Ekallatum

Ekallatum was an ancient Assyrian city of upper Mesopotamia. The exact location of it has not yet been identified, but it was located somewhere along the left bank of the Tigris, south of Assur.

Ekallatum, whose name means "the palace," became the capital of an Amorite dynasty related to Assyria, which was important in the 19th and 18th centuries BCE period. The history of upper Mesopotamia in this period is documented in the archives of Mari, Syria.

Its first known king was Ila-kabkabu, who seems to have entered into a conflict with Iagitlim of Mari. His son Shamshi-Adad I ascended to the throne around 1810 BCE, continuing the conflict and attempting to extend into the valley along the Khabur River. His expansion was halted by Iagitlim's son, Iakhdunlim, and he was soon after defeated by Naram-Sin of Assyria, which caused him to flee to Babylon, a city founded and ruled by fellow Amorites. He returned upon Naram-Sin's death. Soon thereafter, a series of military victories by Shamshi-Adad followed, and he seized all of Upper Mesopotamia, usurping Erishum II as king of Assyria. He founded his own capital at Shubat-Enlil, entrusting Ekallatum to his elder son Ishme-Dagan. (His other son, Yasmah-Adad, was placed on the throne of Mari at the time.) Ishme-Dagan appears to have been a capable military leader, but when his father died in around 1775, he proved unable to maintain the whole kingdom; nonetheless, he kept Ekallatum, while his brother lost Mari and was killed.
