Sinn Féin is one of the oldest and most controversial parties in Irish politics. This is the fascinating story of a party which has repeatedly reshaped its identity over a hundred years. From Arthur Griffith to Gerry Adams, Sinn Féin boasts a roll-call of major personalities from twentieth-century Irish history including de Valera, Markievicz, Collins, Ó Brádaigh, Goulding, MacGiolla, and McGuinness. Brian Feeney traces Sinn Féin's zigzag path towards constitutional politics and presents a critical analysis of the party's personalities and policies over the century. He shows how it has arrived at last in government in the north with hopes of a future role in coalition in the republic, and confidently predicting a united Ireland. This is an important and timely book from an esteemed journalist, and an impartial analysis of Sinn Féin's involvement in Irish politics, north and south, over the last hundred years.
