Kolkata

Kolkata (Bengali: কলকাতা / কোলকাতা) /koʊlˈkɑːtɑː/, formerly Calcutta /kælˈkʌtə/, is the capital of the Indian state of West Bengal. Located on the east bank of the Hooghly river, it is the principal commercial, cultural, and educational centre of East India, while the Port of Kolkata is India's oldest operating port and its sole major riverine port. As of 2011, the city had 4.5 million residents; the urban agglomeration, which comprises the city and its suburbs, was home to approximately 14.1 million, making it the third-most populous metropolitan area in India. As of 2008, its gross domestic product (adjusted for purchasing power parity) was estimated to be US$104 billion, which would be third highest among Indian cities, behind Mumbai and Delhi. As a growing metropolitan city in a developing country, Kolkata confronts substantial urban pollution, traffic congestion, poverty, overpopulation, and other logistic and socioeconomic problems.

West Bengal

West Bengal (/wɛst bɛŋˈɡɔːl/; Bengali pronunciation: [pɔʃtʃimbɔŋɡɔ]) is a state in eastern India and is the nation's fourth-most populous state, with over 91 million inhabitants. Spread over 34,267 sq mi (88,750 km²), it is bordered by the countries of Bangladesh, Nepal and Bhutan, and the Indian states of Odisha, Jharkhand, Bihar, Sikkim, and Assam. The state capital is Kolkata. Together with the neighboring nation of Bangladesh, it makes up the ethno-linguistic region of Bengal.

Ancient Bengal was the site of several major janapadas (kingdoms). It was also part of large empires such as the Maurya Empire (second century BC) and Gupta Empire (fourth century AD); and part of the regional Buddhist Pala Empire (8th to 11th century) and Sena dynasty (11th–12th century). From the 13th century onward, the region was controlled by the Bengal Sultanate, Hindu kings and Baro-Bhuyan landlords under the suzerainty of the Mughal Empire, until the British East India company took control of the region from the Mughals in the late 18th century. The company consolidated their hold on the region following the Battle of Plassey in 1757 and Battle of Buxar in 1764 and by 1793 took complete control of the region. Kolkata (or Calcutta) served for many years as the capital of British controlled territories in India. The early and prolonged exposure to British administration resulted in the expansion of Western education, culminating in development of science, institutional education, and social reforms in the region, including what became known as the Bengali renaissance. A hotbed of the Indian independence movement through the early 20th century, Bengal was divided during India's independence in 1947 along religious lines into two separate entities: West Bengal—a state of India—and East Bengal—a part of the newly created Dominion of Pakistan that later became the independent nation of Bangladesh in 1971.

India

India, officially the Republic of India (Bhārat Gaṇarājya), is a country in South Asia. It is the seventh-largest country by area, the second-most populous country with over 1.2 billion people, and the most populous democracy in the world. Bounded by the Indian Ocean on the south, the Arabian Sea on the south-west, and the Bay of Bengal on the south-east, it shares land borders with Pakistan to the west;China, Nepal, and Bhutan to the north-east; and Myanmar (Burma) and Bangladesh to the east. In the Indian Ocean, India is in the vicinity of Sri Lanka and the Maldives; in addition, India's Andaman and Nicobar Islands share a maritime border with Thailand and Indonesia.

Home to the ancient Indus Valley Civilisation and a region of historic trade routes and vast empires, the Indian subcontinent was identified with its commercial and cultural wealth for much of its long history. Four religions—Hinduism, Buddhism, Jainism, and Sikhism—originated here, whereas Zoroastrianism, Judaism, Christianity, and Islam arrived in the 1st millennium CE and also shaped the region's diverse culture. Gradually annexed by and brought under the administration of the British East India Company from the early 18th century and administered directly by the United Kingdom after the Indian Rebellion of 1857, India became an independent nation in 1947 after a struggle for independence that was marked by non-violent resistance led by Mahatma Gandhi.

East India

East India is a region of India consisting of the Indian states of West Bengal,Bihar,Jharkhand, Odisha and also the union territory Andaman and Nicobar Islands. West Bengal's capital Kolkata is the largest city of this region. The Kolkata Metropolitan Area is the country's third largest. The states of Odisha and West Bengal share some cultural and linguistic characteristics with Bangladesh and with the state of Assam.. Bengali is the most spoken language of this region and it is also the second most spoken language in India after Hindi. Odia is the only language in east India accorded the status of a Classical Language of India. Together with Bangladesh, West Bengal formed the ethno-linguistic region of Bengal before partition in 1947. The historic region of Bengal which was ruled by Nawabs of Bengal comprises the present, West Bengal, Bihar, Jharkhand and Bangladesh from where the British started their conquest of India. Modern days Odisha in ancient time know as Kalinga, Utkala and ruled by indigenous mighty rulers of Mahameghavahana dynasty, Eastern Ganga dynasty and Gajapati Dynasty.

Howrah Bridge

Howrah Bridge is a cantilever bridge with a suspended span over the Hooghly River in West Bengal, India. Commissioned in 1943, the bridge was originally named the New Howrah Bridge, because it replaced a pontoon bridge at the same location linking the two cities of Howrah and Kolkata (Calcutta). On 14 June 1965 it was renamed Rabindra Setu after the great Bengali poet Rabindranath Tagore, who was the first Indian and Asian Nobel laureate. It is still popularly known as the Howrah Bridge.

The bridge is one of two on the Hooghly River and is a famous symbol of Kolkata and West Bengal. The other bridges are the Vidyasagar Setu (popularly called the Second Hooghly Bridge), the Vivekananda Setu, and the newly built Nivedita Setu. It weathers the storms of the Bay of Bengal region, carrying a daily traffic of approximately 100,000 vehicles and possibly more than 150,000 pedestrians, easily making it the busiest cantilever bridge in the world. The third-longest cantilever bridge at the time of its construction, the Howrah Bridge is the sixth-longest bridge of its type in the world.
