The ancient Sumerians, the "black-headed ones," lived in the southern part of what is now Iraq. The heartland of Sumer lay between the Euphrates and Tigris rivers, in what the Greeks later called Mesopotamia. This territory, once skillfully irrigated, proved very fertile, and major cities had long been in existence before the period when archaeologists can identify the Sumerian people themselves.

The Sumerians were characteristically inventive, and are likely to have been responsible for the development of the first writing. Well before 3000 B.C.E. Sumerians were recording their language using simple pictures. They wrote on tablets of clay, later evolving the script that to us is known as cuneiform, or "wedge-shaped."
