The Origin of the Name Bengal: From Banga to Vanga to the Modern Era

The name "Bengal" — known in the native tongue as "Bangla" (বাংলা) — is one of the oldest continuously used geographical names in the Indian subcontinent. Its roots stretch back not merely centuries but millennia. The name reaches into the deep prehistory of South Asia, long before the advent of Vedic civilisation.

The modern name "Bengal" derives from the ancient term "Vanga" (Sanskrit: वङ्ग, Vaṅga), which was also rendered as "Banga" (বঙ্গ). The transition from Vanga to Banga to Bangalah to Bengal represents one of the most enduring linguistic evolutions in South Asian history. This document traces that evolution from its deepest prehistoric roots through Puranic and Vedic literary traditions, to the inscriptions of South Indian temples.

1. The Prehistoric Pre-Vedic Roots: Bonga and the Austro-Munda Connection

The deepest and most ancient layer of the name "Banga" predates both the Aryan (Vedic) and Dravidian migrations into the Bengal region. According to linguistic and ethnographic research, the word "Bonga" (বঙ্গ/Bonga) is an Austro-Munda term meaning "Sun-god" (Scroll.in).

The Austric peoples — a broad linguistic group that includes the Austroasiatic (Munda/Khasi) and Austronesian language families — were among the earliest inhabitants of the Indian subcontinent. The Munda languages are spoken by tribal communities in Bihar, Jharkhand, Odisha, Chhattisgarh, and Bengal. These languages are considered among the oldest language strata in South Asia (Scroll.in).

According to this theory:

"Bonga" was the name of the Sun-god in the pre-Vedic Munda religious tradition.
The Austric-speaking peoples who inhabited the Ganges-Brahmaputra delta region worshipped the Sun under this name.
The territory where this Sun-worship was practised came to be known as "Bonga-land" or "Bonga-desh."
Later populations — first Dravidian, then Indo-Aryan — moved into the region and adopted this pre-existing name.
The Dravidian-speaking migrants adapted "Bonga" to "Vanga" (वङ्ग), as the Dravidian language family does not typically use initial voiced stops in the same way as Munda languages (Scroll.in).

The Banglapedia (National Encyclopedia of Bangladesh) states: "The exact origin of the word Bangla is unknown, though it is believed to be derived from the Dravidian-speaking tribe Bang/Banga that settled in the area around the year 1000 BCE" (Banglapedia).

The Wikipedia article on "Names of Bengal" lists "Bonga" as the earliest known form, described as "an Austric word for Sun god" (Wikipedia).

2. The Proto-Dravidian Theory: The Bang Tribe

An alternative or complementary theory suggests that the name derives from a Proto-Dravidian tribal group called "Bang" or "Banga" who settled in the region around 1000 BCE (Banglapedia).

According to this theory:

Before the arrival of Indo-Aryan (Vedic) peoples, the Bengal region was inhabited by Dravidian-speaking tribes.
One such tribe was called "Bang" or "Banga."
This tribe settled in the eastern delta region and gave its name to the territory.
When the Aryans arrived, they encountered this pre-existing Dravidian-speaking population and adopted the name, rendering it as "Vanga" in Sanskrit (Banglapedia).

The evolution according to this theory follows this sequence:

BANG (Proto-Dravidian tribal name, c. 1000 BCE)
BANGA (adapted into early Indo-Aryan, c. 800-600 BCE)
VANGA (Sanskrit adaptation, c. 600-500 BCE)
BANGA/VANGA (used interchangeably in epic and Puranic literature)
VANGALA/BENGALA (medieval South Indian and Arab forms)
BENGAL/BANGLA (modern English and Bengali forms) (Banglapedia)

These two theories — the Austro-Munda and the Proto-Dravidian — are not mutually exclusive. The Munda and Dravidian peoples lived in close proximity in eastern India, and inter-marriage and cultural exchange between them was common. The name "Banga" may represent a fusion of both linguistic traditions (Banglapedia).

3. The Boat-Ship Theory (Vangam) and the Marshy Land Theory (Vanka)

Two closely related theories deserve special attention. They are grounded in the physical and cultural reality of the Bengal region: its rivers, its waterways, and its ancient maritime traditions. Together, these theories provide the most compelling and evidence-based explanation for the origin of the name Vanga/Banga (Tamil and Vedas).

