The Ahlamu; or Aḫlamū, were a group or designation of Semitic semi-nomads. Their habitat was west of the Euphrates between the mouth of the Khabur and Palmyra.
They were first mentioned in sources of Rîm-Anum, a king of Uruk, ca. 1800 BC and then in texts from Mari and finally in the 14th century BC in Egyptian sources in one of the Amarna letters in the days of Akhenaten in which it is affirmed that the Ahlamu had advanced to the Euphrates.[1][2]
