Resurrection Man is a 1998 British film, directed by Marc Evans with a screenplay written by Eoin McNamee based on his novel of the same name.
 The story is loosely based on the real-life "Shankill Butchers", an Ulster loyalist gang in 1970s Belfast who conducted random killings of Catholic civilians until their leader, Lenny Murphy, was assassinated by a Provisional IRA hit squad.
During the Troubles in Northern Ireland, a total of 14 people were killed in Troubles-related violence in or near the village of Maghera, County Londonderry.
 Of the 13 from Northern Ireland, 11 were Protestant and two were Catholic.
 Seven of the Protestant victims were members of the security forces (six Ulster Defence Regiment (UDR), two Royal Ulster Constabulary (RUC), one British Army) and another was the ten-year-old daughter of a UDR man, killed along with her father by a bomb planted in his car.
 Another victim was shot after being mistaken for his co-worker, an UDR member.
 Only three of the security force victims were killed while on-duty.
 Both the RUC men were killed by the Irish National Liberation Army; all the other Protestant victims were killed by the Provisional Irish Republican Army.
 Both the Catholic victims were killed by loyalist paramilitaries, one by the Ulster Volunteer Force and one by the Loyalist Volunteer Force.
 One was a Sinn Féin councillor.
The Shankill Butchers was an Ulster loyalist gang—many of whom were members of the Ulster Volunteer Force (UVF)—that was active between 1975 and 1982 in Belfast, Northern Ireland.
 It was based in the Shankill area and was responsible for the deaths of at least 23 people, most of whom were killed in sectarian attacks.
 The gang was notorious for kidnapping and murdering random Catholic and suspected Catholic civilians; each was beaten ferociously and had his throat hacked with a butcher's knife.
 Some were also tortured and attacked with a hatchet.
 The gang also killed six Ulster Protestants over personal disputes, and two other Protestants mistaken for Catholics.
 Most of the gang were eventually caught and, in February 1979, received the longest combined prison sentences in United Kingdom legal history.
 However, gang leader Lenny Murphy and his two chief "lieutenants" escaped prosecution.
 Murphy was killed in November 1982 by the Provisional IRA, likely acting with loyalist paramilitaries who perceived him as a threat.
 The Butchers brought a new level of paramilitary violence to a country already hardened by death and destruction.
 The judge who oversaw the 1979 trial described their crimes as "a lasting monument to blind sectarian bigotry".
The Loyalist Volunteer Force (LVF) is a small Ulster loyalist paramilitary group in Northern Ireland.
 It was formed by Billy Wright in 1996 when he and his unit split from the Ulster Volunteer Force (UVF) after breaking its ceasefire.
 They had belonged to the UVF's Mid-Ulster Brigade and Wright had been the brigade's commander.
 In a two-year period from August 1996, the LVF waged a paramilitary campaign with the stated goal of combatting Irish republicanism.
 During this time it killed at least 14 people in gun and bomb attacks.
 Almost all of its victims were Catholic civilians who were killed at random.
 The LVF called off its campaign in August 1998 and decommissioned some of its weapons, but in the early 2000s a loyalist feud led to a number of killings.
 Since then, the LVF has been largely inactive, but its members are believed to have been involved in rioting and organized crime.
 In 2015, the security forces stated that the LVF "exists only as a criminal group" in Mid-Ulster and Antrim.
John Oliver Weir (born 1950) is an Ulster loyalist born in the Republic of Ireland.
 He served as an officer in Northern Ireland's Royal Ulster Constabulary's (RUC) Special Patrol Group (SPG) (a tactical reserve unit), and was a volunteer in the illegal Ulster Volunteer Force (UVF).
 As a member of the UVF's Mid-Ulster Brigade led by Robin "the Jackal" Jackson, Weir was a part of the Glenanne gang, a group of loyalist extremists that carried out sectarian attacks mainly in the County Armagh area in the mid-1970s.
 Along with his RUC colleague Billy McCaughey, Weir was convicted of the 1977 sectarian killing of Catholic chemist William Strathern and sentenced to life imprisonment.
 Weir's affidavit which implicated Jackson, other members of the Glenanne gang, soldiers of the Ulster Defence Regiment (UDR), and his colleagues in the RUC and SPG, in a series of sectarian attacks, including the Dublin and Monaghan bombings, was published in the 2003 Barron Report, the findings of an official investigation into the 1974 car bombings commissioned by Irish Supreme Court Justice Henry Barron.
On 19 December 1975, two coordinated attacks were carried out by the Ulster Volunteer Force (UVF) in pubs either side of the Irish border.
 The first attack, a car bombing took place outside Kay's Tavern, a pub in Dundalk in the Republic of Ireland close to the border.
 The second attack, a gun and bomb attack, took place at Donnelly's Bar & Filling Station in Silverbridge, County Armagh just across the border inside Northern Ireland.
 The attack has been linked to the Glenanne gang, a group of Loyalist militants who were either members of the UVF, the Ulster Defence Regiment (UDR), the Royal Ulster Constabulary (RUC) and the closely linked UVF paramilitary the Red Hand Commando (RHC), some of the Glenanne gang were members of the two of these organizations at the same time like gang leaders Billy Hanna who was in both the UVF and the UDR and who fought for the British Army during the Korean War and John Weir (loyalist) who was in the UVF and was a Sergeant in the RUC.
 At least 25 British soldiers and police officers were named as members of the gang.
William Moore, often known as Billy Moore (1949 – 17 May 2009), was an Ulster loyalist from Belfast, Northern Ireland.
 He was a member of the Shankill Butchers, an Ulster Volunteer Force (UVF) gang.
 It was Moore who provided the black taxi and butcher knives which the gang used to carry out its killings.
 Following ringleader Lenny Murphy's arrest, Moore took over as the "de facto" leader of the gang and the killings continued.
James Mitchell (1920 – May 2008) was an Ulster loyalist and Royal Ulster Constabulary (RUC) Reserve officer who provided a base and storage depot for the Glenanne gang at his farm at Glenanne, near Mountnorris, County Armagh, during the Troubles.
 The gang, which contained over 40 known members, included soldiers of the British Army's Ulster Defence Regiment (UDR), officers of the RUC, the Mid-Ulster Brigade of the illegal paramilitary Ulster Volunteer Force (UVF) and some Ulster Defence Association (UDA) members.
Thomas English (1960 – 31 October 2000), usually known as Tommy English, was an Ulster loyalist paramilitary and politician.
 He served as a commander in the Ulster Defence Association (UDA) and was killed by members of the Ulster Volunteer Force (UVF) as part of a violent loyalist feud between the two organisations.
 English had also been noted as a leading figure in the Ulster Democratic Party (UDP) during the early years of the Northern Ireland peace process.
Clifford Peeples (sometimes spelled Clifford Peoples) (born c.1970) is a self-styled pastor in Northern Ireland who has been associated with Ulster loyalist activity.
 Peeples has been a member of the Ulster Volunteer Force (UVF), the Loyalist Volunteer Force (LVF) prisoners' spokesman and leader of the Orange Volunteers.
