full_context: Document 1: Sino-Tibetan relations during the Ming dynasty: Josef Kolmaš, a sinologist, Tibetologist, and Professor of Oriental Studies at the Academy of Sciences of the Czech Republic, writes that it was during the Qing dynasty "that developments took place on the basis of which Tibet came to be considered an organic part of China, both practically and theoretically subject to the Chinese central government." Yet he states that this was a radical change in regards to all previous eras of Sino-Tibetan relations.

Document 3: Sikkim: Phuntsog Namgyal was succeeded in 1670 by his son, Tensung Namgyal, who moved the capital from Yuksom to Rabdentse (near modern Pelling). In 1700, Sikkim was invaded by the Bhutanese with the help of the half-sister of the Chogyal, who had been denied the throne. The Bhutanese were driven away by the Tibetans, who restored the throne to the Chogyal ten years later. Between 1717 and 1733, the kingdom faced many raids by the Nepalese in the west and Bhutanese in the east, culminating with the destruction of the capital Rabdentse by the Nepalese. In 1791, China sent troops to support Sikkim and defend Tibet against the Gorkha Kingdom. Following the subsequent defeat of Gorkha, the Chinese Qing dynasty established control over Sikkim.
Document 4: Sino-Tibetan relations during the Ming dynasty: P. Christiaan Klieger, an anthropologist and scholar of the California Academy of Sciences in San Francisco, writes that the vice royalty of the Sakya regime installed by the Mongols established a patron and priest relationship between Tibetans and Mongol converts to Tibetan Buddhism. According to him, the Tibetan lamas and Mongol khans upheld a "mutual role of religious prelate and secular patron," respectively. He adds that "Although agreements were made between Tibetan leaders and Mongol khans, Ming and Qing emperors, it was the Republic of China and its Communist successors that assumed the former imperial tributaries and subject states as integral parts of the Chinese nation-state."
Document 5: Yin Yin Nwe: Yin Yin Nwe's father is Sao Saimong Mangrai, a member of the princely Kengtung State and a highly regarded scholar on Shan State and the Head of the Shan State Education Department during the post-Independence years. Yin Yin Nwe's mother is Mi Mi Khaing, also a scholar and a former Principal of Kambawza School. Her father, Sao Saimong, had an administrative career after the Shan principalities agreed to become part of the Union of Burma, and was Chief Education Officer for Shan and Kayah States. Her mother was the author of "Burmese Family", a book on Burmese culture and was one of the first women to write in English about Burmese culture and traditions. Yin Yin Nwe is of Mon ancestry on her mother's side and of Tai ancestry on her father's side, given that the state of Kengtung originated in the 13th century, when the Chiang Mai dynasty founded a new kingdom which was named Lanna, sending a prince to Kengtung to establish a separate kingdom.
Document 6: Our Films, Their Films: Our Films, Their Films is an anthology of film criticism by noted Bengali filmmaker, composer and writer Satyajit Ray. Collecting articles and personal journal excerpts, it was first published in India in 1976; an English translation was published in The United States and United Kingdom in 1992. Some of articles were previously published in the bulletin of the Calcutta Film Society which Ray co-founded in 1947.
Document 7: Sino-Tibetan relations during the Ming dynasty: The late Turrell V. Wylie, a former professor of the University of Washington, and Li Tieh-tseng argue that the reliability of the heavily censored History of Ming as a credible source on Sino-Tibetan relations is questionable, in the light of modern scholarship. Other historians also assert that these Ming titles were nominal and did not actually confer the authority that the earlier Yuan titles had. Van Praag writes that the "numerous economically motivated Tibetan missions to the Ming Court are referred to as 'tributary missions' in the Ming Shih." Van Praag writes that these "tributary missions" were simply prompted by China's need for horses from Tibet, since a viable horse market in Mongol lands was closed as a result of incessant conflict. Morris Rossabi also writes that "Tibet, which had extensive contacts with China during the Yuan, scarcely had diplomatic relations with the Ming."
