The Kidarites, or Kidara Huns, were a dynasty that ruled Bactria and adjoining parts of Central Asia and South Asia in the 4th and 5th centuries. The Kidarites belonged to a complex of peoples known collectively in India as the Huna, and in Europe as the Chionites (from the Iranian names "Xwn"/"Xyon"), and may even be considered as identical to the Chionites. The 5th century Byzantine historian Priscus called them Kidarites Huns, or "Huns who are Kidarites". The Huna/ Xionite tribes are often linked, albeit controversially, to the Huns who invaded Eastern Europe during a similar period. They are entirely different from the Hephthalites, who replaced them about a century later.
