First Dynasty of Isin

The Sumerian King List is an ancient stone tablet originally recorded in the Sumerian language, listing kings of Sumer (ancient southern Iraq) from Sumerian and neighboring dynasties, their supposed reign lengths, and the locations of the kingship. Kingship was seen as handed down by the gods, and could be transferred from one city to another, reflecting perceived hegemony in the region. Throughout its Bronze Age existence, the document evolved into a political tool. Its final and single attested version, dating to the Middle Bronze Age, aimed to legitimize Isin's claims to hegemony when Isin was vying for dominance with Larsa and other neighboring city-states in southern Mesopotamia.

The list blends prehistorical, presumably mythical predynastic rulers enjoying implausibly lengthy reigns with later, more plausibly historical dynasties. Although the primal kings are historically unattested, that does not preclude their possible correspondence with historical rulers who were later mythicized. Some Assyriologists view the predynastic kings as a later fictional addition. Only one ruler listed is known to be female: Kug-Bau "the (female) tavern-keeper", who alone accounts for the Third Dynasty of Kish. The earliest listed ruler whose historicity has been archaeologically verified is Enmebaragesi of Kish, ca. 2600 BC. Reference to him and his successor, Aga of Kish, in the Epic of Gilgamesh has led to speculation that Gilgamesh himself may have been a historical king of Uruk. Three dynasties are absent from the list: the Larsa dynasty, which vied for power with the (included) Isin dynasty during the Isin-Larsa period; and the two dynasties of Lagash, which respectively preceded and ensued the Akkadian Empire, when Lagash exercised considerable influence in the region. Lagash in particular is known directly from archaeological artifacts dating from ca. 2500 BC. The list is important to the chronology of the 3rd millennium BC. However, the fact that many of the dynasties listed reigned simultaneously from varying localities makes it difficult to reproduce a strict linear chronology.
