Tibet is a region in East Asia covering much of the Tibetan Plateau that is currently administered by People's Republic of China as the Tibet Autonomous Region and claimed by the Republic of China as the Tibet Area and the Central Tibetan Administration. The CTA uses the snow lion flag of the independent Tibetan state from 1912 to 1951. The snow lion flag has become a pro-independence symbol and is outlawed in the People's Republic of China after the 1959 Tibetan uprising. The PRC uses its national flag instead to represent Tibet.
