Genghis Khan is the legendary founder of the Mongol Empire, the largest state in the medieval world, and one of the greatest conquerors in world history. His troops made a hole in the Great Wall of China and took Beijing. With merciless massacres and robbery, they broke the resistance of the inhabitants of Central Asia, Afghanistan, Persia and Southern Rus'. In 1237–1242 they invaded Europe. The speed and scale of their conquests (and the terrible burial mounds they left behind) gave rise to the spread of myths about Genghis Khan... But the Great Khan was more than just a conqueror. His greatest achievement was the unification of the irreconcilable Mongol tribes in the harsh conditions of the Asian steppes and their organization into a mobile and disciplined army, which opposed their rivals with stunning effect. The book offered to the reader by Leo de Hartog, a Dutch specialist on Mongolia, who has comprehensively studied this topic, is the most complete today's biography of the “conqueror of the world” Genghis Khan.
