The oldest mention is found in the Akkadian Naram-Sîn poetry (1st half of the 22nd century BC), where a legendary king Pamba of Ḫatti is mentioned. In the ancient Assyrian documents of Kültepe from 1900 BC. Atti denotes a region in the Halysbogen, where several city-states were located. The population of this region were the non-Indo-European Hattier .
After the collapse of the Hittite Empire around 1180 BC The name Ḫatti passed to the Neo-Hittite states in northern Syria, especially the land around Karkamis could be called that in Neo-Assyrian sources. From here the name found its way into the Old Testament as Ḥittîm "Hittite" . Thus this name does not refer to the Bronze Age Hittites.
