1. Harappan Economy: Specialized Craft Production (basic)
To understand the Indus Valley Civilisation, we must look beyond its massive brick walls and see the hands of its artisans. Craft production was not just a hobby but a
highly specialized pillar of the Harappan economy. Unlike simple village economies where everyone makes their own tools, Harappan society featured professional craftsmen who mastered specific materials and techniques to produce goods for both local use and long-distance trade
History, Class XI (Tamilnadu State Board 2024 ed.), Chapter 1, p.11.
Archaeologists identify these 'factory' zones by looking for
production indicators: raw materials (like chunks of semi-precious stones), specialized tools (like copper drills), and, most importantly,
waste material. Large quantities of waste or unfinished objects at a site tell us it was a production hub rather than just a place where items were used. For instance, while Mohenjodaro was a massive administrative center, tiny sites like
Chanhudaro were almost entirely devoted to craft production, including bead-making, shell-cutting, and seal-making
THEMES IN INDIAN HISTORY PART I, History CLASS XII (NCERT 2025 ed.), Bricks, Beads and Bones, p.27.
The Harappans were masters of resource management, establishing settlements near the source of specific materials to ensure a steady supply. This strategic geography is summarized in the table below:
| Material |
Primary Site or Source |
Nature of Material |
| Shell |
Nageshwar and Balakot |
Coastal sites specializing in bangles and ladles. |
| Lapis Lazuli |
Shortughai (Afghanistan) |
A highly valued blue stone found near the source. |
| Carnelian |
Lothal (Gujarat) |
A beautiful red stone used extensively for beads. |
| Steatite |
South Rajasthan / North Gujarat |
A very soft stone used for making seals and beads. |
| Copper |
Khetri (Rajasthan) and Oman |
Used for tools like chisels, fishhooks, and mirrors. |
The technological sophistication was remarkable. For example, to make stone tools and blades, they used
Rohri chert — a fine-grained sedimentary rock sourced from the Rohri hills in Pakistan
History, Class XI (Tamilnadu State Board 2024 ed.), Chapter 1, p.12. The variety of materials used — from gold and bronze to terracotta and faience (a high-tech glazed ceramic of the time) — highlights a society with deep technical knowledge and complex trade networks.
Key Takeaway Harappan craft production was a specialized, organized industry where specific sites were dedicated to manufacturing goods based on their proximity to raw materials like shell, stone, and metal.

2. Procurement of Raw Materials for Crafts (intermediate)
To sustain their sophisticated craft industry, the Harappans developed a highly organized system for procuring raw materials, which were often located hundreds of miles away from the main urban centers. Unlike a modern economy that relies on global shipping, the Harappans used two primary strategies:
establishing specialized settlements at the source of the material and
sending long-distance expeditions. For instance, they established
Nageshwar and Balakot in coastal areas specifically for
shell, and
Shortughai in far-off Afghanistan near the best source of
lapis lazuli, a blue stone highly prized by the ancients
Themes in Indian History Part I, Bricks, Beads and Bones, p.12. Similarly,
Lothal served as a gateway for
carnelian from Bharuch and
steatite from South Rajasthan
History, Class XI (Tamilnadu State Board 2024 ed.), p.11.
For materials like copper and gold, the Harappans sent expeditions to regions such as the Khetri area of Rajasthan and South India. These expeditions weren't just about resource extraction; they helped establish communication with local non-Harappan communities, such as the Ganeshwar-Jodhpura culture in Rajasthan. Archaeologists believe this indigenous culture supplied copper to the Harappans in exchange for finished goods Themes in Indian History Part I, Bricks, Beads and Bones, p.12. This suggests a complex web of internal trade and inter-cultural contact within the Indian subcontinent.
The procurement network also extended beyond the borders of the subcontinent. Evidence shows that the Harappans traded for copper with Oman (at the tip of the Arabian peninsula). Scientists have found that both Omani copper and Harappan artifacts contain traces of nickel, proving a common origin Themes in Indian History Part I, Bricks, Beads and Bones, p.13. This international trade is further corroborated by Mesopotamian cuneiform inscriptions that refer to a land called 'Meluhha'—the likely Mesopotamian name for the Indus region—as a source of carnelian, lapis lazuli, gold, and various woods History, Class XI (Tamilnadu State Board 2024 ed.), p.12.
| Material |
Primary Source Site/Region |
| Shell |

| Lapis Lazuli |
Shortughai (Afghanistan) |
| Carnelian |
Lothal (Bharuch, Gujarat) |
| Copper |
Khetri (Rajasthan), Oman |
| Steatite |

