 The Liao employed two separate governments operating in parallel with one another: a Northern Administration in charge of Khitan and other nomadic peoples, most of whom lived in the northern side of Liao territory, and a Southern Administration in charge of the Chinese populace that lived predominantly in the southern side. When Abaoji first established the system, these two governments did not have strict territorial boundaries, but Emperor Shizong established formally delineated boundaries for the two administrations early in his reign. The newly delineated Northern Administration had large Chinese, Balhae, and Uighur populations, and was given its own set of parallel northern and southern governments.
