The timescale covers events in the years prior to Bloody Sunday, and subsequent events up to and including the Widgery Tribunal.

Bloody Sunday (film): Bloody Sunday is a 2002 film about the 1972 "Bloody Sunday" shootings in Derry, Northern Ireland.  Although produced by Granada Television as a TV film, it premiered at the Sundance Film Festival on 16 January, a few days before its screening on ITV on 20 January, and then in selected London cinemas from 25 January.  The production was written and directed by Paul Greengrass.  Though set in Derry, the film was actually shot in Ballymun in North Dublin.

Bloody Sunday: Scenes from the Saville Inquiry: Bloody Sunday: Scenes from the Saville Inquiry is a 2005 dramatisation by English journalist Richard Norton-Taylor of four years of evidence of the Saville Inquiry, distilled into two hours of stage performance by Tricycle Theatre in London.

Sunday Bloody Sunday: "Sunday Bloody Sunday" is a song by Irish rock band U2.  It is the opening track from their 1983 album "War" and was released as the album's third single on 11 March 1983 in Germany and the Netherlands.  "Sunday Bloody Sunday" is noted for its militaristic drumbeat, harsh guitar, and melodic harmonies.  One of U2's most overtly political songs, its lyrics describe the horror felt by an observer of the Troubles in Northern Ireland, mainly focusing on the Bloody Sunday incident in Derry where British troops shot and killed unarmed civil rights protesters and bystanders.  At the same time, the lyrics reject hate and revenge as a response, as noted in the line "There's many lost, but tell me who has won."  Along with "New Year's Day," the song helped U2 reach a wider listening audience.  It was generally well received by critics on the album's release.

Bloody Sunday Inquiry: The Bloody Sunday Inquiry, also known as the Saville Inquiry or the Saville Report after its chairman, Lord Saville of Newdigate, was established in 1998 by British Prime Minister Tony Blair after campaigns for a second inquiry by families of those killed and injured in Derry on Bloody Sunday during the peak of ethno-political violence known as The Troubles.  It was published on 15 June 2010.  The inquiry was set up to establish a definitive version of the events of Sunday 30 January 1972, superseding the tribunal set up under Lord Widgery that had reported on 19 April 1972, 11 weeks after the events, and to resolve the accusations of a whitewash that had surrounded it.

Riot control: Riot control refers to the measures used by police, military, or other security forces to control, disperse, and arrest people who are involved in a riot, demonstration, or protest.  If a riot is spontaneous and irrational, actions which cause people to stop and think for a moment (e.g. loud noises or issuing instructions in a calm tone) can be enough to stop it.  However, these methods usually fail when there is severe anger with a legitimate cause, or the riot was planned or organized.  Law enforcement officers or military personnel have long used less lethal weapons such as batons and whips to disperse crowds and detain rioters.  Since the 1980s, riot control officers have also used tear gas, pepper spray, rubber bullets, and electric tasers.  In some cases, riot squads may also use Long Range Acoustic Devices, water cannons, armoured fighting vehicles, aerial surveillance, police dogs or mounted police on horses.  Officers performing riot control typically wear protective equipment such as riot helmets, face visors, body armor (vests, neck protectors, knee pads, etc.), gas masks and riot shields. However, there are also cases where lethal weapons are used to violently suppress a protest or riot, as in the Boston Massacre, Haymarket Massacre, Banana Massacre, Hungarian Revolution of 1956, Kent State Massacre, Soweto Uprising, Mendiola Massacre, Bloody Sunday (1905) and Bloody Sunday (1972).

Bloody Sunday (1972): Bloody Sunday – sometimes called the Bogside Massacre – was an incident on 30 January 1972 in the Bogside area of Derry, Northern Ireland, when British soldiers shot 28 unarmed civilians during a peaceful protest march against internment.  Fourteen people died: thirteen were killed outright, while the death of another man four months later was attributed to his injuries.  Many of the victims were shot while fleeing from the soldiers and some were shot while trying to help the wounded.  Other protesters were injured by rubber bullets or batons, and two were run down by army vehicles.  The march had been organised by the Northern Ireland Civil Rights Association (NICRA).  The soldiers involved were members of the 1st Battalion, Parachute Regiment, also known as "1 Para".

Don Mullan: Don Mullan (born 1956, Derry, Northern Ireland) is an Irish best-selling author/humanitarian and media producer.  His book "Eyewitness Bloody Sunday" is officially recognised as a primary catalyst for a new Bloody Sunday Inquiry which became the longest-running and most expensive in British Legal History.  Mullan, who is dyslexic, has spoken widely and was co-producer of a highly acclaimed and multi-award winning film about Bloody Sunday that was inspired by his book.

Bloody Sunday (1921): Bloody Sunday or Belfast's Bloody Sunday was a day of violence in Belfast, Ireland (present-day Northern Ireland) on 10 July 1921, during the Irish War of Independence.  In retaliation for an Irish Republican Army (IRA) ambush of a police raiding party, Protestant loyalists attacked Catholic enclaves, burning homes and businesses.  This sparked gun battles between republican and loyalist paramilitaries, and street fighting between Catholics and Protestants.  There was also shooting between republicans and police, and it is claimed that some police patrols fired indiscriminately at Catholic civilians.  Seventeen people were killed on 10 July, and a further eleven were killed or fatally wounded over the following week.  At least 100 people were injured.  About 200 houses were badly damaged or destroyed, leaving 1,000 people homeless.  The violence took place just before a truce came into effect, which ended the war in most of Ireland.

Volhynian Bloody Sunday (1943-07-11): On Sunday July 11, 1943, the OUN-UPA death squads aided by the local Ukrainian peasants simultaneously attacked at least 99 Polish settlements within the Wołyń Voivodeship of the prewar Second Polish Republic under the German occupation.  It was a well-orchestrated attack on people gathered for a Sunday mass at Catholic churches.The towns affected included Kisielin (Kisielin massacre), Poryck (Poryck Massacre), Chrynów (Chrynów massacre), Zabłoćce, Krymn, with dozens of other towns attacked at different dates with tens of churches and chapels burned to the ground.  The Volhynian massacres spread over four prewar voivodeships including Wołyń with 60,000 victims, as well as Lwów, Stanisławów and Tarnopol in Lesser Poland with 70,000 Poles murdered for the total of 130,000 Polish victims of UPA terror.  The Bloody Sunday of July 11, 1943, is not to be confused with the Stanisławów Ghetto Bloody Sunday massacre of 10,000 to 12,000 Polish Jews on October 12, 1941, before the Stanisławów Ghetto announcement. <ref name="Eisen/Stark"> </ref>