3. External Trade and the Global Reach of Harappan Goods (intermediate)
The Harappan Civilization was not a secluded entity; it was a vibrant hub of international commerce. To understand its global reach, we look at both archaeological finds and ancient literature. Mesopotamian cuneiform inscriptions provide a crucial linguistic link, referring to a distant land called "Meluhha," which historians today identify as the Indus region. These texts describe Meluhha as a land of seafarers, a claim supported by the discovery of Harappan seals and weights in places as far-flung as modern-day Iraq (Mesopotamia), Bahrain, and Oman History, class XI (Tamilnadu state board 2024 ed.), Chapter 1, p.12.
The Harappans specialized in high-value, low-bulk luxury goods that were in great demand abroad. Bead-making was perhaps their most sophisticated craft, utilizing exotic materials like Lapis Lazuli (sourced from Badakshan), carnelian, jasper, and gold. While many sites produced these, Chanhudaro stands out as a primary industrial center specifically dedicated to craft production, housing factories with furnaces and tools for every stage of bead manufacture History, class XI (Tamilnadu state board 2024 ed.), Chapter 1, p.11. These finished products weren't just local ornaments; they were key exports that fueled the Harappan economy.

How did they ensure the security of these goods across the Arabian Sea? The answer lies in the Harappan seals. Made primarily of steatite, these seals often featured animal motifs and a script that served as an identity marker. When a merchant sent a bag of goods, a layer of wet clay was applied to the knot and pressed with a seal. If the impression remained intact upon arrival, it proved the contents hadn't been tampered with, indicating both ownership and authenticity THEMES IN INDIAN HISTORY PART I, History CLASS XII (NCERT 2025 ed.), Bricks, Beads and Bones, p.14.
Key Takeaway The Harappan economy was deeply integrated into a maritime "Global South" of the Bronze Age, using specialized crafts like bead-making and standardized sealing systems to facilitate trade with Mesopotamia and the Persian Gulf.

4. Distinctive Archaeological Features of Major Sites (intermediate)
To truly understand the Indus Valley Civilisation (IVC), we must look at each site as a specialized piece of a larger economic puzzle. While major cities like Mohenjo-daro were administrative and residential hubs, other sites were specialized 'industrial zones' or agricultural centers. Archaeologists identify these functions by looking for
assemblages—specific groups of objects like raw materials, tools, and waste products—that point to a particular activity.
One of the most fascinating aspects of Harappan archaeology is
specialized craft production. Sites like
Chanhudaro were tiny (less than 7 hectares) compared to Mohenjo-daro, yet they were almost entirely devoted to crafts like bead-making, shell-cutting, and seal-making. To identify a bead factory, archaeologists look for stones like
carnelian (a beautiful red stone), jasper, and crystal, along with copper, bronze, and gold. The presence of
unfinished objects and
flaking waste at Chanhudaro and
Lothal proves these were production hubs. For example, specialized drills have been found at these sites, and at Chanhudaro, furnaces were used to bake the stones to produce the vibrant red color of carnelian
History, class XI (Tamilnadu state board 2024 ed.), Chapter 1: Early India, p.11.
When we shift our focus to the Harappan countryside, the archaeological signatures change from beads to
agricultural technology. How do we know how they ploughed their fields? We find clues in two forms:
models and
actual remains. In
Banawali (Haryana) and Cholistan, archaeologists discovered
terracotta models of the plough, which suggests that oxen were likely used for tilling the land. However, the most unique discovery is at
Kalibangan (Rajasthan), where an actual
ploughed field from the Early Harappan levels was found. This field featured two sets of furrows at right angles to each other, a sophisticated archaeological 'fingerprint' indicating that the Harappans practiced
double cropping (growing two different crops together)
Themes in Indian History Part I, Bricks, Beads and Bones, p.3.
| Feature | Associated Site(s) | Archaeological Significance |
|---|
| Bead Factories & Furnaces | Chanhudaro & Lothal | Indicates highly specialized craft centers and long-distance trade in luxury materials. |
| Terracotta Plough Models | Banawali & Cholistan | Proof of the use of plough technology in agriculture. |
| Grid Furrowed Field | Kalibangan | Earliest evidence of a ploughed field and the practice of simultaneous cropping. |
Key Takeaway Archaeological sites were not identical; while Chanhudaro was a dedicated craft hub for bead-making, Banawali and Kalibangan provide the primary evidence for Harappan agricultural tools and field patterns.

