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). 敵烈部 辽金时东北部族名。又作敌拉、迭烈、敌剌、迪里、迪烈子、敌烈得(德)、迪烈得(德)、迭烈德、达里底、德哷勒。始见于《辽史》，辽太宗天显五年(930)“敌烈来贡”为最早记载。族属一说属突厥语系民族，源于※丁零、※铁勒(或※高车)之一部，唐时称拔野古。其活动地域在今克鲁伦河中游一带。时有8部，史称“八部敌烈”，或“敌烈八部”(一说“八部”为泛称，非确指，为“诸部”之意)。经济以畜牧为主，盛产马、驼。※契丹常将其与※乌古部合称为乌古敌烈部。辽穆宗应历十五年(965)前后被契丹降服，然时叛时服，契丹将部分俘户置部，辽圣宗34部中有北敌烈部、迭鲁敌烈部，即“圣宗以敌烈户置，隶北府，节度使属乌古敌烈统军司。”尚有敌烈皮室军。北面军官中置有“敌烈军详稳司”、“敌烈皮室详稳司”等署衙。原部为辽属国，对辽朝贡无常。辽置迪烈德国王府以治。寿昌二年(1096)，徙敌烈、乌古部于乌纳水，以扼北边之冲要。辽末附金，东徙，金设乌古敌烈统军司统辖。金末元初，逐渐与女真人、蒙古人融合。 高文德 (ed. 1995 )吉林教育出版社 《中国少数民族史大辞典》 第1882頁
