Sinn Fein is a growing force in Irish politics. Now the country's third largest party, Sinn Fein have been one of the central architects of the peace process and are increasingly setting the terms of political debate in Ireland north and south. Despite this, the party remains much misunderstood and often misrepresented. Sinn Fein and The Politics of Left Republicanism explores the ideological and organisational origins of the party, charts their history and recent political development and assesses their possible futures. Eoin O Broin argues that Sinn Fein is part of a distinct left-republican tradition in Irish society whose future lies in the globally resurgent radical democratic left.
