What Was the First Civilization?
Long before the pyramids of Egypt, the Roman Empire, or the great cities of the medieval world, human societies were already beginning to transform the landscape.
One of the most important transformations took place in southern Mesopotamia, the fertile region between the Tigris and Euphrates rivers, in what is now southern Iraq.
Here, the civilization known as Sumer emerged and developed some of the earliest known cities, administrative systems, monumental buildings, and writing. Britannica describes Mesopotamia as the home of the world’s earliest civilization, while historical scholarship commonly identifies Sumer as the earliest known civilization within Mesopotamia.
1. The Land Between Two Rivers
The name Mesopotamia comes from a Greek expression meaning “between rivers.”
The Tigris and Euphrates provided water for agriculture and helped communities establish permanent settlements. Over time, irrigation and agricultural production created food surpluses, allowing populations to grow and specialized occupations to develop.
This changed human society.
People were no longer living only in small farming villages.
They began building increasingly large settlements.
And eventually, something extraordinary appeared:
the city.
2. The Rise of Uruk
Among the most important early cities was Uruk.
During the fourth millennium BCE, Uruk became one of the world’s earliest major urban centres. Archaeological evidence shows monumental buildings, organized administration, craft production, and increasingly complex economic systems.
Uruk became so important that the period associated with its expansion is commonly called the Uruk Period, roughly 4000–3100 BCE.
At its height, this was no simple village.
There were temples, workshops, administrative buildings, homes, markets, and enormous numbers of people living and working together.
3. The Birth of Writing
Perhaps Sumer’s most famous achievement was writing.
Around the late fourth millennium BCE, people in southern Mesopotamia began recording information on clay tablets. Early records were heavily connected with administration, goods, quantities, and economic transactions.
These markings eventually developed into cuneiform, one of the world’s earliest known writing systems. Evidence places the emergence of genuine writing in Sumer around 3000 BCE or earlier.
A simple clay tablet could record something that otherwise might have been forgotten.
Grain.
Animals.
Trade.
Workers.
Payments.
And eventually, laws, literature, religion, and history.
4. More Than One City
Sumer was not a single unified country in the modern sense.
By the third millennium BCE, southern Mesopotamia contained numerous city-states, including:
- Uruk
- Ur
- Lagash
- Kish
- Nippur
- Larsa
- Umma
Each city had its own political institutions, religious traditions, and surrounding territory.
These city-states sometimes traded with one another.
And sometimes they went to war.
5. How Did Civilization Begin?
The story was not simply about one invention.
Agriculture created food surpluses.
Surpluses supported larger populations.
Larger populations required organization.
Organization encouraged administration.
Administration created a need for record keeping.
And record keeping eventually helped produce writing.
This combination of agriculture, cities, institutions, religion, trade, technology, and writing created what historians recognize as an early civilization.
6. Was Sumer Really the First Civilization?
This question needs some caution.
Sumer is commonly identified as the earliest known civilization, but human civilization did not suddenly appear overnight.
The Ubaid culture, which preceded the mature Sumerian urban civilization, had already established important settlements and agricultural practices in southern Mesopotamia. Some settlements in Mesopotamia became urban centres over long periods of development.
And Mesopotamia was not the only region where complex societies eventually developed.
Ancient Egypt, the Indus Valley, China, and other regions independently developed large-scale civilizations.
So perhaps the better question is:
When did humans first begin living in organized, urban, complex societies?
And one of the earliest answers takes us back more than 5,000 years — to Sumer.

The cuneiform image is particularly useful because writing is one of the strongest visual elements for this article. National Geographic notes that early Sumerian merchants used clay tablets to record goods, with the script developing into cuneiform.
