Jews and Old Believers are two communities that played a significant role in Russian history and simultaneously experienced repressive pressure from both the Russian Empire and the Soviet Union. Mikhail Kizilov and Grigory Bondarenko's book is one of the first attempts to comprehensively analyze the interfaith and intercultural dialogue between these two groups from the 18th to the 21st centuries. How did Jews convert to the Old Believers? How were mixed marriages conducted? How did Old Believers help Jews escape the Holocaust? And what were the conflicts between these two communities like? The authors find answers to these questions in published and archival written sources, as well as numerous interviews conducted in Jewish and Old Believer communities in the former Russian Empire and the USSR (Russia, Ukraine, Belarus, Moldova, Transnistria, and Latvia). Mikhail Kizilov is a historian, orientalist, and specialist in Jewish history and culture. He holds a PhD in philosophy from Oxford and is a faculty member at the Johannes Gutenberg University of Mainz, Germany. Grigory Bondarenko holds a PhD in history and a Master of Philosophy from Oxford. He is a lecturer at Beijing Capital Normal University, China, and a parishioner of the Tver Old Believer community at the Church of St. Nicholas the Wonderworker in Moscow.
