大遼本非契丹國號說

The Great Liao Did Not Represent the Khitan Empire Initially

契丹君主耶律德光滅後晉所建號之"大遼",本非契丹國號,實係漢地新朝、國中之國。德光北歸後,中原旋即易主,"大遼"名存實亡,方施於燕雲十六州,成爲契丹專用於漢地的國號。

After conquering the Later Jin,the Khitan Emperor YelvDeguang established a new dynasty in the Central Plain,which controlled a vassal kingdom of the Khitan Empire and was called the Great Liao.Although this vassal kingdom soon collapsed,as a symbol,the Great Liao survived as the official representation of the Khitan Empire in the agricultural regions under its rule.
