Who organized the assassination attempt on Nicholas II during his trip to the East? Is it true that Emperor Alexander III was poisoned? Who was the real culprit of the tragedy on the Khodynskoye Field? Why were members of the Royal Family unable to leave Russia after the revolution and save their lives? Various episodes from the life of the Imperial House of Romanov have become overgrown with myths in books and films and differ significantly from reality. For the first time, the reader received a rare opportunity to get an idea of the secrets of the Romanov dynasty and the real events of the late 19th - early 20th centuries. Most of the materials presented in this publication were in “special storage” for a long time, many of them are unknown not only to a wide circle of readers, but also professional historians.
