The "White Huns", also known as the White Hunas, in Iranian as the Spet Xyon and in Sanskrit as the Sveta-huna, were a sub-group of the Huna and/or Xionites. The White Huns are sometimes regarded as synonymous with the Hephthalites, but may have included other tribes as well. They are well known for their conquest and occupation of North India, particularly the Punjab region.
