Is there some higher meaning in the emergence of Genghis Khan's empire? Or did a monstrous game of chance bring countless kingdoms of Asia and Europe to the feet of the Mongol warrior, destroying their inhabitants? A definitive answer to these questions is unlikely. The author of the book you are holding in your hands, Erenzhen Khara-Davan, a historian of the Eurasian type, a Kalmyk by nationality, did not follow the path of unrestrained national apologetics. First of all, he seeks to comprehend the essence of the very idea of the Eurasian empire. The reader will probably not agree with all of his conclusions. However, this book gives rise to very non-trivial thoughts. And more interesting than textbook Eurasianism.
