They have long been thought of as being the descendants of Alexander the Great's soldiers; but now it's the first time that the Kalash people will get recognition as a distinct ethnic community in Pakistan. The Indo-Aryan Dardic indigenous people residing in the Chitral District of Khyber-Pakhtunkhwa province of Pakistan, near the border of Afghanistan won the right to be counted separately during the census carried out in Pakistan - the first in two decades. The 4,000 people have attracted interest by ethnologues and anthropologists, maintaining distinct religious and cultural customs, separate from local Muslims - they are polytheists and worship nature. The Kalash people are believed to be descendants of Alexander's soldiers who were left behind while the Macedonian warrior marched on to the Indian subcontinent. DNA analysis asserted that no East or South Asian lineages were detected and that the Kalash population is composed of western Eurasian lineages.
