Tigris-Euphrates Civilization. This civilization originated in the valley of the Tigris and Euphrates rivers in a part of the Middle East called Mesopotamia. It was one of the few cases of a civilization that started from scratch—with no examples from any place available for imitation. This civilization progressed mostly due to the accomplishments of the Sumerians, the most influential people in the Tigris-Euphrates region. By about 3500 B.C.E, the Sumerians had developed the first known human writing, cuneiform. They also were characterized by the development of astronomical sciences, intense religious beliefs, and tightly organized city-states. The Sumerians improved the region’s agricultural prosperity by learning about fertilizers and using silver to conduct commercial exchange.
