Gu-Edin

Location of Gu-Edin, between Umma and Lagash in Sumer.

Gu-Edin (also transcribed "Gu'edena" or "Guedena") was a fertile plain in Sumer, in modern-day Iraq. It lay between Umma and Lagash, and claims made on it by each side were a cause of the Umma-Lagash war.[1] Argument over the territory continued for around 150 years.[2]
