No gold-encrusted tomb, no treasury inscription proclaiming a king's wealth — and yet the Harappan economy left its mark across the ancient world. Carnelian beads from Gujarat have been found in royal graves at Ur in Iraq. Harappan seals turn up at Bahrain (ancient Dilmun) and in Mesopotamian excavations. Standardised weights — identical in ratio from Punjab to Gujarat — tell of a trading network that worked without writing we can read. The IVC was, above all, a merchant civilisation.
Agriculture: Crops and Domesticated Animals
The agricultural base of the Harappan economy rested primarily on the cultivation of wheat and barley in the Indus floodplain, where annual flooding deposited fertile silt. Wheat (two varieties: Triticum compactum and T. sphaerococum) and barley were the dominant food crops. Evidence for irrigation channels has been found, though the scale of irrigation remains uncertain compared to Mesopotamia's canal systems. Other crops included sesame, mustard, peas, and dates.
The most economically and historically significant crop, however, is cotton. Carbonised cotton fibres and seeds have been found at Mohenjo-daro, and cotton cultivation is now confirmed to have begun at Mehrgarh (Balochistan) as early as 5000–4000 BCE. The IVC is the first confirmed cotton-growing and cotton-weaving civilisation in the world — a fact that connects directly to India's later global reputation as a cotton textile exporter and is a reliable UPSC data point. The Greek word for cotton (sindon) may derive from Sindh, the IVC heartland.
Domesticated animals in the IVC included the humped bull (zebu/Bos indicus), buffalo, sheep, goats, pigs, elephants, and possibly camels. Dogs were also kept. Interestingly, the Harappan seals show abundant animal imagery — bulls, elephants, rhinoceroses, tigers — suggesting these animals had both economic and symbolic significance. No skeletal remains of the horse have been found in securely-dated Mature Harappan contexts — a fact of major importance discussed below.
The Absent Horse
The absence of the horse from the Mature Harappan archaeological record is one of the most significant and politically contested facts in Indian ancient history. No horse bones, no horse imagery on Harappan seals, and no horse-drawn vehicles have been found in securely-dated Mature Harappan (2600–1900 BCE) contexts. The one claimed exception — a fragment of bone from Surkotada (Gujarat) identified by Sandor Bökönyi as equine — has been disputed by other zooarchaeologists who classify it as belonging to a related equid (wild ass/Equus hemionus).
This matters intensely for the Aryan question. The Rigveda — the oldest text of the Aryan/Vedic people — is saturated with horse imagery: the horse sacrifice (ashvamedha), the chariot, the horse as a symbol of kingship. If the Aryans were the same as the Harappans (as some nationalist historiography suggests), we would expect horses in Harappan sites. Their absence is one of the strongest pieces of evidence that the Harappans and the Vedic Aryans were distinct cultural groups, and that the Aryans arrived or expanded into the subcontinent after the decline of the IVC. The geographical and temporal evidence supports this view.
Crafts and Industries
Harappan craft industries were diverse and sophisticated. Bead-making was one of the most important industries. Carnelian beads (made from red/orange chalcedony), in particular, were a major export item — etched carnelian beads with bleached patterns (made by applying sodium bicarbonate and firing) are distinctively Harappan and have been found as far as Mesopotamia and Central Asia. Lothal was a major centre of bead production; Chanhu-daro in Sindh specialised in bead-making.
Pottery was wheel-thrown and kiln-fired, with distinctive red-ware pottery with black painted designs. Pottery shapes were standardised across the IVC's territory. Bronze-casting produced both tools (axes, saws, chisels) and art objects — the famous Dancing Girl figurine from Mohenjo-daro (c. 2500 BCE) is a bronze statuette of a young woman in a confident, naturalistic pose, created by the lost-wax (cire perdue) method. Shell-working used shells from the Gujarat coast to make ladles, bangles, and inlay pieces. Textiles (cotton, wool), ivory carving, and steatite seal-carving were other major industries.
Weights, Measures, and Trade Standards
The Harappan system of weights and measures is one of the most remarkable aspects of the civilisation because of its uniformity across an enormous territory. Harappan weights were cuboid in shape, made of chert, jasper, or limestone, and followed a binary-decimal system: the series ran 1, 2, 4, 8, 16, 32, 64 (binary), then scaled to 160, 320, 640, 1,600, 3,200, 6,400, 8,000, 12,800. The smallest unit was approximately 0.86 grams.
