The reasons behind terrorist attacks in Great Britain are many. During the 20th century, most attacks were carried out by various Irish Republican Army (IRA) groups and were linked to the Northern Ireland conflict (the Troubles). In the late 20th century there were also isolated attacks by Middle Eastern terrorist groups, though the vast majority of the attacks were the work of the IRA and splinter groups. During the 21st century, however, most terrorist incidents in Britain have been linked to Islamic fundamentalism.^[1]

Since 1970, there have been at least 3,395 terrorist-related deaths in the UK, the highest in western Europe.^[2] The vast majority of the deaths were linked to the Northern Ireland conflict and happened in Northern Ireland.^[2] Between 1971 and 2001, there were 430 terrorist-related deaths in Great Britain. Of these, 125 deaths were linked to the Northern Ireland conflict,^[3] and 305 deaths were linked to other causes^[4] – most of the latter deaths occurred in the Lockerbie bombing.^[4]
