Discovering the Harappan Cities
Part of: Finding and Mapping the Cities
About 4700 years ago, planned cities grew on the plains of the Indus and its tributaries. Harappa and Mohenjodaro were the first two to be excavated in the 1920s, and many more have been found since, from Gujarat to Haryana. Scientists date burnt grain and wood from the digs to fix the mature city period near 2600 to 1900 BCE.
Why it matters. This is the subcontinent's earliest urban phase, so its dates and spread anchor everything studied later. Learning how the dates were fixed also shows that history rests on methods, not guesses.
Key words
- excavation
- : careful digging at an old site to uncover walls, tools and other remains
- stratigraphy
- : reading soil layers so that deeper finds count as older than higher ones
- radiocarbon dating
- : a science test on burnt wood or grain that estimates how old it is
- mature Harappan period
- : the centuries when the cities were at their peak, near 2600 to 1900 BCE
- Survey
- : an official team that maps, records and protects old sites and objects
Try it in two minutes
- Sketch a rough map and mark Harappa in the north and Mohenjodaro to its south.
- Add Lothal in Gujarat and Kalibangan in Rajasthan to show the spread.
- Ask: if deeper layers hold older objects, what should lie at the bottom of a trench?
Try at home. Draw a timeline from 3000 BCE to 1500 BCE and shade the mature Harappan period on it.
Planning Towns and Houses
Part of: Finding and Mapping the Cities
Mohenjodaro was split into a smaller raised western part and a larger lower eastern part, with streets laid out in a rough grid. Houses opened onto lanes, many had their own wells and bathrooms, and covered drains carried waste away. At Mohenjodaro a large watertight tank, the Great Bath, stood in a courtyard with rooms around it.
Why it matters. Town planning shows a society that could organise labour and agree on common rules. Comparing the two parts of the city trains learners to read a settlement map as evidence of social order.
Key words
- grid pattern
- : streets laid out straight so that they cross each other at right angles
- citadel
- : the smaller raised part of a Harappan city with large special buildings
- lower town
- : the larger residential part of the city where most people lived
- Great Bath
- : a large watertight tank at Mohenjodaro probably used for a special ritual bath
- drainage
- : covered channels that carried waste water out of houses and streets
Try it in two minutes
- Draw two rectangles side by side: a small raised one and a big lower one.
- Rule straight crossing streets inside the big rectangle for the grid.
- Ask: where would you place wells and drains so every house can reach them?
Try at home. Walk down your own lane and list three things the street provides, such as water, drainage or lighting, like a Harappan street did.
Crafts, Seals and Distant Trade
Part of: Work, Rank and Decline
Harappan workshops shaped beads from carnelian, cut shell bangles and cast copper tools. Traders used square steatite seals stamped with animals and short sign lines, plus neat chert weights that matched across cities. Goods such as copper from Oman and beads reached Mesopotamia, where records speak of a land called Meluhha.
Why it matters. Craft and trade show how cities fed specialists who did not grow food. Uniform weights and seals reveal rules that let strangers trust each other in exchange.
Key words
- steatite
- : a soft stone carved into square seals stamped with animals and signs
- sealing
- : a clay tag pressed with a seal to mark or secure a packet of goods
- chert weights
- : hard stone weights made in fixed ratios and used across cities
- Meluhha
- : the name in Mesopotamian records for the distant Harappan region
- specialisation
- : workers focusing on one craft, such as bead-making, instead of farming
Try it in two minutes
- List three raw materials: stone for beads, shell for bangles, copper for tools.
- Ask: why would a buyer far away trust a sealed packet?
- Compare two pebbles of different size and ask how fixed weights solve the quarrel.
Try at home. Weigh the same fruit on two kitchen scales and discuss why traders needed one standard set of weights.
Social Differences and the End
Part of: Work, Rank and Decline
Burials at Harappa show some graves with many pots and jewellery while most have little, hinting at differences in wealth. Rare costly objects, such as tiny gold beads, contrast with everyday faience bangles. Around 1900 BCE the cities thinned out: writing and weights faded, and people moved toward villages, perhaps as rivers shifted and rains failed.
Why it matters. This topic teaches caution: no palace or king is proven, so rank must be argued from graves and objects. The many theories of decline show why historians test several causes instead of picking one story.
Key words
- burial goods
- : pots, beads and tools placed with the dead, hinting at differences in wealth
- luxuries
- : rare costly objects, such as gold beads, owned by only a few people
- utilitarian goods
- : everyday useful objects, such as grinding stones and plain pots
- de-urbanisation
- : the thinning of cities as people move back to villages and small towns
- interpretation
- : the meaning historians build from finds, which can change with new proof
Try it in two minutes
- Compare two graves: one with thirty pots, one with two, and ask who may have been richer.
- Sort beads into rare gold-like and common clay-like piles.
- Ask: if a river shifts course, what happens to farms, trade and cities in order?
Try at home. Find one news story that offers two different causes for the same event and note which cause has stronger proof.