Document 8: Sikkim (film): Sikkim is a 1971 Indian documentary about the nation of Sikkim, directed by Satyajit Ray. The documentary was commissioned by the Chogyal (King) of Sikkim at a time when he felt the sovereignty of Sikkim was under threat from both China and India. Ray's documentary is about the sovereignty of Sikkim. The film was banned by the government of India, when Sikkim merged with India in 1975. In 2000, the copyright of the film was transferred to the Art and Culture Trust of Sikkim. The ban was finally lifted by the Ministry of External Affairs (MEA) in September 2010. In November 2010 the director of the Kolkata film festival stated that upon screening the documentary for the first time, he received an injunction from the court of Sikkim again banning the film.
Document 9: Gangtok: Gangtok rose to prominence as a popular Buddhist pilgrimage site after the construction of the Enchey Monastery in 1840. In 1894, the ruling Sikkimese Chogyal, Thutob Namgyal, transferred the capital to Gangtok. In the early 20th century, Gangtok became a major stopover on the trade route between Lhasa in Tibet and cities such as Kolkata (then Calcutta) in British India. After India won its independence from Britain in 1947, Sikkim chose to remain an independent monarchy, with Gangtok as its capital. In 1975, after the integration with the union of India, Gangtok was made India's 22nd state capital.
Document 10: Mrinal Sen: After making five more films, he made a film with a shoestring budget provided by the Government of India. This film, Bhuvan Shome (Mr. Shome, 1969), finally launched him as a major filmmaker, both nationally and internationally. Bhuvan Shome also initiated the "New Cinema" film movement in India.
Document 11: Sikkim: In 1975, the Prime Minister of Sikkim appealed to the Indian Parliament for Sikkim to become a state of India. In April of that year, the Indian Army took over the city of Gangtok and disarmed the Chogyal's palace guards. Thereafter, a referendum was held in which 97.5 per cent of voters supported abolishing the monarchy, effectively approving union with India. India is said to have stationed 20,000 -- 40,000 troops in a country of only 200,000 during the referendum. On 16 May 1975, Sikkim became the 22nd state of the Indian Union, and the monarchy was abolished. To enable the incorporation of the new state, the Indian Parliament amended the Indian Constitution. First, the 35th Amendment laid down a set of conditions that made Sikkim an ``Associate State '', a special designation not used by any other state. A month later, the 36th Amendment repealed the 35th Amendment, and made Sikkim a full state, adding its name to the First Schedule of the Constitution.

Document 14: Sukumar Ray (film): Sukumar Ray is a 1987 Bengali short documentary film made by Satyajit Ray on his father, Sukumar Ray. It was released during the birth centenary year of Sukumar Ray, who was born on 30 October 1887. The thirty minutes documentary features the life and some of the works by Sukumar Ray in the form of paintings, photographs and readings. This is the last documentary made by Satyajit Ray as a tribute to his father, before he died in 1992. The documentary used Sukumar Ray's photographs and paintings than video recording as the film was considerably a new medium in India when Sukumar Ray died in 1923.
Document 15: Sino-Tibetan relations during the Ming dynasty: However, Lok-Ham Chan, a professor of history at the University of Washington, writes that Changchub Gyaltsen's aims were to recreate the old Tibetan Kingdom that existed during the Chinese Tang dynasty, to build "nationalist sentiment" amongst Tibetans, and to "remove all traces of Mongol suzerainty." Georges Dreyfus, a professor of religion at Williams College, writes that it was Changchub Gyaltsen who adopted the old administrative system of Songtsän Gampo (c. 605–649)—the first leader of the Tibetan Empire to establish Tibet as a strong power—by reinstating its legal code of punishments and administrative units. For example, instead of the 13 governorships established by the Mongol Sakya viceroy, Changchub Gyaltsen divided Central Tibet into districts (dzong) with district heads (dzong dpon) who had to conform to old rituals and wear clothing styles of old Imperial Tibet. Van Praag asserts that Changchub Gyaltsen's ambitions were to "restore to Tibet the glories of its Imperial Age" by reinstating secular administration, promoting "national culture and traditions," and installing a law code that survived into the 20th century.
