White Huns
The Hephthalites or Ephthalites, sometimes called the White Huns, were a people who lived in Central Asia during the 5th to 8th centuries CE, and were a part of what numismatist Robert Göbl calls Iranian Huns. They formed an empire, the Imperial Hephthalites, and were militarily important from 450 CE, when they defeated the Kidarites, to 560 CE, when combined forces from the First Turkic Khaganate and the Sasanian Empire defeated them.
