A people unable to protect its past loses its future. It is no coincidence that the collapse of the USSR began with the denigration of Russian history. Many national shrines were trampled, national heroes were slandered. Lies even infiltrated school and university textbooks. The Holy Blessed Prince Alexander Nevsky did not escape her either. Was Alexander Yaroslavich the first "traitor-collaborator" in Russia, as some historians claim? Is it true that he "trampled on Russian freedom" by entering into a "criminal conspiracy with Batu" and embarking on the path of "shameful submission to the Asian conquerors"? Natalia Pronina convincingly proves that all these accusations are completely false. On the pages of her book, in all the greatness of his feat, a great warrior and a martyr humble before God for Russia appears, calling for Struggle and Sacrifice, which Prince Alexander was all his short life and which remained forever in the memory of the Russian people.
