Two rulers of Agade, Naram-Sin (_c._ 3800 B.C.) and Sargon (or to give his fuller name, Shargani-shar-ali[20]), are the earliest rulers as yet known.

These kings of Agade extended their jurisdiction as far north, at least, as Nippur on the one side and Sippar on the other.

The city of Babylon itself, if it existed at this period, was therefore included within the territory of these kings; and it follows that if there existed rulers of Babylon at this time, which is doubtful (since the city is not mentioned), they were in the same position of dependency upon the rulers of Agade as the 'governors' of Lagash were upon some greater power.

It is not until about the middle of the third millennium before this era, that Babylon comes into prominence.
In the south, as already intimated, the rulers of Lagash and the dynasty of Ur are the earliest of which we have any record.

There is every reason to believe that further excavations at Mugheir will bring to light the names of older kings, and the presumption is in favor of regarding the southern states, or at least some of them, earlier than any in the north.
