The February Revolution of 1917 - a dark period in Russian history - is practically unknown to the mass reader. Yana Sedova’s book “The Grand Master of the Revolution” destroys existing stereotypes and convincingly proves that it is not the “Jews and Freemasons” who are most to blame for the overthrow of the Russian autocracy, but the monarchists themselves, and above all the leader of the Russian monarchist movement, Guchkov, who, due to his hypertrophied pride, destroyed the thousand-year-old monarchy. The book is written on the basis of archival materials and will be of interest to teachers, students and anyone interested in Russian history.
