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.

Lajos Ligeti was the first to suggest that the Xiongnu spoke a Yeniseian language. In the early 1960s Edwin Pulleyblank was the first to expand upon this idea with credible evidence. In 2000, Alexander Vovin reanalyzed Pulleyblank's argument and found further support for it by utilizing the most recent reconstruction of Old Chinese phonology by Starostin and Baxter and a single Chinese transcription of a sentence in the language of the Jie people, a member tribe of the Xiongnu Confederacy. Previous Turkic interpretations of the aforementioned sentence do not match the Chinese translation as precisely as using Yeniseian grammar. Pulleybank and D. N. Keightley asserted that the Xiongnu titles "were originally Siberian words but were later borrowed by the Turkic and Mongolic peoples". The Xiongnu language gave to the later Turkic and Mongolian empires a number of important culture words including Turkish tängri, Mongolian tenggeri, was originally the Xiongnu word for “heaven”, chengli (tháːŋ-wrə́j). Titles such as tarqan and tegin and kaghan were also inherited from the Xiongnu language.
