist domination of Northern Ireland. The state security forces – the British Army and the police (the Royal Ulster Constabulary) – were also involved in the violence. The British government's point of view is that its forces were neutral in the conflict, trying to uphold law and order in Northern Ireland and the right of the people of Northern Ireland to democratic self-determination. Irish republicans regarded the state forces as "combatants" in the conflict, alleging collusion between the state forces and the loyalist paramilitaries as proof of this (loyalists are against the union of Ireland). The "Ballast" investigation by the Police Ombudsman has confirmed that British forces, and in particular the RUC, did collude with loyalist paramilitaries, were involved in murder, and did obstruct the course of justice when such claims had previously been investigated,[26] although the extent to which such collusion occurred is still hotly disputed.
As a consequence of the worsening security situation, autonomous regional government for Northern Ireland was suspended in 1972. Alongside the violence, there was a political deadlock between the major political parties in Northern Ireland, including those who condemned violence, over the future status of Northern Ireland and the form of government there should be within Northern Ireland. In 1973, Northern Ireland held a referendum to determine if it should remain in the United Kingdom, or be part of a united Ireland. The vote went heavily in favour (98.9%) of maintaining the status quo with approximately 57.5% of the total electorate voting in support, but only 1% of Catholics voted following a boycott organised by the Social Democratic and Labour Party (SDLP).[27]
