[8] The name of Aga is Sumeriana and a relatively rarely attested personal name in Early Dynastic times, making his identification in royal texts spottable.

[9] His name appears in the Stele of Ushumgal, as the gal-ukkin ("Great Assembly official").b AK (𒀝) was likely an Early Dynastic spelling of Akka, (the past particle of the Sumerian verb "to make").

According to the Sumerian King List (ETCSL 2.1.1), Kish had the hegemony of Sumer where he reigned 625 years, succeeding his father Enmebaragesi to the throne, finally ending in defeat by Uruk.

[1] There is some scant evidence to suggest that like the later Ur III kings, the rulers of ED Kish sought to ingratiate themselves to the authorities in Nippur, possibly to legitimize a claim for leadership over the land of Sumer or at least part of it.

Gilgamesh repeats the message before the "city fathers" (ab-ba-iri) to suggest defiance of Aga, but the elders refuse.

[23] The guruš accept Gilgamesh's call to revolt and declare him lugal (king).c After ten days, Aga lays siege to the walls of Uruk, whose citizens are now confused and intimidated.

[25] If Gilgamesh had won a previous war against Kish, he would not have spoken with Aga of past military cooperation and indebtedness for saving his life.