3.1 The Boat-Ship Theory: Vangam as "Ship"

The Boat-Ship Theory proposes that the word "Vanga" (and its Tamil form "Vangam" — வங்கம்) originally meant "ship" or "sea-faring vessel" (Tamil and Vedas). This theory is supported by extensive evidence from Tamil Sangam literature, one of the oldest bodies of secular literature in the Indian subcontinent, dating from approximately 300 BCE to 300 CE (The MUA).

Key evidence:

ANDAL'S TIRUPPAVAI (c. 8th century CE): The Tamil Vaishnavite poetess Andal used the term "Vanga Kadal" (வங்கக் கடல்) in verse 30 of her Tiruppavai. This means "the sea where ships (Vanga = ship) sail" (Tamil and Vedas)(Wikipedia).
SANGAM LITERATURE — NATRINAI (c. 200 BCE - 200 CE): A Sangam poet used the phrase "Gangai Vangam" (கங்கை வங்கம்), meaning "ships sailing through the River Ganges" (Natrinai, verse 189). This directly links the word "Vangam" to riverine navigation on the Ganges (Tamil and Vedas)(The MUA).
SANGAM LITERATURE — PURA NAANURU (c. 200 BCE - 200 CE): The poet Kovur Kizar mentioned the ports of Tamil Nadu and the facilities for sea-faring vessels, using the term "Vangam" (Pura Naanuru, verse 400). This confirms that "Vangam" was a standard Tamil word for ocean-going vessels (Tamil and Vedas).
TAMIL NAVAL TERMINOLOGY: Early Tamil texts distinguish several types of watercraft. "Kalam" is a local timber vessel. "Naavai" is an ocean-going vessel. "Vangam" is a vessel fitted with a mast and flying a flag. The fact that "Vangam" specifically denotes a mast-equipped, flag-bearing vessel suggests a sophisticated sailing ship (The MUA).
THE BAY OF BENGAL: The body of water south of Bengal was itself called "Vanga Kadal" (வங்கக் கடல்) in Tamil, meaning "the Sea of Vangam/Ships." This is the earliest recorded name for the Bay of Bengal (Tamil and Vedas)(Wikipedia).
THE CHANDRAKETUGARH TERRACOTTA BOATS: Archaeological discoveries at Chandraketugarh (c. 300 BCE-100 CE) in West Bengal include numerous terracotta plaques depicting elaborately decorated boats and ships (Wikipedia).
THE MARITIME IDENTITY OF VANGA: The Vanga kingdom was renowned as a thalassocracy — a maritime power. The Mahabharata describes Vanga as "a hub of sailors" with a powerful navy (Wikipedia). In the 5th century BCE, the Vanga prince Vijaya sailed across the Bay of Bengal to found the first kingdom in Sri Lanka (Wikipedia).

3.2 The Marshy Land Theory: Vanka as "Crooked Waterway"

Closely related to the Boat Theory is the Marshy Land Theory. This theory proposes that "Vanga" derives from the Sanskrit/Prakrit word "Vanka" (वङ्क), meaning "crooked" or "winding" — specifically referring to the winding waterways, channels, and rivers of the Bengal delta.

Key evidence:

SANSKRIT "VANKA" (वङ्क): In Sanskrit, "vanka" means "crooked, curved, winding." The Romani language preserves this meaning: the Romani word "bango" (from Sanskrit vanku) means "crooked" or "distorted" (Banglapedia).
KANNADA "VANKA" (ವಂಕ): The Kannada word "vanka" carries multiple meanings: (1) the quality of being crooked; (2) a steady flow of water, as of a river or stream; (3) a way, path, or road; (4) an ox with curved horns (Banglapedia).
BENGALI "BANKA" (বাঁকা): The modern Bengali word "banka" means "bent, curved, winding, sinuous." It is a direct descendant of the Sanskrit "vanka" (Banglapedia).
THE TIMES OF INDIA (2011): The historian noted: "Banga in its etymological sense means Vanga or Vanka — marshy land. It denotes the entire stretch of lower Bengal when the sea receded and the landmass became fit for human habitation" (Scroll.in).
THE GANGES DELTA: The Ganges-Brahmaputra delta is the world's largest river delta. It is "a labyrinth of channels, swamps, lakes, and flood plain sediments (chars)." The word "Vanka" — meaning winding waterways — is a perfect description of this landscape (Wikipedia).

