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.
Origin of the Huns
At the beginning of the twentiethcentury, German Sinologist Friedrich Hirth discovered passages in the Chinese annals that he believed proved the connection between the Huns and the Xiongnu. Hirth's work convinced many, and by the 1940s there was a general consensus among historians and archaeologists that the Xiongnu and the Huns were related. However, Otto J. Maenchen-Helfen showed conclusively that Hirth had misinterpreted the Chinese annals in 1945. Maenchen-Helfen also argued against the identification based on then-current archaeology and on ethnographic grounds. While he did not address the question in his most important work, "The World of the Huns" (1973), Maenchen-Helfen would go on to cast doubt on new theories that equated the Huns and the Xiongnu on the basis of their names in several articles. Maenchen-Helfen's skepticism was also taken up by prominent Eurasianist Denis Sinor.
