Huns
The Huns were a nomadic people who lived in Central Asia, the Caucasus, and Eastern Europe between the 4th and 6th centuries CE. 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 CE, the Huns had arrived on the Volga, causing the westwards movement of Goths and Alans.
