Bengal

• 1. Introduction

  ›

  Bengal stretches across the delta where the Ganges, Brahmaputra, and Meghna rivers meet the Bay of Bengal, and it carries within its soil the memory of civilisations that once deterred the army of Alexander the Great. In 325 BCE, word of a powerful kingdom in the Ganges delta reached Alexander's troops and stopped them in their tracks. The accounts described a people with a cavalry of war elephants so formidable that the conquerors turned back. The Greeks and Romans knew this land as Gangaridai. Roman coins bearing the image of Hercules have been found here, pointing to trade links with Roman Egypt through the Red Sea. A single Roman amphora, made in what is now the city of Aqaba in Jordan, was recovered from what we know today as Purba Medinipur district of West Bengal.

  With a population of roughly 300 million, the Bengali people form the third largest ethnic group in the world, after the Han Chinese and Arabs. The region today is divided between Bangladesh and the Indian state of West Bengal, yet that division is only the latest in a long series of partitions, conquests, and realignments that have shaped this land for more than three thousand years. How did a river delta become one of the wealthiest corners of the medieval world? Why did a majority of its people adopt the religion of their conquerors in a way that happened almost nowhere else in India? And what drove, in the summer of 1947, a last-ditch effort to keep Bengal united, and why did it fail? These are the questions at the heart of this story.

• 2. The Name and Its Roots

  ›

  The earliest records that mention Vanga, the kingdom whose name eventually became Bengal, appear in the Mahabharata epic, placing it in the first millennium BCE. The land of Vanga came to be called Vangala, and the oldest surviving written reference to that form appears in the Comilla copperplates of 720 CE, issued by a Buddhist Deva king named Ananda Deva, where he styled himself Sri Vangala Mriganka, meaning the moon of Bengal.

  The word also appears carved into the Brihadisvara Temple at Thanjavur, one of the oldest physical inscriptions connecting this distant southern monument to a northeastern region. By the 11th century, South Indian records were using the term Vangaladesa. An early 12th-century Sanskrit text, the Manasollasa, used the form Gaudabangala to describe the whole region.

  The modern form Bangla gained currency from the 14th century onward, when the Bengal Sultanate was founded. Its first ruler, Shamsuddin Ilyas Shah, carried the title Shah of Bangala. Arab geographers Ahmad ibn Majid and Sulaiman Al Mahri described the region as Bangala. Portuguese navigators, arriving in the Age of Discovery, wrote it as Bengala. Each visitor spelling the name in a new script was, in effect, recording the moment Bengal first entered their world.

• 3. Empires of the Delta

  ›

  Gopala I, the first Pala emperor, was not born to a throne. He was chosen by an assembly of chieftains in the ancient city of Gauda, an act of election rare in the history of South Asian kingship. The Pala Empire that followed grew into one of the largest empires in the subcontinent, reaching its greatest territorial extent under Dharmapala and Devapala. The Palas built the Somapura Mahavihara, the largest monastic institution in the subcontinent, and supported the university of Nalanda. Their influence extended as far as Tibet and Sumatra through the travels of a missionary named Atisa.

  Before the Palas, the region had passed through the Mauryan Empire, documented in the 3rd century BCE through the Mahasthan Brahmi Inscription, an administrative order about relief for a distressed population. Before that, Neolithic settlements dotted the delta; rice-cultivating communities appeared in the second millennium BCE; by the 11th century BCE, people in Bengal were living in aligned homes, crafting black and red pottery, and producing copper objects.

  The first unified Bengali polity belongs to a king named Shashanka, who founded the Gauda Kingdom and whose reign gave the Bengali calendar its starting point. After Shashanka died, the region entered a period of civil war that contemporaries called Matsyanyayam, meaning the law of fish, where the large devour the small. The Pala dynasty emerged from that chaos. When the Palas eventually declined, the Sena dynasty, a resurgent Hindu line, replaced them as the dominant power by the 11th century.

