This region formed part of the erstwhile Kingdom of Ladakh. In fact it is believed to be the first to be inhabited by the early colonizers of Ladakh, the Indo-Aryan Mons from across the Great Himalayan range, assorted Dard immigrants from down the Indus and the Gilgit valleys and itinerant nomads from the Tibetan highlands. Also, being contiguous with Baltistan, Kashmir, Kulu etc. these valleys are believed to have served as the initial recipients of successive ethnic and cultural influences emanating from the neighbouring regions. Thus, while the Monks are believed to have introduced north-Indian Buddhism to these valleys, the Dard and Balti immigrants are credited with introducing farming and the Tibetan nomads with the tradition of herding and animal husbandry.

About 15,000 sq. kms. in area, Kargil district has an agrarian population of approximately 120,000 people, who cultivate the land, along the course of the drainage system, wherever artificial irrigation from mountain streams is possible. About 85% are Muslims, mainly of the Shia sect, Islam having been introduced to the original Buddhist population around the middle of the 16th century by missionaries from Kashmir and Central Asia. Their descendants, locally titled Agha, are mostly religious scholars who continue to hold sway over the population, even as the age-old traditions of Buddhist and animistic origin are discernible in the culture. Many elements of the ancient supernatural belief systems, especially many traditions connected with agricultural practices, are still followed with subdued reverence.
