Alans and Slavs
Some historians argue that the arrival of the Huns on the European steppe forced a portion of Alans previously living there to move northwest into the land of Venedes, possibly merging with Western Balts there to become the precursors of historic Slav nations.
It's believed that some Alans resettled to the North (Barsils), merging with Volga Bulgars and Burtas, eventually transforming to Volga Tatars.
