This people, also called Dilie 遞烈 or Diliede 敵烈得 was relative to the Wugu 烏古 and roamed the area of the river Kerulen in modern Mongolia during the 9th and 10th centuries. In 930 they submitted to the Khitan empire of Liao 遼 but often rose in rebellion against the Khitan control. In 1004 one of the imperial consorts of Emperor Liao Shengzong 遼聖宗, and her kinsman Xiao Talin 蕭撻凜 that should control this region, installed prefectures (zhou 州) to administer the region roamed by the Wugu and Dilie as an army command (dutong junsi 都統軍司) with the seat at Hedong 河董城 (near Bulgan/Mongolia, Kerulen River). When the Jurchen took over the north of China, they divided the Dilie tribes into different parts and resettled them to different areas, most of them to Pangge 龐葛城 (modern Qiqihar 齊齊哈爾/Heilongjiang). One tribe followed the Khitan to the west into their new empire of Western Liao (Xiliao 西遼).
