That Tibet has been an integral part of China for seven hundred years is held by all Chinese and recognized, at times with reservations, by all foreign powers. It is also the view of most Tibetans, though movements of secession have at times occurred, none of which rallied enough strength to succeed.

The historical relation of Tibet with China is usually taken as beginning in 641 A.D. when Tibet was first united under a strong central government, Tibet was again a part. The last time this happened was early in the present century when the Manchu Dynasty fell and China broke into spheres of warlords. In Tibet the Thirteenth Dalai Lama declared an "independence" that never became unanimous. Tibetan warlords fought Szechuan warlords for possession of a province marked on the maps of Chiang Kai-shek as Sikang. Chiang's government never succeeded in unifying the outer areas of China, neither Manchuria, Inner Mongolia, Sinkiang or Tibet. Yet even in this period, Tibetans sought the sanction of the Kuomin-tang government for the ordination of the Fourteenth Dalai Lama and the Tenth Panchen Erdeni. By 1942 and 1946, Tibet's local government, the kashag, was sending its deputies to Chiang's "National Congress of China", in Chungking and then in Nanking.

This loose yet permanent relation of Tibet within China has been recognized in the diplomacy of foreign powers. No foreign power in seven centuries has sent an ambassador to Lhasa or recognized Tibet as a separate nation. Even when Britain seized Lhasa by armed force in 1904 and dictated a treaty in the Potala Palace, the bill for the £750,000 indemnity was sent to the Emperor in Peking and collected from him.
