Germanic tribes frequently clashed with which central Asian group?
The Huns were a nomadic people who likely originated near modern Kazakhstan, but the timing of their appearance is unknown. By the fourth century CE, they were raiding lands held by the Visigoths, Ostrogoths, Rome, and Byzantium. The Huns reached their height under Attila, striking fear and capturing territory with their military skills and horsemanship. His death in 453 CE led to internal divisions, which saw the Hun empire collapse by 469 CE.
