a Scottish nobleman, George Bogle, travelled to Shigatse to investigate prospects of trade for the East India Company. His efforts, while largely unsuccessful, established permanent contact between Tibet and the Western world. However, in the 19th century, tensions between foreign powers and Tibet increased. The British Empire was expanding its territories in India into the Himalayas, while the Emirate of Afghanistan and the Russian Empire were both doing likewise in Central Asia. In 1904, a British expedition to Tibet, spurred in part by a fear that Russia was extending its power into Tibet as part of the Great Game, was launched. Although the expedition initially set out with the stated purpose of resolving border disputes between Tibet and Sikkim, it quickly turned into a military invasion. The British expeditionary force, consisting of mostly Indian troops, quickly invaded and captured Lhasa, with the Dalai Lama fleeing to the countryside. Afterwards, the leader of the expedition, Sir Francis Younghusband, negotiated the Convention Between Great Britain and Tibet with the Tibetans, which guaranteed the British great economic influence but ensured the region remained under Chinese control. The Qing imperial resident, known as the Amban, publicly repudiated the treaty, while the British government, eager for friendly relations with China, negotiated a new treaty two years later known as the Convention Between Great Britain and China Respecting Tibet. The British agreed not to annex or interfere in Tibet in return for an indemnity from the Chinese government, while China agreed not to permit any other foreign state to interfere with the territory or internal administration of Tibet. In 1910, the Qing government sent a military expedition of its own under Zhao Erfeng to establish direct Manchu-Chinese rule and, in an imperial edict, deposed the Dalai Lama, who fled to British India. Zhao Erfeng defeated the Tibetan military conclusively and expelled the Dalai Lama's forces from the province. His actions were unpopular, and there was much animosity against him for his mistreatment of civilians and disregard for local culture. Post-Qing period After the Xinhai Revolution (1911–12) toppled the Qing dynasty and the last Qing troops were escorted out of Tibet, the new Republic of China apologized for the actions of the Qing and offered to restore the Dalai Lama's title. The Dalai Lama refused any Chinese title and declared himself ruler of an independent Tibet. In 1913, Tibet and Mongolia concluded a treaty of mutual recognition.
