The book of the famous Russian writer and historian Valery Shambarov explores one of the most terrible and mysterious figures of the 1917 revolution - Yakov Sverdlov, whose non-mythical personality, as it were, accidentally fell out of sight of domestic scientists. It turns out that the "leader No. 2" of the Great October Revolution, the first president of Soviet Russia, was... occultist. The departure from Orthodox Judaism, caused by a wandering revolutionary life, led him to independently search for some deep "truths." Their entire infernal essence was fully manifested at a turning point in our history, during the years of revolution and civil war. This book is an attempt to objectively assess the life and work of Yakov Sverdlov at the head of the anti-Christian coup of 1917.
