Vanijya-Adhikya: India's Perpetual Trade Surplus
Ocean of Churn Thesis
How Sanjeev Sanyal's research reveals India's maritime commercial dominance in the Indian Ocean for over two millennia.
The Ocean That Bears India's Name
Here's a question rarely asked: Why is the Indian Ocean called the Indian Ocean?
The Atlantic is named after Atlas. The Pacific means "peaceful." But the Indian Ocean? It's the only ocean named after a country. This naming wasn't accidental, it was recognition of reality. For over two thousand years, Indian merchants, Indian ships, and Indian goods dominated this vast maritime space.
Sanjeev Sanyal: The Modern Maritime Historian
Sanjeev Sanyal occupies a unique position in India's intellectual landscape. As Principal Economic Adviser to the Government of India and member of the Economic Advisory Council to the Prime Minister, he bridges rigorous scholarship with policy relevance. His book "The Ocean of Churn: How the Indian Ocean Shaped Human History" fundamentally reframes how we understand India's place in world trade.
Sanyal's central thesis is revolutionary yet evidence-based: the Indian Ocean wasn't merely a body of water India happened to border, it was a civilizational zone where India played the central role for millennia.
The "Churn" Concept: Samudra Manthan of Commerce
Sanyal deliberately evokes the mythological Samudra Manthan (churning of the ocean) to describe Indian Ocean dynamics. Just as gods and asuras churned the cosmic ocean to produce treasures, the continuous movement of people, goods, and ideas across this maritime space created civilizational wealth.
The churning was constant: African ivory flowing to India, Indian textiles reaching Arabia, Indian ideas transforming Southeast Asia, Chinese silk meeting Indian cotton. And at the center of this churn stood India, not passively receiving, but actively orchestrating the exchange.
Evidence of Maritime Dominance
Sanyal marshals multiple forms of evidence:
Archaeological Evidence:
- Indian artifacts discovered across Southeast Asia, East Africa, and Arabia
- Shipwrecks containing Indian cargo in the South China Sea
- Port infrastructure remains showing Indian merchant presence
- Temple complexes in Indonesia, Cambodia, and Vietnam built by Indianized kingdoms
Textual Evidence:
- Greek accounts describing Indian maritime activity (Periplus, Ptolemy)
- Chinese records of Indian traders at Canton and Quanzhou
- Arab geographers like Al-Masudi describing Indian Ocean trade networks
- Tamil Sangam literature documenting sea voyages to distant lands
Genetic Evidence:
- DNA studies showing Indian settlers across Southeast Asia
- Population movements that followed trade routes
- Cultural diffusion patterns matching commercial connections
The Maritime Empires of Bharat
Contrary to the colonial narrative that Indians were land-bound, India produced powerful maritime states:
The Satavahanas (230 BCE - 220 CE): Controlled the western coast, facilitated Roman trade through ports like Sopara and Kalyan. Their coins have been found across the Arabian Sea.
The Pallavas (275-897 CE): Dominated the eastern coast, sent merchants and Brahmins to Southeast Asia. Pallava script became the ancestor of Thai, Khmer, and Indonesian scripts.

The Cholas (300 BCE - 1279 CE): The greatest maritime power India produced. Rajendra Chola I led naval expeditions to Srivijaya (Indonesia) in 1025 CE. Chola merchant guilds like the "Ayyavole Five Hundred" operated from Arabia to China.
The Zamorins of Calicut (1124-1806 CE): Made Calicut the greatest spice port in the world. When Vasco da Gama arrived in 1498, he found a sophisticated trading system that had operated for centuries.
Cultural Power Through Commerce
Trade carried more than goods, it transported civilization. This is perhaps Sanyal's most important insight. Indian merchants didn't just sell textiles and spices; they carried ideas, scripts, religions, and legal systems.

