The history of the Mongol armies is a catalogue of superlatives. No armies in history have ever won so many battles or conquered so much territory. No army has ever provoked such justifiable terror and loathing in its victims, or slaughtered so many of its vanquished. What other army in history has marched on Russia in the winter and survived, let alone won victories? The stories of these and many other amazing feats of this 'barbarian' people are here brought vividly to life by Stephen Turnbull, from the birth of Genghis Khan in the wind-swept steppes of Mongolia, through the conquest of China and beyond.
