The Beginnings of Indian Civilisation

Chapter 6 · Social Science · Class 6 24 min read

Why This Matters

Look around your town or city. There are streets. There are houses. There are shops and a market. There are drains under the road that carry dirty water away. Somebody planned all of this.

Now here is a surprise. People in India were doing the very same thing more than 4,500 years ago.

That is a very long time ago. Think of it like this. Your grandparents are old. Their grandparents are older. Go back and back and back, about 180 great-great-grandparents in a row. That is how far back we are talking.

Back then, people built whole cities. The streets were straight. The drains ran neatly under the roads. The houses were made of baked bricks. This was one of the first great civilisations in the whole world. And it grew right here, in our part of the world.

In this chapter, we will go on a journey back in time. We will see how people stopped wandering and learned to farm. We will see how small villages slowly grew into busy cities. And we will visit the amazing Harappan cities and find out what made them so special.

The Big Idea

Long ago, humans wandered from place to place, hunting animals and gathering wild fruit. Then came one huge change — people learned to farm, that is, to grow their own food and keep animals. Because they now had food in one spot, they could stop wandering and settle down. Small villages grew. Some villages grew into towns, and some towns grew into great cities. When a society becomes this advanced — with planned cities, rulers, crafts, trade and writing — we call it a civilisation. India’s first great civilisation was the Harappan (also called the Sarasvati–Sindhu civilisation). Its people built clean, well-planned cities that still amaze us today.

Let’s Break It Down

We will build the story step by step. First, the big change from hunting to farming. Then villages. Then the great cities. Let us begin.

From hunter-gatherers to farmers (the Neolithic change — and WHY farming changed everything)

For most of human history, people did not grow food. They went out and found it.

A hunter-gatherer is a person who lives by hunting wild animals and gathering wild plants, fruits and nuts. (“Gather” just means to collect, like gathering mangoes that have fallen from a tree.) These early people did not have farms or shops. They ate whatever nature gave them.

This kind of life had one big problem. The food in one place soon ran out. The animals moved away. The fruit trees stopped giving fruit. So the people had to move too. They were always on the move, looking for the next meal. They could not stay in one place for long.

Then, slowly, over many years, people noticed something. A seed that falls on the ground grows into a new plant. If you plant seeds on purpose, you can grow your own food!

This was a giant discovery. People learned to:

  • grow crops (plant seeds and harvest the food), and
  • keep animals (like cows and goats, instead of hunting them in the wild).

This big change — from finding food to growing food — is called the start of farming, or agriculture. (“Agriculture” is just a bigger word for farming.) Historians call this whole change the Neolithic change. You do not need to remember that word. Just remember what it means — the time when humans learned to farm.

Figure 6.1 below shows this big change side by side.

On the left, hunter-gatherers wander, hunt a running animal with a spear and gather wild berries; they have no fixed home and move when food runs out. A blue arrow in the middle marked Neolithic change shows people learning to farm. On the right, farmers settle in one place with houses, grow their own crops and keep animals together in a village.
Figure 6.1 — The big change from hunters to farmers. Panel (a) on the left shows hunter-gatherer life: a person hunts a wild animal with a spear, and there are wild berries to gather. These people had no fixed home and had to move when the food ran out. The blue arrow in the middle is the Neolithic change — the time when people learned to farm. Panel (b) on the right shows the new farming life: people build fixed houses, grow their own crops in a field, and keep animals like cows close by. Now they could all live together in one place — a village.

Now the most important question. Why did farming change everything? Why was this such a big deal?

Here is the reason, step by step. When you grow your own food, the food stays in one place — your field. You do not need to chase it. So you do not need to keep moving. You can build a proper house and stay. And once people stay in one place, more good things follow:

  • They can store extra grain for later.
  • They can have more children, because food is steady.
  • Many families can live close together. That makes a village.
  • Not everyone has to grow food. Some people are now free to do other jobs — make pots, weave cloth, build houses.

So farming did not just give people food. It gave people a settled life. And a settled life is what made villages, towns, crafts and cities possible. That one change started everything else in this chapter.

Let us compare the two ways of living clearly. This will make the difference stick in your mind.

