Newspapers, magazines and pamphlets have always been central, almost sacred, forms of communication within Irish republican political culture. While social media is becoming the central ideological battleground in many democracies, Irish republicanism steadfastly expresses itself in the traditional forms of activist journalism. Shinners, Dissos and Dissenters is a long-term analysis of the development of Irish republican activist media since 1998 and the tumultuous years following the end of the Troubles. It is the first in-depth analysis of the newspapers, magazines and online spaces in which the differing strands of Irish republicanism developed and were articulated during a period where schism and dissent defined a return to violence. Based on an analysis of Irish republican media outlets as well as interviews with the key activists that produced them, this book provides a compelling long-term snapshot of a political ideology in transition. It reveals how Irish Republicanism was moulded by the twin forces of the Northern Ireland Peace Process and the violent internal ideological schism that threatened a return to the 'bad old days' of the Troubles. This book is vital for those studying Irish politics and those interested in activism as it provides new insights into the role that modern activist media forms have played in the ideological development of a 200-year-old political tradition.
