Abstract: | The Liao Dynasty inherited the old system from the Tang and Five Dynasties, with supervisor set up in the army. The Liao Dynasty still continue to use the existing two types of supervisors from the Five Dynasties, one is temporary supervisor, the other one is permanent supervisor. The temporary supervisor in Liao Dynasty is basically same with the Five Dynasties, but only used on armies with large forces. Compared with the five Dynasties, the permanent supervisor has a great development, which can be seen from two aspects, one is the extension of supervising scope, second is the enhancement of power. |