The Hindu-Buddhist Spread:
- Angkor Wat in Cambodia, the world's largest religious monument, is dedicated to Vishnu
- Borobudur in Indonesia, the world's largest Buddhist temple, reflects Mahayana Buddhism from India
- The Ramayana and Mahabharata were adopted across Southeast Asia, adapted to local contexts
- Sanskrit became the prestige language of courts from Burma to Bali
Scripts and Knowledge:
- Thai, Khmer, Burmese, Javanese, and Balinese scripts derive from Indian Pallava and Grantha scripts
- Legal concepts from Dharmashastras influenced Southeast Asian law codes
- Indian astronomical and mathematical knowledge spread along trade routes
- Architectural styles transmitted through merchant-sponsored temples
This wasn't colonization, it was influence through commerce, the most durable form of soft power.
Global Perspectives on Indian Ocean Trade
Scholars from different traditions have grappled with understanding the Indian Ocean's unique commercial character, and India's central role within it.
K.N. Chaudhuri (1934-present), the Cambridge-trained economic historian, wrote the foundational text 'Trade and Civilisation in the Indian Ocean' (1985). He demonstrated that the Indian Ocean operated as a coherent economic system with India at its center. Unlike the Atlantic or Mediterranean, where military power dominated trade, the Indian Ocean was governed by commercial logic. Chaudhuri showed that European colonizers didn't create Indian Ocean trade, they disrupted an existing system that had functioned efficiently for centuries.
Janet Abu-Lughod (1928-2013), in 'Before European Hegemony' (1989), mapped eight interlocking trade circuits that constituted the pre-1350 world economy. Three of these circuits centered on the Indian Ocean, with Indian textiles and pepper as the universal commodities. Her work proved that a functioning global economy existed before European expansion, and that India was its manufacturing hub.
Philip Curtin (1922-2009), pioneer of cross-cultural trade studies, documented how Indian merchant communities, Chettiars, Gujaratis, Marwaris, established trading diasporas across the Indian Ocean rim. Unlike European trading companies that relied on state backing, Indian merchants operated through community networks that proved more durable and efficient.
| Scholar | Key Insight | Implication |
|---|---|---|
| Chaudhuri | Indian Ocean as coherent economic system | India was center, not periphery |
| Abu-Lughod | Pre-European global economy existed | Europe entered existing Indian-dominated networks |
| Curtin | Indian merchant diasporas | Community networks outperformed colonial companies |
These scholars, approaching the subject from different angles, converge on a revolutionary conclusion: the Indian Ocean was India's ocean, and remains so geographically, even if temporarily ceded politically.
Why Maritime Dominance Ended
Sanyal honestly addresses India's maritime decline:
External Factors:
- Portuguese arrival in 1498 with superior naval technology and willingness to use violence for trade
- Systematic European colonization of Indian Ocean ports
- Disruption of traditional trade networks through monopoly practices
Internal Factors:
- Gradual withdrawal from maritime activity after the 14th century
- Loss of naval capability as land-based empires prioritized cavalry over ships
- Shift of focus to continental concerns
- What Sanyal calls a "civilizational loss of confidence" in outward engagement
By the time the British arrived, India had largely ceded the seas. This wasn't inevitable, it was a strategic choice with lasting consequences.
The Return: India's Maritime Revival
Sanyal's work isn't merely historical, it's strategic prescription. He argues India must reclaim its maritime heritage:

Modern Initiatives Reviving Maritime Role:
- Indo-Pacific Strategy: India now thinks of itself as a maritime power again, engaging with the entire Indo-Pacific region
- Sagarmala Project: ₹8 lakh crore investment in port modernization and coastal shipping
- IMEC Corridor: India-Middle East-Europe Economic Corridor reconnects India to ancient trade routes
- Expanding Navy: Commissioning of INS Vikrant, India's first indigenously-built aircraft carrier
The QUAD: India's participation in the Quadrilateral Security Dialogue with the US, Japan, and Australia represents return to strategic engagement with the Indian Ocean, the same ocean Indians dominated for millennia.
The Living Lesson
Sanyal's message is clear: India's prosperity has always been connected to the sea. The periods of greatest wealth, the Mauryas with their Arabian Sea trade, the Cholas with their Indian Ocean empire, Gujarat under the Solanki dynasty, were periods of maritime engagement.
The colonial interlude saw India turned inward, its coastline becoming a boundary rather than a gateway. The twenty-first century offers an opportunity to reverse this, to reclaim what was always India's natural advantage.
As Sanyal writes: "Indians need to reclaim their maritime heritage. We were the ocean's masters for over two millennia. The Indian Ocean should again become the priority of Indian strategic and economic thinking."
This isn't nostalgia, it's recognition that geography doesn't change, and India's position at the heart of the Indian Ocean remains its greatest strategic asset.
This demonstrates the concept of 'soft power through commerce.' Trade relationships create cultural influence far more durable than military conquest. The temples of Angkor Wat and Borobudur stand today, centuries after the trade that inspired them ended.
Geographic advantage is the most durable form of competitive advantage, it cannot be replicated. India's 7,500 km coastline and central Indian Ocean position remain unchanged. What changed was India's utilization of this advantage.
The shreni system was an early form of corporation, limited liability, pooled capital, specialized management. It solved the principal-agent problem through reputation mechanisms and community enforcement.

Verses
नौभिर्वा वणिक्पथैर्वा येन केनाप्युपायेन द्रव्यमुपार्जयेत्
Naubhir vā vaṇikpathair vā yena kenāpyupāyena dravyam upārjayet
By ships, by merchant routes, or by whatever means available, one should earn wealth.
This sutra explicitly prioritizes maritime commerce, contradicting colonial narratives that Indians were land-bound. Ancient Indian economic thought recognized that seaborne trade offered returns impossible through agriculture alone, explaining why coastal kingdoms like the Cholas grew wealthiest.
Shukraniti, Chapter on Artha (Traditional rendering)
समुद्रं यः समाश्रित्य वर्तते स महीपतिः
Samudraṃ yaḥ samāśritya vartate sa mahīpatiḥ
He who relies upon the ocean becomes lord of the earth.
The Cholas understood this principle perfectly. Rajendra Chola's naval expeditions to Srivijaya (1025 CE) made the Cholas the most powerful Indian dynasty of their era, their maritime reach funded their terrestrial empire.
Political maxim, Attributed to Kautilyan tradition (Traditional rendering)

