Huns

After precipitating the invasions of the Germanic tribes in the fourth century, the central Asian Huns, under their ruler Attila, also invaded the Roman Empire and conquered much of central and eastern Europe. In 451 - 452, they invaded Gaul and Italy, but these territories were successfully defended by a coalition of Roman and Germanic troops. The Huns were defeated at Châlons in 451 and soon after the death of Attila in 453, the Hunnic Empire fell apart. Other Asian nomadic peoples who entered Europe were the Avars in the sixth century, the Bulgars in the sixth and seventh centuries, and the Magyars in the ninth century. The Magyars settled in the
Danubian plain and their descendants still inhabit modern Hungary.
