As a political agitator, journalist, businessman and politician, Hugh Mahon had a varied and fascinating life. Born in Offaly, he and his family migrated to America in 1869, but returned to Ireland in 1880 after their American dream failed. He was active in the Land League in County Wexford which led to his arrest, imprisonment with Parnell in 1881, and exile to Australia. As a crusading journalist he exposed corruption and became a thorn in the side of the Forrest government in Western Australia during the 1890s. He was elected to the first Commonwealth parliament in 1901 and served in four Labor ministries, rising to Minister for External Affairs during the First World War. He has the distinction of being the only person expelled from the Commonwealth parliament. This book pulls together the many facets of Mahon's life to reveal the forces which drove this complex man, who was reviled by many for denouncing the British Empire, while remaining a hero to those who supported Home Rule for Ireland.
