About the book: 2017 / Efim Fedorovich Grekulov, a famous historian, writes in his book about the union of church and state in Russia. The reader will be presented with such familiar historical characters as Prince Vladimir, the baptist of Rus', the monk Philotheus, who created the theory of “Moscow is the third Rome”, Ivan the Terrible, the “Orthodox Tsar”, Patriarch Nikon, who carried out his famous reform, Peter I, who abolished the patriarchate in Russia and Nicholas I, who completely subordinated the church to the state, under whom the ideology of “Orthodoxy, autocracy, nationality” was established. At the same time, the book examines how this union of secular and spiritual power affected the position of the people, as well as popular movements against the church. Finally, it also shows the position of the educated strata of Russian society, the difficult relations of M.V. Lomonosov, A.S. Pushkin and other prominent representatives of the Russian intelligentsia with the church authorities.