• 4. Conquest and Sultanate

  ›

  In 1204, the Ghurid general Muhammad bin Bakhtiyar Khalji swept into Bengal with a cavalry that historians would record as having entered the Bengali capital disguised as horse traders. Once inside the royal compound, Bakhtiyar and his horsemen overpowered the guards of the Sena king just as the king had sat down to eat. The king fled to the forest with his followers. This overthrow was described by one historical account as a coup d'etat that inaugurated an era lasting over five centuries in which most of Bengal was dominated by rulers professing Islam. The same account noted what was exceptional: only in Bengal, a region approximately the size of England and Scotland combined, did a majority of the indigenous population adopt the religion of the ruling class.

  Bengal became a province of the Delhi Sultanate, though Delhi struggled to maintain control given the enormous distance. Local governors repeatedly asserted autonomy. In 1338, governors in three towns, Lakhnauti, Satgaon, and Sonargaon, declared independence simultaneously. By 1352, Shamsuddin Ilyas Shah, the ruler of Satgaon, had unified the region into an independent state known as the Bengal Sultanate, with its capital in Pandua.

  At that moment, the Islamic world stretched from Muslim Spain in the west to Bengal in the east. Ilyas Shah's first raids sent the first Muslim army into Nepal and pushed westward to Varanasi and south to Orissa. His son Sikandar Shah later defeated Delhi Sultan Firuz Shah Tughluq at the Siege of Ekdala Fort, and received a golden crown from Delhi in a peace treaty that formally recognised Bengal's independence. Under Alauddin Hussain Shah, considered the Sultanate's greatest military leader, forces led by Shah Ismail Ghazi overthrew the Khen dynasty and annexed large parts of Assam. A giraffe brought by African envoys from Malindi arrived at the Bengal court and was subsequently gifted to Imperial China. Bengali ships were the largest vessels in the waters of the Malay Archipelago during the 15th century.

• 5. Paradise of the Nations

  ›

  The Mughal Emperors who absorbed Bengal into their empire gave the province a remarkable nickname: the Paradise of the Nations. The description was not flattery. Mughal Bengal had the richest elite and was the wealthiest province in the subcontinent. A new provincial capital was built at Dhaka, which became a centre of palace intrigue and politics. Governors of note included the Rajput general Man Singh I, Emperor Shah Jahan's son Prince Shah Shuja, and the aristocrat Shaista Khan, during whose tenure Portuguese and Arakanese traders were expelled from the port of Chittagong in 1666.

  Much of Bengal's wealth rested on muslin. The most important centre of cotton production in the Mughal era was Bengal, particularly around Dhaka, and muslin from this city was known simply as daka in markets as far away as Central Asia. Bengal accounted for 40% of Dutch imports from Asia, including more than 50% of textiles and around 80% of silks. From Bengal, saltpetre was shipped to Europe, opium was sold in Indonesia, raw silk was exported to Japan and the Netherlands, and cotton cloth reached the Americas and the Indian Ocean.

  Economic historian Indrajit Ray estimates the annual shipbuilding output of Bengal in the 16th-18th centuries at 223,250 tons, compared with just 23,061 tons produced across nineteen colonies in North America between 1769 and 1771. By the 18th century, the Nawab of Bengal had become a semi-independent figure, officially titled the Nawab of Bengal, Bihar and Orissa, issuing his own coins while pledging nominal allegiance to the Mughal emperor. The treasury of the Nawab was the biggest single source of revenue for the imperial court in Delhi. When the British East India Company defeated the last independent Nawab at the Battle of Plassey in 1757, it was not just a military victory. It was the capture of the economic engine of the subcontinent.

• 6. Colonial Transformation

  ›

  Calcutta was named the capital of British territories in India in 1772, and from there the Bengal Presidency expanded into the largest administrative unit of the British Empire. At its greatest extent, it covered large parts of present-day India, Pakistan, Bangladesh, Burma, Malaysia, and Singapore. Between 1830 and 1867, the ports of Singapore and Malacca, the island of Penang, and a portion of the Malay Peninsula all fell under its jurisdiction.

  The Bengal Presidency had the world's sixth earliest railway network. It was also the staging ground for the Indian Rebellion of 1857, which began on the outskirts of Calcutta and spread to Dhaka, Chittagong, Jalpaiguri, Sylhet, and Agartala. When the rebellion failed, Company Rule was abolished and direct Crown authority, the British Raj, took its place.

