Human ancestors and archaeological ages
Long ago, there were many kinds of human ancestors (early relatives of humans). They walked on two legs and slowly learned to use tools. Our own kind is called Homo sapiens (meaning 'wise human'). Homo sapiens appeared in Africa about 3 lakh (300,000) years ago. From Africa, small groups spread to Asia, Europe and other lands. They reached India many tens of thousands of years ago.
There was no writing then. So how do we know? Archaeologists dig carefully and study tools, bones, seeds, pots and paintings. They put the past into archaeological ages based on the main material of tools:
- Stone Age: tools of stone. It has three parts: Palaeolithic, Mesolithic, Neolithic.
- Chalcolithic Age: copper and stone used together (chalco = copper, lithic = stone).
- Bronze Age: bronze, a mix of copper and tin.
- Iron Age: tools and weapons of iron.
These ages did not start on the same day everywhere. One place could still use stone while another used copper.
BCE and CE
BCE means 'Before Common Era'. CE means 'Common Era'. Years in BCE count down towards year 1 CE. So 2500 BCE is older than 1500 BCE.
Palaeolithic, Mesolithic and Neolithic
Palaeolithic (Old Stone Age)
Palaeo means old, lithic means stone. It is the longest age, lasting until about 12,000 years ago. People lived in small moving bands. They were hunter-gatherers: they hunted animals and gathered fruits, roots, nuts and honey. They made big stone tools like hand-axes and choppers. They learned to control fire for heat, light, safety and cooking. In India, sites include the Soan valley, Attirampakkam near Chennai and the Bhimbetka rock shelters in Madhya Pradesh, where people later painted animals and hunting scenes.
Mesolithic (Middle Stone Age)
About 12,000 years ago the Ice Age ended. The climate got warmer, grasslands spread and there were more small animals and fish. People made microliths (micro = tiny): small sharp stone blades fixed on wood or bone to make arrows, sickles and spears. They tamed the dog. Some groups stayed longer at one place. Sites include Bagor in Rajasthan and Adamgarh in Madhya Pradesh.
Neolithic (New Stone Age)
People now made polished stone tools. The big change was farming and keeping animals. Farming meant staying in one place, so people built houses, made pots, and stored grain. Sites include Mehrgarh (in the Bolan area, west of the Indus), Burzahom in Kashmir (pit houses dug in the ground), Chirand in Bihar and ash-mound sites in the south where cattle were kept.
Beginning of farming
Farming began in different parts of the world at different times, about 10,000 years ago in West Asia and a little later in other places. In the Indian subcontinent, Mehrgarh shows farming from about 7000 BCE. People grew wheat and barley and kept sheep, goats and cattle. Rice was grown early in the Ganga valley and the north-east.
Domestication means taming plants and animals and choosing the best ones to grow again. People saved seeds from the strongest plants. They kept calm animals that gave milk, meat, wool or could pull loads.
Why farming changed everything (cause → effect)
- Farming → more food from a small area → more people could live together.
- Crops take months to grow → people settled in one place → permanent houses and villages.
- Extra grain → need to store it → pots, bins and granaries.
- Extra food → not everyone had to farm → potters, weavers, traders and priests appeared.
Historians sometimes call this big change the 'Neolithic revolution', but it happened slowly over thousands of years.
Harappan and contemporary cultures
The Harappan civilisation (also called the Indus or Indus-Sarasvati civilisation) is the first city culture of the subcontinent. Its mature, or full-grown, phase was about 2600–1900 BCE. Cities grew along the Indus and the Ghaggar-Hakra rivers. Important sites are Harappa, Mohenjo-daro, Dholavira, Lothal, Kalibangan and Rakhigarhi.
What made it special
- Town planning: streets in a grid, meeting at right angles. Houses of baked bricks of the same size ratio (about 1:2:4).
- Drains: covered drains along streets, with bathrooms in houses.
- Great Bath at Mohenjo-daro, a big water-tight tank, perhaps for special baths.
- Granaries and warehouses to store grain.
- Seals of stone with animals (like a bull) and a script we still cannot read.
- Standard weights, beads of carnelian, bronze and copper tools, cotton cloth.
- A dockyard-like tank at Lothal and water reservoirs at Dholavira.
