Habiru or Apiru or ˁpr.w (Egyptian) was the name given by various Sumerian, Egyptian, Akkadian, Hittite, Mitanni, and Ugaritic sources (dated, roughly, between 1800 BC and 1100 BC) to a group of people living as nomadic invaders in areas of the Fertile Crescent from Northeastern Mesopotamia and Iran to the borders of Egypt in Canaan. Depending on the source and epoch, these Habiru are variously described as nomadic or semi-nomadic, rebels, outlaws, raiders, mercenaries, and bowmen, servants, slaves, migrant laborers, etc.
