sargon
   in the inscriptions, "sarra-yukin" the god has appointed the
   king; also "sarru-kinu," the legitimate king. on the death of
   shalmaneser b.c. 723, one of the assyrian generals established
   himself on the vacant throne, taking the name of "sargon," after
   that of the famous monarch, the sargon of accad, founder of the
   first semitic empire, as well as of one of the most famous
   libraries of chaldea. he forthwith began a conquering career,
   and became one of the most powerful of the assyrian monarchs. he
   is mentioned by name in the bible only in connection with the
   siege of ashdod isa. 20:1.
   
     at the very beginning of his reign he besieged and took the
   city of samaria 2 kings 17:6; 18:9-12. on an inscription found
   in the palace he built at khorsabad, near nieveh, he says, "the
   city of samaria i besieged, i took; 27,280 of its inhabitants i
   carried away; fifty chariots that were among them i collected,"
   etc. the northern kingdom he changed into an assyrian satrapy.
   he afterwards drove merodach-baladan q.v., who kept him at bay
   for twelve years, out of babylon, which he entered in triumph.
   by a succession of victories he gradually enlarged and
   consolidated the empire, which now extended from the frontiers
   of egypt in the west to the mountains of elam in the east, and
   thus carried almost to completion the ambitious designs of
   tiglath-pileser q.v.. he was murdered by one of his own
   soldiers b.c. 705 in his palace at khorsabad, after a reign of
   sixteen years, and was succeeded by his son sennacherib.
