This so-called second dynasty of Ur includes Nippur.

The kings are proud of calling themselves the guardians of the temple of Bel in Nippur, nominated to the office by the god himself, and reviving an old title of the kings of Agade, style themselves also 'king of the four regions.' Another change in the political horoscope is reflected in the subjection of Ur to a district whose center was Larsa, not far from Ur, and represented by the mound Senkereh.

There are two kings, Nur-Ramman (_i.e._, light of Ramman) and Sin-iddina (_i.e._, Sin judges), who call themselves guardians of Ur and kings of Larsa, showing that the center of this principality was Larsa, with Ur as a dependent district.

That these rulers take up the dominion once held by the kings of Ur is further manifest in the additional title that they give to themselves, as 'kings of Sumer and Akkad,' whereas the omission of the title 'king of the four regions' indicates apparently the exclusion of Agade and Nippur; and with these, probably North Babylonia in general, from their supremacy.
The power of Larsa receives a fatal check through the invasion of Babylonia by the Elamites (_c._ 2350 B.C.).
These variations in official titles are a reflection of the natural rivalry existing between the various Babylonian states, which led to frequent shiftings in the political situation.

Beyond this, the inscriptions of these old Babylonian rulers, being ordinarily commemorative of the dedication to a deity, of some temple or other construction--notably canals--or of some votive offering, a cone or tablet, unfortunately tell us little of the events of the time.
