Book excerpt: This book examines how religion interacts with Russian foreign policy, arguing that religion is an important and neglected factor in shaping Russia’s outlook towards international relations. It surveys the importance of religion for social life in Russia, both historically and at present, and considers a wide range of Russian attitudes which are affected by religion – such as Russian nationalism, notions of Slavic solidarity, the divine mission of Russian Orthodox civilisation, Russian imperialism, Russia’s special approach towards Islam. The book discusses how religious organizations, especially the Russian Orthodox Church, operate in international relations, pursuing their own interests and those of the Russian state; explores how religious ideas and culture linked to religion impinge on Russian attitudes and identity, and thereby affect policy; and demonstrates how policy influenced by religion impacts on Russian foreign policy in practice in a wide range of examples, including Russia’s relations with other orthodox countries, non-orthodox Western countries, Muslim countries, Israel and the Vatican.