Around 1900 BCE, cities slowly declined. Possible reasons: rivers changed course or dried, climate became drier, floods, and trade fell. People moved to smaller villages; the culture did not vanish in one day.
Contemporary cultures (living at the same time)
Not everyone lived in cities. Farming and copper-using village cultures lived side by side, for example the Ahar-Banas culture in Rajasthan (copper tools, black-and-red pots), the Ochre Coloured Pottery culture in the Ganga-Yamuna area, and Neolithic cattle-keepers in the south. Later, Chalcolithic villages in the Deccan such as Inamgaon and Jorwe grew crops and made painted pots.
Mesopotamia, Egypt and China
Like the Harappans, other early civilisations grew next to big rivers. Rivers gave water, fertile silt for farming and an easy way to travel.
Mesopotamia
'Mesopotamia' means 'land between rivers': the Tigris and Euphrates in West Asia. From about 3500 BCE, cities like Uruk and Ur grew here. People built ziggurats (tall stepped temples) and wrote in cuneiform, wedge-shaped marks pressed into clay tablets, from about 3200 BCE. Their texts speak of a land called Meluhha, which most historians think was the Harappan region. Harappan seals and beads have been found there.
Egypt
Egyptian civilisation grew along the Nile. Every year the Nile flooded and left rich soil. Kings called pharaohs ruled. People wrote in hieroglyphs (picture signs) and built pyramids as tombs, like the Great Pyramid at Giza (about 2560 BCE). They also made paper-like sheets from the papyrus plant.
China
In China, early farming villages grew along the Huang He (Yellow River) and the Yangtze. The Shang dynasty (from about 1600 BCE) used fine bronze vessels and wrote on oracle bones, the earliest Chinese writing. The Chinese learned to make silk from silkworms.
What they had in common
- River valley farming with extra grain
- Cities, kings or rulers, and priests
- Writing, trade and crafts like bronze work
Try it
In the last 3D step, move the timeline slider slowly. Predict first: which comes first, pyramids in Egypt or the Harappan Great Bath? Then check. At home: take 10 stones, seeds or buttons. Put 9 in a line for the Palaeolithic and only 1 for all the ages after it. This shows how long people lived as hunter-gatherers compared to farming and cities.
Key formulas and definitions
- Palaeolithic = Old Stone Age: hunter-gatherers, big stone tools, fire
- Mesolithic = Middle Stone Age: microliths (tiny tools), dog tamed
- Neolithic = New Stone Age: farming, polished tools, villages, pots
- Chalcolithic = copper + stone; Bronze = copper + tin
- Harappan mature phase ≈ 2600–1900 BCE
- Mesopotamia (Tigris–Euphrates, cuneiform), Egypt (Nile, hieroglyphs), China (Huang He, oracle bones)
Worked examples
1. Why did people start living in villages in the Neolithic age?
Crops take months to grow and must be watched. So farmers stayed near their fields. They built houses, made pots and stored grain, and houses close together became a village.
2. Put these in order from oldest to newest: Harappan cities, first farming at Mehrgarh, Bhimbetka hunter-gatherers.
Bhimbetka hunter-gatherers (Palaeolithic–Mesolithic) → farming at Mehrgarh (about 7000 BCE) → Harappan cities (about 2600–1900 BCE).
3. How do we know Harappans traded with Mesopotamia?
Harappan-style seals and carnelian beads have been found in Mesopotamian cities, and Mesopotamian texts mention trade with a land called Meluhha.
4. Give two reasons why rivers helped early civilisations grow.
1) Rivers gave water and fertile silt, so farmers grew extra grain. 2) Rivers were easy routes for boats, helping trade.
5. How many years passed between 2600 BCE and 1900 BCE?
Both are BCE, so subtract: 2600 − 1900 = 700 years. This is how long the mature Harappan phase lasted.
Common mistakes
- Thinking all places moved from stone to metal at the same time. Ages began at different times in different regions.
- Thinking 1500 BCE is older than 2500 BCE. In BCE, the bigger number is older.
- Calling the Harappan script 'read'. It has not been deciphered yet.
- Thinking Harappans vanished overnight. Cities declined slowly and people moved to villages.