3.3 The Synthesis of Both Theories

The Boat-Ship Theory and the Marshy Land Theory are not mutually exclusive. They complement each other:

The "Vanka" (crooked waterways) of the Bengal delta created the conditions for a maritime civilisation.
The ships ("Vangam") that navigated these waterways and sailed the open seas gave the region its name.
The land was both "the land of winding waterways" (Vanka-desa) and "the land of ships" (Vanga-desa).
Both meanings converge on the same fundamental truth: Bengal was named for its relationship with water.

4. The Puranic Origin: King Vali and His Six Sons

The Hindu Puranic tradition provides a mythological genealogy for the Vanga kingdom. According to the Bhagavata Purana (Srimad Bhagavatam) and the Mahabharata, the story is as follows (Tamil and Vedas):

KING VALI (बलि/बाली), a righteous king of the lunar dynasty (Chandravamsha), was a descendant of the great Yayati through the line of Anu. King Vali, despite his piety and power, had no sons. He sought the help of the aged sage DIRGHATAMAS (दीर्घतमस्), who lived in Magadha near the city of Girivraja (modern Rajgir).

Through the ancient practice of NIYOGA (procreation by a designated person), Dirghatamas begat five sons through Queen SUDESHNA (सुदेशना), the wife of King Vali:

ANGA (अङ्ग) — who founded the kingdom of Anga (modern eastern Bihar)
VANGA (वङ्ग) — who founded the kingdom of Vanga (Bengal)
KALINGA (कलिङ्ग) — who founded the kingdom of Kalinga (modern Odisha)
SUHMA (सुह्म) — who founded the Suhma kingdom (southern West Bengal)
PUNDRA (पुण्ड्र) — who founded the Pundra kingdom (northern Bengal/Bangladesh)

Some texts add a sixth son:

ODRA (ओद्र) — who founded the Odra kingdom (modern western Odisha)

The Bhagavata Purana (Skanda XII, Chapter 31) states:

"By the semen of Dirghatamas in the wife of Bali, the emperor of the world, six sons took birth — namely Anga, Vanga, Kalinga, Suhma, Pundra and Odra." (Tamil and Vedas)

This Puranic narrative establishes Vanga as one of the oldest named political entities in Indian history. It connects Bengal to the lunar dynasty and the broader mythological framework of Hinduism (Tamil and Vedas).

5. The Vedic and Epic References

5.1 The Aitareya Aranyaka (c. 700-500 BCE)

The earliest textual reference to "Vanga" is found in the AITAREYA ARANYAKA (ऐतरेय आरण्यक), one of the oldest Aranyaka texts of the Rigveda (Banglapedia). This text dates to approximately 700-500 BCE.

In the Aitareya Aranyaka (Book II), the Vangas are mentioned alongside the Magadhas:

वयांसि वङ्गाबगधानां चेरापाद
(Vayamsi Vanga-Bagadhana-mera-pada)
Translation: "Like birds, the Vangas and Magadhas [and] the Chera-Padas [move about chirping]." (Banglapedia)

This passage is significant because it is the first known written reference to the Vanga people. It groups the Vangas with the Magadhas, suggesting that in the early Vedic period, these peoples were neighbours.

The Banglapedia confirms: "The name Vanga, indicating a people, occurred for the first time in the Aitareya Aranyaka, where they are mentioned along with the Magadhas" (Banglapedia).

5.2 The Mahabharata (c. 400 BCE - 400 CE)

The Vanga kingdom receives extensive attention in the Mahabharata. Vanga is mentioned in numerous passages across multiple books of the epic (Wikipedia):

SABHA PARVA (Book II): Lists the Vangas among the Kshatriyas who supported Jarasandha of Magadha (II.13.19). Describes Bhimasena's conquest of the Vanga king during his eastern campaign (II.27.21). Lists the Vangas among the kingdoms that brought tributes to Yudhishthira's Rajasuya sacrifice (II.31.11).
VANA PARVA (Book III): Arjuna's pilgrimage includes a visit to the sacred waters of Vanga and Kalinga (III.82).
KARNA PARVA (Book VIII): Mentions warriors from Vanga fighting against Dhrishtadyumna in the Kurukshetra War (VIII.17.2).

