Sino-Sikh War (1841- 42): The Sino-Sikh War (also referred to as the Invasion of Tibet or the Dogra War) was fought from May 1841 to August 1842, between the forces of Qing China and the Sikh Empire after General Zorawar Singh Kahluria invaded western Tibet. At the time of the war, the Dogra dynasty was a vassal of the Sikh Empire, and so the conflict is also known as the Dogra War. The Sikh army was routed and the Qing counterattacked but were defeated in Ladakh resulting in an overall military stalemate. The Treaty of Chushul was signed in 1842 maintaining the status quo ante bellum.
The Qing dynasty, also known as the Qing Empire, officially the Great Qing was the last imperial dynasty of China, established in 1636 and ruling China from 1644 to 1912. It was preceded by the Ming dynasty and succeeded by the Republic of China. The Qing multi-cultural empire lasted almost three centuries and formed the territorial base for the modern Chinese state.
