The Sumerian King List is an ancient manuscript 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 “official” kingship. Kingship was believed to have been 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 with implausibly lengthy reigns with later, more plausibly historical dynasties. Although the primal kings are historically unattested, this does not preclude their possible correspondence with historical rulers who were later mythicized.
