Ancient Civilizations

Thousands of years before you were born, brilliant people built some of the world's greatest cities, invented writing, created governments, and engineered marvels that still amaze us today. These groups are called civilizations — advanced societies with organized governments, cities, laws, and culture. Great civilizations also grew in Mesopotamia (between the Tigris and Euphrates rivers), China (the Great Wall), and the Maya lands of Central America (stepped pyramids and calendars), and this lesson looks closely at three more: Egypt, Greece, and Rome.

Ancient Egypt (3000 BC – 30 BC)

• Ruled by powerful leaders called pharaohs, who were treated as living gods and had complete control over the land and its people.
• Built enormous pyramids as royal tombs — the Great Pyramid of Giza took about 20 years and roughly 20,000 workers to complete.
• Developed hieroglyphs — a writing system using pictures and symbols — and recorded many things on scrolls made from papyrus reeds.
• Depended on the Nile River, which flooded yearly and left behind rich soil perfect for farming.

Ancient Greece (800 BC – 146 BC)

• Organized into independent city-states — Athens, Sparta, and Corinth were among the most powerful.
• Athens invented democracy — a system in which free male citizens voted directly on laws and decisions, a revolutionary idea that shapes governments today.
• Built magnificent temples supported by tall stone columns, and created myths featuring gods, heroes, and monsters to explain the world around them.

Ancient Rome (509 BC – 476 AD)

• Grew from a small city into a vast empire — a large region of many peoples and lands ruled by one powerful leader — stretching from Britain to North Africa.
• Built extraordinary aqueducts — elevated stone channels that carried fresh water from distant mountains into cities, supplying public baths and fountains.
• Created a senate — a council of elected leaders who helped make laws — and a legal system that influenced modern law in many countries.
