Der (Sumer) — Wikipedia

Der (Sumerian: 𒌷𒂦𒀭𒆠 uruBAD3.ANki; Akkadian: 𒌷𒂦𒀭𒆠 uruBAD3.ANki or 𒌷𒁲𒂊𒊒(𒆠) urude-e-ru(ki)) was a Sumerian city-state at the site of modern Tell Aqar near al-Badra in Iraq's Wasit Governorate. It was east of the Tigris River on the border between Sumer and Elam. At one time it was thought that it might have been ancient Durum (Sumerian: uruBAD3ki) but more recent scholarship has rebutted that. The principal god of Der was Ištaran. In the 1st millennium BC, he was also referred to as Anu rabû ("Great Anu") in Akkadian. The name of his temple at Der was Edimgalkalama.
