Monitoring the Peace?: Northern Ireland's 1975 Ceasefire Incident Centres and the Politicisation of Sinn Féin

During the Provisional IRA's (PIRA) 1975 ceasefire, two different sets of incident centres were established across Northern Ireland in order to monitor and avert escalation of violence between Republicans and Security Forces. While one group of offices was run by the Northern Ireland Office (NIO) and administered by clerks in the Northern Ireland Civil Service, very quickly Sinn Féin (taking advantage of their decriminalisation in 1974) established their own incident centres to coordinate their communication with the government. This article argues that the establishment of the Sinn Féin incident centres set a precedent for the future political activity of the Provisional Republican Movement; that their activity during the 1975 ceasefire played an important formative role in the evolution of the group's political strategy; and that this experience, acquired from the work done during the 1975 truce, was of far greater influence than is appreciated in current accounts.
