Alans

Alans, a nomad race, of warlike equestrian habits, belonging to the great nation of the Sarmatians. First heard of in 65 B.C., they gradually spread northwards from the Caucasus to the Don and the Volga. In 375 they were conquered and scattered by the Huns; and many of them, in 411, with the Suevi and Vandals, invaded the Spanish peninsula, and settled in Portugal, whence in 429 they were ousted by the West Goths, and passed over to Africa.
