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
The Xiongnu-Hun hypothesis originated with the 18th-century French historian Joseph de Guignes, who noticed that ancient Chinese scholars had referred to members of tribes associated with the Xiongnu by names similar to "Hun", albeit with varying Chinese characters. Étienne de la Vaissière has shown that, in the Sogdian script used in the so-called "Sogdian Ancient Letters", both the Xiongnu and Huns were referred to as γwn ("xwn"), indicating that the two were synonymous. Although the theory that the Xiongnu were precursors of the Huns known later in Europe is now accepted by many scholars, it has yet to become a consensus view. The identification with the Huns may be either incorrect or an oversimplification (as would appear to be the case with a proto-Mongol people, the Rouran, who have sometimes been linked to the Avars of Central Europe).
