It makes me laugh . Genghis Khan don't die by the hand of his daughter in law in Poland he died from burbonic plague in China. The Mongol Empire beat the crap out of polish and hungarian and they reach Wien.in 1241 , 14 years after Geghis Khan died. When his son. Ogotai dies the invasion has stopped, , Poland never be an obstacle in front of.anybody. Stepen of Crakow it's an invented personage , he never existed. Mongols never suffer a defeat like americans never had a win or a neuron .As a fiction movie it's an easy to watch movie with gorgeous Anita Ekberg.and Antonella Lualdi , but has nothing to do with reality like western media nowdays.
