Modern Russia’s turbulent relations with its Muslim frontiers date back centuries. Indeed the nineteenth century, when the Muslim Caucasus first came under Russian rule, witnessed many of the historical antecedents to today’s violent confrontations. With this in mind, On The Religious Frontier examines the history of Muslim Azerbaijan under Christian Orthodox Russian imperial rule and the attempts of the Russian administrators of the Caucasus to integrate the region into the empire. Drawing on original archival research from across Azerbaijan and Russia, Firouzeh Mostashari considers the formation of a Russian colonial administration in the Muslim Caucasus; subsequent social, political and economic developments; and the local responses to conquest, military rule and Russification. From 1804 to the Bolshevik Revolution of 1917, On The Religious Frontier offers a fascinating and timely insight into both the period itself and the ways in which the seeds of recent conflict were sown in tsarist Russia. This is important reading for all scholars of the history and politics of the Caucasus, as well as those with an interest in imperial Russia and its relationship with minority groups.
