The Burusho or Brusho, also known as the Hunza people or Botraj,[4][2] live in Hunza, Nagar, Chitral, and in valleys of Gilgit–Baltistan in northern Pakistan,[6] with a smaller group of around 350 Burusho people residing in Jammu and Kashmir, India as well.[5][7] Their language, Burushaski, has been classified as a language isolate.[8] Although their origins are unknown, it is likely that the Burusho people "were indigenous to northwestern India (current day Pakistan) and were pushed into their present homeland by the movements of the Indo-Aryans who migrated to the subcontinent in 1800 B.C.[9]
