The serfdom in Tibet controversy is a prolonged public disagreement over the extent and nature of serfdom in Tibet prior to the annexation of Tibet into the People's Republic of China (PRC) in 1951. The debate is political in nature, with some arguing that the ultimate goal on the Chinese side is to legitimize Chinese control of the territory now known as the Tibet Autonomous Region or Xizang Autonomous Region, and others arguing that the ultimate goal on the Western side is to weaken or undermine the Chinese state. The argument is that Tibetan culture, government, and society were barbaric prior to the PRC takeover of Tibet and that this only changed due to PRC policy in the region. The pro-Tibetan independence movement argument is that this is a misrepresentation of history created as a political tool in order to justify the Sinicization of Tibet.
