Book excerpt: This book provides a scholarly yet accessible account of the Irish nationalist youth organisation Na Fianna Éireann and its contribution to the Irish Revolution in the period 1909–23. Countess Constance Markievicz and Bulmer Hobson established Na Fianna Éireann, or the Irish National Boy Scouts, as an Irish nationalist antidote to Robert Baden-Powell’s scouting movement founded in 1908. Between their establishment in 1909 and near decimation during the Irish Civil War of 1922–23, Na Fianna Éireann recruited, trained and nurtured a cadre of young nationalist activists who made an essential contribution to the struggle for Irish independence. This book will be of interest to historians and students specialising in the history of the Irish Revolution, youth culture, paramilitarism and twentieth-century Ireland. It will also appeal to the general reader with an interest in the history of the Irish Revolution.
