ancient region in what is now central Iraq. Akkad was the northern (or northwestern) division of ancient Babylonian civilization. The region was located roughly in the area where the Tigris and Euphrates rivers (see Tigris-Euphrates river system) are closest to each other, and its northern limit extended beyond the line of the modern cities of Al-Fallūjah and Baghdad. The early inhabitants of this region were predominantly Semitic, and their speech is called Akkadian. To the south of the region of Akkad lay Sumer, the southern (or southeastern) division of ancient Babylonia, which was inhabited by a non-Semitic people known as Sumerians.

Under the kings of Akkad, their Semitic language, known as Akkadian (Akkadian language), became a literary language that was written with the cuneiform system of writing. Akkadian is the oldest Semitic dialect still preserved.
