The sixth Amorite king of Sumer, Hammurabi, is born about this time. He is known for the Code of Laws, but he also vastly extends the empire based in Babylon. From this time and for many centuries thereafter, the Mesopotamian region is properly referred to as Babylonia instead of Sumeria. See also 1900 bce Archaeology; 1366 bce Archaeology.
CommunicationThe wedge-shaped point on the stylus used for inscribing pictographs on clay tablets has by this time changed the writing style in Mesopotamia to an early form of cuneiform (which means "wedge-shaped"). The pictographs have become very stylized and might more properly be called ideograms. See also 3000 bce Communication; 1500 bce Communication.
