Iddin-Sin, King of Simurrum, armed with a bow and an axe, trampling a foe. Circa 2000 BCE (detail)
The Simurrum Kingdom seems to have been part of a belt of Hurrian city states in the northeastern portion of Mesopotamian area. They were often in conflict with the rulers of Ur III.
Several Kings (?, pronounced ?àr, "Shar", in Akkadian) of Simurrum are known, such as Iddin-Sin and his son Zabazuna. Various inscriptions suggest that they were contemporary with king Ishbi-Erra (1953--c.1920 BCE).
The Simurrun were regularly in conflict with the Akkadian Empire. The names of four years of the reign of Sargon of Akkad describe his campaigns against Elam, Mari, Simurrum, and Uru'a (an Elamite city-state):
One unknown year during the reign of Akkadian Empire king Naram-Sin of Akkad was recorded as "the Year when Naram-Sin was victorious against Simurrum in Kirasheniwe and took prisoner Baba the governor of Simurrum, and Dubul the ensi (ruler) of Arame".
Ka-Nisba, king of Simurrum, instigated the people of Simurrum and Lullubi to revolt. Amnili, general of [the enemy Lullubi]... made the land [rebel]... Erridu-pizir, the mighty, ling of Gutium and of the four quarters hastened [to confront] him... In a single day he captured the pass od Urbillum at Mount Mummum. Further, he captured Nirishuha.
At one point, Simurrum may have become a vassal of the Gutians. Simurrum seems to have become independent after the collapse of Ur III.