5.3 The Manu Smriti

The Manusmriti (Laws of Manu) includes Bengal within the geographical boundary of Aryavarta (the land of the Aryans). It notably prohibits all contact of Hindus with Bengal "for fear of contamination." This suggests that Bengal was culturally distinct — possibly still influenced by pre-Aryan religious practices — even as late as the period of the Smriti texts (Banglapedia).

6. The Evolution from Vanga to Banga to Bengal

The linguistic evolution of the name passed through several stages (Banglapedia):

BONGA (Pre-Vedic, pre-1000 BCE): Austro-Munda term for Sun-god. Earliest layer of the name's history.
BANG (Proto-Dravidian, c. 1000 BCE): Name of a Dravidian-speaking tribe. Used as a tribal/ethnic designation.
VANGA/BANGA (Indo-Aryan adaptation, c. 800-500 BCE): First appears in Aitareya Aranyaka. Both forms coexist.
VANGALA (Medieval South Indian, c. 800-1200 CE): Tamil and other Dravidian language adaptation. Found in Chola and Pandya inscriptions.
BANGALAH/BENGALAH (Medieval, c. 1200-1700 CE): Arab and Muslim period designation. Abu'l-Fazl explained: "The original name of Bengal was Bung, and the suffix 'al' came to be added to it."
BENGAL/BANGLA (Modern, 1700 CE onwards): British colonial anglicization. "Bengal" in English. "Bangla" (বাংলা) in Bengali (Banglapedia).

The Banglapedia entry on Bangalah states: "Abul Fazl, the Mughal historian explained the origin of the name thus: The original name of Bangalah was Bang. Its former rulers raised mounds measuring ten yards in height and twenty in breadth throughout the province, which were called al. From the suffix, this name Bangalah took its rise and currency" (Banglapedia).

7. The Vanga Kingdom in Hindu Texts

The Vanga kingdom described in Hindu texts was a powerful thalassocracy (maritime empire) (Wikipedia):

NAVY AND MARITIME POWER:

The Mahabharata describes Vanga as a major naval power.
Vanga's navy controlled many of the islands of the Ganges delta.
Ancient Indian records refer to Vanga as "a hub of sailors" (Wikipedia).

OVERSEAS COLONIES:

In the 5th century BCE, the Vanga king SIHABAHU's son, Prince VIJAYA, sailed across the Bay of Bengal and established a kingdom in what is now Sri Lanka (Wikipedia).
This colonial venture is recorded in both Indian and Sri Lankan chronicles (the Mahavamsa and Dipavamsa).

8. South Indian Inscriptions and the Name Vangaladesa

The name "Vangaladesa" (the land of Vanga/Bengal) appears in numerous South Indian inscriptions from the Chola, Pandya, and other Dravidian dynasties (Banglapedia).

KEY EPIGRAPHIC REFERENCES:

The Brihadisvara Temple at Thanjavur (built 1010 CE by Rajaraja Chola I) contains inscriptions that reference "Vangalam" as the Bengal region (Banglapedia).
The Comilla inscription of 409 CE was issued by Maheshwar Nathachandra, king of Samatata. Landlords with the suffix "Vangala" donated land for the construction of a temple of Lord Manibhadra. This is one of the earliest epigraphic uses of the term "Vangala" (Banglapedia).
The Nesari plates of 805 CE (Rashtrakuta dynasty) mention Pala King Dharmapala as "Vangala-bhupati" (King of Vangala/Bengal) (Wikipedia).
The Chola military records of Rajendra Chola I (r. 1014-1044 CE) reference the conquest of territories in Bengal under the name "Vangaladesa" (Banglapedia).

8.1 The Nesari Plates and Dharmapala of Vangala

The Nesari plates, dated to 805 CE, are a copper-plate grant issued by the Rashtrakuta dynasty. They contain a crucial reference:

"Dharmapala — Vangala-bhupati" (Dharmapala — King of Vangala) (Wikipedia)

This identifies Pala King Dharmapala (r. c. 770-810 CE), the second ruler of the Pala dynasty, as the "King of Vangala." The Banglapedia entry on Vangala confirms: "The earliest reference to Vangala, phonetically similar to Vanga, is found in the Nesari plates (dated 805 AD) of the Rastrakuta king Govinda III, where the contemporary Pala king Dharmapala is mentioned as the king of Vangala" (Banglapedia).

