Unit 14 — Early Civilizations

Welcome back!

Thousands of years ago, people began forming the world's first civilizations.

Instead of moving from place to place, many people settled near rivers where they could farm, raise families, and build communities.

These early civilizations developed new ideas, inventions, and ways of living that continue to influence our world today.

What Is a Civilization?

A civilization is a society with organized communities, laws, leaders, and shared traditions.

Many civilizations developed:

• cities
• governments
• systems of writing
• trade
• art
• religion
• education

Civilizations allowed people to work together on a much larger scale.

Rivers and Early Settlements

Many of the earliest civilizations grew near rivers.

Rivers provided:

• fresh water
• food
• transportation
• fertile soil for farming

Some famous rivers include:

• the Nile River
• the Tigris River
• the Euphrates River
• the Indus River
• the Yellow River

Reliable water helped communities grow into cities.

Farming Changes Society

Learning to farm changed human history.

People began growing crops and raising animals instead of finding all of their food by hunting and gathering.

As food supplies became more dependable:

• populations increased
• villages grew
• specialized jobs developed
• trade expanded

Agriculture made larger communities possible.

Important Inventions

Early civilizations created many useful inventions.

Examples include:

• writing
• the wheel
• calendars
• irrigation systems
• improved tools
• boats
• early mathematics

These inventions helped people solve problems and improve daily life.

Trade

Communities often produced different goods.

Trading allowed people to exchange items they had for things they needed.

Goods that were traded included:

• food
• cloth
• pottery
• tools
• metals
• spices

Trade also spread ideas and new technologies.

Learning from the Past

Historians study early civilizations by examining:

• artifacts
• buildings
• writings
• tools
• artwork
• fossils

These discoveries help us understand how people lived long ago.

Many ideas that began in early civilizations still influence our lives today.

Activity
