Sikkim (; also known as Shikim or Su Khyim; see Toponymy for other names) is a landlocked Indian state located in the Himalayan mountains. The state is bordered by Nepal to the west, China's Tibet Autonomous Region to the north and east, and Bhutan to the east. The Indian state of West Bengal lies to the south.
With 610,577 inhabitants as of the 2011 census, Sikkim is the least populous state in India and the second-smallest state after Goa in total area, covering approximately . Sikkim is nonetheless geographically diverse due to its location in the Himalayas; the climate ranges from subtropical to high alpine, and Kangchenjunga, the world's third-highest peak, is located on Sikkim's border with Nepal. Sikkim is a popular tourist destination, owing to its culture, scenery and biodiversity. It also has the only open land border between India and China. Sikkim's capital and largest city is Gangtok.
According to legend, the Buddhist guru Padmasambhava visited Sikkim in the 8th century AD, introduced Buddhism and foretold the era of the Sikkimese monarchy. Sikkim's Namgyal dynasty was established in 1642. Over the next 150 years, the kingdom witnessed frequent raids and territorial losses to Nepalese invaders. In the 19th century, it allied itself with British India, eventually becoming a British protectorate. In 1975, a referendum abolished the Sikkimese monarchy, and the territory was merged with India.
Sikkim has 11 official languages: Nepali (which is its lingua franca), Sikkimese, Lepcha, Tamang, Limbu, Newari, Rai, Gurung, Magar, Sunwar and English. English is taught in schools and used in government documents. The predominant religions are Hinduism and Vajrayana Buddhism. Sikkim's economy is largely dependent on agriculture and tourism, and the state had the third-smallest GDP among Indian states, although it is also among the fastest-growing.
Founding of the monarchy
Little is known about Sikkim's ancient history, beyond the fact that its original inhabitants were the Lepcha. The earliest historical mention of Sikkim is a record of the passage of the Buddhist saint Padmasambhava, also known as Guru Rinpoche, through the land in the 8th century AD. The Guru is reported to have blessed the land, introduced Buddhism, and foretold the era of monarchy that would arrive in Sikkim centuries later. According to legend, Khye Bumsa, a 14th-century prince from the Minyak House in Kham in eastern Tibet, received a divine revelation instructing him to travel south to seek his fortunes. A fifth-generation descendant of Khye Bumsa, Phuntsog Namgyal, became the founder of Sikkim's monarchy in 1642, when he was consecrated as the first Chogyal, or priest-king, of Sikkim by the three venerated lamas at Yuksom.
Phuntsog Namgyal was succeeded in 1670 by his son, Tensung Namgyal, who moved the capital from Yuksom to Rabdentse. 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.
Sikkim during the British Raj
Following the beginning of British rule in neighbouring India, Sikkim allied with Britain against their common adversary, Nepal. The Nepalese attacked Sikkim, overrunning most of the region including the Terai. This prompted the British East India Company to attack Nepal, resulting in the Gurkha War of 1814. Treaties signed between Sikkim and Nepal resulted in the return of the territory annexed by the Nepalese in 1817. However, ties between Sikkim and the British weakened when the latter began taxation of the Morang region. In 1849, two British physicians, Sir Joseph Dalton Hooker and Dr. Archibald Campbell, the latter being in charge of relations between the British and Sikkimese governments, ventured into the mountains of Sikkim unannounced and unauthorised. The doctors were detained by the Sikkimese government, leading to a punitive British expedition against the kingdom, after which the Darjeeling district and Morang were annexed to British India in 1853. The invasion led to the Chogyal of Sikkim becoming a titular ruler under the directive of the British governor. In 1890, Sikkim became a British protectorate, and was gradually granted more sovereignty over the next three decades.
After Indian independence
In 1947, when India became independent, a popular vote rejected Sikkim's joining the Indian Union. Although a treaty was made between India and Sikkim in 1950, in the interest of Prime Minister Jawaharlal Nehru . That Indo-Sikkim treaty made Sikkim an Indian protectorate status. Sikkim came under the suzerainty of India, which controlled its external affairs, defence, diplomacy and communications, but Sikkim otherwise retained administrative autonomy.
A state council was established in 1953 to allow for constitutional government under the Chogyal. Meanwhile, the Sikkim National Congress demanded fresh elections and greater representation for Nepalis in Sikkim. Palden Thondup Namgyal, the Chogyal at the time, proved to be extremely unpopular with the people, and in 1973, riots in front of the Chogyal's palace led to a formal request for protection from India.
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. Although the union was presented as the will of the people by the India authority, the merger was widely criticized as an annexation and India was accused of exploiting the ethnic divide and rigging 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. Later, the 36th Amendment repealed the 35th Amendment, and made Sikkim a full state, adding its name to the First Schedule of the Constitution.
In 2000, the seventeenth Karmapa, Urgyen Trinley Dorje, who had been confirmed by the Dalai Lama and accepted as a tulku by the Chinese government, escaped from Tibet, seeking to return to the Rumtek Monastery in Sikkim. Chinese officials were in a quandary on this issue, as any protests to India would mean an explicit endorsement of India's governance of Sikkim, which China still recognised as an independent state occupied by India. The Chinese government eventually recognised Sikkim as an Indian state in 2003, on the condition that India officially recognise Tibet as a part of China; New Delhi had originally accepted Tibet as a part of China in 1953 during the government of Jawaharlal Nehru. The 2003 agreement led to a thaw in Sino-Indian relations, and on 6 July 2006, the Sikkimese Himalayan pass of Nathu La was opened to cross-border trade, becoming the first open border between India and China. The pass, which had previously been closed since the 1962 Sino-Indian War, was an offshoot of the ancient Silk Road.
On 18 September 2011, a magnitude 6.9Mw earthquake struck Sikkim, killing at least 116 people in the state and in Nepal, Bhutan, Bangladesh and Tibet. More than 60 people died in Sikkim alone, and the city of Gangtok suffered significant damage.
