How it came about is not known, but it is certain that, about 2200 years B.C., a purely Semitic dynasty occupied the throne of the chief ruler in Babylonia. The first king was Sumu-abi, who reigned 14 years. This monarch was followed by Sumu-la-ili and Zabû, 36 and 14 years respectively. Then come two rulers with Babylonian names—Abil-Sin and Sin-mubaliṭ, 18 years and 20 years. These are followed, in their turn, by Ḫammurabi (43), Samsu-iluna (38), Ebišum (25), Ammi-ṭitana (25), Ammi-zaduga (21), and Samsu-ṭitana (31 years). This dynasty, therefore, lasted about 285(18) years, and with two exceptions, Abil-Sin and Sin-mubaliṭ, the names, though Semitic, are not Babylonian. Yet it was called by Babylonians “the dynasty of Babylon!” And this, in all probability, is correct. The dynasty must, on account of the name given to it, have come from that city, but was, at the same time, of foreign origin, its kings being descended from another dynasty which came from some other part of the Semitic world of that time. This is indicated by the following facts. Three of the tablets of which we shall learn something more farther on, and which are preserved in the British Museum, have invocations of a personage, apparently a king, named Anmanila. The name of this ruler naturally recalls the Anman of the dynasty following that of Babylon—namely, the dynasty of Uru-ku; but the style of the writing of these three documents is not that of the later period, but of the beginning of the dynasty of Babylon, and there is, on that account, every probability that Anmanila was one of the predecessors of Sumu-abi, the first king of the dynasty of Babylon. It is, of course, possible that this ruler was simply a co-regent with one of the kings already known, like Immerum, who lived at the time of Sumu-la-îla, or Buntaḫun-îla,(19) another associate with Sumu-la-îla on the throne, but there is a certain amount of improbability in this, as Anmanila is named alone, and not in connection with any other. Moreover, it is probable that, in the case of the two co-regents here mentioned, we have examples of sons associated with their father, and one replacing the other on account of the early death of his brother. Another ruler, probably of the period preceding that of the dynasty of Babylon, is Manamaltel, whose name is found on a tablet belonging to the Rev. Dr. J. P. Way, head-master of Rossall School, and it is noteworthy that one of the tablets bearing the name of Anmanila gives, among the witnesses, a certain Sumuentel,(20) a name having the same termination as Manamaltel, a component which seems to have been common at this early period, and rare or non-existent later. Most, if not all, the above are foreign names. The next question that arises is, what was the nationality of these rulers, who, though belonging to what was called “the dynasty of Babylon,” were not really of Babylonian origin?