  The cost of colonial rule was heavy. The Great Bengal Famine of 1770, caused by a combination of economic mismanagement, drought, and a smallpox epidemic, is estimated to have caused the deaths of between one million and ten million people. The Bengal Famine of 1943 struck again during World War II. About 200,000 people were killed by the Great Backerganj Cyclone of 1876 in the Barisal region. Company policies deliberately dismantled Bengal's textile industry, and the capital extracted was invested in the Industrial Revolution in Britain.

  Yet the colonial period also produced the Bengal Renaissance of the late 19th and early 20th centuries, which modernised literature and science across the region. In 1911, the poet and polymath Rabindranath Tagore became Asia's first Nobel laureate, winning the Nobel Prize in Literature. The All-India Muslim League was established in Dhaka in 1906. Subhas Chandra Bose later led the Indian National Army against the British. In 1862, the Bengal Legislative Council was created as the first modern legislature in India.

• 7. The Partition and Its Aftermath

  ›

  On the 27th of April 1947, Huseyn Shaheed Suhrawardy, the last Prime Minister of Bengal, stood before a press conference in New Delhi and made the case for a united, independent Bengal. His words were direct: "Let us pause for a moment to consider what Bengal can be if it remains united. It will be a great country, indeed the richest and the most prosperous in India capable of giving to its people a high standard of living." He called it not a dream but a possibility.

  British Prime Minister Clement Attlee told the US Ambassador on the 2nd of June 1947 that there was a "distinct possibility Bengal might decide against partition and against joining either Hindustan or Pakistan". The following day, the Mountbatten Plan outlined the partition of British India.

  The votes that followed tell the story of a divided region. At the preliminary joint meeting of the Bengal Legislative Assembly on the 20th of June, legislators decided by 126 votes to 90 that if Bengal remained united it should join Pakistan. At a separate meeting of legislators from West Bengal, the vote was 58 to 21 in favour of partition and joining India. At another meeting of legislators from East Bengal, it was decided by 106 votes to 35 that the province should not be partitioned. The English barrister Cyril Radcliffe was instructed to draw the new borders. His Radcliffe Line awarded two-thirds of Bengal as the eastern wing of Pakistan, though the historic Bengali capitals of Gaur, Pandua, Murshidabad, and Calcutta fell on the Indian side close to the new border. Dhaka's status as a capital was restored. East Bengal eventually became Bangladesh in 1971, after a liberation war in which India played a major role. The July Revolution of 2024 later led to the ousting of Prime Minister Sheikh Hasina following mass protests, and Nobel laureate Muhammad Yunus took charge of an interim government to oversee institutional reforms.

  Satyendra Nath Bose was researching at the University of Dhaka in 1924-25 when he laid the foundation for Bose-Einstein statistics and the theory of the Bose-Einstein condensate, work that would reshape quantum mechanics. Sir Jagadish Chandra Bose became the first person from the Indian subcontinent to receive a US patent, in 1904, and the IEEE later named him one of the fathers of radio science. Meghnad Saha developed the thermal ionisation equations that became foundational in astrophysics and astrochemistry. The Gupta dynasty, believed to have originated in North Bengal, is associated with the invention of chess, the concept of zero, and the theory of the Earth orbiting the Sun.

  Bengali is the fifth most spoken language in the world, and the 1952 Bengali language movement in East Pakistan is now commemorated by UNESCO as International Mother Language Day. The language developed between the 7th and 10th centuries from Apabhramsha and Magadhi Prakrit, written in an alphabet descended from the ancient Brahmi script. Bengali has influenced Odia, Assamese, Chakma, Nepali, and Rohingya.

  Three Bengali economists have been Nobel laureates: Amartya Sen and Abhijit Banerjee for the Nobel Memorial Prize in Economics, and Muhammad Yunus for the Nobel Peace Prize. The region's literary heritage stretches from ancient folk traditions like the Chôrjapôdô through the medieval poetry of Chandidas and Alaol, to the Bengal Renaissance writers including Rabindranath Tagore, Kazi Nazrul Islam, and Begum Rokeya, to contemporary English-language novelists like Jhumpa Lahiri and Amitav Ghosh. Cox's Bazar in southeastern Bangladesh holds the longest natural sea beach in the world, unbroken for 120 km, a reminder that for all the weight of history this delta carries, geography still shapes what Bengal is.
