Until about the time of the dynasty of Babylon, the language principally used was to all appearance the non-Semitic Babylonian or Akkadian—in any case, the numerous texts (mainly temple-accounts) of the period of Dungi, Bûr-Sin, Gimil-Sin, and Ibi-Sin are written in that tongue. Nevertheless, Akkadian seems to have been the official language of the country for a considerable time after, if we may judge from the contracts, and especially the historical dates of these documents, which are always written in Akkadian. The names, too, which were before this period wholly Akkadian, gradually become more and more Semitic (Assyro-Babylonian), and finally the Akkadian element only exists as a remnant of the non-Semitic tongue which prevailed before the Semitic Dynasty of Babylon—that to which Ḫammurabi or Amraphel belonged—made the Semitic tongue, spoken by Sargon of Agadé more than 1500 years before, the official language of the country. Such, then, is the history of the ancient Akkadians, from whose intermingled stock the later Semitic Babylonians sprang, and who inherited, at the same time, their method of writing, their literature, their arts and sciences, and also, to a great extent, their manners, customs, and religion. It was to all appearance with the Semitic dynasty of Ḫammurabi that the change from non-Semitic to Semitic predominance took place. This change must have been slow enough, and in all probability it occurred without any national upheaval, and without any interruption of the national life. Semitic names gradually replaced the Akkadian ones, most of the religious works, incantations, national histories, bilingual lists, and syllabaries were supplied with Semitic translations, and legal precedents in Semitic Babylonian for the information of the judges of later times were drawn up, whilst the old Akkadian laws, though retained, were translated for the use of students who no longer learned Akkadian as their mother-tongue, and who committed them to memory at the same time as they learned the set phrases they would have to use when, their education completed, they should attain to the dignity of full-fledged ministers to the legal needs of the community. By this time, or somewhat later, the racial type must have become fixed, for the sculptures from the thirteenth century B.C. downwards no longer show the slim, elegant form of the Akkadians, but the thick-set, well-developed figure of the Semites, such as at least some of the native Christians of Baghdad and the neighbourhood show at the present day.
