Cuneiform law
Cuneiform law is generally classified separately from later Middle Eastern law, but has been viewed as a predecessor of Biblical and Jewish law. The communities of the Middle East that made use of cuneiform law were generally all in contact with one another, and developed similar cultures. Akkadian, a cuneiform language, was used throughout the entire area, and even as far as Egypt, for diplomatic communications during the Amarna Period.
Cuneiform
The earliest known Sumerian king whose name appears on contemporary cuneiform tablets is Enmebaragesi of Kish. Surviving records only very gradually become less fragmentary and more complete for the following reigns, but by the end of the pre-Sargonic period, it had become standard practice for each major city-state to date documents by year-names commemorating the exploits of its "lugal" (king).
