“[A]ll of the old Sumerian cities . . . were part of the empire centered at Babylon. . . .

This was no unruly empire; it was ruled by law. Hammurabi managed his growing conquests, in part, by enforcing the same code over the entire extent of it. The only surviving copy of this code was discovered centuries later in Susa, carved onto a black stone stele. Clearly the laws were intended to embody a divine code of justice (the top of the stele shows the god of justice, bestowing his authority on Hammurabi), but their showy presence in conquered cities also kept control over the conquered people. According to the stele itself, the laws were observed faithfully in Nippur, Eridu, Ur, Larsa, Isin, Kish, Mari, and other cities.”