5. Industrial Hubs: The Bead-Making Factories (exam-level)
In the Harappan world, craft production wasn't just a household chore; it was a highly organized industry. While major cities like Mohenjodaro were administrative centers, smaller settlements like
Chanhudaro (a tiny site of less than 7 hectares) were almost exclusively devoted to manufacturing. This specialization is what archaeologists call 'craft centers,' where beads, seals, and weights were produced for the entire civilization
Themes in Indian History Part I, Bricks, Beads and Bones, p.10. These 'industrial hubs' are identified by archaeologists through the presence of
raw materials (stone nodules, copper ore),
specialized tools (like bronze drills), and most importantly,
waste material. Rejects and stone chips left behind are the most reliable 'fingerprints' of a factory site
Themes in Indian History Part I, Bricks, Beads and Bones, p.11.
The level of technological sophistication in these factories was remarkable. For instance, the beautiful red color of
carnelian beads was not natural; it was achieved by firing yellowish raw material at various stages of production. The process involved a sequence of chipping, flaking, grinding, polishing, and finally, drilling. Excavations at Chanhudaro and
Lothal have even revealed specialized drills designed specifically for these hard stones. Conversely,
steatite, a very soft stone, was often ground into a paste to mold intricate 'micro-beads,' a process that still fascinates modern archaeologists
Themes in Indian History Part I, Bricks, Beads and Bones, p.11.
The variety of materials used in these hubs highlights a massive trade network. Factories utilized everything from local terracotta to exotic
lapis lazuli,
faience (a complex glazed ceramic), and precious metals like gold. This industrial output wasn't just for local use; bead-making industries have even been traced as far south as
Kodumanal in Tamil Nadu, suggesting that these craft traditions were deeply embedded in the subcontinent's early economy
Themes in Indian History Part I, Kings, Farmers and Towns, p.44.
| Process Stage | Description |
|---|
| Material Selection | Using carnelian, jasper, steatite, gold, or shell. |
| Firing | Heating yellow nodules to turn them into red carnelian. |
| Refining | Chipping and flaking the stone into its final form. |
| Finishing | Grinding, polishing, and drilling for stringing. |
Key Takeaway Chanhudaro was a dedicated industrial hub where specialized tools and waste material reveal a highly sophisticated, multi-stage process for mass-producing luxury beads.

6. Solving the Original PYQ (exam-level)
Now that you have mastered the diverse material culture of the Indus Valley, this question tests your ability to link craft specialization to specific geographical locations. You have learned that the Harappans used an incredible array of stones and metals—from lapis lazuli and ivory to carnelian—and that archaeologists identify 'factory sites' by looking for waste flakes, tools, and unfinished objects. This question requires you to move beyond general knowledge and apply that methodology to distinguish between the various industrial hubs of the Mature Harappan period.
To arrive at the correct answer, you must evaluate the site-specific signatures of the civilization. Statements (A), (B), and (C) are all factually accurate: the variety of materials used is well-documented in History, class XI (Tamilnadu state board 2024 ed.), and Chanhudaro is universally recognized as the primary center for bead-making. However, (D) is the correct answer (the false statement) because the specific archaeological evidence of a dedicated structure yielding a massive assemblage of beads in all stages of production is the hallmark of Lothal and Chanhudaro, rather than Banawali. While Banawali is a significant site, it is more famously known for its high-quality barley and unique town planning than as a primary bead-manufacturing hub.
UPSC frequently employs the 'Site-Feature Swap' trap, which is exactly what happens in Option (D). They take a detailed, accurate description of a 'bead factory' and attribute it to the wrong location to test your precision. Options (A), (B), and (C) act as 'distractors' that are true statements, designed to tempt students who might not remember the specific archaeological context of every site. When tackling such questions, always look for the most specialized industrial centers—Chanhudaro and Lothal—when bead factories are mentioned.
