Zanskar is a subdistrict or tehsil of the Kargil district, which lies in the eastern half of the Indian state of Jammu and Kashmir. The administrative centre is Padum. Zanskar, together with the neighbouring region of Ladakh, was briefly a part of the kingdom of Guge in Western Tibet. Zanskar covers an area of some 7,000 square kilometres, at a height of between 3,500 and 7,000 metres. It consists of the country lying along the two main branches of the Zanskar river. The population lives mainly in scattered small villages, the largest being the capital Padum, with nearly 700 inhabitants. Most of the villages are located in the valleys of the Zanskar river and its two main tributaries. Given the isolation of this region, the inhabitants tend towards self-sufficiency, and until recently lived in almost complete autarky.