Case studies
Sagarmala: Rebuilding India's Maritime Infrastructure
In 2015, the Government of India launched Sagarmala, the most ambitious port development program in Indian history. With ₹8 lakh crore ($100 billion) in planned investment, the project aims to transform India's 7,500 km coastline from an underutilized boundary into an economic engine. The vision: develop 12 major ports, 200+ minor ports, 14 Coastal Economic Zones, and shift 80% of freight from congested roads to coastal shipping. By 2024, port capacity had increased from 1,500 MTPA (2015) to 2,600 MTPA. New ports at Vadhavan (Maharashtra) and Vizhinjam (Kerala) were designed as transshipment hubs to capture traffic currently handled by Colombo, Singapore, and Dubai. The explicit goal: make India a maritime hub again.
The sutra 'Samudraṃ yaḥ samāśritya vartate sa mahīpatiḥ', he who relies on the ocean becomes lord of the earth, provides the dharmic logic for Sagarmala. For centuries, India neglected this wisdom, allowing coastline to become boundary rather than gateway. Sagarmala represents civilizational course correction. The ports being developed, Paradip, Kandla, JNPT, are modern tirthas (crossing places), continuing the ancient function of connecting India to the world. The project explicitly invokes maritime heritage: the Vadhavan port is designed to serve the same trade corridors that made Sopara and Kalyan great in Satavahana times.
By 2024, India had risen to become the world's 4th largest port capacity. Coastal shipping volumes increased 60% from 2015 levels. The Vadhavan and Vizhinjam ports, when completed, will enable Indian ports to handle mega container ships that currently bypass India. Export logistics costs are targeted to fall from 14% of GDP to 9%, matching China's efficiency. The Maritime India Vision 2030 projects India among the world's top 5 maritime nations.
Geography is permanent; its utilization is choice. India's coastline remained constant through centuries of decline. What changed was strategic attention. Sagarmala proves that when policy aligns with geographical advantage, results follow. The ancient pattern, maritime engagement driving prosperity, is being restored through infrastructure investment.
Sagarmala's port-led development model is being studied by maritime nations from Indonesia to Nigeria. The insight that coastlines are economic assets requiring strategic investment, not just natural boundaries, is reshaping infrastructure planning across the Global South.
India's port capacity increased from 1,500 MTPA (2015) to 2,600 MTPA (2024), 73% growth in 9 years. The target is 10,000 MTPA by 2047.
INS Vikrant: India Reclaims the Seas
On September 2, 2022, Prime Minister Modi commissioned INS Vikrant, India's first indigenously designed and built aircraft carrier, at Cochin Shipyard. The 45,000-tonne vessel, named after the legendary carrier that served in the 1971 war, took 17 years to build and represented ₹20,000 crore in investment. But Vikrant was more than a ship. It was a statement: India could now design, build, and operate the most complex naval platform, joining an elite club of six nations with indigenous carrier capability. The commissioning ceremony deliberately invoked India's maritime heritage, with the carrier's crest featuring the Sanskrit motto 'जयेम सं युधि स्पृधः' (May we conquer those who fight against us).
INS Vikrant embodies the Chola spirit, the recognition that maritime power translates to national greatness. The lesson's theme that 'India's svadharma includes maritime engagement' is being enacted through naval expansion. PM Modi's commissioning speech explicitly invoked Rajendra Chola, the Maratha navy under Kanhoji Angre, and the Chera naval traditions. The carrier's naming after the original Vikrant (which means 'courageous') connects modern naval power to civilizational continuity. This isn't mere symbolism, it's strategic communication that India is reclaiming its ocean.
INS Vikrant gives India two-carrier capability (with INS Vikramaditya), enabling blue-water naval presence across the Indian Ocean. The indigenous construction created 2,000+ direct jobs and developed 500+ Indian vendors. More significantly, it demonstrated that India could master complex systems integration. A second indigenous carrier (IAC-2) is already planned. India's naval shipbuilding order book now exceeds ₹70,000 crore. The Chola naval capability that once dominated Southeast Asian waters is being rebuilt.
Maritime power requires indigenous capability, not just purchases. The Cholas built their own fleets; so must modern India. INS Vikrant proves that India can master complex maritime technology. The psychological impact, that India is no longer dependent on foreign powers for strategic systems, is as important as the military capability itself.
Indigenous aircraft carrier construction demonstrates that defense self-reliance creates industrial ecosystems benefiting the entire economy. South Korea's shipbuilding dominance followed a similar path: strategic patience in building domestic capability eventually produced global competitiveness.
INS Vikrant is 76% indigenous content, built with Indian steel, Indian weapons systems, and Indian design. Only the aircraft (MiG-29K) are foreign. India joins USA, UK, France, Russia, China, and Italy as nations capable of building aircraft carriers.

- Dwarkadhish Temple: Ancient temple at one of India's most significant ports, mentioned in maritime trade records. Dwarka was a major node in the Arabian Sea trade network for millennia.
Reflection
- How does understanding India as a 'maritime civilization' change common perceptions of Indian history? What has been lost by forgetting this dimension?
- What opportunities might India's coastline and Indian Ocean position offer in the 21st century? How might you personally contribute to or benefit from India's maritime revival?
