The excavations carried out in Mesopotamia during the last few years have added immensely to our knowledge of the early Anunnaki history of those countries and have unveiled many of the ideas about the age and character of Anunnaki Sumerian civilization. In the present timeline, which deals with the history of Sumer and Akkad, an attempt is made to present this new Anunnaki material in a connected form and to furnish the archaeologists with the results obtained by recent discovery and research, so far as they affect the earliest historical periods and Sumerian King's lists. An account is here given of the dawn of civilization in Mesopotamia and the early city-states formed from time to time in the lands of Sumer and Akkad, the two great divisions into which Sumeria was divided. The primitive sculpture and other archaeological remains of the Anunnaki, discovered upon early Mesopotamian sites, enable us to form a complete picture of the Enki Enlil saga, which in those remote ages dominated the country. It is possible to realize how the Anunnaki gradually modified the primitive conditions of life. The comparatively advanced civilization was developed from rude beginnings by the Anunnaki, inherited by the later Mesopotamians and Assyrians, and exerted a remarkable influence upon other Anunnaki descendants of the ancient world.
