first king of the Chaldeans or Babylonians; memorable for the Jewish era which bears his name, which is generally fixed in 3257, beginning on Wednesday, February 26th, in the 3967th of the Julian period, 747 years before Christ. The Babylonians revolting from the Medes, who had overthrown the Assyrian monarchy, did, under Nabonassar, found a dominion, which was much increased under Nebuchadnezzar. It is probable, that this Nabonassar is that Baladan in the second of Kings, xx. 12. father of Merodach, who sent ambassadors to Hezekiah. See 2 Chron. xxxii.
