Etymology

The word ''Kolkata'' ( ) derives from '' Kôlikata'' ( ), the Bengali language name of one of three villages that predated the arrival of the British; the other two villages were Sutanuti and Govindapur. There are several explanations for the etymology of this name: * ''Kolikata'' is thought to be a variation of ''Kalikkhetrô'' ( ), meaning 'Field of he goddess Kali'. Similarly, it can be a variation of ''Kalikshetra'' (
Sanskrit Sanskrit (; stem form ; nominal singular , ,) is a classical language belonging to the Indo-Aryan languages, Indo-Aryan branch of the Indo-European languages. It arose in northwest South Asia after its predecessor languages had Trans-cultural ...
: कालीक्षेत्र, lit. 'area of Goddess Kali'). * Another theory is that the name derives from Kalighat. * Alternatively, the name may have been derived from the Bengali term ''kilkila'' (), or 'flat area'. * The name may have its origin in the words ''khal'' ( ) meaning 'canal', followed by ''kaṭa'' ( ), which may mean 'dug'. * According to another theory, the area specialised in the production of quicklime or ''koli chun'' ( ) and coir or ''kata'' ( ); hence, it was called ''Kolikata''). Although the city's name has always been pronounced ''Kolkata'' or ''Kôlikata'' in Bengali, the anglicised form ''Calcutta'' was the official name until 2001, when it was changed to ''Kolkata'' in order to match Bengali pronunciation. Both English variants are used.


History

The discovery and archaeological study of Chandraketugarh, north of Kolkata, provide evidence that the region in which the city stands has been inhabited for over two millennia. Kolkata or Kalikata in its earliest mentions, is described to be a village surrounded with jungle on the bank of river Ganga as a renowned port, commercial hub and a Hindu pilgrimage site for Kalighat Temple. The first mention of the Kalikata village was found in Bipradas Pipilai's ''Manasa Vijay'' (1495), where he describes how Chand Sadagar used to stop in Kalighat to worship Goddess Kali during his path to trade voyage. Later Kalikata was also found to be mentioned in Mukundaram Chakrabarti's '' Chandimangal'' (1594), Todar Mal's taxation-list in 1596 and Krishnaram Das's ''Kalikamangal'' (1676–77). Kalighat was then considered a safe place for businessmen. They used to carry on trade through the Bhagirathi and took shelter there at night. Kolkata's

, which was consolidating its trade business in Bengal. Job Charnock is often regarded as the founder of the city; however, in response to a public petition, the Calcutta High Court ruled in 2003 that the city does not have a founder. The area occupied by the present-day city encompassed three villages: Kalikata, Gobindapur and Sutanuti. Kalikata was a fishing village, where a handful of merchants began their operations by building a factory; Sutanuti was a riverside weavers' village; and Gobindapur was a trading post for Indian merchant princes. These villages were part of an estate belonging to the Sabarna Roy Choudhury family of '' zamindars''. The estate was sold to the East India Company in 1698. In 1712, the British completed the construction of Fort William, located on the east bank of the Hooghly River to protect their trading factory. Facing frequent skirmishes with French forces, the British began to upgrade their fortifications in 1756. The Nawab of Bengal, Siraj-ud-Daulah, condemned the militarisation and tax evasion by the company. His warning went unheeded, and the Nawab attacked; his capture of Fort William led to the killings of several East India company officials in the Black Hole of Calcutta. A force of Company soldiers ('' sepoys'') and British troops led by Robert Clive recaptured the city the following year. Per the 1765 Treaty of Allahabad following the battle of Buxar, East India company was appointed imperial tax collector of the Mughal emperor in the province of Bengal, Bihar and Orissa, while Mughal-appointed Nawabs continued to rule the province. Declared a presidency city, Calcutta became the headquarters of the East India Company by 1773. In 1793, ruling power of the Nawabs were abolished, and East India company took complete control of the city and the province. In the early 19th century, the marshes surrounding the city were drained; the government area was laid out along the banks of the Hooghly River. Richard Wellesley, Governor-General of the Presidency of Fort William between 1797 and 1805, was largely responsible for the development of the city and its public architecture. Throughout the late 18th and 19th century, the city was a centre of the East India Company's opium trade. A census in 1837 records the population of the city proper as 229,700, of which the British residents made up only 3,138. The same source says another 177,000 resided in the suburbs and neighbouring villages, making the entire population of greater Calcutta 406,700. In 1864, a typhoon struck the city and killed about 60,000 in Kolkata. By the 1850s, Calcutta had two areas: White Town, which was primarily British and centred on Chowringhee and Dalhousie Square; and Black Town, mainly Indian and centred on North Calcutta. The city underwent rapid industrial growth starting in the early 1850s, especially in the textile and jute industries; this encouraged British companies to massively invest in infrastructure projects, which included telegraph connections and . The coalescence of British and Indian culture resulted in the emergence of a new '' babu'' class of urbane Indians, whose members were often bureaucrats, professionals, newspaper readers, and Anglophiles; they usually belonged to upper-caste Hindu communities. In the 19th century, the Bengal Renaissance brought about an increased sociocultural sophistication among city denizens. In 1883, Calcutta was host to the first national conference of the Indian National Association, which was the first avowed nationalist organisation in India. The partition of Bengal in 1905 along religious lines led to mass protests, making Calcutta a less hospitable place for the British. The capital was moved to New Delhi in 1911. Calcutta continued to be a centre for revolutionary organisations associated with the

In the 2011 West Bengal Legislative Assembly election, Left Front was succeeded by the Trinamool Congress.

