Political map of South & Southwest Asia 17 August 1912 (Tibetan Independence): The collapse of the Chinese Empire (Xinhai Revolution) allowed Tibet to expel its Chinese garrison (Xinhai Lhasa turmoil) and declare independence. When the new Republic of China (Republic of China (1912%E2%80%9349)) attempted to reclaim the Himalayan kingdom, it was warned off by the British, who, while not formally recognizing Tibetan independence, would not allow the restoration of Chinese control.
