Between two rivers in Mesopotamia, farming surpluses let people gather into the world's first cities — and to track the grain, they invented writing. The first cities and the first written words were born together.
Where cities began
The first cities grew in Mesopotamia — the 'land between rivers', the Tigris and Euphrates — around 5,000 years ago. Reliable farming there produced a food surplus, which freed some people to become priests, traders, and craftsmen. To track stored grain and trade, the Sumerians invented one of the first writing systems, cuneiform.
Writing let people record laws, debts, and stories across time — knowledge no longer died with the person who held it.
- A village's farms produce more grain than the farmers need.
- What new jobs can now exist, since not everyone must farm?
- Why would this society need writing?
What you should see: Surplus food frees people for specialized roles — priests, traders, builders — and writing arises to record the growing web of goods, debts, and rules.
