Fully Revised and Enlarged Edition with a new ForewordSince his execution for high treason in 1916, Roger Casement has been lauded for his humanitarian activism in Africa and the Amazon. His life, however, has remained obscured behind speculation about his sexuality and his complicated contribution to Ireland’s revolutionary generation that took up arms against the British Empire. He lives on as an enduring enigma in the history of British-Irish relations—a figure who refuses easy categorisation, and whose legacy demands radical reconsideration. Angus Mitchell traces the life of a man fatally divided between serving the empire and advancing demands for an independent Irish nation. Understanding his logical evolution from imperialist to revolutionary unmasks a coherent global dimension to the Irish struggle. The apparent contradictions of his life resolve into a singular commitment to humanity, justice, and universal principles of love and tolerance. Beyond what it tells us about Casement’s fated path to the scaffold in Pentonville Prison, this biography invites readers to question the curation of national history,  the hidden power of archives, and the lasting impact of state secrecy.
