What is "amorites"

The Amorites (; Sumerian ???????? MAR.TU; Akkadian Tidnum or Amurrūm; Egyptian Amar; Hebrew אמורי ʼĔmōrī; ) were an ancient Semitic-speaking people from Syria who also occupied large parts of southern Mesopotamia from the 21st century BC to the end of the 17th century BC, where they established several prominent city states in existing locations, notably Babylon which was raised from a small administrative town to an independent state and major city. The term Amurru in Akkadian and Sumerian texts refers to them, as well as to their principal deity.