QuestionHunter-gatherer lifeFarming / settled life
Where did they get food?Hunted wild animals and gathered wild plantsGrew their own crops and kept animals
Did they stay in one place?No — they kept moving to find foodYes — they settled down near their fields
What kind of home?Temporary shelters, often a cave or a hutProper houses, sometimes of brick
Could they store food?Hard to store much while movingYes — they could store extra grain
Could people do other jobs?Almost everyone had to find foodSome were free to make pots, cloth, tools
Did villages form?No fixed villagesYes — many families lived together
Concept check

Why could people settle down and stay in one place only AFTER they learned to farm, and not before?

The first villages

So farming gave us the first villages.

A village is a small group of homes where people live close together. Their fields are nearby. They share the land, water and work.

In India, from about 3500 BCE, many villages grew in the north-west. (“BCE” means Before our era — it counts years going backwards from a fixed point. So 3500 BCE is older than 2000 BCE. The bigger the BCE number, the longer ago it was.)

These villages had a good spot. They grew along rivers. Why rivers? Three simple reasons:

  1. Water. People, animals and crops all need water. A river gives water all year.
  2. Rich soil. When a river floods, it leaves behind a layer of fresh, soft mud. This mud is full of goodness for plants. So crops grow well near rivers.
  3. Easy travel. People could move and carry goods on boats along the river.

Two great rivers mattered most here. One was the Indus (also called the Sindhu). The other was the Sarasvati, which flowed nearby long ago. Sadly, the Sarasvati river later dried up. Today only a small seasonal stream is left where it once flowed.

Over hundreds of years, something wonderful happened. Some villages got bigger. They became towns. A few towns grew even more. They became busy cities. This big jump — from villages to cities — happened around 2600 BCE. It was India’s first time having proper cities. Historians even call it the First Urbanisation of India. (“Urban” just means to do with towns and cities.)

The Harappan (Sarasvati–Sindhu) cities — town planning, drainage, Great Bath, granaries

Now we reach the most exciting part. The great cities.

This civilisation has several names. People call it the Harappan, the Indus, or the Sarasvati–Sindhu civilisation. Why so many names? It is named after the rivers it grew along, and after the first city to be dug up. That first city was called Harappa, found about 100 years ago (in 1920–21). So the people are called Harappans, and we will use all the names.

Let us first see when and where this civilisation lived, so the whole story has a clear place and time.

Figure 6.2 below places the civilisation on a timeline, so you can see how long it lasted.

A timeline from 4000 BCE on the left to 1000 BCE on the right. A green band marks villages growing from about 3500 BCE. An orange band marks the great cities, the high point, from about 2600 BCE to 1900 BCE. After 1900 BCE a dashed arrow shows the cities slowly being left empty.
Figure 6.2 — A timeline of the Harappan civilisation. Older time is on the left, newer time is on the right. The green band shows villages growing from about 3500 BCE. The orange band is the high point — the great cities — which lasted from about 2600 BCE to about 1900 BCE, around 700 years. After 1900 BCE, the grey dashed arrow shows the cities slowly being left empty as the civilisation declined.

Now let us see where these cities were. They spread over a huge area in today’s north-west India and Pakistan.

Figure 6.3 below is a simple map. Notice how the cities sit right along the rivers.

A simple map of north-west India and Pakistan. Brown mountains are at the top and left. Two rivers flow down to the sea: the solid blue Indus or Sindhu, and the dashed Sarasvati which is now dry. Red dots mark cities along the rivers: Harappa and Mohenjo-daro near the Indus, and Kalibangan, Rakhigarhi and Dholavira near the Sarasvati and the coast.
Figure 6.3 — A map showing where the main Harappan cities grew. The brown shapes are mountains. The solid blue line is the Indus (Sindhu) river; the blue dashed line is the Sarasvati river, which is now dry. Each red dot is an important city. Harappa and Mohenjo-daro sit along the Indus. Kalibangan and Rakhigarhi lie in the Sarasvati area. Dholavira is near the coast in Gujarat. Notice how every city is close to a river — because rivers gave water, rich soil and easy travel.

So what made these cities so special? The answer is one phrase: town planning.

Town planning means the city was carefully designed before it was built. Nothing was random. Someone thought it all out — where the streets would go, where the houses would sit, where the water would flow.

Here is what a Harappan city had.

Streets in a grid. The streets were wide and straight. They crossed each other at right angles (square corners), like the lines on a chessboard or a sheet of graph paper. This neat criss-cross pattern is called a grid.

