Mesopotamia civilization characteristics of advanced cities an example
Humans first settled in Mesopotamia in the Paleolithic era. By 14,000 B.C., people in the region lived in small settlements with circular houses.
Five thousand years later, these houses formed farming communities following the domestication of animals and the development of agriculture, most notably irrigation techniques that took advantage of the proximity of the Tigris and Euphrates rivers.
Agricultural progress was the work of the dominant Ubaid culture, which had absorbed the Halaf culture before it.
These scattered agrarian communities started in the northern part of the ancient Mesopotamian region and spread south, continuing to grow for several thousand years until forming what modern humans would recognize as cities, which were considered the work of the Sumer people.
Uruk was the first of these cities, dating back to around 3200 B.C., a mud brick metropolis built on the riches brought from trade and conquest and featuring public art, gigantic columns and temples, and with a population of some 50,000 citizens.
Sumerians are also responsible for the earliest form of written language, cuneiform, with which they kept detailed clerical records.
By 3000 B.C., Mesopotamia was firmly under the control of the Sumerian people. Sumer contained several decentralized city-states—Eridu, Nippur, Lagash, Uruk, Kish and Ur.
