Аккад
Many of the more recent insights on the Akkadian Empire have come from excavations in the Upper Khabur area in modern northeastern Syria which was to become a part of Assyria after the fall of Akkad. For example, excavations at Tell Mozan (ancient Urkesh) brought to light a sealing of Tar'am-Agade, a previously unknown daughter of Naram-Sin, who was possibly married to an unidentified local "endan" (ruler). The excavators at nearby Tell Leilan (ancient Shekhna/Shubat-Enlil) have used the results from their investigations to argue that the Akkadian Empire came to an end due to a sudden drought, the so-called 4.2 kiloyear event. The impact of this climate event on Mesopotamia in general, and on the Akkadian Empire in particular, continues to be hotly debated.
