Gu-Edin

[2] According to a peace between Umma and Lagash mediated by Mesilim, king of Kish had determined where the boundary lay and the terms of use of a canal used to irrigate the land.

The terms of that agreement were recorded on a stone monument called a stele, but Umma continued to feel that Lagash were unfairly advantaged by it.

[2] It is recorded on the Stele of the Vultures that Gu-Edin was pillaged by a later (énsi) of Umma, who ruled that city on behalf of its god Shara, and whose name, according to the Cone of Enmetena,[a] was Ush.

[8] A deep canal was dug to mark the freshly agreed border and two stone monuments were put in place: the Stele of Mesilim, which had been there before, and a newly carved one.

[9] The treaty, which was sealed with oaths and the erection of temples, also included the establishment of an 'ownerless' tract of land intended as a buffer, and treated any barley Umma grew in that area of Gu-Edin to which it had access as a loan from Lagash, with resulting interest.
