Love dramas of Russian princesses. From Catherine I to Nicholas II (16+)

Empress Catherine the Great in one of the letters to her constant correspondent to Baron Grimm expressed this way: ... nothing can be more unhappy of the Russian Grand Duchess.
This remark turned out to be prophetic, because in very rare cases, the Russian Grand Duchesses were happy in marriage. Indeed, the princesses or princesses could not decide their fate, they could not trust anyone. Any manifestation of sympathy for them could be insincere. In their family life, even if true love arose in it, there was a lot of ostentatious and deliberate.
The book tells about the sad fate of the great princes of the daughters of the emperors Paul I, Nicholas I, Alexander II and Alexander III
