British Army corporals David Howes and Derek Wood were killed by the Provisional IRA on 19 March 1988 in Belfast, Northern Ireland, in an event which became known as the corporals killings.
 The off-duty soldiers were wearing plain-clothes when they were killed by the IRA after encountering the funeral procession of an IRA member whilst returning from Belfast to Lisburn.
 Three days before, loyalist paramilitary Michael Stone had attacked an IRA funeral and killed three people.
 Believing the soldiers were loyalists intent on repeating Stone's attack, dozens of people surrounded and attacked their car.
 During this, Corporal Wood drew his service pistol and fired a shot in the air.
 The soldiers were then dragged from the car, beaten, and taken to nearby waste ground where they were stripped and shot dead.
The Loughgall ambush took place on 8 May 1987 in the village of Loughgall, Northern Ireland.
 An eight-man unit of the Provisional Irish Republican Army (IRA) launched an attack on the Royal Ulster Constabulary (RUC) barracks in the village.
 An IRA member drove a digger with a bomb in its bucket through the perimeter fence, while the rest of the unit arrived in a van and fired on the building.
 The bomb exploded and destroyed almost half of the base.
 Soldiers of the British Army's Special Air Service (SAS) then returned fire from the base and opened fire from hidden ambush positions around it, killing all IRA members.
 The security forces were aware of the IRA plan and the 24-man SAS unit had been lying in wait.
 Two of the IRA members were unarmed.
 A civilian was also killed by the SAS after unwittingly driving into the ambush zone.
Dr. Bridget Rose Dugdale (born 1941 in Honiton, Devon), better known as Rose Dugdale, is a former debutante who rebelled against her wealthy upbringing, becoming a volunteer in the militant Irish republican organisation, the Provisional Irish Republican Army (IRA).
 As an IRA member, she took part in the theft of paintings worth IR£8 million and a bomb attack on a Royal Ulster Constabulary (RUC) station using a hijacked helicopter.
Norman Beresford Tebbit, Baron Tebbit, (born 29 March 1931) is a British politician and life peer.
 A member of the Conservative Party, he served in the Cabinet from 1981 to 1987 as Secretary of State for Employment (1981–83), Secretary of State for Trade and Industry (1983–85), Chancellor of the Duchy of Lancaster (1985–87) and Chairman of the Conservative Party (1985–87).
 He was a member of parliament (MP) from 1970 to 1992, representing the constituencies of Epping (1970–74) and Chingford (1974–92).
The Harrods bombing usually refers to the car bomb that exploded outside Harrods department store in central London on Saturday 17 December 1983.
 Members of the Provisional IRA planted the time bomb and sent a warning 37 minutes before it exploded, but the area was not evacuated.
 The blast killed three police officers and three civilians, injured 90 people, and caused much damage.
 The IRA Army Council claimed it had not authorised the attack and expressed regret for the civilian casualties.
 The IRA had been bombing commercial targets in England since the early 1970s, as part of its "economic war".
 The goal was to damage the economy and cause disruption, which would put pressure on the British government to withdraw from Northern Ireland.
Margaret Elizabeth Tebbit, Lady Tebbit, née Daines, is a former nurse who was severely and permanently paralysed by the IRA's 12 October 1984 bombing of the Grand Hotel in Brighton, where she was staying with her husband, Norman Tebbit, then Secretary of State for Trade and Industry, during the Conservative Party Conference.
Margaret Elizabeth Leigh (29 October 1849 – 22 May 1945), later Margaret Elizabeth Leigh Child-Villiers, Countess of Jersey, was an English noblewoman, activist, writer and hymn-writer.
The Brighton hotel bombing was a Provisional Irish Republican Army (IRA) assassination attempt against the top tier of the British government in 1984 that occurred on 12 October 1984 at the Grand Brighton Hotel in Brighton, England.
 A long-delay time bomb was planted in the hotel by IRA member Patrick Magee, with the purpose of killing Prime Minister Margaret Thatcher and her cabinet, who were staying at the hotel for the Conservative Party conference.
 Although Thatcher narrowly escaped injury, five people were killed including a sitting Conservative MP, and 31 were injured.
Eoin Mcnamee (MacNamee) was a long-time IRA member and former head of its Northern Command.
 McNamee died in August 1986.
 On 11 June 1939, McNamee was charged with being a member of the I.R.A. and sentenced to six months in Crumlin Road Jail, Belfast.
 In April 1942, a new IRA Army Council was elected and McNamee was named Adjutant General.
 During World War II, it is believed that McNamee met with a German agent in Ireland.
 Later in his life, he lived in the Chicago area of the US where he is supposed to have acted as the go-between for the IRA leadership and its weapons suppliers in the U.S.
