In contrary to the long and relatively well-documented reign of Ur-Nanshe, that of his son Akurgal was short and poorly known. Only six gypssum inscriptions of his have survived. One of them (FAOS 05/1, Akg 1) states that he build the Antasura of Ningirsu, while the text of the others has been destroyed. On the basis of inscriptions from his son Eanatum, however, we know that during his reign Lagash lost some of the Guedina to Umma.
