The Sumerian King List or Chronicle of the One Monarchy is an ancient literary composition written in Sumerian that was likely created and redacted to legitimize the claims to power of various city-states and kingdoms in southern Mesopotamia during the late third and early second millennium BC. It does so by repetitively listing Sumerian cities, the kings that ruled there, and the lengths of their reigns. Especially in the early part of the list, these reigns often span thousands of years. In the oldest known version, dated to the Ur III period but probably based on Akkadian source material, the SKL reflected a more linear transition of power from Kish, the first city to receive kingship, to Akkad. In later versions from the Old Babylonian period, the list consisted of a large number of cities between which kingship was transferred, reflecting a more cyclical view of how kingship came to a city, only to be inevitably replaced by the next. In its best-known and best-preserved version, as recorded on the Weld-Blundell Prism, the SKL begins with a number of antediluvian kings, who ruled before a flood swept over the land, after which kingship went to Kish. It ends with a dynasty from Isin, which is well-known from other contemporary sources.

The Early Dynastic period is an archaeological culture in Mesopotamia that is generally dated to c. 2900 – c. 2350 BC and was preceded by the Uruk and Jemdet Nasr periods. It saw the development of writing and the formation of the first cities and states. The ED itself was characterized by the existence of multiple city-states: small states with a relatively simple structure that developed and solidified over time. This development ultimately led to the unification of much of Mesopotamia under the rule of Sargon, the first monarch of the Akkadian Empire. Despite this political fragmentation, the ED city-states shared a relatively homogeneous material culture. Sumerian cities such as Uruk, Ur, Lagash, Umma, and Nippur located in Lower Mesopotamia were very powerful and influential. To the north and west stretched states centered on cities such as Kish, Mari, Nagar, and Ebla.
