In the 26th century BC, Eannatum of Lagash created what was perhaps the first empire in history, though this was short-lived. Later, Lugal-Zage-Si, the priest-king of Umma, overthrew the primacy of the Lagash dynasty in the area, then conquered Uruk, making it his capital, and claimed an empire extending from the Persian Gulf to the Mediterranean. It was during this period that the Epic of Gilgamesh originates, which includes the tale of The Great Flood.
