The Tibetan name of "Demchok" literally translates to "seize resilience".
Description
The village lay 36.5 km east of Ukdungle. Demchok was on an old route linking Ladakh and Tibet along the bank of the Indus River, which ran mostly through plains to Lake Manasarovar approximately 300 km away.
17th century
The Chronicles of Ladakh mention that, at the conclusion of the Tibet–Ladakh–Mughal War in 1684, the Ganden Phodrang government of Tibet and the Namgyal dynasty of Ladakh agreed on the Treaty of Tingmosgang. The chronicles describe the treaty as fixing the boundary at "the Lhari stream at Demchok", which was described as flowing into the Indus at Demchok and dividing Demchok into two halves. According to Alexander Cunningham, "A large stone was then set up as a permanent boundary between the two countries, the line of demarcation drawn from the village of Dechhog to the hill of Karbonas."
A British boundary commission in 1846–1847 on the borders of the former princely state of Jammu and Kashmir described the village as: The commission placed the border between the former princely state of Jammu and Kashmir and Qing Tibet on the Indus at Demchok. The Survey of Kashmir, Ladak, and Baltistan or Little Tibet of 1847 to 1868 under the Great Trigonometrical Survey of India then made several adjustments to the boundary, described by Alastair Lamb as moving "sixteen miles downstream on the Indus from Demchok". However, Indian commentators state that the revenue records from the period of the survey show that the Demchok area was administered by Ladakh. In 1904–05, a tour report by the Wazir Wazarat of Ladakh described the Tibetan side of the hamlet to have 8 to 9 huts of zamindars and described the Ladakhi side as having two.
