Xiongnu
The Xiongnu () were a confederation of nomadic peoples who, according to ancient Chinese sources, inhabited the eastern Asian Steppe from the 3rd century BC to the late 1st century AD. Chinese sources report that Modu Chanyu, the supreme leader after 209 BC, founded the Xiongnu Empire.
Xiongnu
Chinese sources link the Tiele people and Ashina to the Xiongnu, not all Turkic peoples. According to the "Book of Zhou" and the "History of the Northern Dynasties", the Ashina clan was a component of the Xiongnu confederation, but this connection is disputed, and according to the "Book of Sui" and the "Tongdian", they were "mixed nomads" () from Pingliang. The Ashina and Tiele may have been separate ethnic groups who mixed with the Xiongnu. Indeed, Chinese sources link many nomadic peoples ("hu"; see "Wu Hu") on their northern borders to the Xiongnu, just as Greco-Roman historiographers called Avars and Huns "Scythians". The Greek cognate of "Tourkia" () was used by the Byzantine emperor and scholar Constantine VII Porphyrogenitus in his book "De Administrando Imperio", though in his use, "Turks" always referred to Magyars. Such archaizing was a common literary "topos", and implied similar geographic origins and nomadic lifestyle but not direct filiation. Some Uyghurs claimed descent from the Xiongnu (according to Chinese history "Weishu", the founder of the Uyghur Khaganate was descended from a Xiongnu ruler), but many contemporary scholars do not consider the modern Uyghurs to be of direct linear descent from the old Uyghur Khaganate because modern Uyghur language and Old Uyghur languages are different. Rather, they consider them to be descendants of a number of people, one of them the ancient Uyghurs.
