Helena Molony was one of the most fascinating activists in twentieth-century Irish history. She was one of the most important female activists of the Irish revolutionary era, yet she has never been the subject of a major biographical study until now. This first biography sheds light not only on Molony, but on the many causes and characters she worked with during her long public career. It charts her life as a campaigning journalist, an Abbey actress, one of James Connolly’s closest confidantes in the Irish Citizen Army during the period leading up to the Easter Rising, and her time as general secretary of the Irish Women Workers’ Union during the crucial period after 1916 when it almost collapsed. She would go on to campaign for workers and women’s rights in an increasingly conservative society that was intolerant of dissent. Her refusal to conform to the social, sexual or economic mores of her day took a heavy toll on her health and later career.
