Dramatic and tragic rescues of arrested Fenian leaders, the formation of a Fenian squad to engage in assassinations of suspected informers and policemen, the bombing of a London prison that brought death and destruction to a neighbouring street, public executions of several Fenians, the quality of British justice, and the struggle to develop counter-terrorism policies and an effective system of intelligence form the core of The Fenian Problem . Brian Jenkins adds new information to the established narrative of the movement, arguing that it resorted to terrorism in its pursuit of Irish independence. Jenkins discusses both the parallels between the government's treatment of Fenian prisoners in the 1860s and their handling of the IRA in the 1970S and the similarities between the challenges posed by Fenians and those presented by Islamic insurgents, showing that nineteenth-century British and Irish history illuminate contemporary discussions of state security and liberal government responses to terrorism. Brian Jenkins is emeritus professor of history, Bishop's University, and the author of numerous books, including Era of Emancipation and Irish Nationalism and the British State.
