He called the Sumerians "the black-headed ones."
It is a common mistake to say that the Akkadians are a different nationality from the Sumerians, or that they were the first to call the Sumerians “black-headed people.” It is true that this name is what the Sumerians used for themselves.
But it is worth mentioning and noting that the Akkadians used the word “Kengir” for the country of the Sumerians, meaning “Country of the Noble Lords,” which means “Country of the Noble Lords,” which is the same name that the Sumerians used for their country previously and in the Akkadian era as well. Kengir, the 'Country of the noble lords' (????????????, k-en-gi(-r), lit. 'country' + 'lords' + 'noble') as seen in their inscriptions.
We understand from this that the Akkadians are the sons of the Sumerians who expanded and spread north of Sumer, but the land of the fathers in southern Mesopotamia remained sacred and the land of their fathers, the noble masters, being the first homeland and the homeland of the first sacred kingship that descended from heaven in Eridu for the first time, and the sanctification of Ur continued until the end of the era. Modern Babylonian, which additionally confirms the development of the language from the language of the Sumerian ancestors to the Akkadian language of the children, which is the natural development of societies with the progress of time. In addition to the above, the word Akkad was associated with the person of Sargon, and it was mentioned in a city from which Sargon descended, located near the city of Adab, Uma and Nefer in the land of Sumer. The truth is that the English previously, and after them the archaeologists, were unable to find its location, and so far it is only a name without a name. Whatever it is, it is perhaps a small Sumerian village among dozens of major Sumerian cities, and this does not make it a different nationality and race from the Sumerians for the reasons above. In addition to that, the dialect difference between what is known as the Akkadians. (The Sumerians in the north of the motherland of Sumer) and between their fathers in the south is a natural difference in all peoples, as is the case today between the dialect of the south and the center and between the cities of the south themselves.
