Genghis Khan has a wide span of control, as he has the power to control every single unit and groups in his nation. However, the hierarchy is a very tall one. A leader who has conquered China and even to parts of Europe, he will not be able to control every single unit he has. But again, as he is an autocratic leader, he can always check on whatever units as he please, therefore, even though he is an autocratic leader and having a wide span of control, the hierarchy is still a very tall one.
