The King List is built around a single dramatic hinge: a great flood divides its antediluvian section, with its handful of kings and vast reign lengths, from a postdiluvian section describing kingship being sent down again, this time landing at the city of Kish, and continuing from there through dynasties whose reign lengths grow steadily more historically plausible the closer the list gets to its own compilation date. This structure places the list's narrative squarely alongside the wider Mesopotamian flood tradition already present on this religion's page as the myth of Utnapishtim, though the King List treats the flood chiefly as a chronological hinge point for the history of kingship rather than telling the flood story itself in any detail.
That the flood could serve as a shared reference point for both a mythic narrative and a supposedly historical king list says something important about how Mesopotamians drew the line, or rather did not draw a hard line, between myth and history. The same event could anchor a story about one family's survival and a document asserting an unbroken chain of divinely sanctioned political authority, because both were understood as true accounts of how the present world had come to be arranged the way it was.
