Shamshi-Adad I
He placed his sons (Ishme-Dagan I and Yasmah-Adad) in key geographical locations and gave them responsibility to look over those areas. Shamshi-Adad I put his eldest son (Ishme-Dagan I) on the throne of Ekallatum, while Shamshi-Adad I remained in Shubat-Enlil. Shamshi-Adad I put his second son, (Yasmah-Adad) on the throne in Mari. With the annexation of Mari, Shamshi-Adad I had carved out a large empire encompassing much of Syria, Anatolia, and the whole of Upper Mesopotamia. Shamshi-Adad I proclaimed himself as "King of All" (the title had been used by Sargon of the Akkadian Empire c. 2334 BCE — c. 2279 BCE.)