This same weight system — with weights of identical ratio — has been found at sites across the entire IVC territory from Harappa in Punjab to Lothal in Gujarat, over 1,500 kilometres apart. This consistency implies either a strong centralised authority enforcing trading standards, or a deeply embedded cultural norm that merchants internalised. A linear measure is also evidenced: a shell-made ruler found at Mohenjo-daro and another found at Lothal both show divisions of approximately 1.32 mm (the "Indus inch"), with remarkable precision.
With reference to the trade of the ancient Harappan Civilization, consider the following statements:
- The people of Harappan civilization did not have knowledge of the use of wheel.
- The people of Harappan civilization traded with Mesopotamia.
- Trade between Harappan civilization and Mesopotamia was facilitated through an intermediate region called Dilmun.
Which of the statements given above is/are correct?
Trade with Mesopotamia: Meluhha
Meluhha is the Sumerian-Akkadian term for the IVC, appearing in cuneiform texts from at least c. 2350 BCE (Akkadian period of Sargon of Akkad) through the Ur III period (c. 2100–2000 BCE). Mesopotamian texts record that goods came from Meluhha by ship, including carnelian (prized for jewellery), etched carnelian beads, lapis lazuli, ivory, timber (particularly teak), and what may be cotton textiles (the Sumerian word for cotton may be a loanword from Harappan).
Physical evidence confirms the textual record: Harappan seals have been found at Ur (excavated by Leonard Woolley in the 1920s), at Kish, and at other Mesopotamian sites. Conversely, some Mesopotamian cylinder seals and objects have been found in IVC-affiliated sites. The intermediate point in this trade network was Dilmun (modern Bahrain) and possibly Magan (Oman), which Sumerian texts describe as way-stations through which Meluhha goods were transshipped. This three-point trade network — IVC → Dilmun/Magan → Mesopotamia — is directly tested in UPSC.
The sea route ran from Gujarat ports (especially Lothal) across the Gulf of Kutch, up the Arabian Sea coast past Magan/Oman and through Dilmun/Bahrain to the Tigris-Euphrates delta. The route was roughly 2,500 kilometres each way. The existence of this route and its goods are a reminder that "ancient India" was not isolated — it was embedded in a Bronze Age international economy.
Lothal's Dockyard and Maritime Trade
Lothal (literally "mound of the dead" in Gujarati — same meaning as Mohenjo-daro in Sindhi) is located in Bhavnagar district, Gujarat, and was excavated by S.R. Rao between 1955 and 1962. It was a major IVC port city on the Sabarmati river estuary, and its most spectacular feature is the dockyard — a large rectangular brick-lined basin (roughly 218 m × 36 m) with inlets that could be sealed by wooden gates to control water levels. This is the earliest known dockyard in the world.
Lothal was also a major centre for bead-making (carnelian, steatite, shell, gold), with workshops and evidence of large-scale production. A warehouse structure near the dockyard held goods waiting for export. The site also shows evidence of rice cultivation — one of the earliest confirmed rice-growing sites in Gujarat. The dedicated article on IVC sites covers Lothal's archaeology in full detail.
Internal Trade and the Seals
Within the IVC's territory, trade was facilitated by a sophisticated system of standardised seals. Over 3,500 Harappan seals have been found, mostly square or rectangular steatite (soapstone) stamps with an animal image (most commonly the "unicorn" — a bull shown in profile with one horn; also elephant, rhinoceros, tiger, and "proto-Shiva" figure) and an inscription in the undeciphered Indus script. The backs of seals have a boss (knob) for holding.
The seals are believed to have functioned as merchant identity marks or commodity labels. A merchant would press the seal into wet clay applied to a bale of goods, creating a sealed tag that identified the merchant and/or the goods. Sealing clay (sealings) with impressions of Harappan seals have been found in warehouses at Mohenjo-daro and Lothal, confirming this commodity-labelling function. The uniformity of the script across the IVC's territory (even though we cannot read it) implies a shared writing system used by merchants across regional boundaries.
With reference to the cultural heritage of India, consider the following crafts:
- Pottery
- Metalwork in bronze
- Bead-making from carnelian
Which of the above crafts were practised by the people of the Indus Valley Civilisation?
Exam Takeaway Five UPSC-critical facts from this article: (1) IVC = first cotton-growing civilisation in the world; (2) Horse = NOT found in Mature Harappan contexts — crucial for the Aryan/IVC debate; (3) Meluhha = IVC in Mesopotamian texts; Dilmun (Bahrain) = intermediate trade point; (4) Harappan weights = binary-decimal system, smallest unit ~0.86 grams, standardised across 1,500+ km; (5) Lothal dockyard = earliest known dockyard in the world. The wheel WAS known to Harappans (carts, potter's wheels) — a common wrong-answer option.
