Joe Cahill (Irish: Seosamh Ó Cathail ; 19 May 1920 – 23 July 2004) was a prominent figure in the Irish Republican movement in Northern Ireland and former chief of staff of the Provisional Irish Republican Army (IRA).
 He joined a junior-republican movement, Na Fianna Eireann, in 1937 and the following year, joined the Irish Republican Army.
 In 1969, Cahill was a key figure in the founding of the Provisional Irish Republican Army.
 During his time in the Provisional IRA, Cahill helped import weapons and raise financial support.
 He served as the chief of staff in 1972, but was arrested the following year when a ship importing weapons was intercepted.
 After his release, he continued to serve on the IRA Army Council and lead all financial dealings for Sinn Féin.
 In the 1990s, the IRA and Sinn Féin began to work on seeking peace.
 Cahill served on the council that called a cessation on 21 July 1996.
 Cahill attended several of the talks that finally led to the Good Friday Agreement on 10 April 1998.
 Shortly after the agreement was made, Cahill resigned as treasurer of Sinn Féin.
 To honour his service, he was made honorary Sinn Féin Vice-President for life.

Patrick Joseph Magee (born 1951) is a former Provisional Irish Republican Army (IRA) Terrorist, best known for planting a bomb in the Brighton's Grand Hotel targeting Prime Minister Margaret Thatcher and her cabinet, which killed two men and three women.

Joanna Cynthia Berry (born 1957) is a British peace activist and public speaker.
 She is the daughter of Hon. Sir Anthony Berry, who was killed by the IRA in the Brighton hotel bombing on 12 October 1984.
 The bomb was planted by Patrick Magee, whom Berry publicly met in November 2000 in an effort at achieving reconciliation as envisioned in the wake of the Good Friday Agreement.
Gerard "Gerry" Kelly (born 5 April 1953) is an Irish republican politician and former Provisional Irish Republican Army (IRA) volunteer who played a leading role in the negotiations that led to the Good Friday Agreement on 10 April 1998.
 He is currently a member of Sinn Féin's Ard Chomhairle (National Executive) and a Member of the Northern Ireland Assembly (MLA) for North Belfast.
Dissident republicans, renegade republicans, anti-Agreement republicans or anti-ceasefire republicans (Irish: "poblachtach easaontach" ) are Irish republicans who do not support the current peace agreements in Northern Ireland.
 The agreements followed a 30-year conflict known as the Troubles, which claimed over 3,500 lives.
 During the conflict, republican paramilitary groups such as the Provisional Irish Republican Army waged a campaign to bring about a united Irish republic.
 Peace negotiations in the 1990s led to an IRA ceasefire in 1994 and to the Good Friday Agreement of 1998.
 Mainstream republicans, represented by Sinn Féin, supported the Agreement as a means of achieving Irish unity peacefully.
 'Dissidents' saw this as an abandonment of republican ideals and acceptance of partition and British rule.
 They hold that the Northern Ireland Assembly and Police Service of Northern Ireland (PSNI) are illegitimate and see the PSNI as a "British paramilitary police force".
The Omagh bombing was a car bombing that took place on 15 August 1998 in Omagh, County Tyrone, Northern Ireland.
 It was carried out by a group calling themselves the Real Irish Republican Army, a Provisional Irish Republican Army (IRA) splinter group who opposed the IRA's ceasefire and the Good Friday Agreement.
 The bombing killed 29 people (including a woman pregnant with twins) as well as injuring some 220 others, a death toll even higher than that of any single incident during what were considered 'the Troubles' (1968-10 April 1998).
 Telephoned warnings had been sent about 40 minutes beforehand, but were claimed to be inaccurate and police had inadvertently moved people towards the bomb.
The Real Irish Republican Army or Real IRA (RIRA), is a dissident Irish republican paramilitary organisation which aims to bring about a united Ireland.
 It formed in 1997 following a split in the Provisional IRA by dissident members, who rejected the IRA's ceasefire that year.
 Like the Provisional IRA before it, the RIRA sees itself as the only rightful successor to the original Irish Republican Army and styles itself as "the Real Irish Republican Army" in English or "Óglaigh na hÉireann" in Irish.
 It is an illegal organisation in the Republic of Ireland and designated as proscribed terrorist organisation in the United Kingdom and the United States.
