Ladakh is a region administered by India as a union territory, and constituting a part of the larger region of Kashmir, which has been the subject of dispute between India, Pakistan, and China since 1947. It is bordered by Tibet to the east, the Indian state of Himachal Pradesh to the south, Jammu and Kashmir and Gilgit-Baltistan to the west, and the southwest corner of Xinjiang across the Karakoram Pass in the far north. It extends from the Siachen Glacier in the Karakoram range to the north to the main Great Himalayas to the south. The eastern end of Ladakh, consisting of the uninhabited Aksai Chin plains, has been under Chinese control since 1962. Until 2019, Ladakh was a region of the state of Jammu and Kashmir. In August 2019, the Parliament of India passed an act by which Ladakh became a union territory on 31 October 2019.
