|Genghis The Legend of the Ten: A little known fact is that Chinggis Khaan, better known as Genghis Khan, would collect orphans from his bloody battlefields and have his own
mother raise them. These adopted brothers grew up to become his most loyal officials and advisers. Khaan organised his Mongol soldiers into groups according to the
decimal system. Soldiers were arranged in units of 10 ("aravt"), 100 ("zuut"), 1,000 ("minghan") and 10,000 ("tumen").
