The Chaldean tribe had lost control of Babylonia decades before the end of the era that sometimes bears their name, and they appear to have blended into the general populace of Babylonia even before this (for example, Nabopolassar, Nebuchadnezzar II and their successors always referred to themselves as Shar Akkad and never as Shar Kaldu on inscriptions), and during the Persian Achaemenid Empire the term Chaldean ceased to refer to a race of people, and instead specifically to a social class of priests educated in classical Babylonian literature, particularly Astronomy and Astrology. By the mid Seleucid Empire (312–150 BC) period this term too had fallen from use.
