Bengal (Bengali: বঙ্গ; romanised: Bongo) is a cultural and historic region in South Asia. It is situated at the apex of the Bay of Bengal. On the north, it is bounded by the Himalayas; on the west by the Plains of India; on the east by North-Eastern India; and on the southeast by Myanmar (Burma). Today most of the region is divided into the Indian state of West Bengal and the separate nation of Bangladesh, but in some contexts the term "Bengal" includes other areas for historical or cultural reasons. In Indian usage, the term "Bengal" often refers exclusively to West Bengal.
The most important cities of Bangladesh are the capital Dhaka and the historic port Chittagong. On the Indian side, Kolkata (Calcutta) is both the state capital and the main port. Major tourist areas include the picturesque hill station Darjeeling in West Bengal and the beach resort town of Cox's Bazar in Bangladesh. The Sundarbans are a UNESCO World Heritage Site that spans the border with national parks on both sides; the area includes the world's largest mangrove swamp and is home to the Bengal tiger.
Most of Bengal is in the enormous delta area formed by a complex of three rivers.
The Ganges flows roughly west-to-east across much of northern India, and is historically the country's most important river. The Brahmaputra is the greatest river of northeast India, and both it and the Meghna are important in Bangladesh. By the time they reach the sea, the combined rivers (called the Padma in this region) are the world's third largest by volume of water discharged. The Brahmaputra, considered by itself, ranks eighth.
At times political units called "Bengal" extended into nearby areas which were not ethnically or linguistically Bengali. When the British defeated the last Nawab of Bengal and his French allies at the Battle of Plassey in 1757, they took not only Bengal itself but also the Nawab's other territories, now the states of Bihar, Orissa and Jharkhand. Under the British, what is now Assam was administered as part of the Bengal Presidency.
When the territory of the British Raj was partitioned in 1947, the two new states India and Pakistan each got part of Bengal. Later East Pakistan (the Bengali part) broke away from the rest of Pakistan to become the separate nation of Bangladesh.
As anywhere in the subcontinent English is quite widely spoken, but mainly in urban areas and among the educated classes.
