The Huns were a group of nomadic people who first appeared from east of the Volga River, and were first mentioned as Hunnoi by Tacitus. Initially being near the Caspian Sea in 91 AD, the Huns migrated to the southeastern area of the Caucasus by about 150 AD and into Europe by 370 AD, where they established a vast Hunnic Empire there. Since de Guignes linked them with the Xiongnu, who had been northern neighbours of China 300 years prior to the emergence of the Huns, considerable scholarly effort has been devoted to investigating such a connection. However, there is no scholarly consensus on a direct connection between the dominant element of the Xiongnu and that of the Huns.
