The Kalasha (Kalasha: Kaĺaśa, Nuristani: Kasivo) or Kalash, are an Indo-Aryan Dardic indigenous people residing in the Chitral Districtof Khyber-Pakhtunkhwa province of Pakistan. They speak the Kalasha language, from the Dardic family of the Indo-Aryan branch. They are considered unique among the peoples of Pakistan. They are also considered to be Pakistan’s smallest religious community.
The neighboring Nuristani people of the adjacent Nuristan (historically known as Kafiristan) province of Afghanistan once practiced a form of ancient Hinduism adhered to by the Kalash. By the late 19th century much of Nuristan had been converted to Islam, although some evidence has shown the people continued to practice their customs.Over the years, the Nuristan region has also been the site of much war activity that has led to the death of many endemic Nuristanis and has seen an inflow of surrounding Afghans to claim the vacant region, who have since settled among with the remaining natives. The Kalash of Chitral maintained their own separate cultural traditions.
The most important Kalash festival is the CHAWMOS
