Nomadic people in the context of "Five Barbarians"

The Huns were a nomadic people who lived in Central Asia, the Caucasus, and Eastern Europe between the 4th and 6th centuries AD. According to European tradition, they were first reported living east of the Volga River, in an area that was part of Scythia at the time. By 370 AD, the Huns had arrived on the Volga, causing the westwards movement of Goths and Alans. By 430, they had established a vast, but short-lived, empire on the Danubian frontier of the Roman empire in Europe. Either under Hunnic hegemony, or fleeing from it, several central and eastern European peoples established kingdoms in the region, including not only Goths and Alans, but also Vandals, Gepids, Heruli, Suebians and Rugians.

The Huns, especially under their King Attila, made frequent and devastating raids into the Eastern Roman Empire. In 451, they invaded the Western Roman province of Gaul, where they fought a combined army of Romans and Visigoths at the Battle of the Catalaunian Fields, and in 452, they invaded Italy. After the death of Attila in 453, the Huns ceased to be a major threat to Rome and lost much of their empire following the Battle of Nedao (c. 454). Descendants of the Huns, or successors with similar names, are recorded by neighboring populations to the south, east, and west as having occupied parts of Eastern Europe and Central Asia from about the 4th to 6th centuries. Variants of the Hun name are recorded in the Caucasus until the early 8th century.

In the ancient Greco-Roman world, Sarmatia was a geographic region that encompassed the western Eurasian steppe. It was inhabited by the Sarmatians, an ancient Eastern Iranian equestrian nomadic people.

The Romans gave the name Sarmatia to the region which the ancient Greeks had formerly called Scythia because it had been inhabited by the Scythians. Beginning in the late 4th century BC the Sarmatians, a nomadic Iranian people related to the Eastern Iranic Scythians, moved from the east into the Pontic steppe, where they replaced the Scythians as the dominant power. Due to the Sarmatian incursion, "Sarmatia Europea" replaced "Scythia" as the name for the region.

The Wuhuan (simplified Chinese: 乌桓; traditional Chinese: 烏桓; pinyin: Wūhuán, < Eastern Han Chinese: *ʔɑ-ɣuɑn, < Old Chinese (c. 78 BC): *ʔâ-wân < *Awar) were a Proto-Mongolic or para-Mongolic nomadic people who inhabited northern China, in what is now the provinces of Hebei, Liaoning, Shanxi, the municipality of Beijing and the autonomous region of Inner Mongolia.
