Comparing Ancient River Civilizations Chapter Notes | Social Studies for Grade 7 PDF Download

Introduction

Ancient river civilizations were some of the earliest human societies that grew along the banks of major rivers. These civilizations, including Mesopotamia, Egypt, Indus Valley, and China, depended on rivers for water, food, and transportation. The rivers helped people grow crops, build cities, and create advanced societies. In this chapter, we will learn about the geography and society of these civilizations and explore their achievements and lasting contributions to the world.

Geography and Society

• Mesopotamia: Located between the Tigris and Euphrates rivers in modern-day Iraq.
  • Mesopotamia was called the "Fertile Crescent" because the land was good for farming.
  • The rivers flooded regularly, leaving behind rich soil for growing crops like wheat and barley.
  • People built canals and ditches to control water for farming.
  • Cities like Sumer, Babylon, and Assyria grew along the rivers.
  • Society had kings, priests, farmers, and artisans.
  • People lived in city-states, which were like small countries with their own rulers.
  • Rich people had big houses; poor people had small homes made of mud bricks.
  • Women could own property, but men had more power in society.
• Egypt: Located along the Nile River in modern-day Egypt.
  • The Nile flooded every year, making the soil fertile for crops like wheat and flax.
  • The desert around the Nile protected Egypt from invaders.
  • People built irrigation systems to water their fields.
