Trade routes, ports and Indo-Roman commerce

Detail

The two great highways: Uttarapatha and Dakshinapatha

• From the 6th century BCE, land routes and river routes criss-crossed the subcontinent. They tied villages, towns and ports into one network.
• Uttarapatha — the "northern road". It ran from the northwest (the passes into Afghanistan and Central Asia), down into the Ganga plains, and on to eastern India.
• Dakshinapatha — the "southern road". It began at Kaushambi, near modern Prayagraj, crossed the Vindhya hills, and went into the Deccan and the south.

• Kaushambi was excavated by ASI in 1949–50, and the report Excavations at Kausambi (1949-50) is published on the Indian Culture portal — the site is one of the earliest dug-up river-plain towns on this route [4].

• Lateral (side) roads branched off both highways and ran to the coastal ports. So a bale of cloth could move by road, then by river, then by ship, without breaking the chain.

• Rulers offered protection for a price. Kings taxed and guarded the traffic. Trade paid for the state, and the state made trade safe. That is the deal at the heart of early Indian commerce.

Where the routes went beyond India

• Overland into Central Asia — the Kushanas controlled sections of the Silk Route. This is why a Kushana king's coins turn up far from his capital.
• Across the Arabian Sea — to East Africa, North Africa and West Asia (the Roman world reached India through Egypt and the Red Sea).
• Through the Bay of Bengal — to Southeast Asia and China.
• The monsoon made the sea leg possible. The southwest monsoon was known to the Greeks as Hippalus, after a sailor credited with first sailing straight from the Gulf of Aden to the Indian peninsula [3].
• Before this, ships hugged the coast — slow, and every local middleman took a cut.
• After it, ships sailed direct from Cana to the Malabar coast where black pepper grew.
• Result: the price of spices inside the Roman Empire fell by more than half [3]. Fewer middlemen, cheaper pepper, bigger volume.

Who the traders were

• Three levels of risk and reward:
• Peddlers on foot — smallest, carried goods on their own back.
• Caravans — bullock carts and pack animals moving in groups for safety.

• Seafarers — high risk, high profit. A lost ship meant total loss; a safe one meant a fortune.

• Words for a successful merchant (exam favourites):

• masattuvan — Tamil.

• setthi and satthavaha — Prakrit.

• Goods carried: salt, grain, cloth, metal ores and finished metal products, stone, timber, medicinal plants.

• What Rome specially wanted: pepper, textiles and medicinal plants.

The Periplus of the Erythraean Sea

• A handbook written by an anonymous Greek sailor, c. 1st century CE.
• The name explained: periplus means "sailing around" (a coast-by-coast guide); Erythraean means the Red Sea.
• It is a working trader's manual — it lists ports one after another down the Indian coast, including Muziris (Cranganore), Colchi (Korkai), Poduca and Sopatma [3].
• On the Malabar coast it records:
• Imports into India — a great quantity of coin, topaz, antimony, coral, crude glass, copper, tin, lead.

• Exports out of India — pepper, malabathrum (possibly cinnamon), fine pearls, ivory, silk cloth, transparent stones, diamonds and sapphires, tortoise shell.

• Read the list carefully — it is an exam point in itself. India sent out plants, gems and cloth; Rome sent back metal and, above all, money. India ran a trade surplus. That is why Roman coins pile up in India and Indian coins do not pile up in Italy.

Archaeology that backs the texts

• Kodumanal (Tamil Nadu) — a bead-making industry. The beads it made most likely fed the ports for export. Craft village inland, ship at the coast: the two ends of one system.
• Roman coin hoards across south India — Rome never ruled any part of south India, yet its coins are found there in bulk. Lesson for Mains: trade crossed political boundaries; you do not need an empire to have an economy.
• Satavahana coins depict two-masted ships. A king putting a ship on his coin is advertising sea power and sea profit.

• Satavahana–Roman trade: out went spices, textiles, sandalwood, ivory and gold-plated pearls; in came glass and perfumed ointments.

• Arikamedu (near modern Puducherry) — excavation revealed a Roman trading settlement. Finds: Roman pottery, beads, intaglios (carved gem seals), lamps, glass and coins. The mix shows continuous occupation, and local workers even made imitations of Roman items. Textiles were made to Roman specification and exported from such settlements [3].

• The classic ASI report on it is titled An Indo-Roman Trading Station on the East Coast of India, in Ancient India Volume 2 [2].

