[5] He defeated Il in a territorial conflict through an alliance with Lugal-kinishe-dudu of Uruk, successor to Enshakushanna, who is in the king list.

"A clay nail found in Girsu commemorates the alliance which he concluded with Lugal-kinishe-dudu of Uruk, the oldest mention of a peace treaty between two kings that we know:[11][12] 1st line: Dinanna-ra / Dlugal-e2-muš3-ra / en-mete-na / ensi2 / lagaški-ke4 / e2-muš3 e2 ki-ag2-ga2-ne-ne / mu-ne-du3 / KIBgunû mu-na-du11 / en-mete-na / lu2 e2-muš3 du3-a 2nd line: D-ra-ni / dšul-utul12-am6 / u4-ba en-mete-na / ensi2 / lagaški / lugal-ki-ne2-eš2-du7-du7 / ensi2 / unuki-bi / nam-šeš e-ak 1st line: "For Inanna / and Lugal-emuš / Enmetena / ruler / of Lagaš, / the E-muš, their beloved temple, / built / and ordered (these) clay nails for them.

Entemena entered in a territorial conflict with Il, king of Umma, as mentioned in the "war inscription" on his cone in the Louvre Museum:[13] "He (Il, Governor of Umma) diverted water from the boundary-channel of Ningirsu and the boundary-channel of Nanshe (...).

"[13]Il was defeated by Entemena, who had sought the aid of Lugal-kinishe-dudu of Uruk, successor to Enshakushanna, who is in the king list.

[6] A foundation cone of Entemena, in excellent condition relates the beginning of a war between the city-states of Lagaš and Umma during the Early Dynastic III period, one of the earliest border conflicts recorded.

[14] This text was inscribed on a small clay cone c. 2400 BC (Louvre Museum, reference AO 3004).

[19] Entemena, although ruler of the city-state of Lagash, wears the typical dress of a devotee: a kaunakes fleeced skirt with a tassel in the back.

A frieze of lions devouring ibexes and deer, incised with great artistic skill, runs round the neck, while the eagle crest of Lagash adorns the globular part.

They usually records Entemena's name, title and filiation, and his accomplishment in establishing temples or devotional images.

[28] The plaque depicts various scenes: a standing man in a kaunakes holding a walking stick, a resting cow, and the symbol of Lagash: an eagle (Anzû) holding two lions, although the lions are uncharacteristically biting back at the wings of the eagle.
