Genghis and his sons are a very interesting period of history.
The Mongols got some bad press i think, as from Europes point of view they were the barbarians.
In actuality the mongol empire was quite liberal with tolerance for many different cultures and religions. Sure they had some tendancies that seem barabaric to our eyes but nothing out of the ordinary for their times.
Genghis really only set up the empire, it was Kubali who took the horsemen across the steppes into Europe.
It was only the death of the Khan that prevented Europe from being overrun. The last ditch defense by Teutonic Knights, in Poland IIRC, was to have been the final stand.
I'd love to find out what an alternative history would have been like if the Mongols had conquered Europe.
