The book presents a look at Russian history through the prism of the Russian religious schism. The upheavals that occurred in Russia and caused by church reforms of the mid-17th century had a great impact on the development of the country in the next two centuries. The polysyllabic processes that took place then left an imprint on the entire social fabric of Russian society. It is in confessional originality that the origins of the key events of our history related to the collapse of the Russian Empire in its Niconian form at the beginning of the 20th century lie.
