Assyria loses its independence to a dynasty…
1737 BCE to 1726 BCE
Assyria loses its independence to a dynasty of Amorite descent from Terqa, a city near Mari, on the Euphrates River, when a member of this dynasty conquers Assyria and reigns from around 1740 BCE as Shamshi-Adad I, his kingdom extending from the Euphrates to the Zagros Mountains.
The capital of this Old Assyrian kingdom, called Shubat-Enlil, is founded some distance from Urkesh at another Hurrian settlement in the Khabur River valley, modern Tell Leilan.
