The Islamic Threat to the Soviet State (Routledge Revivals) [EPUB ebook] 

First published in 1983, this book traces the historical and cultural development of the Soviet Muslim population. Going back to the Mongol Empire and the Russian conquest of Muslim lands under the Tsars, it demonstrates how the present Soviet Islamic culture has emerged. It also examines how Soviet Muslims interact with the Muslim world abroad and how Soviet Muftis have been used as ambassadors of the USSR in Muslim countries.
