Sinn F?in is a unique political party, not only within Irish politics, but also within the wider European context. It boasts a long revolutionary tradition, an historical affiliation with an armed group, a social radicalism and a vision of society that has inspired other parties and movements throughout the world. As a consequence of Sinn F?in's connection with the IRA, the military side of the republican movement has tended to overshadow the political, both in terms of its internal operation and strategic choices and in terms of the attention that it has attracted from scholars, writers and journalists. However, since the 1998 Good Friday Agreement, Sinn F?in has experienced substantial growth, in terms of electoral results and party support, both in Northern Ireland and in the Republic of Ireland. This book assesses the importance and relevance of Sinn F?in within the changing configurations of Irish politics, studying it as a political party on both sides of the Irish border. It investigates whether Sinn F?in can sustain the progress made over the last decade, retain its identity as the voice of radical republicanism, and ultimately, whether its vision of a united Ireland can prevail. Containing interviews with key figures, such as Gerry Adams and Martin McGuinness, New Sinn F?in is essential reading for anyone with an interest in Irish politics, and the republican movement in particular.
