Early twentieth-century Persia and the Persian Gulf presented a largely blank slate to the British, best known only as a vital conduit to India and a site of contest – the 'great game' – with the Russian Empire. As oil discoveries and increasing trade brought new attention, the expanding telegraph and river shipping industries attracted resourceful men into junior positions in remote outposts. Love, Class and Empire explores the experiences of two of these men and their families. Drawing on a wealth of personal letters and diaries, A. James Hammerton examines the complexities of expatriate life in Iran and Iraq, in particular the impact of rapid social mobility on ordinary Britons and their families in the late imperial era. Uniquely, the study blends histories of empire with histories of marriage and family, closely exploring the nature of expatriate love and sexuality. In the process, Hammerton discloses a tender expatriate love story and offers a moving account of transient life in a corner of the informal empire.
