In all probability the Babylonians consisted of what may be called the original Semites of that tract, with the Akkadians, also aboriginal, with whom they lived and had already, at the time of the dynasty of Babylon, mingled to such an extent that they must have become a homogeneous people, notwithstanding the racial differences which were probably noticeable at certain points--for example, a more strongly-marked Semitic type at Sippar and in that neighbourhood, and a more strongly-marked Akkadian type in the State to which Lagas belonged. Other invasions, however, seem to have taken place, the principal being that of the Amorites, to which allusion has already been made--an invasion which the tablets of this period indicate to have been sufficiently numerous, and which must have left its mark on the population, to all appearance increasing the Semitic preponderance, and emphasizing the type. The existence of an "Amorite tract" in the district of Sippar, and the fact that Sin-idinnam, Hammurabi's general, is designated by the characters GAL-MAR-TU, in Semitic Babylonian _Rab-Amurrî_, "chief of the Amorite(s)," are in themselves sufficient testimony to this invasion. It is noteworthy, too, that the dynasty to which Hammurabi belonged is apparently that described by Berosus as "Arabic," in which case we should have to recognize yet another invasion of Semites; but there is just the probability, that "Arabic" and "Amorite" were interchangeable terms, the Amorites being regarded as a collection of wandering hordes of whom a portion entered the country, and took possession of the government. In any case, they shared the fate of all invaders of the kind referred to, for they were speedily conquered by the superior civilization of the conquered, and became so naturalized that notwithstanding their western names, they were called by the Babylonians "the dynasty of Babylon." This Amorite element was to all appearance a sufficiently large one, as the more easily recognizable names show. Thus we have _Amurru-bani_, _Karasumia_, _Asalia_, _Kuyatum_, _Bizizana_, _Izi-idrê_, _Sumu-rak_, _Betani_, _Sar-ili (Israel)_, _Awel-Addî_ ("man of Hadad," described an Amorite,) with many others, though the different nationalities cannot always be distinguished, as many Amorites bore Babylonian names, and _vice versâ_.
