There are five monarchs known to us who may be assigned to this dynasty.  The first is the Kudur-Nakhunta above named, who conquered Babylonia and established his influence there, but continued to hold his court at Susa, governing his conquest probably by means of a viceroy or tributary king.  Next to him, at no great interval, may be placed Kudur-Lagamer, the Chedor-laomer of Scripture, who held a similar position to Kudur-Nakhunta, reigning himself in Elam, while his vassals, Amraphel, Arioch, and Tidal (or Turgal) held the governments respectfully of Shinar (or Upper Babylonia), Ellasar (Lower Babylonia or Chaldaea), and the Goim or the nomadic races.  Possessing thus an authority over the whole of the alluvial plain, and being able to collect together a formidable army, Kudur-Lagamer resolved on a expedition up the Euphrates, with the object of extending his dominion to the Mediterranean Sea and to the borders of Egypt.  At first his endeavors were successful.  Together with his confederate kings, he marched as far as Palestine, where he was opposed by the native princes, Bera, king of Sodom, Birsha, king of Gomorrah, Shinab, king of Admah, Shemeber, king of Zeboiim, and the king of Bela or Zoar.  A great battle was fought between the two confederated armies in the vale of Siddim towards the lower end of the Dead Sea.  The invaders were victorious; and for twelve years Bera and his allies were content to own themselves subjects of the Elamitic king, whom they “served” for that period.  In the thirteenth year they rebelled:  a general rising of the western nations seems to have taken place; and in order to maintain his conquest it was necessary for the conqueror to make a fresh effort.  Once more the four eastern kings entered Syria, and, after various successes against minor powers, engaged a second time in the valley of Siddim with their old antagonists, whom they defeated with great slaughter; after which they plundered the chief cities belonging to them.  It was on this occasion that Lot, the nephew of Abraham, was taken prisoner.  Laden with booty of various kinds, and encumbered with a number of captives, male and female, the conquering army set out upon its march home, and had reached the neighborhood of Damascus, when it was attacked and defeated by Abraham, who with a small band ventured under cover of night to fall upon the retreating host, which he routed and pursued to some distance.  The actual slaughter can scarcely have been great; but the prisoners and the booty taken had to be surrendered; the prestige of victory was lost; and the result appears to have been that the Mesopotamian monarch relinquished his projects, and, contenting himself with the fame acquired by such distant expeditions, made no further attempt to carry his empire beyond the Euphrates.
