Uruk (Warka)Sumer was an ancient civilization in the fertile region of southern Mesopotamia. Some 6000 years ago, one Sumerian settlement started to grow bigger and bigger: Uruk. By 3200 BC it had turned into the first city of mankind. Up to 50.000 people my have lived around the monumental temples of the Eanna district.
To sustain such a large population, Uruk employed a full-time bureaucracy. The Sumerians began using clay tokens to calculate supplies and goods. In order to simplify the counting, they later replaced the tokens by symbols stamped into clay tablets - mankind's first writing was born.
