The book by the famous Russian writer Valery Shambarov examines one of the most terrible and mysterious figures of the 1917 revolution, Yakov Sverdlov, whose non-mythical personality seemed to accidentally fall out of sight of domestic historians. It turns out that “Leader No. 2” of the Great October Revolution, the first president of Soviet Russia, was... an occultist. The departure from Orthodox Judaism, caused by a wandering revolutionary life, led him to an independent search for certain deep “truths.” Their entire infernal essence fully manifested itself at a turning point in our history, during the years of the revolution and the Civil War, whose anti-Christian character is now obvious.