Environmental issues

Pollution is a major concern in Kolkata. , sulphur dioxide and nitrogen dioxide annual concentration were within the national ambient air quality standards of India, but respirable suspended particulate matter levels were high, and on an increasing trend for five consecutive years, causing smog and haze.

and home to the Calcutta Stock Exchange. It is a major commercial and military port, and is one of five cities in eastern India (alongside Bhubaneswar, Guwahati, Imphal, and Kushinagar) to have an international airport. Once India's leading city, Kolkata experienced a steady economic decline in the decades following India's independence due to steep population increases and a rise in militant trade-unionism, which included frequent strikes that were backed by left-wing parties. From the 1960s to the late 1990s, several factories were closed and businesses relocated. The lack of capital and resources added to the depressed state of the city's economy and gave rise to an unwelcome sobriquet: the "dying city". The city's fortunes improved after the Indian economy was liberalised in the 1990s and changes in economic policy were enacted by the West Bengal state government. Recent estimates of the economy of Kolkata's metropolitan area have ranged from $150 to $250 billion ( PPP GDP), and have ranked it third-most productive metro area of India.

Flexible production has been the norm in Kolkata, which has an informal sector that employs more than 40% of the labour force. One unorganised group, roadside hawkers, generated business worth in 2005. , around 0.81% of the city's workforce was employed in the primary sector (agriculture, forestry, mining, etc.); 15.49% worked in the secondary sector (industrial and manufacturing); and 83.69% worked in the tertiary sector (service industries). , the majority of households in slums were engaged in occupations belonging to the informal sector; 36.5% were involved in servicing the urban middle class (as maids, drivers, etc.) and 22.2% were casual labourers. About 34% of the available labour force in Kolkata slums were unemployed. According to one estimate, almost a quarter of the population live on less than per day. Major manufacturing companies in the city are Alstom, Larsen & Toubro, Fosroc, Videocon. As in many other Indian cities, information technology became a high-growth sector in Kolkata starting in the late 1990s; the city's IT sector grew at 70% per annum—a rate that was twice the national average. The 2000s saw a surge of investments in the real estate, infrastructure, retail, and hospitality sectors; several large shopping malls and hotels were launched. Companies such as ITC Limited, CESC Limited, Exide Industries, Emami, Eveready Industries India, Lux Industries, Rupa Company, Berger Paints, Birla Corporation, Britannia Industries and Purushottam Publishers are headquartered in the city. Philips India, PwC India, Tata Global Beverages, and Tata Steel have their registered office and zonal headquarters in Kolkata.

for residents of Kolkata are ''Calcuttan'' and ''Kolkatan''. According to provisional results of the 2011 national census, Kolkata district, which occupies an area of , had a population of 4,486,679; its population density was . This represents a decline of 1.88% during the decade 2001–11. The sex ratio is 899 females per 1000 males—lower than the national average. The ratio is depressed by the influx of working males from surrounding rural areas, from the rest of West Bengal; these men commonly leave their families behind. Kolkata's literacy rate of 87.14% exceeds the national average of 74%. The final population totals of census 2011 stated the population of city as 4,496,694. The urban agglomeration had a population of 14,112,536 in 2011. , about one-third of the population, or 15 lakh (1.5 million) people, lived in 3,500 unregistered squatter-occupied and 2,011 registered slums. The authorised slums (with access to basic services like water, latrines, trash removal by the Kolkata Municipal Corporation) can be broadly divided into two groups—''bustees'', in which slum dwellers have some long term tenancy agreement with the landowners; and ''udbastu colonies'', settlements which had been leased to refugees from present-day Bangladesh by the government. The unauthorised slums (devoid of basic services provided by the municipality) are occupied by squatters who started living on encroached lands—mainly along canals, railway lines and roads. According to the 2005 National Family Health Survey, around 14% of the households in Kolkata were poor, while 33% lived in slums, indicating a substantial proportion of households in slum areas were better off economically than the bottom quarter of urban households in terms of wealth status.

The agency overseeing the latter, the Kolkata Metropolitan Development Authority, is responsible for the statutory planning and development of greater Kolkata. The Kolkata Municipal Corporation was ranked first out of 21 cities for best governance and administrative practices in India in 2014. It scored 4.0 on 10 compared to the national average of 3.3.

To promote the recycling of garbage and sewer water, agriculture is encouraged on the dumping grounds. Parts of the city lack proper sewerage, leading to unsanitary methods of waste disposal. In 1856, the Bengal Government appointed George Turnbull to be the Commissioner of Drainage and Sewerage to improve the city's sewerage. Turnbull's main job was to be the Chief Engineer of the East Indian Railway Company responsible for building the first railway from Howrah to Varanasi (then
