The Troubles consisted of about 30 years of repeated acts of intense violence between elements of Northern Ireland's Nationalist community (principally Roman Catholic) and Unionist community (principally Protestant). The conflict was caused by the disputed status of Northern Ireland within the United Kingdom, and the alleged domination of the minority nationalist community, and discrimination against, by the unionist majority. The violence was characterised by the armed campaigns of paramilitary groups. Most notable of these was the Provisional IRA campaign 1969--1997 which was aimed at the end of British rule in Northern Ireland and the creation of a new all-Ireland Irish Republic. In response to this campaign and the perceived erosion of the British character and unionist domination of Northern Ireland, loyalist paramilitaries such as the UVF and UDA launched their own campaigns against the nationalist population. The state security forces - the British Army and the police (the Royal Ulster Constabulary) - were also involved in the violence. The British government point of view is that its forces were neutral in the conflict and trying to uphold law and order in the North. Irish republicans, however, regarded the state forces as "combatants" in the conflict and point to evidence of repeated collusion between the state forces and the loyalists as proof of this.
