The Eurasian Steppes and the Wrath of Khans

With Ukraine and Crimea in the news, it is good excuse to look back at history of the region.  

The Eurasian Steppe is like the North American Prairie, only it is around five thousand miles long, stretching from the Hungarian frontier to central China.

Genghis Khan Spring 1206 – August 1227

Wrath of Khans I
Wrath of Khans II
Wrath of Khans III
Wrath of Khans IV
Wrath of Khans V

Update:

Global Warming helped Genghis Kahn?  Funny he used the Russian winter to successfully attack Russia and Poland.  Mongol horses could cross rivers and swamps when frozen.
