The key to the matter is probably furnished by the following inscription of Ammi-ṭitana, the ninth king of the dynasty— “Ammi-ṭi(tana), his(?) ... the powerful king, (in) a seat of gladness king of Babylon, he has made him sit. king of Kiš, king of Šumer and (Akkad), king of the vast land of Amoria, am I; its wall. descendant Asari-lu-duga (Merodach) of Sumu-la-îli, has revealed him as his worshipper— eldest son(21) may his name be established of Abēšu’,(22) am I, in heaven and earth. Obedient(?) (to) Bel “(Inscription) of Bêl-ušallim, the seat(?)” son of ... -bi, the enchanter.” In this inscription, Ammi-ṭitana calls himself not only “king of Babylon,” and other important places in Babylonia, but “king of Amoria” (if the coining of a word for the district be allowed) also. Now, as we know from the Tel-el-Amarna tablets, Amurrū is the name that the Babylonians used for “the west,” which Assyriologists formerly read (on account of the polyphony of the Babylonian system of writing) Aḫarrū. In reality, however, this word, Amurrū, stands for the land of the Amorites, and the probability is, that the land of the Amorites belonged to the Babylonian Empire because it formed part of the original domain of the rulers of Babylonia at this time, who, if not of Amorite descent, may at least have had Amorite connections. In any case, there is but little doubt that the population of Babylonia was very mixed 2000 years before Christ. As we know from the tablets, Amorites were, during this period, numerous in Babylonia, and the god whose name is written with the characters MARTU (a common group for Amurrū)—the fact is revealed by one of the tablets of late date published by Reisner—are to be read Amurrū, and the best translation is “the Amorite god,” whose name and worship seem to have been introduced into the Babylonian Pantheon at a much earlier date, and was known to the Akkadians under the name of Martu. It is noteworthy that, in the text in question (_Mitteilungen aus den orientalischen Sammlungen_, Heft. x. pl. 139, 147-81), the Akkadian Martu and Babylonian Amurrū is called “lord of the mountain,” probably because the country of the Amorites, especially when compared with Babylonia, is mountainous.
