Nationalist terrorism is linked to a national, ethnic, religious, or other identifying group, and the feeling among members of that group that they are oppressed or denied rights, especially rights accorded to others.
As with the concept of terrorism itself, the term "nationalist terrorism" and its application are highly contentious issues. What constitutes an illegitimate regime and what types of violence and war are acceptable against such a state are subjects of debate. Groups described by some as "nationalist terrorists" tend to consider themselves "freedom fighters", engaged in valid but asymmetric warfare.
Other nationalist terrorism can include violence against immigrants in a country. Nationalists in many countries see immigration as a threat to the prosperity of the local or native population of that country.
Official IRA (1969–72) Although formally on ceasefire, except for "defensive actions", since 1972. The Official IRA continued some attacks on British forces up to mid 1973, killing seven British soldiers in what it termed "retaliatory attacks". No longer an active organization.
Provisional Irish Republican Army (PIRA) (1969–2005). It is currently on ceasefire and has destroyed most of its weaponry. Ihe Independent Monitoring Commission (IMC), in its latest report, dated April 2006, points out that it has no reason to disbelieve the PIRA or information to suspect that the group has not fully decommissioned. Rather it indicated that any weaponry that had not been handed in had been retained by individuals outside the PIRA's control. It was a splinter group of the Official IRA. Supporters of the PIRA split from Official Sinn Féin to form Provisional Sinn Féin. Provisional Sinn Féin was later known simply as Sinn Féin while 'Official' Sinn Féin eventually became the Democratic Left.
Continuity Irish Republican Army (CIRA) (1986–present). Also known as the "Continuity Army Council" and "Óglaigh na hÉireann (Irish for 'Volunteers of Ireland'). It is not on ceasefire.
Real Irish Republican Army (RIRA) (1997–present). Also known as the True IRA and Óglaigh na hÉireann (Irish for Volunteers of Ireland). It is not on ceasefire.
The other community is overwhelmingly Protestant and are known as unionists or loyalists and are largely descended from Scottish and English settlers who arrived in Ulster during the Plantations of Ireland. This community, which forms a slight majority in Northern Ireland, regards itself as essentially British. Paramilitary groups associated with this ideology have received clandestine assistance from the British security forces in the past. Many of their victims have been civilian Catholics with no political connections. These paramilitary groups include:
Ulster Volunteer Force (1966–present). Officially on ceasefire, although the Northern Ireland Secretary Peter Hain announced that the British government no longer recognized the UVF ceasefire after serious loyalist rioting in 2005. UVF renounced "violence" and declared it was putting its arms "beyond reach" on 3 May 2007. The Red Hand Commando is a cover name for UVF.
Loyalist Volunteer Force (1996–2005). The LVF announced in October 2005 that it was standing down following the IRA's previous standing down and disarmament. The Independent Monitoring Commission confirms that the LVF is keeping its paramilitary ceasefire, is heavily involved in organized crime and drug trafficking.
Ulster Defence Association (UDA) (1971–present). Formed as an umbrella organisation of loyalist groups. Legal in the United Kingdom until 1992. Often used the name "Ulster Freedom Fighters" (UFF) when it wished to claim responsibility for attacks. On February 22, 2003, they announced a "complete and utter cessation" of all acts of violence for one year. It said it will review its ceasefire every three months, in February 2006, the Independent Monitoring Commission reported that the UDA continued its paramilitary activities, as well as involvement in organized crime, drug trafficking, counterfeiting, extortion, money laundering and robbery. On 11 November 2007, the UDA formally renounced violence, but a commander said the group would not surrender its weapons to international disarmament officials.
Orange Volunteers (1998–present) The group has not been active since 2000, when they declared a ceasefire. However, in February 2001, the group called off its ceasefire with a "Back to War" statement, but has not been thought to be active since then.
