This biography reveals the full significance of Robert Briscoes influence within the contentious political culture of the early Irish state, as well as reinforcing his importance to the global Zionist rescue effort of the 1930s. Drawing on a wealth of previously unavailable archival material, the book charts Briscoes evolution from a fringe Sinn Féin activist in 1917 to a member of Michael Collinss personal staff in 1921. It also analyses his agonizing decision to abandon Collins and support the anti-Treaty stance of his close friend and political hero, Éamon de Valera, before becoming a founding member of Fianna Fįil in 1926. Most importantly of all, the book investigates Briscoes evolving Jewish awareness, looking at his involvement in a traumatic immigration endeavour and also at his engagement with Zeev Jabotinsky and the New Zionist Organisation, under whose auspices he led political rescue missions to Poland, America and South Africa.