8.2 The Tirumala-Tirupati Inscriptions and Bengal

The Tirumala-Tirupati Devasthanams houses approximately 1,150 inscriptions dating from the 8th to 18th centuries CE (Tamil and Vedas). These inscriptions were issued by dynasties including the Pallavas, Cholas, Pandyas, and Vijayanagara kings.

The Tirumala inscriptions document the activities of the Chola dynasty, which is connected to Bengal through military campaigns. Rajendra Chola I launched a grand northern expedition (approx. 1023-1025 CE) that reached the banks of the Ganges. His conquests included territories in Bengal, and the Chola records reference "Vangaladesa" as a conquered territory (Tamil and Vedas).

9. Medieval and Modern Evolution of the Name

The transition from "Vanga/Banga" to the modern "Bengal/Bangla" occurred through several intermediate stages (Banglapedia):

EARLY MUSLIM PERIOD (1204-1400 CE):

After the Muslim conquest of Bengal in 1204 CE, the region was referred to as "Bang" in Arabic and Persian records.
The term "Bangalah" came into common use in the mid-14th century.

MUGHAL PERIOD (1576-1757 CE):

The Mughals included Bengal as a province called "Subah-i-Bangalah."
Abu'l-Fazl, the court historian of Akbar, explained the origin of the name.

BRITISH COLONIAL PERIOD (1757-1947 CE):

The British anglicized "Bangal" to "Bengal."
The Bengal Presidency became one of the major administrative divisions of British India (Banglapedia).

MODERN PERIOD (1947-PRESENT):

The Partition of Bengal in 1947 created East Bengal and West Bengal.
In 1971, East Pakistan became the independent nation of BANGLADESH — literally "Land of Bengal."
The native Bengali name "Bangla" (বাংলা) is used by both Bangladesh and West Bengal (Banglapedia).

10. Conclusion — Why the Boat Theory Is the Strongest

The name "Bengal" — in its various forms of Bonga, Bang, Banga, Vanga, Vangala, Bangalah, and Bengal — represents one of the most ancient and enduring geographical names in human history. Its roots extend deep into the prehistory of South Asia, predating the Vedic civilisation by potentially thousands of years.

The Boat-Ship Theory emerges as the most convincing and well-supported for the following reasons (Tamil and Vedas):

TAMIL LINGUISTIC EVIDENCE IS CONCRETE: The Tamil Sangam literature provides the clearest and most direct evidence. The word "Vangam" consistently and unambiguously means "ship" in Sangam texts. This is documented in at least eight separate instances across multiple Sangam works (Tamil and Vedas)(The MUA).
THE BAY OF BENGAL WAS CALLED "VANGA KADAL": The fact that the body of water south of Bengal was itself named "Vanga Kadal" (Sea of Vangam/Ships) provides the strongest possible link between the word "Vanga" and maritime activity. A region named after its ships would naturally give its name to the sea those ships sailed (Tamil and Vedas)(Wikipedia).
GEOGRAPHY MATCHES THE MEANING: The Bengal delta is the world's largest river delta. The Sanskrit "Vanka" (crooked/winding) perfectly describes this landscape (Banglapedia)(Wikipedia).
ARCHAEOLOGICAL EVIDENCE SUPPORTS MARITIME IDENTITY: Chandraketugarh terracotta plaques (c. 300 BCE) depict elaborately decorated boats and ships, confirming a sophisticated maritime culture in the Bengal region (Wikipedia).
THE VANGA KINGDOM'S MARITIME POWER IS HISTORICAL FACT: The Mahabharata describes Vanga as a thalassocracy with a powerful navy. Prince Vijaya's voyage to Sri Lanka in the 5th century BCE is confirmed by Indian and Sri Lankan chronicles. A kingdom defined by its ships would naturally be named after them (Wikipedia)(Wikipedia).
PARALLEL EVIDENCE FROM KALINGA: The Boita tradition of Odisha (ancient Kalinga), Vanga's sister kingdom, confirms that maritime culture was central to the identity of eastern Indian kingdoms. The Sadhabas who sailed in Boitas across the Bay of Bengal were part of the same maritime world as the Vangam-sailing Vangas (Wikipedia).

The name "Bengal" is thus best understood as meaning "Land of Ships" or "Land of Winding Waterways." The Ganges-Brahmaputra delta, with its thousand rivers and its ancient maritime tradition, gave the world a name that has endured for over three thousand years: Vanga — the land of ships.
