In order for Tibet to have traditionally been viewed as part of the Chinese nation, there is no requirement that it have been under Chinese rule continuously. Like many other parts of “China”, it was ruled by China during times of imperial strength, and when governments weakened, so too did central authority. In this sense Tibet has a lot in common with Manchuria, another region that tended to drift towards autonomy during times of dynastic weakness.  One thing however has been clear – the variation in sovereignty in Tibet has been between autonomy and Chinese sovereignty. Even in the 9th century when Tibetan armies were outside the gates of the Tang Dynasty Capital of Chang’an, the Tibetans remained nominally the Emperor’s subjects as proclaimed by a monument from 823 stating “their territories be united as one”. [1]  Tibet’s independence between 1904/11 and 1950 was consistent with this cycle. Tibet gained autonomy when China weakened, and this autonomy was as much a product of British influence as it was of any Tibetan desires themselves. In 1950, with China reunited under a strong government, Chinese sovereignty returned. It was undoubtedly the case that the local elites who were displaced resented this change, just as their predecessors did the previous times throughout history when Chinese sovereignty was restored, but this does not justify independence, especially when Tibetan independence in the past has always been a product of the dual factors of Chinese weakness and the strength of foreign powers in the region, neither of which is operative right now.
