Mesopotamia or the Sumerian civilization is, alongside ancient Egypt, the most ancient of known
civilizations.
Originally settlements were in the north of the Tigris-Euphrates plain where there was more abundant
rainfall but, as rainfall declined, settlements moved south into the plains. This meant that co-operative
effort was needed to irrigate the fields and so a civilization began to grow in that region.
In about 3000 BC the Sumerians had begun to build cities and, during the following millennium, invented
a phonetic alphabet which they wrote in wet clay tablets, using a reed pen.
POLITICS
The earliest Sumerians governed themselves in city-states by means of a Council of Elders, a general
assembly of all free adult males. That was soon replaced by a dictatorial monarchy.
The Sumerians, however, did not have the lengthy periods of peace which characterised the Egyptian
civilization. Mesopotamia was open to attack from all sides, especially by the nomads from the north and
west.
In that way the territory was over-run in about 2300 BC by Sargon, a Semite from the north, who fused
his own kingdom with Sumeria.
Conflicts between the city-states themselves were also common. In such fashion the city of Ur
(Abraham's hometown) came to rule in about 2000 BC. Later the territory was conquered by the
Babylonians (under Hammurabi), then by the Assyrians (under Tiglath-Pileser), then once again by the
Babylonians (under Nebuchadnezzar).
Each conqueror adopted the useful features of the Mesopotamian civilization so that, although the rulers
changed, the civilization continued and reached its full-flowering under the Babylonians in about 600 BC,
with the famous Hanging Gardens of Babylon.
Ultimately, in about 529 BC, the Mesopotamian civilization fell before the invasion of the forces of another
civilization, the Persians under Cyrus the Great.
SCIENCE
The emergence of the Mesopotamian civilization depended on the development of science for the
drainage of the fertile but swampy river plains and the construction of the cities and temples. In the
process, the people learnt to obey rules and developed administrative, engineering and mathematical
skills.
RELIGION
Hand in hand with science went religion which lay at the centre of Mesopotamian life. Every human
activity was subordinated to some religious purpose. As such the cities of Mesopotamia became sacred
communities serving divine masters, with the temples and the priests dominating human life.
Indeed, the temples were the integral part of the city, owning most of the land, and most of the
townspeople worked in some way or other for the priests. Even science tended to be subordinated to
religion.
CODIFIED LAW
Law was an integral part of the control of society and Mesopotamia was the first to codify its law into
written form, the Code of Hammurabi. The law secured family life through penalties for adultery, and
controlled property through penalties for thieving, lying and murder.
The law also maintained the existence of class-distinction through unequal penalties which were imposed
according to status.
EDUCATION & ART
The evolution of a money economy was accompanied by the development of leisure time. That in turn
saw the growth of education, art and literature. The earliest forms of writing (clay tablets) are from the
Mesopotamian era, with the Epic of Gilgamesh probably forming the basis for the later Biblical stories of
creation and the flood.
The Mesopotamians also gave birth to mathematics and medicine as distinct schools of learning.
