The Flag of Tibet that introduced by the 13th Dalai Lama in 1912 and outlawed by the People's Republic of China in 1959.
Tibet is a Chinese-ruled plateau region in Asia, north of the Himalayas. It is home to the indigenous Tibetan people, and to some other ethnic groups such as Monpas and Lhobas, and is inhabited by considerable numbers of Han and Hui people. Tibet is the highest region on earth, with an average elevation of 4,900 metres (16,000 ft). It is sometimes referred to as the roof of the world.
During Tibet's history, it has existed as a region of separate sovereign areas, a single independent entity and as a part of successive Chinese dynasties. Tibet was first unified under King Songtsän Gampo in the 7th century. At various times from the 1640s until 1950s, a government nominally headed by the Dalai Lamas, a line of spiritual political leaders, ruled a large portion of the Tibetan region. During some of this period, the Tibetan administration was subordinate to the Chinese empire of the Qing Dynasty.
In 1913 the 13th Dalai Lama expelled Qing's representatives and troops from what is now the Tibet Autonomous Region. While the expulsion was seen as an assertion of Tibetan autonomy, Tibet's proclaimed independence was not accepted by the government of China, nor did Tibet receive foreign diplomatic recognition.
Following a decisive invasion and battle at Chamdo in 1950, the Communist Party of China gained control of the region of Kham to the West of the Upper Yangtze River. The next year the 14th Dalai Lama and his government signed the Seventeen Point Agreement. In 1959, he together with a group of Tibetan leaders and followers fled to India and set up the Government of Tibet in Exile in Dharamshala.
