terrorism by country of irsh republic army

United Kingdom

 England

The early modern period in Britain saw religious conflict resulting from the Reformation and the introduction of Protestant state churches.^[4] The Gunpowder Plot was a failed attempt to blow up the Palace of Westminster, the English seat of government. Peter Steinfels characterizes this plot as a notable case of religious terrorism.

The Irish Republican Army regarded bombing English targets as militarily and symbolic. They were responsible for attacks in England over decades, starting in 1939, and then a new campaign commenced after Bloody Sunday in 1972.

Northern Ireland

                        Some scholars, such as Steve Bruce, a sociology professor at the University of Aberdeen, argue that the conflict in Northern Ireland is primarily a religious conflict, its economic and social considerations notwithstanding. Professor Mark Juergensmeyer has also argued that some acts of terrorism were "religious terrorism... - in these cases, Christianity". Others, such as John Hickey, take a more guarded view. Writing in The Guardian, Susan McKay discussed religious fundamentalism in connection with the murder of Martin O'Hagan, a former inmate of the Maze prison and a reporter on crime and the paramilitaries. She attributed the murder to a "range of reasons," including "the gangsters didn't like what he wrote". The alleged killers claimed that they killed him for "crimes against the loyalist people".

The Orange Volunteers are a group infamous for carrying out simultaneous terrorist attacks on Catholic churches

In 1999 Pastor Clifford Peeplesof the Bethel Pentecostal Church was convicted of offences under the Prevention of Terrorism Act and sentenced to ten years imprisonment after being found in possession of hand grenades and a pipe bomb intended for use against Catholics. Pastor John Somerville, an associate of Peeples, had previously been convicted under the Prevention of Terrorism Act and had received a life sentence for his part in the Miami Showband massacre. RUC chief constable, Ronnie Flanagan dubbed Peeples and his associates "the demon pastors" – specialising in recounting lurid stories of Catholic savagery towards Protestants, and in finding biblical justifications for Protestant retaliation.^[10] Other notable individuals convicted for terrorism offences include Pastor Kenny McClinton, a convicted murderer who once advocated beheading Roman Catholics and impaling their heads on railings, and Billy Wright, a Born again Christian preacher who became one of the most feared paramilitary figures in Northern Ireland before being assassinated whilst incarcerated in prison.
