The Kalash is a very small ethnic community of the mountain people, surrounded by the mountains of Hindu-Kush called the Kafir Kalash or Kafiristan, kafir means non-Muslim and Kafiristan means the land of non-Muslims. This small mountain community is not Muslim by religion. They have their own religion, language, cultural and dress, those are unique in the world. Their religion is little in common with Islam and it is thought that it may have roots in early Vedic religion. There is one creator God and several other Gods. The people of these valleys are called Kalashi, who are inhabited only in three valleys in the eastern Hindukush Mountain Range, Birir, Bumburate and Rumbur. These three valleys lie close to the border with Afghanistan (Nuristan), surrounded by the high peaks and they are hardly 3000 altogether.
Theories about as how the people of Kalash came to inhabit their lofty valleys, some say that they are the descendants of the tribes who intermarried with followers of Alexander the Great, but there is no any evidence that he passed this way. Some people discern traces of Greek civilization and physical characteristics among the Kalash. The Kalash are fair in complexion and rosy cheeked some people are
blond and blue eyes, whatever their origin, are unique with their culture, religion and language in this part of the world.