Two parts to the city. Most cities had two areas. There was an upper town, built higher up on a raised mound. This part is often called the citadel. The important people probably lived here. Then there was a lower town, where most ordinary people lived. (Dholavira even had three parts, not two.)

Brick houses. Houses were made of bricks. Big house or small house, the bricks were made carefully and the building quality was good. Many houses even had their own bathroom — quite something for 4,000 years ago!

The Great Bath. In the city of Mohenjo-daro, there is a famous large tank called the Great Bath. It was a big pool made of bricks, about 12 metres by 7 metres. The bricks were coated with a special material so the water would not leak out. It had steps going down and small rooms around it. We are not fully sure what it was for. It may have been used for special bathing during festivals or religious events.

Granaries. A granary is a large building used to store grain (like wheat and barley). After the harvest, extra grain could be kept safely here. This is a clear sign of good planning — they saved food for later and for hard times.

Figure 6.4 below shows a plan of a Harappan city, with all these parts marked.

A plan of a Harappan city seen from above. On the left is the raised citadel or upper town with the Great Bath, a big brick water tank, and a granary, a store for grain. On the right is the lower town where most people lived, with wide straight streets crossing at right angles in a grid, brick houses in red, and a covered drain running hidden under one street.
Figure 6.4 — A plan of a Harappan city, seen from above. On the left is the citadel, the upper town, built higher on a mound. It holds the Great Bath, a big brick water tank, and the granary, where grain was stored. On the right is the lower town, where most people lived. The wide grey strips are straight streets that cross at right angles, making a grid like a chessboard. The red blocks are brick houses lining the streets. The blue dashed line is a covered drain that runs hidden under the street to carry away dirty water.

Now, the most impressive part of all — drainage.

A drain is a small channel or pipe that carries away dirty water and waste. Drainage is the whole system of drains in a place.

The Harappans cared a lot about cleanliness. Dirty water from houses flowed into drains. These drains ran neatly under the streets, hidden below. They carried the waste water out of the city. The drains were even covered with bricks or stone slabs, so the streets stayed clean.

Stop and think about how clever this is. Many cities in the world did not have good drains even a few hundred years ago. But the Harappans had covered drains under their streets 4,000 years ago. That is why people say the Harappans had a very high “civic sense” — they cared about keeping their shared city clean.

The Harappans were also brilliant at water management — making sure everyone had enough water. In Mohenjo-daro, people dug hundreds of wells made of bricks. In Dholavira, which was in a dry area, they built huge reservoirs. A reservoir is a big tank or pond made to store water. Dholavira’s largest reservoir was 73 metres long — longer than many school grounds! They even cut some reservoirs straight into the rock.

Crafts, trade & seals

The Harappans were not just good builders. They were also skilled makers and busy traders.

Crafts. A craft is the skill of making things by hand. A craftsperson is someone who makes such things. The Harappans made many beautiful objects:

  • Beads from a pretty reddish stone called carnelian. They had a special trick to drill a tiny hole through each bead so a thread could pass through. Then the beads became a necklace.
  • Bangles from sea shells. Working with hard shell is very tricky, but they managed it.
  • Pots from clay.
  • Tools and toys from copper and a metal called bronze.

Here is a nice “nothing is a given” fact. Where did bronze come from? Copper alone is soft. But the Harappans found that if you mix a little tin into copper, you get bronze, which is much harder. Harder metal makes better tools. So they did not just use what they found — they improved it by mixing metals. Clever, isn’t it?

Trade. Trade means buying, selling and exchanging goods. The Harappans traded a lot. They traded inside their own land, city to city. They also traded with faraway places, even other countries. They sent out things like ornaments, cotton cloth and beads. In return they got things like copper.

To do this trade, they used roads, rivers and even the sea. Boats carried goods to distant lands. In fact, this was India’s first big sea trade. At a place called Lothal in Gujarat, there is a huge brick basin. Many believe this was a dockyard — a place where boats came in to load and unload goods.

Seals. Now for one of the most famous Harappan objects — the seal.

A seal is a small stamp. Harappan seals were tiny squares of stone, only a few centimetres wide. On each seal there are two things: a row of writing signs at the top, and a carved animal below (often a one-horned bull called a “unicorn,” or a bull or an elephant).

