The Kings and Generals animated historical documentary series on the early history of Russia continues with a video on the reign of Oleg, Igor, Olga and Sviatoslav, as the Rurikids consolidate the Kievan Rus, attack the Khazars and the Byzantines. This video covers the struggle with the Drevlians and the religious rites of the Kievan Rus and its Variag masters. And, obviously, another siege of Constantinople.
