West Bengal is a state in the eastern region of India, situated along the Bay of Bengal. It is bordered by the Indian states of Odisha, Jharkhand, Bihar, Sikkim, and Assam, and shares international boundaries with Bangladesh to the east, Nepal to the north-west, and Bhutan to the north. The capital city is Kolkata, which is also the state's largest urban centre and one of India's principal metropolises. The state was formed on 15 August 1947 following the partition of the Bengal Presidency, when the Hindu-majority western districts were retained in India while the eastern districts became East Pakistan (later Bangladesh).

Geography
West Bengal stretches from the Himalayas in the north to the Bay of Bengal in the south, encompassing a wide range of physiographic zones. The northern districts include the Darjeeling Himalayas and the Terai–Dooars belt; central and western parts comprise the Chota Nagpur plateau fringe and the Rarh region; the south is dominated by the Ganga–Brahmaputra delta, including the Sundarbans mangrove forest, a UNESCO World Heritage Site shared with Bangladesh. The Hooghly, a distributary of the Ganga, flows through Kolkata and is central to the state's commerce and culture.
Administrative divisions
The state is organised into administrative divisions and districts, each headed by a District Magistrate. Districts are further subdivided into subdivisions, blocks, and gram panchayats in rural areas, and into municipalities and municipal corporations in urban areas. Kolkata, Howrah, Asansol, Siliguri, and Durgapur are among the principal urban centres.
History
The territory of present-day West Bengal has been part of successive historical polities, including the Maurya, Gupta, Pala, and Sena empires, and later the Delhi Sultanate, the Bengal Sultanate, and the Mughal Empire. Bengal came under the influence of the British East India Company after the Battle of Plassey in 1757 and the Battle of Buxar in 1764. Calcutta served as the capital of British India until 1911. The 1905 partition of Bengal by Lord Curzon, and its annulment in 1911, were significant episodes in the freedom movement. After independence in 1947, Bengal was partitioned along religious lines, and the Indian portion became the state of West Bengal. The States Reorganisation Act of 1956 transferred parts of Bihar, including Purulia, to West Bengal.
Economy
The economy of West Bengal is diversified, with significant contributions from agriculture, manufacturing, services, and trade. The state is among India's largest producers of rice, jute, potatoes, and tea, with Darjeeling tea holding a Geographical Indication tag. Industrial activity is concentrated in the Hooghly industrial belt, Asansol–Durgapur (steel, coal, and engineering), and Haldia (petrochemicals and port-based industries). The Port of Kolkata, officially the Syama Prasad Mookerjee Port, is one of India's major ports.
Transport
West Bengal is served by an extensive rail network operated primarily by Eastern Railway and South Eastern Railway, with the headquarters of Eastern Railway at Kolkata. The Kolkata Metro, inaugurated in 1984, was India's first metro rail system. Several national highways traverse the state, including NH 12, NH 16, NH 19, and NH 27. Major airports include Netaji Subhas Chandra Bose International Airport in Kolkata and Bagdogra Airport near Siliguri. Smaller stations such as Basuldanga railway station form part of the dense suburban and regional rail network.
Culture
Bengali culture has produced significant figures in literature, music, cinema, science, and social reform, including Rabindranath Tagore, the first non-European Nobel laureate in Literature (1913); Bankim Chandra Chattopadhyay; Kazi Nazrul Islam; Satyajit Ray; Jagadish Chandra Bose; Meghnad Saha; and Amartya Sen. Major festivals include Durga Puja, inscribed on the UNESCO Representative List of the Intangible Cultural Heritage of Humanity in 2021, along with Kali Puja, Poila Boishakh, Saraswati Puja, Eid, and Christmas.
Significance
West Bengal occupies a strategic position in eastern India as a gateway to the North-East, Bangladesh, Bhutan, and Nepal. Kolkata's role as a former imperial capital, a centre of the Bengal Renaissance, and a hub of trade and education continues to shape the state's cultural and economic prominence.