• Roman Arretine ware — the red polished pottery found at such sites — was made at Arretium (modern Arezzo) in factory-style potteries working c. 30 BCE – 30 CE [3]. That narrow date band helps archaeologists date the Indian layers where it turns up.

• Gottiprolu (Nellore district, Andhra Pradesh) — ASI Excavation Branch VI, Bengaluru, identified it as an early historic trade centre [5].

• It sits on the right bank of a distributary of the Swarnamukhi river, about 17 km east of Naidupet, and 80 km from Tirupati and Nellore — a river-mouth spot, ideal for moving goods to the sea.
• Main find: a massive baked-brick enclosure wall, exposed for over 75 m, average width 3.40 m, surviving height nearly 2 m, curving in plan. Drone images and topographic survey suggest a moat around the settlement.
• Also found: elliptical, circular and rectangular brick structures, pottery of the early centuries CE, and a 2 m tall four-armed Vishnu sculpture standing on a pedestal with chakra and conch, dated on style to the Pallava period, c. 8th century CE [5].
• Why it matters: a walled and possibly moated trade town proves merchants' wealth needed defence, and that trading settlements were planned, not accidental.

The ports

• Muziris — on the Malabar coast; the pepper port of the Periplus, also called Cranganore [3].
• Kaveripattinam — also known as Puhar or Poompuhar; the Chola port at the mouth of the Kaveri.
• Arikamedu — the Coromandel (east coast) site with Roman material.
• Masulipatnam — on the Andhra coast, facing the Bay of Bengal and Southeast Asia.
• The Tamil epic Silappadikaram names routes from Kanchipuram to Poompuhar and from Kanchipuram to Kanyakumari.
• This is the key proof that overland and maritime systems interlocked. The road ended where the ship began.

Prelims Hooks

• Dakshinapatha started at Kaushambi (near Prayagraj) and crossed the Vindhyas; Uttarapatha linked the northwest to eastern India.
• The Periplus of the Erythraean Sea was written by an anonymous Greek sailor, c. 1st century CE; periplus = "sailing around", Erythraean = Red Sea.
• Periplus Malabar exports: pepper, malabathrum (possibly cinnamon), pearls, ivory, silk cloth, diamonds, sapphires, tortoise shell. Imports: coin, topaz, antimony, coral, crude glass, copper, tin, lead.
• Masattuvan = Tamil for a rich merchant; setthi and satthavaha = the Prakrit terms.
• Satavahana coins show two-masted ships.
• Kodumanal (Tamil Nadu) = bead-making centre feeding the ports.
• Arikamedu (near Puducherry) yielded Roman pottery, intaglios, lamps, glass, beads and coins; the ASI report is An Indo-Roman Trading Station on the East Coast of India (Ancient India Vol. 2) [2].
• Roman Arretine ware was produced at Arretium (Arezzo) between about 30 BCE and 30 CE [3].
• The southwest monsoon was called Hippalus by the Greeks; direct sailing cut Roman spice prices by more than half [3].
• Gottiprolu (Nellore dist., AP): early historic trade centre with a brick enclosure wall over 75 m long, 3.40 m wide, and a 2 m four-armed Vishnu image of the Pallava period (c. 8th century CE) [5].
• The Silappadikaram records routes from Kanchipuram to Poompuhar and to Kanyakumari.

Mains Points

• Trade does not need conquest. Rome never ruled south India, yet Roman coin hoards are spread across the peninsula and Arikamedu has Roman pottery and glass [3]. Economic links ran far beyond political frontiers — a useful line whenever a question asks about India's early "global" connections.
• Technology changed the structure of trade. Knowing the monsoon (Hippalus) turned coast-hugging into open-sea sailing. That cut out middlemen, halved spice prices in Rome [3], raised volume, and shifted profit to whoever held the Malabar ports. Link this to why Muziris became so important.
• State and merchant were partners. Rulers protected routes for a price; merchants funded the state through tolls and taxes. Walled trade towns like Gottiprolu [5] and the Kushana hold on the Silk Route show the same bargain in two different regions.
• Inland craft and coastal port formed one chain. Beads from Kodumanal, cloth made to Roman specification at settlements like Arikamedu [3], and the Silappadikaram road-to-port routes show production, transport and export were integrated — not three separate worlds. Use this against any claim that early Indian villages were closed, self-sufficient units.
