Study Material: Timeline and Sources of History

1. What is History?

The word history comes from a Greek word meaning "to inquire" or "to investigate."

History is the study of people, places, events, cultures, and civilizations of the past. It helps us understand how people lived, worked, solved problems, and how the world has changed over time.

History is not just about kings and wars. It also tells us about:

  • Ordinary people's lives
  • Homes and families
  • Food and clothing
  • Farming and trade
  • Art and culture
  • Science and inventions

Why do we study history?

History helps us:

  • Learn from the successes and mistakes of people in the past.
  • Understand how our society developed.
  • Appreciate different cultures.
  • Protect our heritage.
  • Become responsible citizens.

Example:
By studying history, we learn how people invented the wheel, discovered farming, and built the first cities.

2. How Do We Learn About the Past?

We cannot travel back in time. Historians learn about the past by studying evidence left behind by earlier people.

People who study history are called historians.

Historians:

  • Collect evidence
  • Study old objects
  • Read old writings
  • Visit historical sites
  • Compare information from different sources
  • Draw conclusions based on facts

Sometimes historians work with archaeologists.

Archaeologists

Archaeologists study the remains of ancient people by carefully digging the ground.

This careful digging is called excavation.

They discover:

  • Pottery
  • Tools
  • Bones
  • Coins
  • Ornaments
  • Buildings
  • Skeletons

These discoveries help us understand how people lived thousands of years ago.

3. How is Time Measured in History?

History covers thousands and even millions of years.

To understand such long periods, historians divide time into different units.

Time Units

Unit

Meaning

Day

24 hours

Month

About 30 days

Year

12 months

Decade

10 years

Century

100 years

Millennium

1000 years

Examples

  • 10 years = 1 decade
  • 100 years = 1 century
  • 1000 years = 1 millennium

BC and AD

Years are divided into two parts.

BC (Before Christ)

These are the years before the traditional birth year of Jesus Christ.

Example:

  • 500 BC
  • 1200 BC

In BC, numbers become smaller as time moves forward.

Example:
500 BC → 400 BC → 300 BC → 200 BC → 100 BC

AD (Anno Domini)

"Anno Domini" means "In the Year of the Lord."

These are the years after the birth of Jesus Christ.

Example:
AD 200
AD 500
AD 2026

The numbers become larger as time moves forward.

BCE and CE

Today many historians use:

  • BCE = Before Common Era
  • CE = Common Era

These mean the same as BC and AD but are religiously neutral.

4. Timeline

A timeline is a straight line that shows important events in the order in which they happened.

Timelines help us understand:

  • Which event happened first
  • Which event happened later
  • How much time passed between events

Example Timeline

10,000 BCE      8,000 BCE       3,000 BCE        2026 CE     |---------------|---------------|---------------| First farming    First villages    Early cities    Today

 

Another Example

Birth → School → College → Job

 

This is also a timeline because events are arranged in order.

Why are Timelines Important?

They help us:

  • Arrange events correctly.
  • Understand the passage of time.
  • Compare events.
  • Remember historical events easily.

5. What are the Sources of History?

Anything that gives us information about the past is called a source of history.

Historians use many different sources.

They are mainly divided into:

  1. Archaeological Sources

6. The Beginning of Human History

Human history began millions of years ago.

The earliest humans lived in forests and open grasslands.

They were called hunter-gatherers because they:

  • Hunted animals.
  • Gathered fruits, nuts, roots, and seeds.

They did not have permanent homes.

They moved from place to place searching for:

  • Food
  • Water
  • Safety

Early Humans

Early humans:

  • Lived in caves.
  • Used simple stone tools.
  • Wore animal skins and leaves.
  • Lived in groups.
  • Used fire for warmth and cooking.

Fire was one of the greatest discoveries in human history.

It helped people:

  • Cook food
  • Keep wild animals away
  • Stay warm
  • See at night

Stone Age

The Stone Age is the earliest period of human history.

It is divided into:

1. Old Stone Age (Palaeolithic)

People:

  • Hunted animals
  • Gathered food
  • Used rough stone tools
  • Lived in caves

2. Middle Stone Age (Mesolithic)

People:

  • Used smaller tools
  • Began domesticating animals
  • Started living in temporary shelters

3. New Stone Age (Neolithic)

People:

  • Learned farming
  • Built permanent houses
  • Kept animals
  • Made pottery

This period marked the beginning of settled life.

7. The First Crops

Around 10,000 years ago, humans discovered farming.

This changed human life forever.

Instead of moving from place to place, people settled near rivers.

Why Did Farming Begin?

People observed that seeds falling on the ground grew into new plants.

They began planting seeds deliberately.

Early Crops

Some of the first crops were:

  • Wheat
  • Barley
  • Rice
  • Millet
  • Lentils
  • Peas

Domestication of Animals

People also tamed animals.

Early domesticated animals included:

  • Dogs
  • Goats
  • Sheep
  • Cattle

Animals provided:

  • Milk
  • Meat
  • Wool
  • Help in farming
  • Protection

Advantages of Farming

Farming helped people:

  • Produce more food.
  • Build permanent homes.
  • Form villages.
  • Increase population.
  • Develop trade.
  • Start civilizations.

From Villages to Civilizations

As farming improved:

  • Villages grew larger.
  • People built houses.
  • Different occupations developed.
  • Trade began.
  • Writing was invented.
  • The first civilizations emerged near rivers.

Examples:

  • Indus Valley Civilization
  • Egyptian Civilization
  • Mesopotamian Civilization
