Book excerpt: Irish Political Prisoners presents a detailed and gripping overview of political imprisonment from 1920-1962. Seán McConville examines the years from the formation of the Northern Ireland state to the release of the last border campaign prisoners in 1962. Drawing extensively and, in many cases, uniquely on archives and special collections in the three jurisdictions, and interviews with survivors from the period, McConville demonstrates how punishment came to embody and shape the nationalist consciousness. Irish Political Prisoners 1920-1962 commences with the legacy of the Anglo Irish and Irish Civil Wars - militancy, division and bitterness. The book travels from the embedding of Northern Ireland’s security agenda in the 1920’s, and the IRA’s search for a role in the 1930’s (including the 1939 bombing campaign against Britain) to the decisive use of internment during the war and the border campaign years. This volume will be an essential resource for students of Irish history and is a major contribution to the study of imprisonment. .