What were seals for? Most likely, they were used in trade — like a name-tag. A trader would press the seal into a lump of soft clay on a bag of goods. The mark showed whose goods they were. Clever and simple.

Here is the mysterious part. The writing on the seals has never been read. Nobody today knows what those signs say. The Harappan script is still a puzzle that no one has solved!

Figure 6.5 below shows what a Harappan seal looks like.

A Harappan seal. It is a small square stone stamp. At the top is a row of writing signs that nobody can read today. Below the signs is a carved one-horned bull, called a unicorn, with a small object in front of it. Traders pressed such seals into soft clay to mark their goods.
Figure 6.5 — A Harappan seal — a tiny square stone stamp, only a few centimetres wide. The row of marks along the top is the Harappan writing, which no one today has been able to read. Below the writing is a carved animal, here a one-horned bull that people call a unicorn, with a small object in front of it. Traders pressed the seal into soft clay to leave a mark on their goods, much like a name-tag showing whose goods they were.

What makes something a “civilisation”

We have used the word civilisation many times. Now let us pin down what it really means.

A civilisation is an advanced stage of human society. It is much more than a single village. It usually has several special features all together. Here are the main ones, in simple words:

  • Cities and town planning — proper cities, planned with streets, water and drains.
  • Some kind of government — rulers or leaders to organise everyone and run things.
  • Many crafts — skilled people making pots, jewellery, tools and cloth.
  • Trade — exchanging goods, both nearby and far away.
  • Some form of writing — to keep records and pass on messages.
  • A strong farming system — enough food to feed not just villages but whole cities too.
  • Shared ideas and culture — common beliefs, art and customs that people share.

When a society has all these together, we call it a civilisation. And the Harappans had every single one. That is why they were one of the first great civilisations in the world — alongside ancient Egypt and Mesopotamia (in today’s Iraq).

Let us practise thinking like a historian. Historians read tiny clues to understand the past. Here is how it is done.

Reading a clue from the past

Diggers find hundreds of brick-lined wells and covered drains all over the city of Mohenjo-daro. What does this single clue tell us about the people who lived there?

Why is 'some form of writing' counted as a sign of a civilisation?

Its decline

Nothing lasts forever. After about 700 years of glory, the Harappan cities began to fade away. This started around 1900 BCE.

The word for this slow ending is decline. To decline means to slowly become weaker or smaller. (Like a battery slowly running down — not switched off all at once, but fading bit by bit.)

The cities were left empty, one by one. People did not vanish. They simply moved out of the cities and went back to living in small villages, farming the land. The grand city life ended, and a simpler village life returned.

What caused this decline? Here is an important point. For a long time people thought maybe an army attacked and destroyed the cities. But there is no sign of any war. The Harappans do not seem to have kept armies or war weapons. They seem to have been a fairly peaceful people.

So if not war, then what? Historians today agree on two main reasons, and both are about nature and climate:

  1. The weather changed. From around 2200 BCE, much of the world grew drier. There was less rain. Less rain means less water for crops. Less water means less food. And cities need a LOT of food.
  2. The Sarasvati river dried up. Cities that depended on this river suddenly lost their water. They had to be left behind.

Here is the deeper lesson. Why did losing water hurt the cities so badly? Because cities cannot grow their own food inside the city walls. They depend on villages and farms to send in food every single day. When the water failed, the farms failed. When the farms failed, the food stopped reaching the cities. And a city with no food cannot survive. So the people had no choice but to go back to the villages, close to the land and water.

This reminds us of something true even today. Big cities still depend on water, good weather and farms in the countryside. We are never as separate from nature as we think.

And there is good news at the end. Even though the cities ended, the Harappans’ culture and skills did not all die. Many of their ideas and crafts were passed on to the people who came after them. So the story did not stop. It simply moved on to a new chapter of India’s history.

Common Mistakes

Here are some easy slip-ups students make about this topic. Read them once and you will not be fooled.

⚠️ Common mistake
What students think

The Harappan civilisation is called the 'Indus Valley' civilisation, so it only grew along the Indus river.

Why it seems right

The old name 'Indus Valley' was used for many years and is still printed in lots of books, so it sticks in our minds and sounds like the whole story.

