The original members of the nation of Amurru (the Amorites) were a Semitic tribe in Syria, although they probably came from Arabia. The people of Amurru were intermixed with the Hurrians. The geographical region called Amurru was in Northern Palestine with its capital at Hazor, and included the neighboring Syrian desert.
The Amurru who troubled the Egyptians of the 18th Dynasty inhabited a kingdom that included the coastal plain of Syria between Ugarit and Byblos. Amurru made up the northernmost of the three districts forming the "Land of Retenu". Two kings from the Amarna period were Abdi-Ashirta and his son Azir
