He is the ruler of one of the greatest empires in world’s history. The word Khan means universal ruler. He conquered Turkestan, Iran, Afghanistan and South Russia. He was fearsome warrior by the style of his insane brutality and horrific cruelty. T he standard behaviour after taking a city was he drove the population outside the city walls; men with useful skills might be enslaved. Young men will be taken for military purpose. The several thousands are swept down like cattle to be killed, generally decapitated, and their heads stacked in neat pyramids. The women were, without exception, raped. A few might be taken for slaves or concubines, and the rest also killed. If an example was to be made of an execution of a particular city, then no one would be spared, for any purpose. The inhabitants might be driven out through a gate and decapitated as they walked through it, in a short of ghastly deathly belt. Sometimes each Mongol soldier was designated a number of executions to perform, which on an occasion was as high as five hundred per man. This could take days to perform, even with the famous stamina of the Mongol troops, particularly if the order was given that no living thing was to escape. Even dogs and cats were then executed and babies in the womb were run through with swords. This was all performed in a highly disciplined fashion. Finally the city would be set on fire and afterwards flooded where conditions permitted. The prospect of all this happening produced some fairly drastic reactions. At Peking, 60,000 women threw themselves off the city walls rather than face the Mongols; when the siege left them starving, the whole population resorted to cannibalism rather than surrender. China was conquered by Kublai a grandson of Genghis Khan who ruled as first emperor of the Yan Dynasty (1271-1368).
