The Tibet Autonomous Region, officially the Xizang Autonomous Region, often shortened to Tibet or Xizang, is an autonomous region of China and is part of Southwestern China. It was formally established in 1965 to replace the Tibet Area, the former administrative division of the PRC established after the annexation of Tibet. The establishment was about five years after the 1959 Tibetan uprising and the dismissal of the Kashag, and about 13 years after the original annexation.
