Although the Mongols seemed to be chaotic, bloodthirsty and unreliable, their rise was not the result of a lack of order, but precisely the opposite: ruthless planning, streamlined organisation and a clear set of strategic objectives were the key to establishing the largest land empire in history. The inspiration behind the Mongol transformation was a leader named Temüjin, or blacksmith. We know him by his title and nickname of “universal ruler,” or perhaps, “fierce ruler”: Činggis, or Genghis Khan.
