Toponymy

The origin theory of the name Sikkim is that it is a combination of two Limbu words: su, which means "new", and khyim, which means "palace" or "house".The Tibetan name for Sikkim is Drenjong , which means "valley of rice", while the Bhutias call it Beyul Demazong, which means '"the hidden valley of rice". According to folklore, after establishing Rabdentse as his new capital, Bhutia king Tensung Namgyal built a palace and asked his Limbu Queen to name it. The Lepcha people, the original inhabitants of Sikkim, called it Nye-mae-el, meaning "paradise". In historical Indian literature, Sikkim is known as Indrakil, the garden of the war god Indra.

History

The Lepchas are considered to be the earliest inhabitants of Sikkim. However the Limbus and the Magars also lived in the inaccessible parts of West and South districts as early as the Lepchas perhaps lived in the East and North districts. The Buddhist saint Padmasambhava, also known as Guru Rinpoche, is said to have passed through the land in the 8th century. 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 Tibetan people, 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.

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.

Prior to Indian independence, Jawaharlal Nehru, as the Vice President of the Executive Council, pushed through a resolution in the Indian Constituent Assembly to the effect that Sikkim and Bhutan, as Himalayan states, were not 'Indian states' and their future should be negotiated separately. A standstill agreement was signed in February 1948.

Meanwhile, Indian independence and its move to democracy spurred a fledgling political movement in Sikkim, giving rise to the formation of Sikkim State Congress (SSC), a pro-accession political party. The party sent a plate of demands to the palace, including a demand for accession to India. The palace attempted to defuse the movement by appointing three secretaries from the SSC to the government and sponsoring a counter-movement in the name of Sikkim National Party, which opposed accession to 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. 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.

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, in return for India declaring Tibet as a "part of" the territory of China; New Delhi had accepted Tibet as part of China way back in 1954, but China appears to have believed that the agreement had lapsed. The 2003 agreement led to a thaw in Sino-Indian relations. 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 was first opened during the 1904 Younghusband Expedition to Tibet, had remained closed since the 1962 Sino-Indian War.

Situated in the Himalayan mountains, the state of Sikkim is characterised by mountainous terrain. Almost the entire state is hilly, with an elevation ranging from 280 metres (920 ft) in the south at the border with West Bengal to 8,586 metres (28,169 ft) in northern peaks near Nepal and Tibet. The summit of Kangchenjunga, the world's third-highest peak, is the state's highest point, situated on the border between Sikkim and Nepal. For the most part, the land is unfit for agriculture because of the rocky, precipitous slopes. However, some hill slopes have been converted into terrace farms.

The hills of Sikkim mainly consist of gneiss and schist which weather to produce generally poor and shallow brown clay soils. The soil is coarse, with large concentrations of iron oxide; it ranges from neutral to acidic and is lacking in organic and mineral nutrients. This type of soil tends to support evergreen and deciduous forests.

The rock consists of phyllites and schists, and is highly susceptible to weathering and erosion. This, combined with the state's heavy rainfall, causes extensive soil erosion and the loss of soil nutrients through leaching. As a result, landslides are frequent, often isolating rural towns and villages from the major urban centres.

The state has five seasons: winter, summer, spring, autumn, and monsoon season. Sikkim's climate ranges from sub-tropical in the south to tundra in the north. Most of the inhabited regions of Sikkim experience a temperate climate, with temperatures seldom exceeding 28 °C (82 °F) in summer. The average annual temperature for most of Sikkim is around 18 °C (64 °F).

Sikkim is situated in an ecological hotspot of the lower Himalayas, one of only three among the ecoregions of India. The forested regions of the state exhibit a diverse range of fauna and flora. Owing to its altitudinal gradation, the state has a wide variety of plants, from tropical species to temperate, alpine and tundra ones, and is perhaps one of the few regions to exhibit such a diversity within such a small area. Nearly 81 per cent of the area of Sikkim comes under the administration of its forest department.

Sikkim is home to around 5,000 species of flowering plants, 515 rare orchids, 60 primula species, 36 rhododendron species, 11 oak varieties, 23 bamboo varieties, 16 conifer species, 362 types of ferns and ferns allies, 8 tree ferns, and over 900 medicinal plants. A relative of the Poinsettia, locally known as "Christmas Flower", can be found in abundance in the mountainous state. The Noble Dendrobium is the official flower of Sikkim, while the rhododendron is the state tree.

Sikkim's nominal state gross domestic product (GDP) was estimated at US$4.6 billion in 2019, with GDP per capita being $7,530 (₹ 5,50,000) thus constituting the third-smallest GDP among India's 28 states. The state's economy is largely agrarian based on the terraced farming of rice and the cultivation of crops such as maize, millet, wheat, barley, oranges, tea, and cardamom. Sikkim produces more cardamom than any other Indian state and is home to the largest cultivated area of cardamom.

The official languages of the state are English, Sikkimese Nepali, Sikkimese (Bhutia) and Lepcha. Additional official languages include Gurung, Limbu, Magar, Mukhia, Newar, Rai, Sherpa and Tamang for the purpose of preservation of culture and tradition in the state.

Nepali is the lingua franca of Sikkim, while Sikkimese (Bhutia) and Lepcha are spoken in certain areas. English is also spoken and understood in most of Sikkim. Other languages include Dzongkha, Groma, Hindi, Majhi, Majhwar, Thulung, Tibetan, and Yakha.

According to the 2011 census, 57.8% follow Hinduism, making it the state's majority religion. Buddhism is followed by 27.4% of the population, while Christianity is followed by 9.9%.Between 2001 and 2011, Christianity was the fastest growing religion in the state, going from 6.67% to 9.91% of the population. It was thus the fourth state with the highest Christian growth in the period, behind only Arunachal Pradesh, Manipur and Meghalaya. As of 2014, the Evangelical Presbyterian Church of Sikkim is the largest Christian denomination in Sikkim. Hinduism, on the other hand, declined from 60.93% to 57.76% of the population in the same period. Sikkim was the fourth state with the biggest decline in the percentage of Hindus, behind only Arunachal Pradesh, Manipur and Assam.
