Ladakh "land of high passes" is a region of India in the state of Jammu and Kashmir that lies between the Kunlun mountain range in the north and the main Great Himalayas to the south, inhabited by people of Indo-Aryan and Tibetan descent. It is one of the most sparsely populated regions in Jammu and Kashmir and its culture and history are closely related to that of Tibet.
Historically, the region included the Baltistan (Baltiyul) valleys, the northern Indus Valley, the remote Zangskar, Lahaul and Spiti to the south, Aksai Chin and Ngari, including the Rudok region and Guge, in the east, and the Nubra valleys to the north.
Contemporary Ladakh borders Tibet to the east, the Lahaul and Spiti to the south, the Vale of Kashmir, Jammu and Baltiyul regions to the west, and the trans–Kunlun territory of Xinjiang to the far north. Ladakh is renowned for its remote mountain beauty and culture.
In the past Ladakh gained importance from its strategic location at the crossroads of important trade routes, but since the Chinese authorities closed the borders with Tibet and Central Asia in the 1960s, international trade has dwindled except for tourism. Since 1974, the Government of India has successfully encouraged tourism in Ladakh. Since Ladakh is a part of strategically important Jammu and Kashmir, the Indian military maintains a strong presence in the region.
The largest town in Ladakh is Leh. Almost half of Ladakhis are Tibetan Buddhists and the rest are mostly Shia Muslims. Leh is followed by Kargil as the largest town in Ladakh. Some Ladakhi activists have in recent times called for Ladakh to be constituted as a union territory because of perceived unfair treatment by Kashmir and Ladakh's cultural differences with predominantly Muslim Kashmir.
