At the height of her imperial power Britain clashed with Russia at many points from Turkey to China. But it was only in Persia and Central Asia that these two expansionist empires met face to face. The fear of a Russian drive against India had initially impelled the British to oppose the extension of Russian influence. Russia's subsequent advance into Central Asia and her spectacular conquests in the second half of the nineteenth century both startled Europe and narrowed the gap separating the Russians and the British. This classic work by distinguished historian Firuz Kazemzadeh provides an outstanding history of Anglo-Russian relations in Persia in the half century preceding the First World War. It affords both a comprehensive overview of British and Russian policy in Iran and detailed coverage of the most important events. The new introduction includes reflections upon of events after the First World War. Long unavailable this new edition will be welcomed by scholars and students alike and provides a fascinating backdrop to the motivations behind Iran's diplomatic posture today. Firuz Kazemzadeh is Emeritus Professor of History at Yale University. He has taught at Harvard and Yale universities and was subsequently appointed Commissioner to the United States Commission on International Religious Freedom by President Clinton. As well as Russia and Britain in Persia Professor Kazemzadeh is the author of The Struggle for Transcaucasia.
