Chinese expedition to Tibet (1720)
The 1720 Chinese expedition to Tibet or the Chinese conquest of Tibet in 1720 was a military expedition sent by the Qing empire to expel the invading forces of the Dzungar Khanate from Tibet and establish a Chinese protectorate over the country. The expedition occupied Lhasa and some claim it marked the beginning of Qing rule in Tibet, which lasted until the empire's fall in 1912.