What actually happens

The civilisation spread far beyond the Indus valley. Many cities, like Dholavira and Kalibangan, grew along the Sarasvati river and near the coast, hundreds of kilometres from the Indus. That is why we now call it the Harappan or Sarasvati–Sindhu civilisation, not just 'Indus Valley'.

⚠️ Common mistake
What students think

The Harappan cities must have been destroyed in a big war or invasion.

Why it seems right

In stories and films, great cities almost always fall because an enemy army attacks them, so we expect the same here.

What actually happens

There is no sign of war at all — no weapons of war, no army, no battle damage. The cities declined slowly because of natural changes: the weather grew drier and the Sarasvati river dried up, so there was not enough water and food to keep the cities going.

⚠️ Common mistake
What students think

We can read the Harappan seals, so we know exactly what they say.

Why it seems right

We can clearly see the carved animals and the rows of signs, and seeing writing makes us assume someone must have figured out the words by now.

What actually happens

Nobody has been able to read the Harappan script. We can see the signs, but no one knows what they mean. It is still one of history's unsolved puzzles. We only guess that the seals were used in trade, like name-tags.

Challenge

The Harappans seem to have been peaceful — there is no sign of war weapons or armies. Yet they built huge reservoirs, long covered drains, and whole planned cities. How could they do such giant building work without an army to force people? What does this suggest about how their society worked?

Summary

Here is everything you can now explain to a friend:

  • Long ago, humans were hunter-gatherers — they wandered about, hunting wild animals and gathering wild plants.
  • The huge change came when people learned to farm — to grow their own crops and keep animals. This is called the Neolithic change.
  • Because the food now grew in one place, people could settle down. This led to the first villages.
  • Villages grew along rivers (the Indus/Sindhu and the Sarasvati), because rivers gave water, rich soil and easy travel.
  • Around 2600 BCE, towns grew into the great Harappan (Sarasvati–Sindhu) cities, like Harappa, Mohenjo-daro and Dholavira.
  • These cities had amazing town planning — grid streets, brick houses, the Great Bath, granaries, and clever covered drains and reservoirs for water.
  • The Harappans were skilled at crafts (beads, bangles, pots), busy in trade (even by sea), and used small stone seals with writing we still cannot read.
  • A civilisation has cities, government, crafts, trade, writing, strong farming and shared culture — and the Harappans had them all.
  • The civilisation declined around 1900 BCE, mainly because the climate grew drier and the Sarasvati river dried up — not because of any war.

What’s Next

You have seen how India’s first great cities rose and faded. But the Harappans left behind much more than ruins. Their ideas, beliefs and customs were passed on to the people who came after them.

In the next chapter, Chapter 7 — India’s Cultural Roots, we will dig into those deep roots. We will meet the early ideas, traditions and stories that began long ago and still shape India today. The journey through India’s past continues!

Frequently Asked Questions

What was the Harappan Civilisation and how old is it?

The Harappan Civilisation, also called the Sarasvati-Sindhu or Indus Valley Civilisation, was one of the world's first great city-building cultures. It started around 2600 BCE, which is more than 4,500 years ago. It stretched across a huge area of present-day India and Pakistan along the Indus and Sarasvati river valleys.

What were the special features of Harappan cities like Mohenjo-daro and Harappa?

Harappan cities had straight streets laid out in a grid pattern, well-built brick houses, and an amazing underground drainage system. There was a Great Bath (a large public tank for bathing), granaries to store grain, and workshops for crafts. The level of planning shows these were very advanced cities.

How did early humans change from hunter-gatherers to farmers?

Early humans (hunter-gatherers) moved from place to place hunting animals and collecting wild plants for food. Over thousands of years, they discovered that they could plant seeds and grow their own food. This is called the Neolithic Revolution. Once they could grow food, they stayed in one place, built permanent homes, and villages slowly grew.

What were the Harappan seals and what were they used for?

Harappan seals were small flat tablets made of stone, with pictures of animals and a script carved on them. Traders used them like a stamp or signature to mark goods. The pictures included animals like a one-horned bull called a unicorn. The Harappan script on the seals has not been fully decoded yet.

What is the difference between a hunter-gatherer and a settled farmer?

A hunter-gatherer has no fixed home and moves around to find food by hunting animals and picking wild fruits or roots. A settled farmer stays in one place, grows crops on the same land each season, and keeps animals. Settled farming led to villages, then towns, then cities, because a steady food supply meant more people could live together.
